That is a median of $500,000 at the 2021 census, set beside $695,000 for Ontario’s towns. Statistics Canada doesn’t publish sales in Ontario, so nothing here says what St. Marys’s homes actually sold for. The 2024 property assessment puts the median residential property at $248,000. 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.
What St. Marys’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.
