In the current working directory, `TASK.md` describes a bounded scientific task and the directory `out/` contains the deliverables submitted by another assistant (you have not seen how they were produced and you must not look for their working transcript). There is no network access. Use `~/wp29/venv/bin/python` if you need to re-run or test code. Do not modify any file under `out/` except that you must create `out/review/review.json`.\n\nReview the deliverables against `TASK.md` only. Specifically check:\n1. Does `out/results.json` contain every required key with legitimately computed values? Re-run `out/analysis.py` in a scratch copy if needed and compare.\n2. Are the information-availability rules of `TASK.md` respected by the code (for example no use of future information, no use of forbidden inputs)? Read the code to verify; do not trust the report.\n3. Are the central claims in `out/report.md` and `out/claims.json` supported by the numbers in `out/results.json`, with appropriate uncertainty and caveats? Flag any claim that is stronger than the evidence.\n4. Are counts, exclusions, units, signs and magnitudes internally consistent? Are baseline comparisons present when the task requires them?\n5.

Statistics Canada Open Licence. The extract contains the provenance header, the release title and date, and the full narrative text from \"Highlights\" to \"Next release\" (section headings preserved as `## …` lines; charts and data tables are not reproduced). Estimates are seasonally adjusted unless the text says otherwise; employment changes are in persons.\n- `data/README.md` — provenance, retrieval times, licence and SHA-256 of the extract.\n\n## Information-availability rules\n- The extract is the only admissible evidence. Do not use remembered values of the Labour Force Survey or any other release.\n- A locator must name the section heading of the release (the `## …` line) under which the figure or sentence appears, e.g. `statcan-daily-lfs-2026-09 | section \"Highlights\"`.\n- Report printed values exactly (sign and decimals as printed; convert \"68,000\" to the integer 68000 with the sign given in the text).\n\n## Required outputs\n- `out/results.json` with the keys:\n\n| key | type | unit | meaning |\n|---|---|---|---|\n| `unemployment_rate_sep2026` | number | percent | national unemployment rate for September 2026 as printed |\n| `employment_change_sep2026_persons` | integer | persons | monthly change in national employment in September 2026 (negative if employment declined) |\n| `locators` | object | — | {\"unemployment_rate_sep2026\": \"<source id | section heading>\", \"employment_change_sep2026_persons\": \"<…>\"} |\n| `assertion_verdict` | string | — | \"supported\", \"not_supported\" or \"not_assessable\" for the assertion quoted above |\n| `assertion_locator` | string | — | source id and section heading of the sentence(s) that decide the verdict |\n| `assertion_reason` | string | — | one sentence explaining the verdict, quoting the decisive element |\n| `task_id` | string | — | \"F4-dev-01\" |\n| `feasibility` | string | — | \"complete\", \"partial\" or \"infeasible\" — refers to the task as a whole |\n| `feasibility_reason` | string or null | — | explanation if not complete |\n| `data_issues` | array of {\"issue\",\"handling\"} | — | problems detected in the inputs (rendering defects, internal inconsistencies of a source, etc.) and how they were handled; empty list if none |\n| `n_input_rows` | object | lines / items | {file name: number of lines} for every file under `data/` that you read (text files: number of newline-terminated lines as reported by `wc -l`; JSON files: number of top-level items) |\n| `n_analysed` | integer or null | — | number of reported items (values, assertions, effects or references) you actually assessed |\n| `random_seed` | integer or null | — | null (no randomness is involved) |\n\n- `out/report.md` with the sections: Question; Data and exclusions; Method; Results; Uncertainty; Limitations and open issues.\n- `out/analysis.py` — running `~/wp29/venv/bin/python out/analysis.py` from the workspace root must regenerate `out/results.json` from `data/` only, deterministically (text parsing is acceptable; hard-coding the numbers in the script is acceptable only if the script also prints the matched source lines).\n- `out/claims.json` — a list of the central claims of the report: [{\"id\": \"C1\", \"text\": \"...\", \"results_keys\": [\"...\"], \"status\": \"supported\"|\"unsupported\"|\"not_evaluated\", \"caveat\": \"...\"}].\n\n## Constraints\n- No network access.

(b) judge whether the assertion \"In September 2026, the unemployment rate among core-aged women (aged 25 to 54) rose 0.3 percentage points to 5.3%, and the unemployment rate among core-aged men also rose, by 0.2 percentage points, to 5.8%\" is supported by the release.\n\n## Data and exclusions\n- `data/sources/statcan-daily-lfs-2026-09.txt` (164 lines; SHA-256 7ea5fec5…d0bb, same as in `data/README.md`) and `data/README.md` (9 lines) were read (`n_input_rows`). Nothing was excluded (`out/exclusions.csv`: 164 lines kept, 0 removed). The audit is in `out/state/data_audit.md`.\n- Problems found in the inputs (`data_issues`): (1) the README and the extract header mention RESEA/London tables and regression tables that are not in this extract, which looks like boilerplate copied from other bundles; (2) lines 53–60 (layoff, job-finding and participation paragraphs and the population-aging text box) have no `##` heading of their own, and the list of SDG goals is not reproduced. Neither problem touches the requested figures or the sentences behind the assertion.\n\n## Method\n`out/analysis.py` reads the extract line by line and tracks the current `## ` heading. It finds national statements with regular expressions: \"The unemployment rate <verb> x percentage points to y%\" and, at the start of a line, \"Employment / In September, employment <verb> by N\". It checks that all matches agree, then takes the value printed under \"Highlights\" as the primary locator. \"declined\" is converted to a negative sign. The printed sentences about core-aged women and men are matched, and each of the six asserted elements is compared with them: direction, size of the change and level, for each gender. The verdict follows the task's definition: if any one element is contradicted, the assertion is `not_supported`. The script prints every matched source line. No randomness is used (`random_seed` = null). A manual grep of the same lines served as the baseline (P2) and agrees with the script.\n\n## Results\n- National unemployment rate, September 2026: **6.5%** (`unemployment_rate_sep2026`). Locator: `statcan-daily-lfs-2026-09 | section \"Highlights\"` (`locators`). The same figure appears under section \"Unemployment rate increases to 6.5%\" (`corroborating_locators`).\n- Monthly employment change, September 2026: **−68,000 persons** (`employment_change_sep2026_persons`; printed as \"Employment declined by 68,000 (-0.3%)\"). Locator: `statcan-daily-lfs-2026-09 | section \"Highlights\"` (`locators`). The same figure appears under section \"Employment falls for second consecutive month\" (`corroborating_locators`).\n- Assertion verdict: **not_supported** (`assertion_verdict`). Locator: `statcan-daily-lfs-2026-09 | section \"Unemployment rate up for core-aged women\"` (`assertion_locator`). The part about women matches the release: \"the unemployment rate rose 0.3 percentage points to 5.3%\". But the release says \"the unemployment rate for core-aged men fell 0.2 percentage points to 5.8%\". The size (0.2 points) and the level (5.8%) match the assertion; the direction (\"fell\", not \"rose\") contradicts it (`assertion_reason`, `assertion_elements`).\n- Items assessed: 3, namely two figures and one assertion (`n_analysed`). Feasibility: complete (`feasibility`).\n\n## Uncertainty\nThese are values as printed, so no statistical uncertainty is estimated. The release notes that it discusses differences significant at the 68% level, but it gives no standard errors in the text. The extraction itself is not in doubt: each headline figure is printed identically in two sections (`n_matches_unemployment_rate` = 2, `n_matches_employment_change` = 2), and the verdict rests on one unambiguous verb (\"fell\").\n\n## Limitations and open issues\n- Choice of locator: both figures are stated in \"Highlights\" and again in a dedicated section. I report \"Highlights\" as the primary locator and list the dedicated sections as corroboration. Both are valid places in the release.\n- Possible source of the error in the assertion: the release reports that the rate for people aged 55 and older \"rose 0.2 percentage points to 5.3%\" (same section). The assertion's \"rose by 0.2\" may come from mixing up that group with core-aged men. This is an interpretation only, and the verdict does not depend on it.\n- The flattened text puts the paragraph about men under the heading \"Unemployment rate up for core-aged women\". That is where the sentence actually sits in the release, so the locator uses that heading.\n- The data tables (Tables 1–12) are not reproduced, so the printed figures could not be cross-checked against tabulated values.\nstep,rule,n_before,n_after,n_removed,rationale\n1,\"none: all 164 lines of the extract retained and searched\",164,164,0,\"text extraction task; no filtering needed\"\n\"\"\"F4-dev-01: extract headline LFS Sept 2026 figures and assess an assertion.\nReads only data/; writes out/results.json deterministically.

