Assessment Information Requests
With properties frequently undergoing changes and market conditions continuing to evolve, MPAC requires up-to-date property information to maintain an accurate database, supporting the delivery of annual assessment rolls and quality assessments.
Each year, MPAC requests property information from property owners and/or their representatives as part of our Assessment Information Request Program. Having complete, accurate and current market and property data is critical to the valuation process, and property owners play a vital role by providing this information to MPAC.
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 submit it.
Compliance requirements
Property owners are required to comply with MPAC’s requests by submitting information through the Assessment Information Request portal in AboutMyProperty or by providing completed forms through hard copy paper or email submission. We also offer B2B options as well as other file-sharing solutions. To learn more about file-sharing solutions, please contact AIR@mpac.ca.
Property owners are required to comply with MPAC’s information request as outlined in section 11 of the Assessment Act. Learn more about MPAC’s Authority to Collect Information.

MPAC’s largest assessment information request campaign is the Property Income and Expense Return (PIER), where we request rental, income and expense information from income-generating properties, such as retail stores, hotels, motels, multi-residential properties, golf courses, offices and industrial malls.
Each year MPAC sends approximately 35,000 request letters as part of PIER to eligible properties to inform our analysis. Collecting information annually allows MPAC to identify and track trends in revenues, expenses, capital expenditures, fair market rents, vacancies and more over time.
Property owners have an important role to play in the valuation process including the submission of income information through the formal collection process. The requirement for owner compliance is outlined in section 11 of the Assessment Act.
NOTE: The deadline to submit your 2024 PIER information has passed. More information about the 2025 campaign will be available soon.

Properties that have undergone a change to accommodate a senior or a person with a disability are eligible for a property tax exemption. In order to continue to qualify for this exemption, property owners must respond to MPAC’s information request to ensure they meet the criteria.
