Filing an Appeal

---

Note: Documents you submit to the Board are available to the public on request subject to limited exceptions.

You may wish to review information on the 2017-2020 assessment cycle.

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

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 Municipal Property Assessment Corporation (MPAC)
2. Receive the RFR decision BEFORE filing an appeal with the 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 either file a RFR with MPAC or file an appeal directly with the Board.

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 a 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

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

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

Your Property Assessment Notice may be for your annual assessment, or a supplementary or omitted assessment (assessment change), or a correction of factual error assessment (amended assessment). The appeal process for all types of assessment appeals is similar.

Tax Appeals

The Board also hears certain types of appeals on property taxes. These tax appeals occur after the property assessment is determined. They relate to matters that have an impact on the amount of the taxes determined for a property. There is different legislation for appealing property taxes (e.g. calculation, vacant unit, etc) depending on the location of the property in Ontario.

  Municipal Act Appeal (filed under various sections of the Municipal Act, 2001)
• If your property is in the City of Toronto, you would file a:
  City of Toronto Act Appeal (filed under various sections of the City of Toronto Act, 2006)

• Municipal Act appeals: s.357 (7), s.357 (8) & s.357 (1)(d1)

The Board will NOT waive or refund all or part of a filing fee, absent appropriate circumstances. A waiver or refund request should be directed to ARB.Registrar@ontario.ca.

After Filing an Appeal

After the Board receives an appeal, we will send you an acknowledgement letter. If the appeal was filed on time and the fee is paid, the Board will proceed to assign a commencement date and schedule of events. Please refer to our information on General and Summary Proceedings. If the parties are unable to resolve the appeal by a Mandatory Meeting Date, the Board will schedule a hearing and will mail you a notice of hearing.

• 2021 s.40 appeal will deem into a 2022 s.40 appeal
• 2022 s.40 appeal will deem into a 2023 s.40 appeal
• 2023 s.40 appeal will deem into a 2024 s.40 appeal
