Canada's trade patience has officially run out. After trade talks collapsed, Ottawa announced retaliatory tariffs of up to 50% on US products totaling ~$20B in imports, effective Sept. 8. Prime Minister Mark Carney pledged to match Washington "dollar for dollar," though he acknowledged the move "will raise costs and reduce choice for Canadians."
- Steel and aluminum tariffs double to 50%, while cheese, dishwashers, and seafood face 25% duties, and electronics and tools get hit with 15%.
- Canada paired the tariffs with a C$7.5B (~$5.4B) support package covering loans and income supplements for affected firms and workers.
Retaliation's cost: Ottawa’s measures target just 7% of annual US imports, but the economic fallout could extend much further. Strategist Karl Schamotta calls countertariffs “effectively taxes on domestic consumption,” while Trump’s threat to double auto tariffs could put Canadian plants that send more than 90% of their output abroad under pressure. For Ottawa, hitting back without inflicting more pain at home is becoming a harder balance to strike.
