The trade dispute between the United States and Canada has intensified following the expansion of tariffs on Canadian goods by President Donald Trump and subsequent retaliatory measures from Ottawa, according to a report by the BBC. The United States has targeted Canadian steel, aluminum, lumber, and automobiles, prompting Canada to impose retaliatory tariffs on 28 Mrd.
Economic Impact Across Canadian Provinces
Ontario has absorbed the most severe economic impact, with auto parts and assembly plants announcing layoffs and production cuts according to the BBC report. In Quebec, metal exports dropped by 36% between February 2025 and 2026, while industry employment fell by 3,6%. The Royal Bank of Canada identified Ontario and Quebec as the most exposed provinces, noting that additional U.S. tariffs on roughly 20 Mrd. US-Dollar in Canadian goods enacted on August 22 are expected to weigh heavily on British Columbia, Quebec, and Ontario.
Canada lost approximately 55.000 manufacturing jobs between January 2025 and January 2026. Trevor Tombe, an economist based in Calgary, estimated that nationwide job losses could reach 90.000 if the latest U.S. tariffs remain in place. Despite these regional manufacturing contractions, Canada’s gross domestic product grew by 3,3% in the second quarter of 2026, supported by stronger exports and domestic investment.
Retaliatory Measures Target American Swing States
On the American side, Canada’s countermeasures focus strategically on political swing states. Derek Holt, an economist at Scotiabank, stated that the retaliatory tariffs appear tailored to target states capable of shifting the balance of power in upcoming midterm elections. Ohio stands as the most affected state, facing tariffs on 3,2 Mrd.
Data from the Royal Bank of Canada shows that the average effective U.S. tariff rate on Canada climbed to 5,7%, up from 2,9% in June. By comparison, the U.S. tariff rate on the United Kingdom sits at 6,2%, while China remains at approximately 20,5%. Facing these tariff pressures, Canadian businesses have increasingly exported to countries outside the United States since Trump’s return to the White House in January 2025. Foreign direct investment into Canada reached 96,8 Mrd. Meanwhile, the Tax Foundation estimated that an average U.S. household could pay $840 more this year due to the Trump administration’s tariffs.
