Donald Trump says Canada "lives because of the United States" amid tariff row

Canada has imposed tariffs on about $20 billion in U.S. imports, with rates of 15, 25, or 50 percent on hundreds of products, in retaliation for Washington’s latest trade duties. The escalation follows the breakup of bilateral talks in late August and a series of U.S. threats, including possible penalties on Canadian vehicles and Bombardier aircraft. Prime Minister Mark Carney warned in Davos that powerful countries use economic integration to pressure smaller ones; President Donald Trump replied the next day with a harsh message to Carney. The confrontation has boosted Carney’s domestic support, analysts say, and he will address the European Parliament next week. World leaders are watching to see whether Canada can resist U.S. pressure successfully.
