Canadian counter‑tariffs hit US goods at up to 50% amid stalled talks, threatening a long trade dispute.

Canada’s new counter‑tariffs—effective this Tuesday—target roughly C$28 bn of U.S. products, from steel to T‑shirts, with a maximum vignette of 50%. Prime Minister Mark Carney calls for a durable deal, while U.S. trade rep Jamieson Greer argues the U.S. has chosen the “best” offer. Both sides have stalled negotiations, sparking uncertainty for businesses on both sides. Canadian firms warn of price hikes; the Chamber urges a surgical approach to retaliation. The trade war threatens a slowdown from a recent 3.3% GDP growth and 181,000 job gains.

Canada Boots Retaliatory Tariffs as U.S. Trade War Intensifies

Canadian counter‑tariffs, effective Tuesday, hit nearly C$28 bn of U.S. goods—from steel and furniture to cotton T‑shirts—and can reach 50%.

Fresh fish and lobster were originally included, but were dropped after pushback from Canada’s seafood sector, underscoring the delicate balance in retaliating against its main trading partner.

Prime Minister Mark Carney said Canada remains "searching for a durable deal" that benefits both nations, while U.S. Trade Representative Jamieson Greer asserted that the U.S. has already offered the best package and that Canadians have rejected it.

U.S. tariffs stand at 25% on Canadian cars and trucks and on steel, aluminium and lumber, with August 2026 Trump posts warning of a 50% tax on dairy, alcohol, hockey sticks and perfume.

Carney described Canada’s counter‑tariffs as "dollar‑for‑dollar" and noted they will not only cover the new 50% block but also existing duties on American vehicles that violate the USMCA/CUSMA agreement.

Business leaders report scrambling to mitigate the fallout. The Canadian Chamber of Commerce urges a careful, targeted response, saying “endless escalation” would be detrimental, but acknowledges the dispute may lengthen.

Economic data suggests resilience: Canada’s GDP rose 3.3% in Q2 and it added 181,000 jobs from April to July, though August saw a 41,000‑job loss coinciding with new U.S. tariffs and collapsed talks.

Manufacturing saw a modest rise, the government credits to increased demand for domestic products.

Cars as a critical sector: Prime Minister Carney aims to diversify exports away from the U.S., noting Canada‑bound U.S. shipments fell to 66% from a pre‑war average of 75%.

Interviews with President Donald Trump on Truth Social criticized Canada’s exchange rate and threatened to halt Bombardier operations—Bombardier contributes over C$7 bn to Canada’s GDP.

The trade war’s implications for consumers loom: economists warn that retaliatory tariffs will push up everyday prices for clothing, food, and furniture.

International poll data show a majority of Canadians support imposing retaliatory tariffs on the U.S., yet economic experts caution against a prolonged dispute.
