The Municipal Property Assessment Corporation (MPAC) is responsible for assessing all properties in Ontario.
MPAC provides these assessments to municipalities. The assessment is multiplied by the tax rate to determine the amount of your taxes.
As a property owner, you are required to support a school system. School support designation helps property owners and tenants identify which school board they wish to support in a school board election. School support information collected by MPAC is provided to municipalities and school boards for planning purposes. You may change the school board you support by completing and submitting the form to MPAC: Application for Direction of School Support
For information or details about your assessment, please contact MPAC at 1-866-296-6722 or visit their website at www.mpac.ca.
