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. Learn about the process for filing tax applications.

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 – 2026 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
  • 2026 – March 31, 2026

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.

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.

Eligible conservation land properties may be assigned to the Conservation Land exempt tax class and that portion of the property will be 100 per cent property tax exempt. If there is an issue with your eligibility, you must file an RFR with the Program Administrator first.

3. Apply for property tax relief because of sickness or extreme poverty

Learn how to ask for your property taxes to be reduced, canceled or refunded if you can’t pay because of sickness or extreme poverty.

On This Page


About

You may qualify for property tax relief if you cannot pay your property taxes because of sickness or extreme poverty.

Before you file with the ARB

  1. Contact your municipality. Depending on where you live, you will either submit your sickness or extreme poverty application to your municipality or the ARB. Contact your municipality to find out.
  2. Use Statistics Canada’s Market Basket Measure (MBM) Thresholds to estimate whether you meet the definition of extreme poverty. When a family’s disposable income is 25% below the threshold, they meet the definition of extreme poverty. Find out your threshold by selecting your household size and where you live.

    Your net income is not the only factor the ARB considers when deciding whether to reduce, cancel or refund your property taxes. The ARB also takes your assets (what you own) into account.

  3. Gather documents that show your income, assets and living expenses. The ARB will use this financial information to decide your application or appeal.

Apply or appeal?

Apply to the ARB if your municipality has authorized the ARB to receive applications on its behalf.

Appeal to the ARB if you applied to the municipality, and:

  1. you disagree with its decision, or
  2. the municipality has not made a decision by September 30 of the year after you applied.

Deadlines

Stage 1: Deadline to apply

The deadline to apply for property tax relief is the last day of February in the year after you couldn’t pay your taxes. For example, if you couldn’t pay your taxes in 2026, you would have until February 28, 2027 to apply. The deadline is the same whether you are applying to the ARB or your municipality.

Stage 2: Deadline to appeal to the ARB

Stage 2 only applies if you first applied to your municipality.

  • If you disagree with the municipality’s decision, you have 35 days from the date of the decision to appeal the decision to the ARB.
  • If your municipality has not made a decision by September 30, you can apply to the ARB to make a decision instead. In this case, the deadline to apply is October 21 in the year after you couldn’t pay your taxes.

How to file

Scenario 1: You are unable to pay property taxes and the ARB handles sickness or extreme poverty applications for your municipality.

If your property is in the City of Toronto, there are two ways to file:

  1. Visit the City of Toronto’s Property Tax Appeal: Sickness or Extreme Poverty webpage for instructions, or
  2. e-File by selecting “City of Toronto Act” and then “s. 323 (1)(e) Unable to pay taxes due to sickness or extreme poverty.”

If your property is elsewhere in Ontario, there are two ways to file:

  1. Fill out the form: Municipal Act Application/Appeal – Sickness or Extreme Poverty and mail or email it to the ARB, or
  2. ARB e-File by selecting “Municipal Act” and then “s.357 (1)(d1) Unable to pay taxes due to sickness or extreme poverty.”

Scenario 2: You are appealing your municipality’s decision about your sickness or extreme poverty application.

  1. Use the form: Municipal Act Application/Appeal – Sickness or Extreme Poverty
  2. Mail or email it to the ARB

Note: If the ARB made the original decision, it cannot be appealed. You can ask the ARB to review a decision within 30 days after it is issued. A review is not a chance to make the same arguments as in your original appeal. Instead, the ARB review process looks for specific, serious mistakes.

Scenario 3: Your municipal council failed to make a decision on your application for relief from paying property taxes due to sickness or extreme poverty.

  1. Use the form: Municipal Act Application/Appeal – Sickness or Extreme Poverty
  2. Mail or email it to the ARB

e-File

e-Filing an application takes about five minutes. You must have an email to use the service. Print or save a copy of the application and acknowledgement for your records.

After filing

After the ARB receives your appeal or application, the ARB will send you:

  2. The Financial Information Form

    The form asks for details of your income, assets and living expenses. You will have 90 days to complete the form and send it to the ARB.

    Timelines: The municipality will have 10 days to respond to your form. You will have another 10 days to submit your final reply. For more information, read the Financial Information Form Instructions

  3. The date of your written hearing

    In a written hearing, the adjudicator reviews evidence and arguments that were submitted in writing. There is no teleconference, videoconference or in-person meeting.

    Timelines: The ARB can only schedule a hearing after the income tax filing deadline has passed for the year under appeal. After the notice of hearing is sent, the hearing will be scheduled no sooner than 120 calendar days from that date. You will usually get a decision about your application or appeal within 60 days of the hearing date.
