Due to a potential service disruption at Canada Post, mail services may be impacted at our tribunals. In the event of a service disruption, parties are asked to use online options such as e-filing portals where available, or email.
If email or online options are not available, parties may also use courier services to send their documents. If you, or a party, are waiting to receive documents from a tribunal, email or a courier may be used.
If you have any questions, please contact the tribunals.
