President Donald Trump's tariff war - and his repeated threats to annex Canada - are upending decades of close trade ties between the two North American neighbors, and prompting many small-scale Canadian manufacturing firms to revise their long-term business strategies.
Prime Minister Mark Carney, who led the Liberal party to victory last month by campaigning to stand up to Trump, is scheduled to meet the U.S. President at the White House on Tuesday. He has repeatedly said the old relationship with the United States is over.
Even if the U.S. forges a new trade agreement with Canada, Trump's erratic policy and the uncertainty of doing business with the U.S. will persist, according to interviews with more than a dozen companies, advisors, trade lawyers and associations.
