The delivery of physical pension cheques by mail may be impacted by flooding or wildfires in areas across Canada. To ensure timely delivery of benefits, those who have not signed up yet are encouraged to sign up for direct deposit. Those affected by hazardous weather can change their address to ensure they receive their cheques. To sign up or to make a change, Canadians can send an eServiceCanada request. A representative will contact them by telephone within 2 business days. They can also call 1-800-277-9914.

Those who still receive paper cheques are encouraged to visit Canada Post for updates and alternate delivery arrangements or pick-up locations.
