March 26, 2020

On March 20, 2020, the Government of Ontario issued an Emergency Order (O.Reg. 73/20) under the Emergency Management and Civil Protection Act.

The order suspends limitation periods and procedural time periods relevant to tribunal proceedings. The suspension is retroactive to March 16, 2020.

If current and / or new parties are not able to meet a timeline, Tribunals Ontario will allow them to do so at a later date. For example, if parties are not able to meet the timeline for submitting an application to a tribunal, they will be able to submit it at a later date.

Tribunals Ontario is continuing to deliver service across the province. Most tribunals are continuing to have hearings, mediations, and case conferences by teleconference or in writing, while some tribunals are rescheduling matters to later dates.

If you are not able to proceed with a matter, please contact the tribunal to reschedule. If you are not able to attend a proceeding by teleconference or in writing, the tribunal will be able to reschedule the matter to another date.
