How You are Assessed:

  • The principal benchmark used to assess property is current value (market value, actual value).
  • Current value is considered to be the most likely selling price a willing buyer would pay and a willing seller would accept in an open market, where both parties are under no pressure either to buy or sell the property.
  • When fairly assessed, similar properties located in a similar area will be assessed at a similar rate, resulting in the payment of similar taxes.
  • It is important to note that there are five (5) major factors which account for 85% of the home’s value
    • 1. Location
    • 2. Living area (square feet)
    • 3. Age of the property
    • 4. Lot size (lot dimensions)
    • 5. Quality of construction

Assessment Notices

Every four (4) years, MPAC conducts a province-wide Assessment Update and mails Property Assessment Notices (PANs) to every property in Ontario.

MPAC is currently in the process of updating the assessed values for every property in Ontario for the new four year assessment cycle for taxation years 2021–2024, and as a result, every property owner in Ontario should expect to receive a Property Assessment Notice (PAN) from MPAC updating the value of their property based on a valuation date of January 1, 2019.

Notices are expected to be delivered in the second half of 2020.

Under the phase-in provisions in the Assessment Act:

  • a) Increase in assessed value is introduced gradually over four years (25% each year).
  • b) Decrease in assessed value is introduced immediately.

What if I disagree with my Assessed Value or Classification?

  • If a property owner disagrees with their property’s assessed value or classification, MPAC will review the assessment free of charge by way of the Request for Reconsideration (RfR).
  • The deadline for filing the RfR is 120 days from the Issue Date of the PAN.
  • Login information for the RfR can be found on the Property Assessment Notice.

Not satisfied with the result of your RfR?

You have 90 days after MPAC has notified you of it s decision on your RfR to file an appeal with the Assessment Review Board (ARB). The ARB is an independent tribunal of the Ontario Ministry of the Attorney General and has its own appeal process. See Assessment Review Board or phone 1-800-263-3237.
