Using the services of an agent

If an agent is submitting your property information for you, you will need to give them your AboutMyProperty login credentials as MPAC does not issue separate credentials to agents. Before giving your agent your credentials, you should:

  • Expressly authorize your agent to access your AboutMyProperty account.
  • Obtain written agreement from your agent to comply with AboutMyProperty’s Terms and Conditions of Use.
  • Be aware that by giving your login credentials to your agent, you give them access to all information about your property, your lease/tenancy details and all AboutMyProperty functions. This includes but is not limited to: 
    • financial information
    • property information
    • other reports
    • filing a Request for Reconsideration
    • updating your property information

We strongly suggest that you change your AboutMyProperty password immediately after your agent has submitted your Assessment Information Request.
