Outgoing Canadian Prime Minister Justin Trudeau says prices for Americans will go up if President Donald Trump follows through with his vow to apply sweeping tariffs on Canadian products.

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.

Speaking at a special cabinet meeting in Montebello on Tuesday, Quebec, Trudeau said that he was unfazed by Trump's about-face, saying he's come to expect a great deal of 'uncertainty' when dealing with this president.
