Ontario has no substantially-similar private-sector privacy law → PIPEDA applies in full to MLS personal info (only BC, AB, QC have substantially-similar laws)
Created 2026-06-21
Summary
Claim. Ontario has no substantially-similar private-sector privacy law, so PIPEDA applies in full to Ontario real estate. Only BC, Alberta, and Quebec have substantially-similar laws.
Source. priv.gc.ca (Office of the Privacy Commissioner), accessed 2026-06-21.
Confidence. Verified.
Caveats. Quebec's Law 25 has significantly more aggressive enforcement than PIPEDA; do not extrapolate enforcement intensity from Quebec to Ontario.
Implication / use. Anchors Rule: Ontario has NO substantially-similar private-sector privacy law — PIPEDA applies in full. Do not extrapolate enforcement intensity from Quebec / BC / Alberta. Any Ontario MLS-data product is in PIPEDA's scope without provincial overlay.
