Trump said in Washington that it was time to teach Canada you cannot do this anymore after trade talks between the two countries broke down. He said he had offered a good deal and argued the United States can get what it needs elsewhere. The dispute escalated after the United States imposed new 50 percent tariffs on $20 billion of Canadian imports and Canada responded with retaliatory tariffs. Trump also announced 50 percent tariffs on Canadian autos and parts to take effect on January 1.
