Designated industrial property owners will receive a request for information (RFI) from the provincial assessor’s office before the end of the assessment year.

The package contains a RFI guide and/or reference, as well as a pre-populated inventory that shows current provincial database records for your designated industrial property.

This is an opportunity for property owners to participate in the assessment of their properties by updating, adding, removing or otherwise correcting inventory details.

The RFI indicates a deadline for the response. It is important to respond to this request in a timely manner as it may impact the eligibility of future complaints filed against the resulting assessment.

The RFI is just one of the methods that the provincial assessor’s office uses to collect data on properties.

Other sources include data from the Alberta Energy Regulator, Alberta Utilities Commission, the Canadian Energy Regulator (formerly the National Energy Board), and other government departments, along with routine field and site inspections throughout the year.

Letters of authorization

A letter of authorization or renewal is required when someone other than your company staff is requesting or discussing your company’s designated industrial property assessment information.

Letters of authorization are valid for the tax year in which they are filed. A copy of your company’s request for information will also be forwarded to your authorized representative in the current tax year.

Please note that a different authorization form is required when filing an assessment complaint. For more information, please read more on assessment complaints.


Municipalities and property owners may now sign up for epost Connect, Canada Post’s secure and convenient web-based service.

To get started, complete the participation agreement and email a signed copy to ma.ALPASmail@gov.ab.ca.

Please note that if you choose to receive your assessment information electronically, you will still receive a package by regular mail until we are approved by legislation to allow the option of one or the other. You will be notified when this option is available.
