How to appeal your property assessment in Quebec

In Quebec, your municipality keeps a three-year assessment roll; Montréal's 2026–2028 roll values homes as of July 1, 2024. To challenge yours, file a request for review with the assessor before May 1 of the roll's first year (May 1, 2026 in Montréal; $90 for homes assessed at $500,000 or less). If the reply doesn't satisfy you, appeal to the TAQ within 60 days.

  • Lenders don't use your assessment for a refinance; for borrowing, see the equity calculator.

Evidence wins appeals: sales of similar homes near the valuation date, similar homes' assessments, and corrections to the facts on your notice.
