Assessment Information Requests

NOTICE: Prior to the postponement of the 2020 Assessment Update, MPAC was preparing to launch its 2020 Property Income and Expense Return (PIER) campaign in May. MPAC collects income and expense information annually to ensure data accuracy and currency, and in support of our commitment to quality, traceable assessments. In response to the extraordinary circumstances connected to the COVID-19 pandemic, the 2020 campaign is also being postponed to a later date. The revised dates will be shared with you, once finalized.


The Assessment Information Request portal on AboutMyProperty is an easy-to-use online tool that allows owners of specific property types—who have received a request letter from us—to submit property information. 

By filing your Assessment Information Request online, you help us ensure that the assessed value for your property is based on up-to-date and accurate information.

If you have received a request letter from us and are the owner of a property in one or more of the following categories, you are required to submit your property information by the deadline included on your request letter. 

  • Commercial properties
  • Office properties
  • Retail properties
  • Gravel pit and quarry
  • Golf course
  • Grain elevator
  • Hotel
  • Industrial malls
  • Large resort properties
  • Land lease or mobile home park
  • Long-term care facilities
  • Mixed-use properties
  • Mixed-use retirement properties
  • Motel
  • Multi-residential
  • Retirement home
  • Special-purpose business properties
  • Speciality properties

Property Income and Expense Return (PIER) 

If you are the owner of an income-generating property, you may be required to submit your Property Income and Expense Return (PIER) to us. A PIER contains the documentation of rental, income and expense information for your property. 

You must file your property income and expense information each year so that we can analyze the rental, income and expense trends for your property over a four-year period and to assist in establishing quality, traceable assessments.

If you do not receive a letter but believe you should have, please contact us.
