April 2026 — BrightCat Data has completed validation of 194,167 confirmed repeat-sale property pairs inside the Canadian Home Price Index dataset, the series that anchors the HPI component of the BrightCat Core product. A repeat-sale pair is a single Canadian property sold twice, linked by stable matchkey across the two transactions, with both sale prices and both transaction dates verified.
The dataset draws on twelve years of continuous weekly pipeline history, covering 5.8 million unique residential properties across all ten Canadian provinces. Of the 899,189 sold events in the BrightCat Sold product, 751,664 resolve to unique properties, and 194,167 of those properties have been sold twice or more within the observation window with both transactions captured in full.
The repeat-sale methodology is the Case-Shiller framework for real estate price indexing. The approach compares the two sale prices of the same property, holding the property itself constant, and attributes the price change to market movement rather than to differences in what is being sold. It avoids the mix effect that makes median-price indices misleading when the composition of what is selling changes over time.
For Canadian markets specifically, repeat-sale density is the binding constraint on index quality. A reliable index needs enough repeat-sale pairs in each geography and time period to produce stable readings. Without sufficient density, the index either smooths over real movement or whips on sparse data.
Within the 194,167 confirmed pairs, the distribution of sale cycles looks like this:
The dataset covers all ten Canadian provinces. Properties are linked across sale events using a matchkey based on standardized address and postal code, resistant to relist-driven MLS-number changes. Each pair is verified against the underlying sold events from the BrightCat Sold product; pairs that cannot be fully verified are excluded from the published series.
The underlying methodology is documented on the BrightCat methodology page, and the HPI dataset itself is accessible through the BrightCat Core product via Snowflake Marketplace and the MCP Connector.
The BrightCat Core HPI series is used by Canadian mortgage lenders for collateral revaluation, by insurance underwriters for risk-weighted pricing, by real estate investors for portfolio mark-to-market, and by AI-based valuation models (AVMs) as training and validation data. The series refreshes weekly alongside the rest of the BrightCat pipeline, with no pipeline for the consumer to maintain.
