What the numbers mean
- Owners valued the median home at $1.12M in the 2021 census. Indexed to September 2026 prices with the Greater Toronto MLS® Home Price Index (-11% since then), that is about $998K, close to the Toronto-area suburbs median of $917K. It is an estimate: the index tracks the whole region, not this neighbourhood.
- 24% of households rent, well below the 34% city-wide. Most people here own and stay a while.
- 24% are 65 or older, versus 16% city-wide, a sign of long-time residents and a settled pace.

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.
