The purpose of filing a Request for Reconsideration
The Request for Reconsideration gives you an opportunity to have us review your assessment in detail, free of charge, to determine if it is accurate. During the review, you may be able to provide new information or correct inaccurate information that has played a part in the assessment. In this way, concerns may be resolved without the need for an appeal.
You may also file an appeal of MPAC’s assessment with the Assessment Review Board (ARB). The Assessment Review Board is an independent tribunal (decision-making body) of the Ontario Ministry of the Attorney General.
However, if your property, or a portion of it, is classified as residential, farm or managed forests, you must first file a Request for Reconsideration with MPAC before you are eligible to appeal to the Assessment Review Board.
Who can file a Request for Reconsideration
You can file a Request for Reconsideration if you:
- are the property owner
- received a Property Assessment Notice
- are the property owner’s representative
For more information, contact us.
Reasons for filing a Request for Reconsideration
Some examples of reasons to file a Request for Reconsideration include:
- You believe that your assessed value is too high or too low.
- The property data on your Notice of Assessment or on MPAC AboutMyProperty is incorrect. For example, you may want to update the information we have on file on the size of your building or the area of your land.
- You believe your property classification should be different.
- You have more than one type of property (or "property classification") listed on your Notice of Assessment, and the portions of assessed value for each class are incorrect. For example, your property may include both commercial and tax-exempt portions.
- You received a Property Assessment Change Notice that you believe is incorrect.

Your role in the process
As part of the Request for Reconsideration process, you'll need to gather evidence to support your Request for Reconsideration. This may include things like:
- photos that demonstrate the differences between our records and the property in its current condition
- sale information on your property or comparable properties
- the assessed value for comparable properties, which you can find in MPAC AboutMyProperty
- recent appraisals
- zoning information
- estimates for significant repairs (e.g. repairs for cracked and leaking foundation walls, water damage due to flooding, termite damage, sagging roof line, etc.)
Step-by-step instructions
- If you are considering submitting a Request for Reconsideration, ask yourself, “Could I have sold my property on January 1, 2016 for the assessed value stated on my Notice?”
- If the answer is yes, no further action is required. File your notice for future reference.
- If the answer is no, log in to MPAC AboutMyProperty to learn more about how your property was assessed, see the information we have on file, and compare it to other properties in your area.
- If you still disagree, you can file a Request for Reconsideration online through MPAC AboutMyProperty or by mail.
- We will send you a confirmation saying we have received your Request for Reconsideration. Once our review is complete, we will notify you of the result in writing usually within 180 days – up to 60 additional days if we need more time.
- If we find that we should make an adjustment, we will apply any changes to your property valuation and send you a new Property Assessment Notice or Property Assessment Change Notice.
- We will also ask you to sign a Minutes of Settlement that we will use to notify your municipality about the change, so that they can make a property tax adjustment if necessary.
6. If you still disagree with your assessment, you can submit an appeal to the Assessment Review Board (ARB), an independent decision-making body of the Ontario Ministry of the Attorney General.
- You have 90 days from the date that we issue the results of your Request for Reconsideration to submit an appeal to the Assessment Review Board. Learn more about how the appeals process works, and visit the ARB's website for forms, fees and more information about filing an appeal.
