Outgoing Canadian Prime Minister Justin Trudeau said Thursday American consumers will pay more whenever President Donald Trump decides 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.

The outgoing PM said Trump is a “skilled negotiator and will do what he can to keep his negotiating partners a little off balance.”
