Updating your information: Business Property Owners 

You are visiting this page because you have recently been contacted by MPAC through a letter and are being asked to call to confirm details about your business property.

Why?

As an owner of a business property, it is critical that MPAC has the correct information on file so we can ensure that your assessment accurately reflects the current state and condition of your property.

Our database, which hosts over 5.5 million properties across Ontario, is the platform in which MPAC uses to create and deliver property assessment notices.

MPAC determines your property assessment and provides it to the municipality for property taxation purposes.

How do I make sure my property’s information is correct?

Please contact us and one of our assessment experts will assist you. If we do not hear from you, we may be required to estimate the property details and complete the assessment.

MPAC has flagged your property as requiring an update because you have:

  • Purchased a business property and/or;
  • Taken out a building permit that may have resulted in physical change(s) to your property.

It is critical that we collect the correct information regarding the state and condition of the property, in order to conduct fair and accurate assessments in your area.

How do I confirm the current information MPAC has regarding my property?

To see the information we currently have on file for your property, please log into AboutMyProperty using the roll number and access key found on your Property Assessment Notice. If you cannot find your Property Assessment Notice, please contact us.
