Property Assessment

Property Assessments are determined by the Municipal Property Assessment Corporation (MPAC). MPAC administers a uniform, province-wide property assessment system. The system is based on current value assessment in accordance with the provisions of the Assessment Act. MPAC provides municipalities with a range of services, including property assessment values. Municipalities use these values to calculate property taxes.

Assessment update

The Ontario government has announced that the 2020 Assessment Update has been postponed. Property assessments for the 2023 property tax year will continue to be based on the fully phased-in January 1, 2016 current values. This means your property assessment for the 2023 property tax year will be the same as the 2020 tax year. The assessment will change if there have been changes to your property.

In 2016, MPAC mailed a Property Assessment Notice to every property owner in the province. MPAC assessed more than five million properties in Ontario. Your 2016 Notice reflects the assessed value and classification of your property as of January 1, 2016. This information will be used as the basis for calculating your 2021 property taxes.
