Municipal Property Assessment Corporation

Site: Trenton Assessment Field Office

Description (Service) COVID19: 
Regular Service 
Responsible for accurately assessing and classifying all properties in Ontario in compliance with the Assessment Act and regulations set by the Government of Ontario. MPAC provides municipalities with a range of services, including the preparation of annual assessment rolls used by municipalities to calculate property taxes.  
  • As part of the Ontario Government’s Budget on March 24 2021, the Minister of Finance announced the Province’s decision to postpone a province-wide property assessment update due to the pandemic.  
  • Property assessments for the 2022 property tax year will continue to be based on January 1, 2016 current values. This means your property assessment remains the same as it was for the 2021 tax year, unless there have been changes to your property, for example:
    1. A change to your property including an addition, new construction, or renovation.  
    2. A structure on your property was assessed for the first time  
    3. A change to your property’s classification  
    4. A property no longer qualifies as farmland, conservation land or managed forests  
    5. All or part of your property no longer qualifies to be tax exempt
  • MPAC will continue to update property information to enable the People of Ontario to access impartial property data for smart business planning and strategy development.
    • 2016 Notice reflects the assessed value and classification of your property as of January 1, 2016.
  • Property owners can visit to learn more about how their property was assessed, see the information on file, and compare it to others in their neighbourhood.  
  • MPAC maintains owner and occupancy information and facilitates municipal enumeration activities. Ontario’s municipal and school board elections took place on Oct 22, 2018. MPAC has the legislative responsibility of producing the Preliminary List of Electors (PLE) for municipal and school board elections. The Preliminary List of Electors is not the Voters' List. Each municipality is responsible for finalizing their Voters’ List.  
  • It is the responsibility of every elector to make sure their information is up-to-date and accurately reflected for electoral purposes. By logging into, eligible electors can:
    • confirm or update their electoral information;  
    • add an elector name to an address; and,  
    • change school support.