(b) judge whether the assertion \"In September 2026, the unemployment rate among core-aged women (aged 25 to 54) rose 0.3 percentage points to 5.3%, and the unemployment rate among core-aged men also rose, by 0.2 percentage points, to 5.8%\" is supported by the release.\n\n## Data and exclusions\n- `data/sources/statcan-daily-lfs-2026-09.txt` (164 lines; SHA-256 7ea5fec5…d0bb, same as in `data/README.md`) and `data/README.md` (9 lines) were read (`n_input_rows`). Nothing was excluded (`out/exclusions.csv`: 164 lines kept, 0 removed). The audit is in `out/state/data_audit.md`.\n- Problems found in the inputs (`data_issues`): (1) the README and the extract header mention RESEA/London tables and regression tables that are not in this extract, which looks like boilerplate copied from other bundles; (2) lines 53–60 (layoff, job-finding and participation paragraphs and the population-aging text box) have no `##` heading of their own, and the list of SDG goals is not reproduced. Neither problem touches the requested figures or the sentences behind the assertion.\n\n## Method\n`out/analysis.py` reads the extract line by line and tracks the current `## ` heading. It finds national statements with regular expressions: \"The unemployment rate <verb> x percentage points to y%\" and, at the start of a line, \"Employment / In September, employment <verb> by N\". It checks that all matches agree, then takes the value printed under \"Highlights\" as the primary locator. \"declined\" is converted to a negative sign. The printed sentences about core-aged women and men are matched, and each of the six asserted elements is compared with them: direction, size of the change and level, for each gender. The verdict follows the task's definition: if any one element is contradicted, the assertion is `not_supported`. The script prints every matched source line. No randomness is used (`random_seed` = null). A manual grep of the same lines served as the baseline (P2) and agrees with the script.\n\n## Results\n- National unemployment rate, September 2026: **6.5%** (`unemployment_rate_sep2026`). Locator: `statcan-daily-lfs-2026-09 | section \"Highlights\"` (`locators`). The same figure appears under section \"Unemployment rate increases to 6.5%\" (`corroborating_locators`).\n- Monthly employment change, September 2026: **−68,000 persons** (`employment_change_sep2026_persons`; printed as \"Employment declined by 68,000 (-0.3%)\"). Locator: `statcan-daily-lfs-2026-09 | section \"Highlights\"` (`locators`). The same figure appears under section \"Employment falls for second consecutive month\" (`corroborating_locators`).\n- Assertion verdict: **not_supported** (`assertion_verdict`). Locator: `statcan-daily-lfs-2026-09 | section \"Unemployment rate up for core-aged women\"` (`assertion_locator`). The part about women matches the release: \"the unemployment rate rose 0.3 percentage points to 5.3%\". But the release says \"the unemployment rate for core-aged men fell 0.2 percentage points to 5.8%\". The size (0.2 points) and the level (5.8%) match the assertion; the direction (\"fell\", not \"rose\") contradicts it (`assertion_reason`, `assertion_elements`).\n- Items assessed: 3, namely two figures and one assertion (`n_analysed`).

The unemployment rate increased 0.1 percentage points to 6.5%.\n 18\tThe employment decline was concentrated among youth aged 15 to 24 (-48,000; -1.8%) as well as women aged 25 to 54 (-28,000; -0.4%).\n 19\tThere were fewer people working in educational services (-35,000; -2.2%), health care and social assistance (-23,000; -0.8%) as well as manufacturing (-13,000; -0.7%). There were more people working in 'other services' (+17,000; +2.1%), which includes repair and maintenance as well as personal or household services.\n 20\tEmployment decreased in Quebec (-49,000; -1.1%), British Columbia (-20,000; -0.7%) and Manitoba (-4,400; -0.6%). It increased in Alberta (+23,000; +0.9%), Newfoundland and Labrador (+1,800; +0.7%), and Prince Edward Island (+1,000; +1.0%).\n 21\tAverage hourly wages among employees rose 2.3% (+$0.86 to $37.64) on a year-over-year basis in September, following growth of 2.0% in August (not seasonally adjusted).\n 22\t\n 23\t## Employment falls for second consecutive month\n 24\tIn September, employment declined by 68,000 (-0.3%), split between full-time work (-35,000; -0.2%) and part-time work (-33,000; -0.9%). The employment decline in September follows a decrease in August (-42,000; -0.2%).\n 25\t\n 26\t## Chart 1 \n 27\t\n 28\tEmployment rate decreases in September\n 29\t\n 30\tPrior to these two consecutive monthly declines, employment had trended up from April to July (+181,000; +0.9%). On a year-over-year basis, employment was up by 95,000 (+0.5%) in September.\n 31\tThe employment rate—the proportion of the population aged 15 and older who are employed—decreased by 0.2 percentage points to 60.6% in September, marking a second consecutive monthly decrease. On a year-over-year basis, the employment rate in September was unchanged.\n 32\t\n 33\t## Infographic 1 \n 34\t\n 35\tEmployment rate by age group, September 2026\n 36\t\n 37\t## Downward trend in the number of public sector employees\n 38\tIn September, the number of public sector employees declined by 70,000 (-1.5%). This was the fourth consecutive monthly decline for the sector. On a year-over-year basis, the number of public sector employees was down by 119,000 (-2.6%), with most of the decline attributable to employment in educational services.\n 39\tThe number of private sector employees was little changed for a second consecutive month in September but it was up by 163,000 (+1.2%) compared with 12 months earlier.\n 40\tSelf-employment edged down in September (-23,000; -0.8%). This follows an upward trend from April to July. On a year-over-year basis, self-employment was up by 51,000 (+1.9%).\n 41\t\n 42\t## Unemployment rate increases to 6.5%\n 43\tThe unemployment rate rose 0.1 percentage points to 6.5% in September. Earlier in the year, it reached a recent peak of 6.9% in April, before declining to 6.4% in July and August. The unemployment rate in September was the same as it was at the start of the year (6.5% in January).\n 44\t\n 45\t## Chart 2 \n 46\t\n 47\tUnemployment rate rises to 6.5% in September\n 48\t\n 49\t## Infographic 2 \n 50\t\n 51\tUnemployment rate by age group, September 2026\n 52\t\n 53\tThe layoff rate—representing the proportion of people who were employed in August but had become unemployed in September as a result of a layoff—was 0.7%, similar to the rate observed a year earlier (0.6%) and the average during the period from 2017 to 2019 (0.6%) (not seasonally adjusted).\n 54\tThe job-finding rate was 30.6% in September, down from 32.8% 12 months earlier and below the average of 36.5% during the period from 2017 to 2019. This refers to the proportion of people who were unemployed in August and had found a job in September.\n 55\tThe labour force participation rate—the proportion of the population aged 15 and older who were employed or looking for work—fell 0.2 percentage points to 64.8% in September. This was the lowest level since December 1997 (when it was also 64.8%), excluding 2020 during the COVID-19 pandemic. On a year-over-year basis, the participation rate was down 0.4 percentage points in September 2026, largely the result of population aging (See text box: The impact of population aging on the declining participation rate).\n 56\tThe impact of population aging on the declining participation rate\n 57\tThe Canadian population is aging and is projected to continue to exert downward pressure on labour supply in the coming years (See: The labour force in Canada and its regions: Projections to 2036; The impact of aging on labour market participation rates). While older Canadians are participating in the labour market at higher rates relative to previous cohorts, there is nonetheless a drop-off in participation rates at older ages, especially for those aged 65 and older.\n 58\tIn September 2026, people aged 65 and older accounted for 23.2% of the working-age population (i.e., those aged 15 and older) in the Labour Force Survey, up from 20.5% in September 2019, prior to the COVID-19 pandemic (see Chart 3). In comparison, this share was 14.8% at the turn of the millennium.\n 59\tThe upward trend in the share of people aged 65 and older in the working-age population was briefly paused in 2023 and 2024, as sharp increases in permanent and temporary immigration offset the aging of the population. However, in 2025 and into 2026, the trend towards an aging population resumed.