Assessment Information Requests

Each year, MPAC requests property information from property owners and/or their representatives as part of our Assessment Information Request Program.This annual initiative is crucial to our efforts to maintain accurate property records, deliver quality assessments, and inform changes to Ontario’s property landscape.

Where property information is required, MPAC will send an information request letter outlining what information is needed, when property owners are required to submit the information to MPAC, and details on how to submitit. Property owners are required to comply with MPAC’s requests by the campaign deadline.

We are committed to working with you to improve the way we collect this data. If you have suggestions, please email us at AIR@mpac.ca.
