TORONTO—Over the past 17 months, as President Trump has freighted Canada’s economy with several rounds of punishing tariffs, Prime Minister Mark Carney has often repeated the guiding maxim for his negotiations with the U.S.: No deal is better than a bad one.
Now he’s putting that rule to the test.
After nearly a month of trade negotiations aimed at staving off more U.S. tariffs on Canada, Carney walked away from a deal at the last minute on Friday night, allowing levies of 50% on $20 billion worth of Canadian goods to come into force.
