It draws on the same City open data the municipality publishes, but does not carry the City's certification or legal standing. For an authoritative record — or any legally-binding transaction — order the City of Toronto's official Property Information Report. Not legal, title, or professional advice. Records reflect the most recent data we have ingested and may lag the City's live system.