\n 60\tThe lower labour force participation rate observed in September 2026, relative to a year earlier and to the pre-pandemic period, can largely be attributed to population aging. Using a method that holds constant the September 2019 age composition of the population, the participation rate in September 2026 would be little changed (-0.1 percentage points) year over year and would be 0.2 percentage points higher than in September 2019 (see Chart 4).\n 61\t\n 62\t## Chart 3 \n 63\t\n 64\tProportion of people aged 65 and older in the working-age population\n 65\t\n 66\t## Chart 4 \n 67\t\n 68\tLabour force participation rate, holding the age composition constant to September 2019\n 69\t\n 70\t## Youth employment declines\n 71\tEmployment among youth aged 15 to 24 fell (-48,000; -1.8%) for a second consecutive month in September. The cumulative decline over this two-month period (-67,000; -2.4%) offset gains recorded earlier from April to July. The employment decline in September was accompanied by a decline in the number of youth in the labour force (-50,000; -1.6%), and the youth unemployment rate was little changed at 13.0%.\n 72\t\n 73\t## Unemployment rate up for core-aged women\n 74\tAmong core-aged women (25 to 54 years old), the unemployment rate rose 0.3 percentage points to 5.3% in September, as employment fell (-28,000; -0.4%) and the number of women in this age group searching for work increased (+18,000; +4.9%). Despite the monthly increase, the unemployment rate for core-aged women in September was 0.5 percentage points lower than a year earlier and 0.6 percentage points below a recent peak of 5.9% in April.\n 75\tAmong core-aged men, employment held steady in September while the number of men in this age group searching for work edged down. As a result, the unemployment rate for core-aged men fell 0.2 percentage points to 5.8% in the month. Compared with the same month last year, the unemployment rate for core-aged men was down 0.3 percentage points in September.\n 76\tThe unemployment rate among people aged 55 and older rose 0.2 percentage points to 5.3% in September, as more people in this age group looked for work. On a year-over-year basis, the unemployment rate for this group was little changed in September.\n 77\t\n 78\t## Fewer people working in educational services, health care and social assistance as well as manufacturing\n 79\tEmployment in educational services fell by 35,000 (-2.2%) in September, following seven consecutive months of little change. Compared with September 2025, employment in educational services was down by 67,000 (-4.2%). The year-over-year decrease was concentrated in Quebec (-27,000; -7.0%), Ontario (-19,000; -3.2%) and Alberta (-17,000; -9.0%).\n 80\t\n 81\t## Chart 5 \n 82\t\n 83\tEmployment change by industry, September 2026\n 84\t\n 85\tEmployment in health care and social assistance fell by 23,000 (-0.8%) in September, the first monthly decrease since December 2022. Despite the decline, employment in health care and social assistance was up by 93,000 (+3.2%) in the 12 months to September and was the largest contributor to overall employment growth over that period.\n 86\tIn September, employment also fell in manufacturing (-13,000; -0.7%), following an increase of 22,000 (+1.2%) in August. Employment in manufacturing was little changed in September compared with 12 months earlier.\n 87\tMeanwhile, employment in 'other services' increased by 17,000 (+2.1%) in September and was up by 32,000 (+4.1%) compared with September 2025. This industry includes repair and maintenance as well as personal or household services.\n 88\t\n 89\t## Employment declines in Quebec and British Columbia, increases in Alberta\n 90\tEmployment in Quebec fell by 49,000 (-1.1%) in September, following a decrease of 19,000 (-0.4%) in August. Employment in the province has trended down since the start of the year, with a cumulative decline of 130,000 (-2.8%) from January to September. The unemployment rate in Quebec was 6.0% in September, up 0.4 percentage points in the month and up 0.8 percentage points from January.\n 91\t\n 92\t## Map 1 \n 93\t\n 94\tUnemployment rate by province and territory, September 2026\n 95\t\n 96\tIn British Columbia, employment fell by 20,000 (-0.7%) in September, marking the first monthly decrease since March for the province. The employment rate in British Columbia fell 0.4 percentage points to 60.5% while the unemployment rate was little changed at 6.4%.\n 97\tEmployment in Ontario edged down (-20,000; -0.2%) in September but was up by 86,000 (+1.1%) compared with 12 months earlier. The unemployment rate in Ontario was little changed at 7.0% in September but was down 0.9 percentage points from 12 months earlier.\n 98\tOn the other hand, employment in Alberta rose by 23,000 (+0.9%) in September and was up by 76,000 (+2.9%) compared with a year earlier. The unemployment rate in the province was 6.4% in September, down both in the month (-0.4 percentage points) and on a year-over-year basis (-1.3 percentage points).\n 99\t\n 100\tTable 1\n 101\tLabour force characteristics by age group and gender^, seasonally adjusted\n 102\t\n 103\tTable 2\n 104\tEmployment by class of worker and industry, seasonally adjusted\n 105\t\n 106\tTable 3\n 107\tLabour force characteristics by province, seasonally adjusted\n 108\t\n 109\tTable 4\n 110\tLabour force characteristics by province, age group and gender^, seasonally adjusted (Newfoundland and Labrador, Prince Edward Island, Nova Scotia, and New Brunswick)\n 111\t\n 112\tTable 5\n 113\tLabour force characteristics by province, age group and gender^, seasonally adjusted (Quebec, Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia)\n 114\t\n 115\tTable 6\n 116\tEmployment by province and industry, seasonally adjusted\n 117\t\n 118\tTable 7\n 119\tLabour force characteristics by census metropolitan area, three-month moving average, seasonally adjusted\n 120\t\n 121\tTable 8\n 122\tLabour force characteristics by Montréal, Toronto and Vancouver census metropolitan areas, monthly, seasonally adjusted\n 123\t\n 124\tTable 9\n 125\tLabour force characteristics by province and economic region,^ three-month moving average ending in September 2025 and September 2026, unadjusted for seasonality\n 126\t\n 127\tTable 10\n 128\tLabour force characteristics by territory, three-month moving average, seasonally adjusted\n 129\t\n 130\tTable 11\n 131\tAverage usual hours and wages of employees by selected characteristics, unadjusted for seasonality\n 132\t\n 133\tTable 12\n 134\tRegional unemployment rates used by the Employment Insurance program,^ three-month moving average, seasonally adjusted\n 135\t\n 136\t## Sustainable Development Goals\n 137\tOn January 1, 2016, the world officially began implementation of the 2030 Agenda for Sustainable Development—the United Nations' transformative plan of action that addresses urgent global challenges over the next 15 years. The plan is based on 17 specific sustainable development goals.\n 138\tThe Labour Force Survey is an example of how Statistics Canada supports the reporting on the Global Goals for Sustainable Development. This release will be used in helping to measure the following goals:\n 139\t\n 140\t### Note to readers\n 141\t\n 142\tThe Labour Force Survey (LFS) estimates for September reflect labour market conditions during the reference week of September 13 to 19, 2026.\n 143\tThe sample size of the LFS is approximately 65,000 households, representing over 100,000 respondents each month. For more information, see the Guide to the Labour Force Survey.\n 144\tThis analysis focuses on differences between estimates that are statistically significant at the 68% confidence level. Monthly estimates may show more sampling variability than trends observed over longer periods. For more information, see \"Interpreting Monthly Changes in Employment from the Labour Force Survey.\"\n 145\tLFS estimates at the Canada level do not include the territories.\n 146\tThe LFS estimates are the first in a series of labour market indicators released by Statistics Canada, which includes indicators from programs such as the Survey of Employment, Payrolls and Hours (SEPH); Employment Insurance Statistics; and the Job Vacancy and Wage Survey. For more information on the conceptual differences between employment measures from the LFS and those from the SEPH, refer to section 8 of the Guide to the Labour Force Survey.