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:
- File a Request for Reconsideration (RFR) with the Municipal Property Assessment Corporation (MPAC)
- Receive the RFR decision BEFORE filing an appeal with the ARB.
- 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 – 2018-2020 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
If you do not file a 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, please make sure you have your Property Assessment Notice and/or your RFR decision from MPAC.

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.
If your property is in a municipality outside of Toronto, you would file a:
Municipal Act Appeal (filed under various sections of the Municipal Act, 2001.)
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.
If the appeal remains open on March 31st, then that appeal will be deemed for the subsequent tax year. Deeming only occurs within the cycle. For example:
- 2017 s.40 appeal will deem into a 2018 s.40 appeal
- 2020 s.40 appeal will not deem into a 2021 s.40 appeal
