Disagree about your Assessment?
If you do not agree with your assessment value you can:
1. Contact MPAC directly at 1-866-296-2722
2. Ask MPAC to review your assessment through a Request of Reconsideration (RfR). If you feel your assessed value or property classification is not correct, MPAC will review it free of charge. The deadline to file your RfR is printed on your property assessment notice.
There are two ways to request a reconsideration:
- The preferred method is to submit a RfR form. Forms are available at MPAC, or call them toll-free at 1 866 296-MPAC (6722) to request a form.
- Write a letter requesting a reconsideration. In your letter, please include the 19-digit roll number on your Notice; your full name, address and phone number; and the reasons why you feel your assessment is not correct, including any information you have to support your claim.
3. File an Appeal with the Assessment Review Board (ARB). You may choose to file an appeal with the ARB, an independent tribunal of the Ontario Ministry of the Attorney General.
