\item \textit{Notes:} Floor area is unavailable for most multiplex listings and is excluded from that segment; lot area is available for condominiums (lot share of the building) and is retained. Gatineau is the omitted regional category in every segment. The amenity indicators are highway, hospital, park, school, transit and golf course; the garage indicator is counted with the structural variables and is undefined for land.
