Canada will respond immediately and forcefully if the United States goes ahead with a threat to impose tariffs, Prime Minister Justin Trudeau said on Friday, warning Canadians that they could be facing tough times.

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.

Prime Minister Justin Trudeau says if President Donald Trump wants to usher in a "golden age" for the United States, it will require more energy, critical minerals and resources that Canada is ready to provide.
