The US-Canada trade war in 5 charts

August 31, 2026

The United States and Canada are engaged in an escalating trade dispute that began when President Trump imposed tariffs on Canadian steel, aluminum, lumber, and automobiles roughly 18 months into his second term, with an additional 50% levy recently placed on approximately $20 billion worth of Canadian goods. Canada has responded with matching counter-tariffs targeting $28 billion in American products, strategically aimed at swing states like Ohio, Illinois, and Pennsylvania ahead of upcoming midterm elections. Ontario has suffered the most severe impact in Canada, losing tens of thousands of manufacturing jobs, while Quebec's metal exports have plummeted by 36%.

Who is affected

Ontario residents and manufacturing workers (tens of thousands of job losses)
Quebec metal industry workers (3.6% employment drop in the sector)
British Columbia, Quebec, and Ontario residents (most impacted by latest tariffs)
US swing states: Ohio, Illinois, and Pennsylvania (hardest hit by Canadian counter-tariffs)
Canadian businesses that export to the US
American manufacturers in steel, laundry machines, and farm equipment sectors
Prime Minister Carney's government
President Trump's administration

What action is being taken

The US is imposing tariffs on Canadian steel, aluminum, lumber, automobiles, and an additional 50% levy on C$28 billion of Canadian goods
Canada is implementing "dollar-for-dollar" counter-tariffs on C$28 billion worth of US goods including steel, furniture, cosmetics, and toilet paper (effective as of September 8)
Canadian firms are exporting more to non-US countries
Several Ontario auto parts and assembly plants are announcing layoffs and production cuts

Why it matters

This trade dispute represents a significant deterioration in one of the world's most economically integrated trading relationships between neighbors who have maintained free trade agreements since the 1980s. The tariffs are forcing a fundamental restructuring of Canada's export-dependent economy, which has historically sent over 70% of its exports to the United States. The strategic targeting of US swing states could influence American electoral politics, while the job losses and economic disruption in Canadian manufacturing provinces may have lasting domestic political and economic consequences for both nations.

What's next

Prime Minister Carney has pledged to double Canada's non-US exports over the next decade.
