Tax Assessment

Your property assessment is determined by the Municipal Property Assessment Corporation (MPAC). To establish your property's assessed value, MPAC analyzes sales of comparable properties in your area. This method, called Current Value Assessment (CVA), is used by most assessment jurisdictions in North America. In addition, MPAC looks at all of the key features that affect market value. When assessing residential properties 200 different factors are considered.

What if I don't agree with MPAC's assessed value?

Property owners in the residential, farm, and managed forest property classes who have concerns with the current value assessment or classification of their property should contact the Municipal Property Assessment Corporation (MPAC) by first submitting a Request for Reconsideration (RFR) form. MPAC will conduct a review. This service is free of charge. Deadline to file is printed on your Property Assessment Notice.

Property owners in all other classes can choose to file either a RFR (Non-Residential) or proceed directly with an Assessment Review Board Appeal (ARB).
