Frequently Asked Questions

The Property Income and Expense Return (PIER) is an online tool, available through, where owners of income producing properties can submit their property rental, income and expense information directly to MPAC. PIER provides property owners a convenient, efficient and accurate way to submit their data.

Property owners can use the PIER tool to submit rental, income and expense information for the following property types:

  • Commercial
  • Industrial
  • Multi-residential
  • Mixed use
  • Golf Courses
  • Gravel Pit and Quarry
  • Hotel
  • Motel
  • Mobile Homes and Land Lease Properties
  • Retirement Homes

PIER is currently not configured to receive submissions for the following property types:

  • Large Resort Properties
  • Long-term Care Facilities
  • Mixed Use Retirement Properties
  • Special Purpose Business Properties
  • Speciality Properties

These property types will continue to submit hard copy returns and will receive a request letter from MPAC in spring 2019.

Through independent research and ongoing work with industry associations, MPAC understands that property owners want a more efficient and streamlined data submission process. A 2014 survey indicated 75 per cent of commercial, industrial and multi-residential property owners would likely use a web-based tool for data submission.

Property owners play a key role in helping MPAC deliver accurate values by providing complete and accurate data. Edit checks and field validations are built into the PIER tool to reduce discrepancies and errors. This will improve the accuracy of commercial, industrial, multi-residential and hospitality property assessments.

The online submission process makes it faster and easier for property owners to submit information, while ensuring MPAC captures the key data required to deliver accurate and consistent property assessments.

Complete and accurate information also enables MPAC to provide more comprehensive disclosure for property owners. This supports MPAC’s commitment to transparency and sharing information with property owners to enable them to better understand their property assessment.

Other benefits include:

  • A more efficient and accurate method than the old paper-based process
  • Access to pre-populated forms that will save property owners time and money
  • A more timely, focused review of the rental, income and expense information submitted
  • A secure online data exchange environment

Several additional factors are considered when determining which income producing properties are subject to the PIER program, including how the property is typically viewed in the marketplace by investors and the availability of market data.

MPAC is required to exclude any income attributable to third party signs (billboards) located on your property from your assessment. Reporting this information separately ensures that rental income from third party signs (billboards) isn’t included in your total income.

Third party signs (billboards) are assessed using the cost approach (replacement cost new, less depreciation) to determine the contribution made by a billboard to the current value of the property on which it is located. No value is added for any income attributable to the third party sign (billboard) or its placement on the property.

MPAC will mail a request letter to all PIER - eligible property owners on May 15, 2019, with a submission deadline of July 15, 2019.

Yes, your agent may submit information on your behalf through AboutMyProperty™ provided that you expressly authorize them to do so and you receive your agent's prior written agreement to comply with the AboutMyProperty™ Terms and Conditions of Use. Since MPAC does not issue login credentials to agents, they will have to use the login credentials that you received from MPAC.

IMPORTANT: Please be aware that providing your login credentials to your agent allows them access to all information about your property, your lease/tenancy details and all AboutMyProperty™ functions. This includes but is not limited to various financial, property and other reports, filing a Request for Reconsideration, and updating information for your property. MPAC strongly suggests that you change your AboutMyProperty™ password immediately after your agent has submitted your Property Income and Expense Return.
