If customers order from a third-party company that sells items on Amazon.ca and delivers through Canada Post, there may be a delay. Smaller online retailers, like those on Etsy, who use Canada Post, will definitely see an impact. Canada Post says the mail will stay in its warehouses or distribution centres until the stoppage is over. Mail service could be suspended as of Friday after Canada Post gave 72-hours' notice to the Canadian Union of Postal Workers of a lockout. "All other payments, including those to businesses, will not be delivered until regular Canada Post operations resume," the government states.
