Trump's Canada trade war: How we got here
The narrative of the escalating US-Canada trade war begins under the first Trump administration, when President Donald Trump unveiled a series of tariffs on Canadian imports. The tensions peaked when Trump threatened to make Canada the 51st state, prompting retaliatory measures from Canadian Prime Minister Mark Carney. Canada responded with its own tariffs, citing concerns over undocumented immigration and drug trafficking.
The trade tensions continued to rise, with Trump imposing higher tariffs on steel and aluminium, leading to further Canadian retaliation. Despite efforts to negotiate, the relationship remained strained, with Trump threatening additional tariffs and suspending trade talks when a Canadian advertisement opposing the tariffs was aired.
The situation reached a critical point in November 2025 when the US Supreme Court struck down Trump's tariffs, dealing a significant blow to his trade policies.
