I wanted to share an important reminder regarding your property taxes for 2026.
If you believe your home’s assessed value is too high or inaccurate, you have the right to challenge it through the Municipal Property Assessment Corporation (MPAC).
Key Deadline:
March 31, 2026
By this date, homeowners must file a Request for Reconsideration (RfR) with MPAC. This is a free process and is the required first step for residential properties before any formal appeal.
When should you consider this?
You may want to review your assessment if:
- Your home seems assessed higher than similar properties in your area
- There are errors in your property details (size, features, etc.)
- The assessed value doesn’t reflect your property’s condition
What happens next?
- MPAC will review your request and respond
- If you disagree with their decision, you can escalate it to the Assessment Review Board (ARB)
Keep in mind that Ontario property assessments are still based on market values from January 1, 2016.
