Municipal Property Assessment Corporation (MPAC)
Every municipality in Ontario is a member of MPAC, a non-share capital, not-for-profit corporation whose main responsibility is to provide its customers - property owners, tenants, municipalities, and government and business stakeholders - with consistent and accurate property assessments.
MPAC 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.
Who Does What?

MPAC - Request for Reconsideration
If you disagree with your property's assessed value and/or classification, you have the option to file a Request for Reconsideration and we will review it free of charge.
RfRs can be requested for various reasons, including to correct:
- an assessed value that is too high or too low;
- property data, which can include the size of a building or the area of land;
- the effective date for a supplementary or omitted assessment;
- property classification; and
- the portion of assessed value attributable to each class for those properties that have more than one property class.
What cannot be reviewed as part of the RfR process is the amount of property taxes paid to a municipality.
Before filing a Request for Reconsideration, please contact MPAC toll-free at 1 866 296-6722 or TTY 1 877 889-6722. A representative will review the information on file to ensure it is correct and up-to-date.

School Support Designation
As a property owner in Ontario, you are required to support a school board, even if you do not have children or your children are not currently attending school. By default, your school support is directed to your municipality’s English Public School Board.
In the case of a residential property occupied by tenants, they can direct the school support for that property.
Property owners, occupants, and tenants can select which school board they choose to support. Additionally, you will be able to vote in the next municipal election for trustees for the school board that you choose to support.
The Municipal Property Assessment Corporation (MPAC) is legislatively required to collect school support information and provide it in the assessment roll to every municipality and school board.
Changing your school support online
Based on your eligibility, property owners and tenants registered with MPAC can view and update the school support designation online. To learn more about eligibility requirements or change your school support designation, please visit mpac.ca/schoolsupport
