Canadian Prime Minister Mark Carney announced retaliatory tariffs on U.S. goods following the collapse of trade negotiations in Washington on August 21, 2026.
The U.S. had previously imposed 50% tariffs on $20 billion worth of Canadian goods, representing 5.5% of Canada's total exports to the United States.
Canada's new measures, which target U.S. steel and dairy industries, are scheduled to take effect on September 8, 2026, amid a deepening rift between the two nations.
