Common questions about the Ontario property assessment appeal process
The deadline for filing a Request for Reconsideration with MPAC is March 31st of the year following the assessment. Missing this deadline means you cannot appeal your current assessment.
Filing a Request for Reconsideration with MPAC is free. However, if you proceed to the Assessment Review Board, there may be filing fees. Professional assistance costs vary based on property complexity.
Strong appeals typically include comparable sales data, professional appraisals, photos of property conditions, repair estimates for defects, and documentation of any assessment errors.
MPAC has 90 days to respond to a Request for Reconsideration. If you're not satisfied, you have 120 days to appeal to the Assessment Review Board, where the process can take 6-18 months.
While you can file an appeal yourself, complex properties or significant assessment discrepancies often benefit from professional assistance. Consider your property value, potential savings, and complexity of the case.
