Canada imposes retaliatory tariffs on US goods as Trump bans Canadian imports

The trade war between the United States and Canada has escalated sharply. Following the implementation of Canada's retaliatory tariffs on $20 billion of American goods, President Donald Trump signed orders banning Canadian dairy, alcohol, and motorcycle imports starting September 29, 2026. Trump also moved to block Canadian firms from federal contracts and threatened Bombardier aircraft sales. Canadian Prime Minister Mark Carney has pledged to accelerate efforts to diversify trade away from the U.S., while domestic polls show rising support for his defiant stance despite the economic risks.
