On September 26, 2025, Canada Post announced a shutdown due to national labor actions between Canada Post and the Canadian Union of Postal Workers. As a result, notices sent through the BNC between October 2, 2025, and October 16, 2025, were not mailed to recipient addresses that include the country name "Canada" in the last line of the address; these notices were bypassed. Bypassed recipients are listed within the bypass section of the Certificate of Notice.  

As of October 10, 2025, the prior general strike has been updated to a rotating strike; and as of October 17, 2025, the BNC will resume mailing notices to Canada, but significant delays are expected. Additional updates will be provided as information is made available.
