The Municipal Property Assessment Corporation (MPAC) is responsible for the calculation of assessed values and classification of each of the over four million properties in Ontario. This data is used by municipalities and the province to calculate property and education taxes.
To find out more visit the Municipal Property Assessment Corporation website.
Please note that as part of Ontario's Action Plan: Responding to COVID-19, the 2020 Assessment Update which was planned this year to reassess properties for the 2021-2024 years has been postponed. Assessments for the 2021 taxation year will continue to be based on the same valuation date that was in effect for the 2020 taxation years. MPAC will continue to update assessment to reflect new construction.
Visit the MPAC website for further information on this matter.
