Overview

Property assessments in Montréal determine the assessed value used for municipal taxation. Appeals typically begin with an informal review by the city evaluation service and may progress to a formal tribunal or court depending on the instrument that governs assessments. Time limits, required evidence and the exact appeal body vary by situation and by the instrument referenced on your assessment notice.

Penalties & Enforcement

Appealing an assessment is an administrative and civil process; there are generally no criminal penalties for filing an appeal. Specific monetary penalties, escalation amounts, or fines for incorrect appeals are not specified on the cited page.[1]

  • Time limits - municipality often states a deadline on the assessment notice; if not listed, check the evaluation service contact for the borough.
  • Enforcer - Service de l'évaluation foncière or the borough evaluation office handles reviews and intake.
