The U.S. Postal Service says it will indefinitely suspend deliveries of international mail to Canada due to a strike by the Canadian Union of Postal Workers.

Last week, the U.S. Postal Service announced it was temporarily suspending international mail acceptance to Canada because of the strike.

The U.S. Postal Service announced Friday it is not taking mail ear-marked for Canada. The USPS move comes after roughly 55,000 Canada Post employees went on strike last month. SEE ALSO: Mail carrier celebrates Thanksgiving with Illinois man after helping save his life
