The 2021 census gives $400,000 as the median value; Ontario’s towns come to $695,000. There is no public record of sale prices in Ontario, which leaves the census value as the guide for Stone Mills. Assessors valued the median residential property at $195,000 for 2024. 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.
