What do I do with my Property Assessment Change Notice?

Your Property Assessment Change Notice has important information for you as a property owner. Please review it and file it away for your records. No action is required unless you have questions about your assessment.

Questions about your assessment

Visit AboutMyProperty to learn more about how your property was assessed, see the information we have on file, and compare it to others in your neighbourhood. Look for your Roll Number and Access Key on your Property Assessment Change Notice to register.

If you still disagree with MPAC’s assessment or classification of your property, you can choose to either file a Request for Reconsideration (RfR) with MPAC or file an appeal directly with the Assessment Review Board (ARB).

If your property, or a portion of it, is classified as residential, farm or managed forest, you must first file an RfR with before you are eligible to appeal to the ARB.

Property owners have 120 days from the issue date on their Property Assessment Change Notice (PACN) to file an RfR. The issue date and your unique RfR deadline are included on your PACN.

Due to the emergency declared by the Province of Ontario, under the Emergency Management and Civil Protection Act and its regulations, your deadline to file an RfR may have been extended. Please log in to AboutMyProperty to learn your new deadline for submitting an RfR or contact us.

The fastest way to start the review of your property’s assessment is to file a RfR on AboutMyProperty. This web-based tool allows you to attach pictures and reports to accompany your RfR and check the status of your request. You may also send us your completed RfR form by email or mail.