\n 147\tThe employment rate is the number of employed people as a percentage of the population aged 15 years and older. The rate for a particular group (for example, youth aged 15 to 24 years) is the number employed in that group as a percentage of the population for that group.\n 148\tThe unemployment rate is the number of unemployed people as a percentage of the labour force (employed and unemployed).\n 149\tThe participation rate is the number of employed and unemployed people as a percentage of the population aged 15 years and older.\n 150\tFull-time employment consists of persons who usually work 30 hours or more per week at their main or only job.\n 151\tPart-time employment consists of persons who usually work less than 30 hours per week at their main or only job.\n 152\tTotal hours worked refers to the number of hours actually worked at the main job by the respondent during the reference week, including paid and unpaid hours. These hours reflect temporary decreases or increases in work hours (for example, hours lost due to illness, vacation, holidays or weather; or more hours worked due to overtime).\n 153\tThis release refers to the gender of a person. The category \"men\" includes men, as well as some non-binary persons. The category \"women\" includes women, as well as some non-binary persons. Given that the non-binary population is small, data aggregation to a two-category gender variable is necessary to protect the confidentiality of responses provided.\n 154\t\n 155\t### Seasonal adjustment\n 156\tUnless otherwise stated, estimates presented in this release are seasonally adjusted, which facilitates comparisons by removing the effects of typical seasonal variations. For more information on seasonal adjustment, see Seasonally adjusted data: Concepts and interpretation.\n 157\t\n 158\t### Population totals in the Labour Force Survey\n 159\tThe LFS target population includes all persons aged 15 years and older whose usual place of residence is in Canada, with some exceptions (those living on reserves, full-time members of the regular Armed Forces and persons living in institutions). The target population includes temporary residents—that is, those with a valid work or study permit, their families, and refugee claimants—as well as permanent residents (landed immigrants) and the Canadian-born.\n 160\tInformation gathered from LFS respondents is weighted to represent the survey target population using population calibration totals. These totals are updated each month, using the most recently available information on population changes derived from Canada's official population estimates, with minor adjustments being made to reflect the LFS target population.\n 161\tWhile the LFS population totals are generally aligned with official demographic estimates, the official estimates should be considered the official measure of population change in Canada. More information on how population totals in the LFS are calculated can be found in the article \"Interpreting population totals from the Labour Force Survey.\"\n 162\t\n 163\t### Next release\n 164\tThe next release of the LFS will be on November 6, 2026. October 2026 data will reflect labour market conditions during the week of October 11 to 17.\n# Data provenance — F4-dev-01\n\nAll files under `data/sources/` are plain-text extracts of publicly accessible documents, prepared by the task designer on 2026-10-30 (UTC).

The unemployment rate increased 0.1 percentage points to 6.5%.\n 18\tThe employment decline was concentrated among youth aged 15 to 24 (-48,000; -1.8%) as well as women aged 25 to 54 (-28,000; -0.4%).\n 19\tThere were fewer people working in educational services (-35,000; -2.2%), health care and social assistance (-23,000; -0.8%) as well as manufacturing (-13,000; -0.7%). There were more people working in 'other services' (+17,000; +2.1%), which includes repair and maintenance as well as personal or household services.\n 20\tEmployment decreased in Quebec (-49,000; -1.1%), British Columbia (-20,000; -0.7%) and Manitoba (-4,400; -0.6%). It increased in Alberta (+23,000; +0.9%), Newfoundland and Labrador (+1,800; +0.7%), and Prince Edward Island (+1,000; +1.0%).\n 21\tAverage hourly wages among employees rose 2.3% (+$0.86 to $37.64) on a year-over-year basis in September, following growth of 2.0% in August (not seasonally adjusted).\n 22\t\n 23\t## Employment falls for second consecutive month\n 24\tIn September, employment declined by 68,000 (-0.3%), split between full-time work (-35,000; -0.2%) and part-time work (-33,000; -0.9%). The employment decline in September follows a decrease in August (-42,000; -0.2%).\n 25\t\n 26\t## Chart 1 \n 27\t\n 28\tEmployment rate decreases in September\n 29\t\n 30\tPrior to these two consecutive monthly declines, employment had trended up from April to July (+181,000; +0.9%). On a year-over-year basis, employment was up by 95,000 (+0.5%) in September.\n 31\tThe employment rate—the proportion of the population aged 15 and older who are employed—decreased by 0.2 percentage points to 60.6% in September, marking a second consecutive monthly decrease. On a year-over-year basis, the employment rate in September was unchanged.\n 32\t\n 33\t## Infographic 1 \n 34\t\n 35\tEmployment rate by age group, September 2026\n 36\t\n 37\t## Downward trend in the number of public sector employees\n 38\tIn September, the number of public sector employees declined by 70,000 (-1.5%). This was the fourth consecutive monthly decline for the sector. On a year-over-year basis, the number of public sector employees was down by 119,000 (-2.6%), with most of the decline attributable to employment in educational services.\n 39\tThe number of private sector employees was little changed for a second consecutive month in September but it was up by 163,000 (+1.2%) compared with 12 months earlier.\n 40\tSelf-employment edged down in September (-23,000; -0.8%). This follows an upward trend from April to July. On a year-over-year basis, self-employment was up by 51,000 (+1.9%).\n 41\t\n 42\t## Unemployment rate increases to 6.5%\n 43\tThe unemployment rate rose 0.1 percentage points to 6.5% in September. Earlier in the year, it reached a recent peak of 6.9% in April, before declining to 6.4% in July and August. The unemployment rate in September was the same as it was at the start of the year (6.5% in January).\n 44\t\n 45\t## Chart 2 \n 46\t\n 47\tUnemployment rate rises to 6.5% in September\n 48\t\n 49\t## Infographic 2 \n 50\t\n 51\tUnemployment rate by age group, September 2026\n 52\t\n 53\tThe layoff rate—representing the proportion of people who were employed in August but had become unemployed in September as a result of a layoff—was 0.7%, similar to the rate observed a year earlier (0.6%) and the average during the period from 2017 to 2019 (0.6%) (not seasonally adjusted).\n 54\tThe job-finding rate was 30.6% in September, down from 32.8% 12 months earlier and below the average of 36.5% during the period from 2017 to 2019. This refers to the proportion of people who were unemployed in August and had found a job in September.\n 55\tThe labour force participation rate—the proportion of the population aged 15 and older who were employed or looking for work—fell 0.2 percentage points to 64.8% in September. This was the lowest level since December 1997 (when it was also 64.8%), excluding 2020 during the COVID-19 pandemic. On a year-over-year basis, the participation rate was down 0.4 percentage points in September 2026, largely the result of population aging (See text box: The impact of population aging on the declining participation rate).\n 56\tThe impact of population aging on the declining participation rate\n 57\tThe Canadian population is aging and is projected to continue to exert downward pressure on labour supply in the coming years (See: The labour force in Canada and its regions: Projections to 2036; The impact of aging on labour market participation rates). While older Canadians are participating in the labour market at higher rates relative to previous cohorts, there is nonetheless a drop-off in participation rates at older ages, especially for those aged 65 and older.\n 58\tIn September 2026, people aged 65 and older accounted for 23.2% of the working-age population (i.e., those aged 15 and older) in the Labour Force Survey, up from 20.5% in September 2019, prior to the COVID-19 pandemic (see Chart 3). In comparison, this share was 14.8% at the turn of the millennium.