The 2021 census put the median home at $1,000,000, with an average of $1,110,325. Statistics Canada doesn’t publish sales in Ontario, so nothing here says what Upper Cornell’s homes actually sold for. For 2024, the median assessed value of a residential property is $787,000. Ontario’s assessments are still on MPAC’s values of 1 January 2016, far below today’s prices, so they compare only with other Ontario towns. Upper Cornell shares its assessed values, values by property type and building permits numbers with the rest of the city of Markham.

Two sources, each set against Ontario’s towns only: provinces measure value differently, so they don’t line up across borders. Keep in mind these are owners’ estimates from the 2021 census, not recorded sales.
