Going by owners’ own estimates in 2021, the typical home is worth $950,000, the average one $1,202,000. No open sale prices are published in Ontario, so for Thornbury the census value is the measure. The 2024 property assessment puts the median residential property at $428,000. 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.
Thornbury’s homes, by two sources
Each source sits beside its own median for Ontario’s towns; none compares across provinces, which value homes in their own ways. The census figure is the owner’s own reckoning of value in May 2021; actual sale prices may differ.
