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 Ontario Government’s March 2021 budget was the announcement that the Province would again postpone a province-wide property assessment update. All property assessments for the 2022 taxation year will remain at the value they were assessed at for the 2020 and 2021 taxation years unless there has been changes made to the property such as new construction.
Visit the MPAC website for further information on this matter.
