Overview

Property assessments in Ontario are prepared by the Municipal Property Assessment Corporation (MPAC). If you believe your assessment is incorrect, you can ask MPAC to review it or pursue a formal appeal to the provincial assessment tribunal. Early review often resolves simple errors; formal appeals require forms, evidence, and adherence to deadlines described on official pages MPAC - Appeals[1] and the Assessment Review Board guidance Tribunals Ontario - Assessment Review Board[3].

Check your assessment notice date immediately to note deadlines.

How to prepare

  • Gather your assessment notice, property record, recent sale comparables, income/expense statements (if rental), and building permits.
  • Compare the MPAC property details against your municipal property tax roll and building records; report errors to MPAC first.
  • Take dated photos and prepare a concise cover letter summarizing the discrepancy and requested change.

Steps to Request Review or Appeal

  1. Request a review from MPAC (Request for Reconsideration or RFR) outlining the error and attaching evidence; see MPAC guidance MPAC - Appeals[1].
  2. If MPAC denies or does not resolve your concern, file a formal appeal with the Assessment Review Board following the tribunal's filing rules Tribunals Ontario - Assessment Review Board[3].
  3. Contact City of Kitchener Revenue or By-law Enforcement for information about how municipal records may affect your submission City of Kitchener - Property Taxes[2].
