A truck crosses into the United States from Canada on the Gordie Howe International Bridge, connecting Windsor, Ontario, and Detroit, Michigan, on September 6, 2026. Canada announced on August 25, 2026 counter-tariffs on US goods ranging between 15 and 50 percent, intensifying the trade war between the historically close allies.
