Request for Reconsideration and Appeals Fact Sheet

What you need to know: The basics

Reasons for filing a RfR and/or appeal

Some examples of reasons to file an RfR include:

  • You believe that your assessed value is too high or too low.
  • The property data on your Notice of Assessment or on AboutMyProperty is incorrect. For example, you may want to update the information we have on file on the size of your building or the area of your land.
  • You believe your property classification should be different.
  • You have more than one type of property (or "property classification") listed on your Notice of Assessment, and the portions of assessed value for each class are incorrect. For example, your property may include both commercial and tax-exempt portions.
  • You received a Property Assessment Change Notice that you believe is incorrect.

Who can file an RfR?

You can file an RfR if you:

  • are the property owner
  • received a Property Assessment Notice
  • are the property owner’s representative

Items you may need to support your Request for Reconsideration

You must provide sufficient property-specific reasons and supporting documentation with all Requests for Reconsideration. 

 This may include:

  • photos 
  • sale information 
  • the assessed value for comparable properties, which you can find on AboutMyProperty
  • recent appraisals
  • zoning information
  • estimates for significant repairs (e.g. repairs for cracked and leaking foundation walls, water damage due to flooding, termite damage, sagging roof line, etc.)

How long does it take for MPAC to review an RfR?

  • Generally, MPAC tries to respond to RfRs within 180 days (or less) from when we receive the request. 
  • We may need up to 60 more days to review a property’s assessment. In these cases, we will contact the property owner. 

The Results<

  • We mail a letter with the results. 
  • If changes are required to the property’s classification or assessed value, they will be applied to the property.
  • If the RfR is completed before the return of the Assessment Roll, we will mail the property owner a new Property Assessment Notice.
  • If the RfR is completed after the Assessment Roll is returned, we will mail the property owner Minutes of Settlement for their review, recommending a new value.

Filing an Appeal with the Assessment Review Board (ARB)

The ARB is an independent tribunal (decision-making body) of the Ontario Ministry of the Attorney General and has its own appeal process. More information about how to file an appeal, including forms and fees, is available at tribunalsontario.ca/arb/.

  • A property owner has 90 days after MPAC has notified them of our decision on their RfR to file an appeal with the Assessment Review Board (ARB).
  • The deadline for submitting an appeal to the ARB will be in the letter that MPAC sends the property owner with the results of the RfR. 
  • Please consult the ARB’s website for information about their process and proceedings as well as their response to COVID-19, which may impact your appeal.
