Canada fired back on August 25 with retaliatory tariffs on C$27.6 billion of U.S. imports, effective September 8. The counter-tariffs range from 15% to 50% across 874 product categories, matching U.S. rates dollar-for-dollar after negotiations collapsed on August 21. Steel and aluminum face 50% duties, while paper products, dairy, and seafood are also targeted. The escalation threatens price increases for Canadian and U.S. consumers.
What Canada is targeting
Canada’s retaliatory tariffs hit hardest on steel and aluminum, which account for 31% of the counter-tariff list at 50%. Fish and seafood represent nearly a third of all tariff lines at 25%. Other sectors include dairy at 5.8% of items, machinery at 5.7%, textiles at 3.7%, and aluminum at 3.3%. The tariffs cover goods representing 4.5% of Canada’s total imports from the United States, calculated using 2024 trade figures.
Why toilet paper and vehicles will cost more
The U.S. imported $328 million worth of toilet paper from Canada in 2024, making Canada by far the largest exporter to America. Procter and Gamble, owner of Charmin, said it would raise prices amid tariffs. On vehicles, Trump threatened 50% tariffs on Canadian-built cars and parts starting January 1, 2027, double the current 25% rate. Paper products are among the hardest-hit sectors, with retailers including Costco sourcing much of their supplies from Canada.
The deal that fell apart
On August 19, President Trump announced on Truth Social that America was approaching a deal with Canada, pausing 50% tariffs. By August 21, the deal collapsed over unresolved issues including tariff relief for medium and heavy-duty trucks. The proposed agreement would have cut the top-line tariff on Canadian cars and light-duty trucks from 25% to 15%, with credits for U.S.-made content potentially reducing the effective rate further. Trump’s new 50% tariffs on $28 billion CAD in Canadian goods took effect on August 24.
Canada’s political strategy and support package
Industry Minister Mélanie Joly said the tariffs were selected with upcoming U.S. midterm elections on November 3 in mind, targeting products from states likely to feel economic pain. Canada announced C$7.5 billion in support for affected businesses and workers, including C$500 million in business liquidity, a C$2 billion diversification fund, and C$3.5 billion in worker support. Finance Minister François-Philippe Champagne framed the response as protecting Canadian manufacturing and workers harmed by U.S. duties.
Final Thoughts
Canada’s September 8 tariffs mark an escalation in a trade war that threatens price increases across consumer goods and autos on both sides of the border. With negotiations stalled and January 1 auto tariffs looming at 50%, investors should watch for further deal attempts before year-end.