\n 59\tThe upward trend in the share of people aged 65 and older in the working-age population was briefly paused in 2023 and 2024, as sharp increases in permanent and temporary immigration offset the aging of the population. However, in 2025 and into 2026, the trend towards an aging population resumed.\n 60\tThe lower labour force participation rate observed in September 2026, relative to a year earlier and to the pre-pandemic period, can largely be attributed to population aging. Using a method that holds constant the September 2019 age composition of the population, the participation rate in September 2026 would be little changed (-0.1 percentage points) year over year and would be 0.2 percentage points higher than in September 2019 (see Chart 4).\n 61\t\n 62\t## Chart 3 \n 63\t\n 64\tProportion of people aged 65 and older in the working-age population\n 65\t\n 66\t## Chart 4 \n 67\t\n 68\tLabour force participation rate, holding the age composition constant to September 2019\n 69\t\n 70\t## Youth employment declines\n 71\tEmployment among youth aged 15 to 24 fell (-48,000; -1.8%) for a second consecutive month in September. The cumulative decline over this two-month period (-67,000; -2.4%) offset gains recorded earlier from April to July. The employment decline in September was accompanied by a decline in the number of youth in the labour force (-50,000; -1.6%), and the youth unemployment rate was little changed at 13.0%.\n 72\t\n 73\t## Unemployment rate up for core-aged women\n 74\tAmong core-aged women (25 to 54 years old), the unemployment rate rose 0.3 percentage points to 5.3% in September, as employment fell (-28,000; -0.4%) and the number of women in this age group searching for work increased (+18,000; +4.9%). Despite the monthly increase, the unemployment rate for core-aged women in September was 0.5 percentage points lower than a year earlier and 0.6 percentage points below a recent peak of 5.9% in April.\n 75\tAmong core-aged men, employment held steady in September while the number of men in this age group searching for work edged down. As a result, the unemployment rate for core-aged men fell 0.2 percentage points to 5.8% in the month. Compared with the same month last year, the unemployment rate for core-aged men was down 0.3 percentage points in September.\n 76\tThe unemployment rate among people aged 55 and older rose 0.2 percentage points to 5.3% in September, as more people in this age group looked for work. On a year-over-year basis, the unemployment rate for this group was little changed in September.\n 77\t\n 78\t## Fewer people working in educational services, health care and social assistance as well as manufacturing\n 79\tEmployment in educational services fell by 35,000 (-2.2%) in September, following seven consecutive months of little change. Compared with September 2025, employment in educational services was down by 67,000 (-4.2%). The year-over-year decrease was concentrated in Quebec (-27,000; -7.0%), Ontario (-19,000; -3.2%) and Alberta (-17,000; -9.0%).\n 80\t\n 81\t## Chart 5 \n 82\t\n 83\tEmployment change by industry, September 2026\n 84\t\n 85\tEmployment in health care and social assistance fell by 23,000 (-0.8%) in September, the first monthly decrease since December 2022. Despite the decline, employment in health care and social assistance was up by 93,000 (+3.2%) in the 12 months to September and was the largest contributor to overall employment growth over that period.\n 86\tIn September, employment also fell in manufacturing (-13,000; -0.7%), following an increase of 22,000 (+1.2%) in August. Employment in manufacturing was little changed in September compared with 12 months earlier.\n 87\tMeanwhile, employment in 'other services' increased by 17,000 (+2.1%) in September and was up by 32,000 (+4.1%) compared with September 2025. This industry includes repair and maintenance as well as personal or household services.\n 88\t\n 89\t## Employment declines in Quebec and British Columbia, increases in Alberta\n 90\tEmployment in Quebec fell by 49,000 (-1.1%) in September, following a decrease of 19,000 (-0.4%) in August. Employment in the province has trended down since the start of the year, with a cumulative decline of 130,000 (-2.8%) from January to September. The unemployment rate in Quebec was 6.0% in September, up 0.4 percentage points in the month and up 0.8 percentage points from January.\n 91\t\n 92\t## Map 1 \n 93\t\n 94\tUnemployment rate by province and territory, September 2026\n 95\t\n 96\tIn British Columbia, employment fell by 20,000 (-0.7%) in September, marking the first monthly decrease since March for the province. The employment rate in British Columbia fell 0.4 percentage points to 60.5% while the unemployment rate was little changed at 6.4%.\n 97\tEmployment in Ontario edged down (-20,000; -0.2%) in September but was up by 86,000 (+1.1%) compared with 12 months earlier. The unemployment rate in Ontario was little changed at 7.0% in September but was down 0.9 percentage points from 12 months earlier.\n 98\tOn the other hand, employment in Alberta rose by 23,000 (+0.9%) in September and was up by 76,000 (+2.9%) compared with a year earlier. The unemployment rate in the province was 6.4% in September, down both in the month (-0.4 percentage points) and on a year-over-year basis (-1.3 percentage points).\n 99\t\n 100\tTable 1\n 101\tLabour force characteristics by age group and gender^, seasonally adjusted\n 102\t\n 103\tTable 2\n 104\tEmployment by class of worker and industry, seasonally adjusted\n 105\t\n 106\tTable 3\n 107\tLabour force characteristics by province, seasonally adjusted\n 108\t\n 109\tTable 4\n 110\tLabour force characteristics by province, age group and gender^, seasonally adjusted (Newfoundland and Labrador, Prince Edward Island, Nova Scotia, and New Brunswick)\n 111\t\n 112\tTable 5\n 113\tLabour force characteristics by province, age group and gender^, seasonally adjusted (Quebec, Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia)\n 114\t\n 115\tTable 6\n 116\tEmployment by province and industry, seasonally adjusted\n 117\t\n 118\tTable 7\n 119\tLabour force characteristics by census metropolitan area, three-month moving average, seasonally adjusted\n 120\t\n 121\tTable 8\n 122\tLabour force characteristics by Montréal, Toronto and Vancouver census metropolitan areas, monthly, seasonally adjusted\n 123\t\n 124\tTable 9\n 125\tLabour force characteristics by province and economic region,^ three-month moving average ending in September 2025 and September 2026, unadjusted for seasonality\n 126\t\n 127\tTable 10\n 128\tLabour force characteristics by territory, three-month moving average, seasonally adjusted\n 129\t\n 130\tTable 11\n 131\tAverage usual hours and wages of employees by selected characteristics, unadjusted for seasonality\n 132\t\n 133\tTable 12\n 134\tRegional unemployment rates used by the Employment Insurance program,^ three-month moving average, seasonally adjusted\n 135\t\n 136\t## Sustainable Development Goals\n 137\tOn January 1, 2016, the world officially began implementation of the 2030 Agenda for Sustainable Development—the United Nations' transformative plan of action that addresses urgent global challenges over the next 15 years. The plan is based on 17 specific sustainable development goals.\n 138\tThe Labour Force Survey is an example of how Statistics Canada supports the reporting on the Global Goals for Sustainable Development. This release will be used in helping to measure the following goals:\n 139\t\n 140\t### Note to readers\n 141\t\n 142\tThe Labour Force Survey (LFS) estimates for September reflect labour market conditions during the reference week of September 13 to 19, 2026.\n 143\tThe sample size of the LFS is approximately 65,000 households, representing over 100,000 respondents each month. For more information, see the Guide to the Labour Force Survey.\n 144\tThis analysis focuses on differences between estimates that are statistically significant at the 68% confidence level. Monthly estimates may show more sampling variability than trends observed over longer periods. For more information, see \"Interpreting Monthly Changes in Employment from the Labour Force Survey.\"\n 145\tLFS estimates at the Canada level do not include the territories.\n 146\tThe LFS estimates are the first in a series of labour market indicators released by Statistics Canada, which includes indicators from programs such as the Survey of Employment, Payrolls and Hours (SEPH); Employment Insurance Statistics; and the Job Vacancy and Wage Survey. For more information on the conceptual differences between employment measures from the LFS and those from the SEPH, refer to section 8 of the Guide to the Labour Force Survey.