A second Canada Post strike, worsened by U.S. tariffs, has crippled small businesses with shipping failures and financial losses.

A second Canada Post strike in under a year has disrupted small businesses nationwide, worsening challenges from new U.S. tariffs. Merchants relying on affordable, reliable shipping—especially online sellers—report lost sales, stranded inventory, and delayed payments. Some, like an artist in B.C. and a vape shop owner in Ontario, lost key shipping methods or over $30,000 in goods. Others, including a family-run supplier in Ontario, switched to alternative payment systems after postal delays. A knitter in Alberta faces no viable shipping to the U.S. after tariffs and a courier’s exit. Many business owners say the combined impact of labor actions and trade policies is making survival nearly impossible.
