Trade relations between the US and Canada deteriorate as the US imposes 50% tariffs on $20 billion of Canadian goods following the collapse of negotiations. Canadian Prime Minister Mark Carney rejects the US terms as unacceptable and announces dollar-for-dollar retaliatory tariffs on US steel, dairy, and electronics starting September 8, 2026. US Trade Representative Jamieson Greer defends the measures to protect American workers, casting doubt on the future of the USMCA.
