President-elect Donald Trump vowed Monday that on his first day in office he would impose a 25% tariff on all products coming into the United States from Canada and Mexico.

Donald Trump's proposed tariffs on Canada could increase U.S. gas prices by up to 70 cents a gallon, energy experts say.

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.
