Property Assessment

The Municipal Property Assessment Corporation (MPAC) has been legislated to administer all information contained on the returned assessment roll, including owner's name/s, mailing address, legal description, property code, tax classes, and property assessment values.

For information regarding your property tax class and/or assessment value, visit MPAC's About My Property module. You will require a copy of your latest assessment notice on which you will find your user ID and password located in the bottom right corner of your notice.

All properties in the Province of Ontario are currently assessed at a January 1, 2012 assessment base value. These values have been determined through various means, the most common of which is real estate sale stats from non-distress sales - a sale between a willing buyer and a willing seller. In the event you do not agree with the information, assessment value, or tax class contained on your assessment notice and you wish to renegotiate the assessment value indicated on your notice please contact the Municipal Property Assessment Corporation directly.

Properties at Current Value Assessment Tax Level

In 2009 the Province enacted legislation that gave Municipalities authority to pass a By-Law stipulating that properties which were at CVA Tax in 2008, or that would cross over CVA Tax in the following years, could be excluded from the capping calculation process.

Property tax classes included in the capping process are:

  • Commercial
  • Industrial
  • Multi-residential

The Town of Gananoque has passed such a By-Law - please refer to current year's Final Tax Levy By-Law in the By-Law section.
