Role of the Appointee

Appointees (adjudicators) at Tribunals Ontario hold hearings, make rulings, review and analyze evidence and make decisions. Because the adjudicator is neutral, they cannot provide legal advice or tell you how to present your case. It is up to you to present evidence that supports your position. The adjudicator may ask questions during the hearing. When the hearing is over, the adjudicator might tell you their decision right away or they might "reserve" the decision, which means they will take more time to consider your evidence and submissions. In either case, you will receive the decision in writing. This decision is sometimes called an order.

How our Adjudicators are Appointed

Our adjudicators are appointed using an open, merit based recruitment process. Here are the full position descriptions for Adjudicator, Associate Chair and Vice Chair. Adjudicator are Order-in-Council appointees. The Public Appointments Secretariat website has more information on the appointments process.
