What the numbers mean

  • Owners valued the median home at $954K in the 2021 census. Indexed to September 2026 prices with the Greater Toronto MLS® Home Price Index (-11% since then), that is about $851K, close to the Toronto-area suburbs median of $917K. It is an estimate: the index tracks the whole region, not this neighbourhood.
  • 30% of households rent, below the 34% city-wide.
  • 21% are 65 or older, versus 16% city-wide, a sign of long-time residents and a settled pace.
  • Housing is a mix: 48% apartments, with the rest townhouses, duplexes and houses.

How it's changing

These municipalities don't publish building permits by neighbourhood, so we can't chart construction here yet.

Safety

Neighbourhood-level crime figures aren't available for Markham. Policing there is by a regional police service, and none publishes neighbourhood crime counts we can compare with Toronto's. Check Statistics Canada's crime tables for municipality-wide trends, and the local police website for crime maps. Why this is missing.
