The Canadian Real Estate Association’s Home Price Index (HPI) tracks benchmark home values across Ontario, including the London & St. Thomas area. Unlike average sale prices, the HPI measures changes in the value of “typical” homes, giving a clearer picture of how the market is really moving. This tool is useful for homeowners, buyers, and lenders who want to see long-term trends and compare local price movements to the broader Ontario market.
