Assessment Review Board (Ontario)

The Assessment Review Board (ARB) in Ontario is an independent tribunal that handles disputes related to property assessments made by Municipal Property Assessment Corporation (MPAC). When property owners believe their property’s assessed value for taxation is incorrect, they can appeal to the ARB. The board reviews evidence from both the property owner and MPAC, and then makes a decision to confirm or change the assessed value. This process helps ensure fair and accurate property taxation across Ontario.
