The US-Canada trade war in 5 charts

The trade tensions between the United States and Canada have intensified significantly since President Trump returned to office, with both nations implementing escalating tariff measures across multiple sectors. The US has targeted Canada’s key industries including steel, aluminum, lumber and automobiles, culminating in an additional 50% levy on approximately C$28 billion of Canadian goods earlier this month. Canada responded on Tuesday with its own reciprocal tariffs on American goods, framed as a strategic response matching the magnitude of US actions.

The economic impact has been distributed unevenly across regions in both countries. In Canada, Ontario and Quebec have experienced the most severe consequences, with Ontario’s auto and steel sectors particularly hard hit following announcements of layoffs and production cuts at numerous facilities. Metal exports from Quebec declined 36% between February 2025 and 2026, accompanied by a 3.6% employment drop in that sector. The Royal Bank of Canada indicates these two provinces face the greatest exposure to sectoral tariffs, while other provinces including Newfoundland and Labrador, Alberta and Saskatchewan remain relatively insulated.

Within the United States, certain states face disproportionate effects from Canadian counter-tariffs. Ohio emerges as most vulnerable, with approximately 12% of its exports targeted, followed by Illinois and Pennsylvania. Economists have noted that Canada’s retaliatory measures appear strategically directed toward swing states with significance in upcoming electoral contests.

Despite assurances from Prime Minister Carney that Canada faces relatively low US tariff rates compared to other nations, the average effective tariff rate on Canadian goods has nearly doubled to 5.7%, now exceeding Mexico’s rate and approaching levels faced by the UK and Vietnam. Given that the US purchases over 70% of Canadian exports, businesses are beginning to explore alternative markets, with some reporting success in European markets. However, regions deeply integrated with US supply chains, particularly manufacturing centers in Ontario, face significant challenges in diversifying their trade relationships. Notably, foreign direct investment into Canada reached C$96.8 billion in 2025, marking the highest inflow since 2007.
