U.S. President Donald Trump signed an order Saturday to impose tariffs of 10 per cent on Canadian energy and 25 per cent on everything else beginning on Feb. 4.
Statistics Canada says the value of Canadian exports to the United States in 2023 exceeded $594 billion.
More than 43 per cent of that came from just six industries: oil and gas extraction, oil and gas refining, auto manufacturing, aluminum production and processing, aerospace and crop and animal production
The U.S. is by far Canada's largest trading partner. While Canada's total exports to the U.S. from all industries came to $594 billion in 2023, its total exports to all other countries combined reached only $174 billion — meaning more than 77 per cent of all Canadian exports went to the U.S.
Here's a look at the industries that will be hit the hardest:
