MPAC Notices

Every four years, MPAC conducts a province-wide Assessment Update and mails a Property Assessment Notice to every property owner in Ontario. The Notice you received in 2016 is MPAC’s assessed value of your property as of January 1, 2016. The information contained in the 2016 Notice will be used as the basis for calculating your property taxes for the 2017-2020 property tax years.

We continue to update property information during non-Assessment Update years. We are legislatively responsible for updating this information, even when a province-wide Assessment Update is not taking place. 

Notices are mailed to property owners throughout the year to inform them of changes made to their property information.

Note: The applicable law prevails to the extent there is any conflict between this information and the current law. This information is not intended to provide legal advice and should not be relied upon as such.
