Canada’s dollar-for-dollar tariffs take effect as Trump targets Bombardier

Canada’s counter-tariffs on United States goods came into force, targeting hundreds of American imports on a dollar-for-dollar basis^1,2,5. A 50 per cent reciprocal rate applies to products including cheese, milk and steel³. Multiple steel and aluminium products move to 50 per cent, up from the previous level⁵.

Prime Minister Mark Carney said the retaliation was unavoidable. “There’s always a cost to action,” he said⁶. He also vowed to backstop the economy as the dispute escalates¹². US Commerce Secretary Howard Lutnick said Canada was the party that disrupted negotiations, and for political reasons¹⁶.

Why it matters to investors

The measure creates a two-way tariff wall across the continent’s most integrated supply chains. Mexican automotive, steel and aluminium producers remain exposed to the regional disruption even though they are not party to the exchange¹⁴. Bank of Canada Governor Tiff Macklem said last week that the intensification of trade tensions posed a risk to economic momentum¹².

Corporate responses are already visible. Sapporo plans to shift some beer production from Canada to the United States following a 50 per cent tariff on beer imported from Canada¹⁵. President Trump has threatened to stop the sale of Canadian Bombardier jets in the United States, a threat aimed at one of Canada’s largest companies¹⁰. Bombardier contributed C$7.4bn, or $5.4bn, to Canadian GDP in 2024, according to a report commissioned on its behalf¹¹.

For consumers, the pass-through is the open question. Experts say importers may choose to pass the measures along, and everyday items are reported as candidates to cost 50 per cent more^4,7. Businesses on the border are already reporting the effect: coverage in Vermont and New York describes firms adjusting to the new reciprocal rate on American food and steel products as soon as it took force³.

What to watch

The size of the retaliation is reported inconsistently. One account puts it at $28 billion of US goods, another at about $20 billion^8,13. That gap matters for estimating the inflation impulse, and it has not been reconciled across the coverage.

The near-term trigger is Washington’s response. US Trade Representative Jamieson Greer said he would consider imposing further tariffs on Canadian goods as early as the same day⁸. A call was scheduled between Greer and Canadian trade minister Dominic LeBlanc, though the Canadian side offered no assurance of progress⁹.
