This follows after US President Trump announced on 30 May 2025, that tariffs on Canadian steel and aluminium imports will increase from 25% to 50%.

Canada’s Prime Minister Mark Carney, on 19 June 2025, cautioned that his government may impose counter-tariffs on US steel and aluminium if a trade deal with US President Donald Trump isn’t reached within 30 days.

This follows after Trump’s announcement on 30 May 2025 that his administration plans to raise tariffs on imported steel and aluminium from 25% to 50%, effective 4 June 2025.  The move could impact Canada, the largest supplier of these metals to the US.

Canada sends over 90% of its steel and aluminium exports to the US and consumes about 20% of U.S. steel exports and 50% of its aluminium.

On 16 June 2025, Carney announced that he and Trump had reached an agreement to aim for finalising a new economic and security deal by 21 July 2025.

“Canada will adjust its existing counter-tariffs on US steel and aluminium products on July 21 to levels consistent with progress made in the broader trading agreement with the United States,” said Carney at a press conference.

On 31 March 2025, Canada imposed 25% tariffs on CAD 12.6 billion in steel and CAD 3 billion in aluminium products.

Trump has imposed tariffs on Canadian steel, aluminium, and automobiles, leading Canada to respond with countermeasures.

Earlier, on 30 January 2025, Trump imposed a 25% tariff on imports from Canada.

On 2 April 2025, Trump signed an executive order imposing a 10% baseline tariff on imports from all countries, including Canada, effective 9 April 2025. However, Trump delayed the “reciprocal” tariffs for 90 days. This delay did not apply to tariffs on China.
