USPS will resuming sending the packages that have been stuck in limbo and accepting new mail pieces on Monday!
Per usps.com: " The U.S. Postal Service will resume acceptance of mail and packages to Canada starting Monday, Jan. 6, 2025. Canada Post has made significant progress in clearing delayed volumes caused by their employee strike, and now commercial and retail customers, as well as those using online systems, will be able to send mail and packages to Canada once again."
We expect the orders stuck in Canada at the start of the strike has likely been delivered by now. Other parcels held by USPS are also probably moving now and we'll turn over the packages we've been forced to hold as a result of the strike on Monday.
