The premier of Ontario, Canada's most populous province, said on Friday he would call an early election, citing the need for a strong mandate to fight against tariffs threatened by U.S. President Donald Trump.

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.

Canadian leaders expressed relief that broad tariffs were not applied to Canadian products on the first day of Donald Trump’s presidency.