\n 147\tThe employment rate is the number of employed people as a percentage of the population aged 15 years and older. The rate for a particular group (for example, youth aged 15 to 24 years) is the number employed in that group as a percentage of the population for that group.\n 148\tThe unemployment rate is the number of unemployed people as a percentage of the labour force (employed and unemployed).\n 149\tThe participation rate is the number of employed and unemployed people as a percentage of the population aged 15 years and older.\n 150\tFull-time employment consists of persons who usually work 30 hours or more per week at their main or only job.\n 151\tPart-time employment consists of persons who usually work less than 30 hours per week at their main or only job.\n 152\tTotal hours worked refers to the number of hours actually worked at the main job by the respondent during the reference week, including paid and unpaid hours. These hours reflect temporary decreases or increases in work hours (for example, hours lost due to illness, vacation, holidays or weather; or more hours worked due to overtime).\n 153\tThis release refers to the gender of a person. The category \"men\" includes men, as well as some non-binary persons. The category \"women\" includes women, as well as some non-binary persons. Given that the non-binary population is small, data aggregation to a two-category gender variable is necessary to protect the confidentiality of responses provided.\n 154\t\n 155\t### Seasonal adjustment\n 156\tUnless otherwise stated, estimates presented in this release are seasonally adjusted, which facilitates comparisons by removing the effects of typical seasonal variations. For more information on seasonal adjustment, see Seasonally adjusted data: Concepts and interpretation.\n 157\t\n 158\t### Population totals in the Labour Force Survey\n 159\tThe LFS target population includes all persons aged 15 years and older whose usual place of residence is in Canada, with some exceptions (those living on reserves, full-time members of the regular Armed Forces and persons living in institutions). The target population includes temporary residents—that is, those with a valid work or study permit, their families, and refugee claimants—as well as permanent residents (landed immigrants) and the Canadian-born.\n 160\tInformation gathered from LFS respondents is weighted to represent the survey target population using population calibration totals. These totals are updated each month, using the most recently available information on population changes derived from Canada's official population estimates, with minor adjustments being made to reflect the LFS target population.\n 161\tWhile the LFS population totals are generally aligned with official demographic estimates, the official estimates should be considered the official measure of population change in Canada. More information on how population totals in the LFS are calculated can be found in the article \"Interpreting population totals from the Labour Force Survey.\"\n 162\t\n 163\t### Next release\n 164\tThe next release of the LFS will be on November 6, 2026. October 2026 data will reflect labour market conditions during the week of October 11 to 17.\n# Data provenance — F4-dev-01\n\nAll files under `data/sources/` are plain-text extracts of publicly accessible documents, prepared by the task designer on 2026-10-30 (UTC).

(b) judge whether the assertion \"In September 2026, the unemployment rate among core-aged women (aged 25 to 54) rose 0.3 percentage points to 5.3%, and the unemployment rate among core-aged men also rose, by 0.2 percentage points, to 5.8%\" is supported by the release.\n\n## Data and exclusions\n- `data/sources/statcan-daily-lfs-2026-09.txt` (164 lines; SHA-256 7ea5fec5…d0bb, same as in `data/README.md`) and `data/README.md` (9 lines) were read (`n_input_rows`). Nothing was excluded (`out/exclusions.csv`: 164 lines kept, 0 removed). The audit is in `out/state/data_audit.md`.\n- Problems found in the inputs (`data_issues`): (1) the README and the extract header mention RESEA/London tables and regression tables that are not in this extract, which looks like boilerplate copied from other bundles; (2) lines 53–60 (layoff, job-finding and participation paragraphs and the population-aging text box) have no `##` heading of their own, and the list of SDG goals is not reproduced. Neither problem touches the requested figures or the sentences behind the assertion.\n\n## Method\n`out/analysis.py` reads the extract line by line and tracks the current `## ` heading. It finds national statements with regular expressions: \"The unemployment rate <verb> x percentage points to y%\" and, at the start of a line, \"Employment / In September, employment <verb> by N\". It checks that all matches agree, then takes the value printed under \"Highlights\" as the primary locator. \"declined\" is converted to a negative sign. The printed sentences about core-aged women and men are matched, and each of the six asserted elements is compared with them: direction, size of the change and level, for each gender. The verdict follows the task's definition: if any one element is contradicted, the assertion is `not_supported`. The script prints every matched source line. No randomness is used (`random_seed` = null). A manual grep of the same lines served as the baseline (P2) and agrees with the script.\n\n## Results\n- National unemployment rate, September 2026: **6.5%** (`unemployment_rate_sep2026`). Locator: `statcan-daily-lfs-2026-09 | section \"Highlights\"` (`locators`). The same figure appears under section \"Unemployment rate increases to 6.5%\" (`corroborating_locators`).\n- Monthly employment change, September 2026: **−68,000 persons** (`employment_change_sep2026_persons`; printed as \"Employment declined by 68,000 (-0.3%)\"). Locator: `statcan-daily-lfs-2026-09 | section \"Highlights\"` (`locators`). The same figure appears under section \"Employment falls for second consecutive month\" (`corroborating_locators`).\n- Assertion verdict: **not_supported** (`assertion_verdict`). Locator: `statcan-daily-lfs-2026-09 | section \"Unemployment rate up for core-aged women\"` (`assertion_locator`). The part about women matches the release: \"the unemployment rate rose 0.3 percentage points to 5.3%\". But the release says \"the unemployment rate for core-aged men fell 0.2 percentage points to 5.8%\". The size (0.2 points) and the level (5.8%) match the assertion; the direction (\"fell\", not \"rose\") contradicts it (`assertion_reason`, `assertion_elements`).\n- Items assessed: 3, namely two figures and one assertion (`n_analysed`). Feasibility: complete (`feasibility`).\n\n## Uncertainty\nThese are values as printed, so no statistical uncertainty is estimated. The release notes that it discusses differences significant at the 68% level, but it gives no standard errors in the text. The extraction itself is not in doubt: each headline figure is printed identically in two sections (`n_matches_unemployment_rate` = 2, `n_matches_employment_change` = 2), and the verdict rests on one unambiguous verb (\"fell\").\n\n## Limitations and open issues\n- Choice of locator: both figures are stated in \"Highlights\" and again in a dedicated section. I report \"Highlights\" as the primary locator and list the dedicated sections as corroboration. Both are valid places in the release.\n- Possible source of the error in the assertion: the release reports that the rate for people aged 55 and older \"rose 0.2 percentage points to 5.3%\" (same section). The assertion's \"rose by 0.2\" may come from mixing up that group with core-aged men. This is an interpretation only, and the verdict does not depend on it.\n- The flattened text puts the paragraph about men under the heading \"Unemployment rate up for core-aged women\". That is where the sentence actually sits in the release, so the locator uses that heading.\n- The data tables (Tables 1–12) are not reproduced, so the printed figures could not be cross-checked against tabulated values.\nstep,rule,n_before,n_after,n_removed,rationale\n1,\"none: all 164 lines of the extract retained and searched\",164,164,0,\"text extraction task; no filtering needed\"\n\"\"\"F4-dev-01: extract headline LFS Sept 2026 figures and assess an assertion.\nReads only data/; writes out/results.json deterministically.

