After you file an appeal with the Assessment Review Board (ARB), the ARB will assign a Commencement Date and Schedule of Events for due dates to complete work on your appeal.

The ARB has two hearing proceedings with different requirements: the Summary proceedings and the General proceedings. Your appeal will be placed (or “streamed”) into a Summary proceeding or a General proceeding based on the Chair’s Streaming Strategy .

Be advised that the ARB will only provide Schedule of Events notice copies to parties of newly filed self-represented General or Summary Proceedings. The ARB will continue to assign a Commencement Date with Schedule of Events to all new General or Summary proceedings and updated Master lists for both streams will continue to be posted on the ARB’s website. This information will be updated on the 1st of the month, or on the next business day if the 1st of the month falls on either a weekend or holiday. Parties are required to check the Master lists at the beginning of each month to see if a Commencement Date has been set for their appeal. The Master lists can be found under General Proceedings and Summary Proceedings tabs.

In the event any information is incorrectly captured in either General or Summary master lists, contact the ARB at ARB.Registrar@ontario.ca and provide the roll number, appeal number, requested correction, and any supporting documentation for the change.

Overview

After you file an appeal, the Assessment Review Board (ARB) will assign a Commencement Date and Schedule of Events for due dates to complete work on the appeal. Your appeal will be placed (or “streamed”) into a Summary proceeding or a General proceeding based on the Chair’s Streaming Strategy .

Schedule of Events

A Schedule of Events provides the parties with mandatory deadlines for each step in their appeal. Each property will have an associated Schedule of Events. The timelines for General and Summary proceedings will differ, as General proceedings are more complex. After a Commencement Date is assigned to an appeal, the ARB will notify the municipality, the Municipal Property Assessment Corporation (MPAC) and appellant/representative of the assigned Schedule of Events.

Commencement Date

The Commencement Date is the day from which all due dates in the Schedule of Events are calculated. There are no required steps on any appeal until the Commencement Date. Starting on the Commencement Date for your appeal, the work on the appeal must begin. Once that work begins, the time continues to pass. The due dates in the Schedule of Events do not change, even if there are motions to the ARB, other steps are added, or the parties notify the ARB the matter is resolved without executing minutes of settlement.

Mandatory Meeting

The parties must schedule and hold a meeting between all the parties to the appeal before 36 weeks after the Commencement Date. This is your opportunity to discuss the issues in the appeal and attempt to come to some agreement. After the Mandatory Meeting, MPAC must file the Mandatory Meeting Form with the ARB, notifying the ARB of next steps.

When to Request for Early Scheduling of Settlement Conferences

You may submit a written request to the ARB for early scheduling of Settlement Conferences if you are able to complete all the events Schedule of Events earlier than required. Your written request must be made using the Expedited Board Directions Form . The requesting party must provide the ARB with written confirmation of the following:

• whether all parties, including the municipality, consent to the request
• all events in the Schedule of Events have been completed
• the date on which each party will file the documents set out in Rule 35 and settlement conference brief
• an acknowledgement by all parties that Rules 48 and 49 will apply from that filing date

The ARB will only schedule Settlement Conferences once all the required documents have been submitted. The due dates set out in the prescribed Schedule of Events are still in full effect. If the parties are unable to come to a resolution after the Settlement Conference, the ARB will not grant an extension of the Schedule of Events. Parties cannot request scheduling of a hearing unless Settlement Conferences have been completed.

The ARB will only provide ‘Schedule of Events’ notice copies to parties of newly filed self-represented General proceedings. The ARB will continue to assign Commencement Dates with Schedule of Events to all new General or Summary proceedings and updated Master lists for both streams will continue to be posted on the ARB‘s website. This information will be updated on the 1st of the month, or on the next business day if the 1st of the month falls on either a weekend or holiday.

Parties are required to check the Master lists at the beginning of each month to see if a Commencement Date has been set for their appeal. The Master list can be found under General Proceedings.

In the event any information is incorrectly captured in the General proceedings list, contact the ARB at ARB.Registrar@ontario.ca and provide the roll number, appeal number, requested correction, and any supporting documentation for the change.

How to Prepare for a Hearing

Your Role

It is important that you come prepared to your ARB hearing or Settlement Conferences. Although it is MPAC‘s responsibility to explain its valuation of your property, you should still provide evidence to back up your case. This evidence must be filed in accordance with the due date in your Schedule of Events, and could include:

• detailed property information such as location, lot size, square footage, age of building, and the number of rooms and stories
• detailed information, as above, on comparable properties in the same area as your property
• sales information on your property and comparable properties
• assessed values of your property and comparable properties
• photographs of your property and comparable properties
• any other evidence you think will help prove your case

Settlement Conferences

Settlement Conferences occur in General proceedings. It is an appearance before the ARB prior to the scheduling of a hearing, where an ARB Member will meet with the parties to review the issues in dispute, to clarify and attempt to resolve some or all the issues. If the parties do not come to an agreement, the Member may determine that the next step is a hearing.
