Canada will fight U.S. President Donald Trump's tariffs with countermeasures, Prime Minister Mark Carney said on Wednesday.

On March 4, 2025, U.S. tariffs of 25 per cent on Canadian goods and 10 per cent on energy and potash exports from Canada to the U.S. came into effect. On March 12, 2025, the U.S. imposed tariffs of 25 per cent on Canadian steel and aluminum products.

Canadian Prime Minister Mark Carney confirmed that his country would be excluded from President Trump’s reciprocal tariffs, although they are still subject to a 25% tariff on most imports to the U.S.

The old relationship we had with the United States ... is over,” Canadian Prime Minister Mark Carney declared.

Prime Minister Mark Carney says Canada will match U.S. President Donald Trump’s 25% auto tariffs with a tariff on vehicles imported from the United States.

As Canada and the European Union brace for impact, leaders vow to implement countermeasures in response to President Trump's sweeping tariffs on imports.