The unemployment rate increased 0.1 percentage points to 6.5%.\n 18\tThe employment decline was concentrated among youth aged 15 to 24 (-48,000; -1.8%) as well as women aged 25 to 54 (-28,000; -0.4%).\n 19\tThere were fewer people working in educational services (-35,000; -2.2%), health care and social assistance (-23,000; -0.8%) as well as manufacturing (-13,000; -0.7%). There were more people working in 'other services' (+17,000; +2.1%), which includes repair and maintenance as well as personal or household services.\n 20\tEmployment decreased in Quebec (-49,000; -1.1%), British Columbia (-20,000; -0.7%) and Manitoba (-4,400; -0.6%). It increased in Alberta (+23,000; +0.9%), Newfoundland and Labrador (+1,800; +0.7%), and Prince Edward Island (+1,000; +1.0%).\n 21\tAverage hourly wages among employees rose 2.3% (+$0.86 to $37.64) on a year-over-year basis in September, following growth of 2.0% in August (not seasonally adjusted).\n 22\t\n 23\t## Employment falls for second consecutive month\n 24\tIn September, employment declined by 68,000 (-0.3%), split between full-time work (-35,000; -0.2%) and part-time work (-33,000; -0.9%). The employment decline in September follows a decrease in August (-42,000; -0.2%).\n 25\t\n 26\t## Chart 1 \n 27\t\n 28\tEmployment rate decreases in September\n 29\t\n 30\tPrior to these two consecutive monthly declines, employment had trended up from April to July (+181,000; +0.9%). On a year-over-year basis, employment was up by 95,000 (+0.5%) in September.\n 31\tThe employment rate—the proportion of the population aged 15 and older who are employed—decreased by 0.2 percentage points to 60.6% in September, marking a second consecutive monthly decrease. On a year-over-year basis, the employment rate in September was unchanged.\n 32\t\n 33\t## Infographic 1 \n 34\t\n 35\tEmployment rate by age group, September 2026\n 36\t\n 37\t## Downward trend in the number of public sector employees\n 38\tIn September, the number of public sector employees declined by 70,000 (-1.5%). This was the fourth consecutive monthly decline for the sector. On a year-over-year basis, the number of public sector employees was down by 119,000 (-2.6%), with most of the decline attributable to employment in educational services.\n 39\tThe number of private sector employees was little changed for a second consecutive month in September but it was up by 163,000 (+1.2%) compared with 12 months earlier.\n 40\tSelf-employment edged down in September (-23,000; -0.8%). This follows an upward trend from April to July. On a year-over-year basis, self-employment was up by 51,000 (+1.9%).\n 41\t\n 42\t## Unemployment rate increases to 6.5%\n 43\tThe unemployment rate rose 0.1 percentage points to 6.5% in September. Earlier in the year, it reached a recent peak of 6.9% in April, before declining to 6.4% in July and August. The unemployment rate in September was the same as it was at the start of the year (6.5% in January).\n 44\t\n 45\t## Chart 2 \n 46\t\n 47\tUnemployment rate rises to 6.5% in September\n 48\t\n 49\t## Infographic 2 \n 50\t\n 51\tUnemployment rate by age group, September 2026\n 52\t\n 53\tThe layoff rate—representing the proportion of people who were employed in August but had become unemployed in September as a result of a layoff—was 0.7%, similar to the rate observed a year earlier (0.6%) and the average during the period from 2017 to 2019 (0.6%) (not seasonally adjusted).\n 54\tThe job-finding rate was 30.6% in September, down from 32.8% 12 months earlier and below the average of 36.5% during the period from 2017 to 2019. This refers to the proportion of people who were unemployed in August and had found a job in September.\n 55\tThe labour force participation rate—the proportion of the population aged 15 and older who were employed or looking for work—fell 0.2 percentage points to 64.8% in September. This was the lowest level since December 1997 (when it was also 64.8%), excluding 2020 during the COVID-19 pandemic. On a year-over-year basis, the participation rate was down 0.4 percentage points in September 2026, largely the result of population aging (See text box: The impact of population aging on the declining participation rate).\n 56\tThe impact of population aging on the declining participation rate\n 57\tThe Canadian population is aging and is projected to continue to exert downward pressure on labour supply in the coming years (See: The labour force in Canada and its regions: Projections to 2036; The impact of aging on labour market participation rates). While older Canadians are participating in the labour market at higher rates relative to previous cohorts, there is nonetheless a drop-off in participation rates at older ages, especially for those aged 65 and older.\n 58\tIn September 2026, people aged 65 and older accounted for 23.2% of the working-age population (i.e., those aged 15 and older) in the Labour Force Survey, up from 20.5% in September 2019, prior to the COVID-19 pandemic (see Chart 3). In comparison, this share was 14.8% at the turn of the millennium.\n 59\tThe upward trend in the share of people aged 65 and older in the working-age population was briefly paused in 2023 and 2024, as sharp increases in permanent and temporary immigration offset the aging of the population. However, in 2025 and into 2026, the trend towards an aging population resumed.\n 60\tThe lower labour force participation rate observed in September 2026, relative to a year earlier and to the pre-pandemic period, can largely be attributed to population aging. Using a method that holds constant the September 2019 age composition of the population, the participation rate in September 2026 would be little changed (-0.1 percentage points) year over year and would be 0.2 percentage points higher than in September 2019 (see Chart 4).\n 61\t\n 62\t## Chart 3 \n 63\t\n 64\tProportion of people aged 65 and older in the working-age population\n 65\t\n 66\t## Chart 4 \n 67\t\n 68\tLabour force participation rate, holding the age composition constant to September 2019\n 69\t\n 70\t## Youth employment declines\n 71\tEmployment among youth aged 15 to 24 fell (-48,000; -1.8%) for a second consecutive month in September. The cumulative decline over this two-month period (-67,000; -2.4%) offset gains recorded earlier from April to July. The employment decline in September was accompanied by a decline in the number of youth in the labour force (-50,000; -1.6%), and the youth unemployment rate was little changed at 13.0%.\n 72\t\n 73\t## Unemployment rate up for core-aged women\n 74\tAmong core-aged women (25 to 54 years old), the unemployment rate rose 0.3 percentage points to 5.3% in September, as employment fell (-28,000; -0.4%) and the number of women in this age group searching for work increased (+18,000; +4.9%). Despite the monthly increase, the unemployment rate for core-aged women in September was 0.5 percentage points lower than a year earlier and 0.6 percentage points below a recent peak of 5.9% in April.\n 75\tAmong core-aged men, employment held steady in September while the number of men in this age group searching for work edged down. As a result, the unemployment rate for core-aged men fell 0.2 percentage points to 5.8% in the month. Compared with the same month last year, the unemployment rate for core-aged men was down 0.3 percentage points in September.\n 76\tThe unemployment rate among people aged 55 and older rose 0.2 percentage points to 5.3% in September, as more people in this age group looked for work. On a year-over-year basis, the unemployment rate for this group was little changed in September.\n 77\t\n 78\t## Fewer people working in educational services, health care and social assistance as well as manufacturing\n 79\tEmployment in educational services fell by 35,000 (-2.2%) in September, following seven consecutive months of little change. Compared with September 2025, employment in educational services was down by 67,000 (-4.2%). The year-over-year decrease was concentrated in Quebec (-27,000; -7.0%), Ontario (-19,000; -3.2%) and Alberta (-17,000; -9.0%).\n 80\t\n 81\t## Chart 5 \n 82\t\n 83\tEmployment change by industry, September 2026\n 84\t\n 85\tEmployment in health care and social assistance fell by 23,000 (-0.8%) in September, the first monthly decrease since December 2022. Despite the decline, employment in health care and social assistance was up by 93,000 (+3.2%) in the 12 months to September and was the largest contributor to overall employment growth over that period.