OTTAWA—Canadian Prime Minister Justin Trudeau warned President Trump that his renewed pledge to impose a 25% tariff on all Canadian imports, starting as early as Feb. 1, risks derailing his effort to usher in a “golden age” for America,

Trump said in an Oval Office signing ceremony on Monday that his administration will impose a 25% tax on goods from Canada and Mexico that may come as soon as February 1 – a move that could raise prices for American consumers.

Canada’s outgoing prime minister and the leader of the country’s oil rich province of Alberta are confident Canada can avoid the 25% tariffs President Donald Trump says he will impose on Canada and Mexico on Feb.
