MPAC Delivers Property Assessment Notices to Nearly One Million Property Owners 2015

PICKERING, Ontario, October 27, 2015 – Starting today the Municipal Property Assessment Corporation (MPAC) will begin mailing nearly one million Property Assessment Notices to property owners across Ontario to reflect changes in ownership, value, classification and/or school support.

In the fall of 2012, every property owner in Ontario received a Property Assessment Notice as the result of a province-wide Assessment Update. MPAC continues to update property information during non-Assessment Update years as new homes are built, owners renovate, structures are removed and properties change use. The next province-wide Assessment Update will take place in 2016.

“We know it’s important to Ontario property owners that we assess and classify their property correctly,” said Rose McLean, MPAC’s Chief Operating Officer. “Property Assessment Notices mailed in 2015 reflect changes to assessment information.”

Property owners will receive a Notice from MPAC if there has been:

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

Property owners are encouraged to visit to confirm their property details and compare their property with others in their neighbourhood.  The 2015 Notices will include a Roll Number and personalized access key, which can be used to log in to

Property owners who receive a Property Assessment Notice this fall have until March 31, 2016 to submit a Request for Reconsideration (RfR) asking MPAC to reconsider their assessment. For greater convenience, RfRs can now be filed directly through Additional information on how to file has been included with every Notice mailed.
