MPAC mails more than 800,000 Property Assessment Notices across Ontario

Today the Municipal Property Assessment Corporation (MPAC) will begin mailing over 800,000 Property Assessment Notices to property owners across Ontario. The notices reflect changes in assessment that have taken place over the last year.

While 2019 is not a province-wide Assessment Update year, MPAC continues to review properties and update property information in order to return an accurate assessment roll each year. 

“We know it’s important to Ontario property owners that we assess and classify their property correctly,” said Nicole McNeill, President & Chief Administrative Officer. “Property Assessment Notices mailed in 2019 reflect changes to assessment information and ensure that these changes are accurately reflected on municipal assessment rolls.”

This year, property owners will receive a Notice from MPAC if there has been a:

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

“We encourage property owners to visit to learn more about how their property was assessed, see the information we have on file and compare it to others in their neighbourhood,” said Carmelo Lipsi, Vice President of Valuation & Customer Relations and Chief Operating Officer. 

“If a property owner is still concerned with their property’s assessment, we will review it free of charge through a Request for Reconsideration (RfR), added Mr. Lipsi. “Requests for Reconsideration must be filed by March 31, 2020, for the 2020 property tax year.”

Property owners can login to using their Roll Number and Access Key which is found on their Property Assessment Notice. For greater convenience, RfRs can also be filed directly through
