The leader of Ontario said he will be calling an election next week because he needs a mandate to fight Trump's threatened tariffs.

While much about the threatened tariffs is still unclear, experts predict they would be bad news for all three economies, with few winners.

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.
