Canadian Prime Minister Justin Trudeau said Friday that U.S. President-elect Donald Trump is serious about a threat to impose stiff import tariffs on Canadian imports and warned they would hurt both economies.

Prime Minister Justin Trudeau said that if President-elect Donald Trump follows through on this threat to impose tariffs on Canadian products, he would be raising prices and hurting American businesses.

The sudden visit to Florida by the leader of Canada comes days after Trump threatened to impose a 25 percent tariff on Canadian and Mexican goods.