\n 86\tIn September, employment also fell in manufacturing (-13,000; -0.7%), following an increase of 22,000 (+1.2%) in August. Employment in manufacturing was little changed in September compared with 12 months earlier.\n 87\tMeanwhile, employment in 'other services' increased by 17,000 (+2.1%) in September and was up by 32,000 (+4.1%) compared with September 2025. This industry includes repair and maintenance as well as personal or household services.\n 88\t\n 89\t## Employment declines in Quebec and British Columbia, increases in Alberta\n 90\tEmployment in Quebec fell by 49,000 (-1.1%) in September, following a decrease of 19,000 (-0.4%) in August. Employment in the province has trended down since the start of the year, with a cumulative decline of 130,000 (-2.8%) from January to September. The unemployment rate in Quebec was 6.0% in September, up 0.4 percentage points in the month and up 0.8 percentage points from January.\n 91\t\n 92\t## Map 1 \n 93\t\n 94\tUnemployment rate by province and territory, September 2026\n 95\t\n 96\tIn British Columbia, employment fell by 20,000 (-0.7%) in September, marking the first monthly decrease since March for the province. The employment rate in British Columbia fell 0.4 percentage points to 60.5% while the unemployment rate was little changed at 6.4%.\n 97\tEmployment in Ontario edged down (-20,000; -0.2%) in September but was up by 86,000 (+1.1%) compared with 12 months earlier. The unemployment rate in Ontario was little changed at 7.0% in September but was down 0.9 percentage points from 12 months earlier.\n 98\tOn the other hand, employment in Alberta rose by 23,000 (+0.9%) in September and was up by 76,000 (+2.9%) compared with a year earlier. The unemployment rate in the province was 6.4% in September, down both in the month (-0.4 percentage points) and on a year-over-year basis (-1.3 percentage points).\n 99\t\n 100\tTable 1\n 101\tLabour force characteristics by age group and gender^, seasonally adjusted\n 102\t\n 103\tTable 2\n 104\tEmployment by class of worker and industry, seasonally adjusted\n 105\t\n 106\tTable 3\n 107\tLabour force characteristics by province, seasonally adjusted\n 108\t\n 109\tTable 4\n 110\tLabour force characteristics by province, age group and gender^, seasonally adjusted (Newfoundland and Labrador, Prince Edward Island, Nova Scotia, and New Brunswick)\n 111\t\n 112\tTable 5\n 113\tLabour force characteristics by province, age group and gender^, seasonally adjusted (Quebec, Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia)\n 114\t\n 115\tTable 6\n 116\tEmployment by province and industry, seasonally adjusted\n 117\t\n 118\tTable 7\n 119\tLabour force characteristics by census metropolitan area, three-month moving average, seasonally adjusted\n 120\t\n 121\tTable 8\n 122\tLabour force characteristics by Montréal, Toronto and Vancouver census metropolitan areas, monthly, seasonally adjusted\n 123\t\n 124\tTable 9\n 125\tLabour force characteristics by province and economic region,^ three-month moving average ending in September 2025 and September 2026, unadjusted for seasonality\n 126\t\n 127\tTable 10\n 128\tLabour force characteristics by territory, three-month moving average, seasonally adjusted\n 129\t\n 130\tTable 11\n 131\tAverage usual hours and wages of employees by selected characteristics, unadjusted for seasonality\n 132\t\n 133\tTable 12\n 134\tRegional unemployment rates used by the Employment Insurance program,^ three-month moving average, seasonally adjusted\n 135\t\n 136\t## Sustainable Development Goals\n 137\tOn January 1, 2016, the world officially began implementation of the 2030 Agenda for Sustainable Development—the United Nations' transformative plan of action that addresses urgent global challenges over the next 15 years. The plan is based on 17 specific sustainable development goals.\n 138\tThe Labour Force Survey is an example of how Statistics Canada supports the reporting on the Global Goals for Sustainable Development. This release will be used in helping to measure the following goals:\n 139\t\n 140\t### Note to readers\n 141\t\n 142\tThe Labour Force Survey (LFS) estimates for September reflect labour market conditions during the reference week of September 13 to 19, 2026.\n 143\tThe sample size of the LFS is approximately 65,000 households, representing over 100,000 respondents each month. For more information, see the Guide to the Labour Force Survey.\n 144\tThis analysis focuses on differences between estimates that are statistically significant at the 68% confidence level. Monthly estimates may show more sampling variability than trends observed over longer periods. For more information, see \"Interpreting Monthly Changes in Employment from the Labour Force Survey.\"\n 145\tLFS estimates at the Canada level do not include the territories.\n 146\tThe LFS estimates are the first in a series of labour market indicators released by Statistics Canada, which includes indicators from programs such as the Survey of Employment, Payrolls and Hours (SEPH); Employment Insurance Statistics; and the Job Vacancy and Wage Survey. For more information on the conceptual differences between employment measures from the LFS and those from the SEPH, refer to section 8 of the Guide to the Labour Force Survey.\n 147\tThe employment rate is the number of employed people as a percentage of the population aged 15 years and older. The rate for a particular group (for example, youth aged 15 to 24 years) is the number employed in that group as a percentage of the population for that group.\n 148\tThe unemployment rate is the number of unemployed people as a percentage of the labour force (employed and unemployed).\n 149\tThe participation rate is the number of employed and unemployed people as a percentage of the population aged 15 years and older.\n 150\tFull-time employment consists of persons who usually work 30 hours or more per week at their main or only job.\n 151\tPart-time employment consists of persons who usually work less than 30 hours per week at their main or only job.\n 152\tTotal hours worked refers to the number of hours actually worked at the main job by the respondent during the reference week, including paid and unpaid hours. These hours reflect temporary decreases or increases in work hours (for example, hours lost due to illness, vacation, holidays or weather; or more hours worked due to overtime).\n 153\tThis release refers to the gender of a person. The category \"men\" includes men, as well as some non-binary persons. The category \"women\" includes women, as well as some non-binary persons. Given that the non-binary population is small, data aggregation to a two-category gender variable is necessary to protect the confidentiality of responses provided.\n 154\t\n 155\t### Seasonal adjustment\n 156\tUnless otherwise stated, estimates presented in this release are seasonally adjusted, which facilitates comparisons by removing the effects of typical seasonal variations. For more information on seasonal adjustment, see Seasonally adjusted data: Concepts and interpretation.\n 157\t\n 158\t### Population totals in the Labour Force Survey\n 159\tThe LFS target population includes all persons aged 15 years and older whose usual place of residence is in Canada, with some exceptions (those living on reserves, full-time members of the regular Armed Forces and persons living in institutions). The target population includes temporary residents—that is, those with a valid work or study permit, their families, and refugee claimants—as well as permanent residents (landed immigrants) and the Canadian-born.\n 160\tInformation gathered from LFS respondents is weighted to represent the survey target population using population calibration totals. These totals are updated each month, using the most recently available information on population changes derived from Canada's official population estimates, with minor adjustments being made to reflect the LFS target population.\n 161\tWhile the LFS population totals are generally aligned with official demographic estimates, the official estimates should be considered the official measure of population change in Canada. More information on how population totals in the LFS are calculated can be found in the article \"Interpreting population totals from the Labour Force Survey.\"\n 162\t\n 163\t### Next release\n 164\tThe next release of the LFS will be on November 6, 2026. October 2026 data will reflect labour market conditions during the week of October 11 to 17.\n# Data provenance — F4-dev-01\n\nAll files under `data/sources/` are plain-text extracts of publicly accessible documents, prepared by the task designer on 2026-10-30 (UTC).
