ARB: Operational Update
Assessment Review Board’s (ARB) Digital-First Approach – Update


The ARB is committed to supporting Tribunals Ontario’s digital-first approach through the continued enhancement and development of key initiatives that leverage modern tools and technology.

As part of that commitment, the ARB has completed upgrades to its e-filing system that were identified in ARB memos dated January 29, 2021, and June 18, 2021. See links below:

Effective December 1, 2022, some tax appeals related to the City of Toronto Act (COTA) and the Municipal Act can be e-filed.

The ARB identified the top six most submitted tax appeals and based on our findings the following sections were added to our e-filing system:

  • Municipal Act: 357 (7), 357 (8), 357 (1)(d1)
  • City of Toronto Act: 323 (7), 323 (8), 323 (1)(e)

All assessment appeals must continue to be filed through the e-filing system only.

With this improvement to the e-filing system the “excel batch filing” process will be eliminated.

e-File is a fast, secure, reliable, and “real-time” filing system to file and pay for your appeal. You will receive immediate confirmation of receipt of your appeal upon completion of e-filing. E-filing eliminates the delays from mailing your appeal to the ARB and having it processed manually.

Some of the digital services we would like to remind you of include:

ARB Website:

Our website is the main portal to access information about the Board. By visiting our website, you can:

  • find information about managing the appeal process and news updates
  • access our e-Services and other important resources
  • view appeals and appeal commencement dates, which are updated monthly
  • review the ARB Rules of Practice and Procedure
  • download forms
  • stay informed about operational updates

Tax Calculator:

This is an interactive online tool that helps potential appellants calculate estimated savings from a possible change in assessment value. Potential appellants can determine if any possible savings offset the costs related to filing an appeal.

Thank you for your continued support.
