Prime Minister Justin Trudeau has made a surprise trip to Florida to meet with Donald Trump, in the wake of the U.S. president-elect's threat to impose a 25 per cent tariff on all Canadian goods entering the U.

The unannounced meeting comes days after President-elect pledged to enact crippling tariffs on Canada and Mexico over illegal immigration and drugs.

Canadian Prime Minister Justin Trudeau flew to Florida and met with Donald Trump at his Mar-a-Lago club on Friday evening, less than a week after the U.S. president-elect threatened heavy tariffs on imports from North American trading partners.
