The Postal Service™ is continuing to monitor a possible strike or work stoppage affecting Canada Post.

On Wednesday, July 6, Canada Post extended the current 72-hour notice period to Monday, July 11 at 12:01 am; at which time Canada Post can decide to shut down completely or partially.

The potential shutdown could involve service delays for U.S. shipments to Canada of First-Class Mail International® service, First-Class Package International Service®, International Priority Airmail® service, International Surface Air Lift® service, Priority Mail International® service, and Priority Mail Express International® service. Until further notice, USPS will continue to process and accept all classes of mail to and from Canada.

In the event of a full nationwide work stoppage in Canada, USPS will continue to offer customers the option of using Global Express Guaranteed® (GXG®) service for delivery of documents and merchandise in Canada, with transportation and delivery by FedEx.

GXG service is available online and at thousands of participating retail locations throughout the United States.

Additional information and updates about mail service to Canada are available on the Postal Service’s International Service Alert page.
