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.

Canadian Prime Minister Trudeau flew to Trump's Florida home after the president-elect's threat to impose significant tariffs on Canada and Mexico.

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.
