Nearly one million Ontario property taxpayers to receive Property Assessment Notices this fall

Changes in ownership, value, classification, school support trigger mailing of new Property Assessment Notice

PICKERING, ON, Nov. 2, 2011 /CNW/ - Almost one million property taxpayers will receive Property Assessment Notices this fall, according to the Municipal Property Assessment Corporation (MPAC), which began mailing Notices this week.

"MPAC is responsible for updating the assessment information in its database on an ongoing basis," said Carl Isenburg, President and Chief Administrative Officer of MPAC.

"If there have been any changes to a property, we mail a Property Assessment Notice reflecting those changes to the owner of the property," said Isenburg.

Property taxpayers 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 who receive a Property Assessment Notice this fall have until April 2, 2012 to ask MPAC to reconsider their assessment. This will be done at no charge. Details on how to file a Request for Reconsideration have been included with every Notice mailed.

"If property owners have any questions or concerns about their assessment, I encourage them to contact us.  We will help to answer questions and review the information we have on file," said Isenburg.

Property owners can also access detailed assessment information about their own property and comparable properties through AboutMyProperty™ at  Every Notice mailed this fall includes personalized passwords to access AboutMyProperty™.
