About our data
About our data
Our data comes from periodic captures of active listings — what was on the market when we looked, not a complete history. Sold and past listings aren't available to us.
Each listing credits the agent(s) named on it in the listing data, applied the same way for every agent.
We cover a defined and growing set of Canadian markets; activity outside them isn't reflected.
Rankings are our editorial opinion, applying stated criteria uniformly. We don't accept payment for placement and we correct verified data errors promptly —

▸How We Pick Our Top Realtors
— our criteria, data sources and limits
We rank agents on their track record in this community — the listing activity we've tracked here over time — with extra weight for agents who are active right now, hold a strong Google review record, and work from an office close to the areas they serve. Recent activity is time-weighted: a listing that sells in a normal timeframe keeps its full value, while one that sits unsold for months gradually counts for less. Our data comes from periodic captures of active listings — it reflects what was on the market when we looked, not a complete history of every listing an agent has ever had. Our index covers a defined and growing set of Canadian markets, so rankings reflect activity within the coverage we've chosen rather than everything an agent may do elsewhere. We periodically update our information and last reviewed Blackwell, Sarnia on October 6 2026.
Not every active agent is ranked: the index covers agents with recent
activity in this market's typical price range. An agent whose only
listings here are leases, fall outside that range, or are too old to
score counts toward the market totals but doesn't appear in the rankings.
Rankings are our editorial opinion, applying the criteria above to public
listing and review data. We don't accept payment for placement, and we
correct verified data errors promptly —
