Use e-Services to file appeals and check appeal status at the ARB.


Assessment Appeals (under sections 32, 33, 34 or 40 of the Assessment Act)

Your Property Assessment Notice from the Municipal Property Assessment Corporation (MPAC) may be for your annual assessment, a supplementary or omitted assessment (assessment change), or a correction of factual error assessment (amended assessment).

If you disagree with your Property Assessment Notice from the MPAC, you can file an assessment appeal. If you are disputing your tax bill, you can file a tax application.

If your property or a portion of it is classified as residential, farm, managed forest or conservation land you MUST:

  1. File a Request for Reconsideration (RFR) with the MPAC.
  2. Receive the RFR decision BEFORE filing an appeal with the Assessment Review Board (ARB).
  3. File your appeal before the deadline, which is 90 days from the mailing date on your RFR decision.

For all other property types, you may choose to file an RFR with the MPAC or file an appeal with the ARB.

Important Notice – 2018 – 2024 Filing Deadlines: For any property that does not classify or have a portion classified as residential, farm, managed forest or conservation land and does not require an RFR as a precondition to an appeal, the filing deadlines are as follows:

  • 2018 – April 3, 2018
  • 2019 – April 1, 2019
  • 2020 – March 31, 2020
  • 2021 – March 31, 2021
  • 2022 – March 31, 2022
  • 2023 – March 31, 2023
  • 2024 – April 2, 2024
  • 2025 – March 31, 2025

If you do not file an RFR, your deadline to file directly with the ARB is March 31 for annual assessment appeals or 120 days from the notice date for other types of assessments.

Before filing your appeal, make sure you have your Property Assessment Notice and/or your RFR decision from the MPAC.

Request for Reconsideration

Your Property Assessment Notice from the MPAC tells you the assessed value and classification of your property. If you believe the value or classification is wrong, you may file an RFR with the MPAC. For information about their process, please contact the MPAC at 1-866-296-6722.

Assessment appeals for residential, farm, managed forest or conservation land properties can only be filed with the ARB if:

  1. an RFR has been filed with the MPAC and
  2. an RFR decision has been received

Your deadline to file an appeal with the ARB is no more than 90 days from the mailing date on the RFR decision.

Farm, Managed Forest and Conservation Land Properties

Properties that are classified as farm, managed forest or conservation lands may be eligible for special tax programs. These programs are not administered by the MPAC. For issues with eligibility, you must file an RFR with the Program Administrator. After you receive an RFR decision from the Program Administrator, you may appeal that decision to the ARB.

Farm Properties

Eligible farmlands may be classed in the Farm Property Class and taxed at 25 per cent of the municipal residential rate. If there is an issue with your eligibility, you must file an RFR with Agricorp first.
