Canadian Prime Minister Justin Trudeau is returning home after his meeting with Donald Trump without assurances the president-elect will back away from threatened tariffs on all products from the major American trading partner.

President-elect Trump and Canadian Prime Minister Justin Trudeau met Friday night at Trump’s Mar-a-Lago home to discuss U.S.-Canada relations, as Trump threatens to impose hefty tariffs on both Canada and Mexico.

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.

A government official says Canada is already examining possible retaliatory tariffs on certain items from the United States should President-elect Donald Trump follow through on his threat to impose sweeping tariffs on Canadian products.

The president-elect’s opening salvo in trade and border talks with the United States’ neighbors is casting a harsh light on the North American alliance.

Canadian Prime Minister Justin Trudeau reportedly met with President-elect Trump at Mar-a-Lago Friday evening, in the wake of the former president’s recent threats to impose steep tariffs on goods from Canada,

Trudeau flew to Florida on Friday evening and had dinner with Trump at his Mar-a-Lago residence, days after Republican Trump had pledged to impose tariffs on Canadian and Mexican imports after he is sworn in as president in January.

President-elect Donald Trump said that his meeting at Mar-a-Lago with Canadian Prime Minister Justin Trudeau was “productive,” but made no mention of backing off his tariff threat.

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