Role of appointees

Appointees (also known as “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 immediately 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.

Appointments process

As required by the Adjudicative Tribunals Accountability, Governance and Appointments Act, 2009, and to ensure skilled and qualified individuals are identified, Tribunals Ontario employs a rigorous, competitive, and merit-based selection process for the appointment of adjudicators. Based on the results of this process, the Executive Chair makes recommendations for new appointments and reappointments to the Attorney General of Ontario.

Once approved, and on the recommendation of the Attorney General, the Lieutenant Governor signs an Order-in-Council appointing an individual as an adjudicator to a Tribunals Ontario constituent tribunal. From the time an adjudicator is appointed, it takes on average about six months for the adjudicator to complete their training period before they are able to take on a full schedule of hearings and other adjudicative matters.

Our adjudicators are identified using an open, merit-based recruitment process and appointed by Order-in-Council. The Public Appointments Secretariat website has more information on the appointments process.
