Trump has threatened to impose 25 per cent tariffs on all Canadian goods coming into the U.S. But his threat has raised questions as to whether Canada has any kind of leverage to squeeze the U.S. and prevent such tariff action.

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.

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.
