How is Sonder Mountain impacted by the Canada Post strike?

As of September 25, 2025, the Canadian Union of Postal Workers (CUPW) has launched a national strike that will cause postal delays.

Here’s what you need to know 

• We will use alternative shipping carriers for both domestic and international orders until the strike is over. However, these carriers cannot deliver to P.O. boxes or remote ZIP codes – only Canada Post can do this.
• As of Monday, September 29, we are not fulfilling orders with P.O. boxes or remote ZIP codes listed as the delivery address. It sucks, but there is not much we can do about it at this time...
• Orders that were accepted before September 29 with a P.O. box or remote ZIP code as the delivery address will be held in our facility until the strike is over. If they’ve already moved into fulfillment, they cannot be canceled. 
• We’ll be following Canada Post updates closely, and we remain hopeful for a swift resolution. For the most current information, please visit the Canada Post website.
