The census median was $1,510,000 in 2021, against $695,000 for Ontario’s towns. There is no public record of sale prices in Ontario, which leaves the census value as the guide for Unionville. The 2024 property assessment puts the median residential property at $787,000. MPAC hasn’t reassessed since its 1 January 2016 values, which is why the figure sits well under the census value; it compares only within Ontario. Figures for assessed values, values by property type and building permits are published for the city of Markham as a whole, not for Unionville alone.
What Unionville’s homes are worth, two ways
Every figure here is compared within the province, against Ontario’s towns, since each province assesses on its own terms. An owner’s figure, not a sale: the census of May 2021 asked what each home would fetch.
