Property Assessment Notice

In 2016, MPAC mailed a Property Assessment Notice to every property owner in the province – assessing more than five million properties in Ontario. The next province-wide Assessment Update of all properties will take place in 2020.

MPAC continues to review properties during non-Assessment Update years. MPAC is legislatively responsible for updating this information even in a year when a province-wide Assessment Update is not taking place.

Why did I receive a 2019 Property Assessment Notice from MPAC?

You may have received this Notice for one of the following reasons:

  • Property value increase/decrease reflecting a change to the property; for example, a new structure, addition, or removal of an old structure
  • Change to property ownership, legal description, or school support
  • Change to the property’s value resulting from a Request for Reconsideration (RfR), an Assessment Review Board (ARB) decision, or ongoing property reviews
  • Change in the classification or tax liability of the property

Your 2019 Property Assessment Notice shows the assessed value of your property based on a January 1, 2016 valuation date and will be the basis for your property taxes for the 2020 property tax year.

The valuation date, established by the Ontario government, is a fixed day to which all properties are valued. In simple terms, the value is the price your property might reasonably have sold for in its current state and condition on January 1, 2016.

How will my municipality use MPAC’s property assessment?

Your property’s assessed value is used by your municipality to calculate property taxes. Under the phase-in provision in the Assessment Act, an increase in assessed value will be introduced gradually. A decrease in assessed value is introduced immediately. The January 1, 2016 assessed value and classification of your property will be used as the basis for calculating your 2020 property taxes, as illustrated below.

MPAC’s assessed value of your property as of January 1, 2016 $228,000

MPAC’s assessed value of your property as of January 1, 2012 $162,000

Between 2012 and 2016, your property’s assessed value changed by $66,000

If you still disagree with MPAC’s assessment or classification of your property, you can choose to either file an RfR with MPAC or file an appeal directly with the Assessment Review Board (ARB).

If your property, or a portion of it, is classified as residential, farm or managed forest, you must file a Request for Reconsideration (RfR) with MPAC – and MPAC must make a decision before you are eligible to appeal to the ARB. The RfR deadline is March 31, 2020 for the 2020 property tax year.

The fastest way to start the review of your property’s assessment is to file an RfR on This web-based tool allows you to attach pictures and reports to accompany your RfR and check the status of your request. You may also send us your completed RfR form by email or mail.

Please note: Business properties are not required to file an RfR before filing an appeal with the Assessment Review Board. The appeal deadline is March 31, 2020 for the 2020 property tax year.
