Property Assessments are determined by the Municipal Property Assessment Corporation (MPAC), which administers a uniform, province-wide property assessment system based on current value assessment in accordance with the provisions of the Assessment Act. It provides municipalities with a range of services, including the preparation of annual assessment rolls used by municipalities to calculate property taxes.

 2020 Assessment Update

Updated property values are no longer coming this year

The Ontario government has announced that the 2020 Assessment Update has been postponed. They have indicated that property assessments for the 2021 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 2021 property tax year will be the same as the 2020 tax year, unless there have been changes to your property.

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