CORRECTION: An earlier version of this report misstated the day President-elect Donald Trump threatened tariffs on Mexico, Canada and China.  President-elect Donald Trump has already begun to captivate financial markets with his unorthodox negotiating style,

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 said that he would impose the across-the-board tariffs on Day 1 and that they would stay in place until Canada, Mexico and China halted the flow of drugs and migrants.
