Property Assessment and MPAC Information

Property assessments for the 2022, 2023 and 2024 property tax years will continue to be based on January 1, 2016 current values. This means your property assessment remains the same as it was for the 2023 tax year, unless there have been changes to your property, for example:

  • A change to your property including an addition, new construction, or renovation.
  • A structure on your property was assessed for the first time
  • A change to your property’s classification
  • A property no longer qualifies as farmland, conservation land or managed forests
  • All or part of your property no longer qualifies to be tax exempt

Municipal Property Assessment Corporation (MPAC)
As a property owner in Ontario, you’ll receive a Property Assessment Notice in the mail from MPAC every four years updating the value of your property. Due to the COVID-19 pandemic, the Ontario government has postponed the 2020 Assessment Update. They have indicated that property assessments for the 2021 property tax year will continue to be based on the fully phased-in January 1, 2016 current values. This means your property assessment for the 2021 property tax year will be the same as the 2020 tax year, unless there have been changes to your property. MPAC’s Website:

Property Assessment Change Notices (PACNs)
MPAC periodically sends PACNs to property owners when there is a change in a property (such as new construction or major renovation).
MPAC updates the assessment and mails a Notice to property owners. The MPAC graphic below explains why property owners receive a PACN, how the assessed value is different than the market value, and why the valuation date is fixed at January 1, 2016. If you have further questions about your Notice, please go to and log on to AboutMyProperty to learn more.

Key Messages for Property Owners
Property owners are able to access when they receive their  Property Assessment Notice in the mail. Login details are included on every Notice mailed. Visitors to the site can also view videos explaining assessment.

When owners receive their Property Assessment Notice, they should review it. No further action is required unless an owner has questions or disagrees with their assessed value or classification. If an owner doesn’t agree with their assessment, they have the option to file a request for reconsideration (see link to video below).

Farm Property Class Tax Rate Program
To request that a property be eligible for the farm property classes, a request must be filed with the Agricorp. Agricorp is assuming the role of primary point of contact for the Farm Property Class Tax Rate Program, also known as the “Farm Tax Program,” effective February 25, 2019.
The Farm Tax Program is staying the same, but farmland owners will now contact Agricorp for eligibility and enrolment, instead of the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA).
Managed Forest Tax Incentive Program
To request that a property be eligible for the managed forest tax incentive program, a request must be filed. More information is available on this website
