The United States and Canada have plunged into an intense trade war after the collapse of last-ditch negotiations in Washington. Following a 50% US tariff on $20 billion of Canadian goods, Canadian Prime Minister Mark Carney announced matching dollar-for-dollar retaliatory tariffs on $20 billion of US imports, effective September 8, 2026. To cushion the economic blow, Ottawa unveiled a C$7.5 billion support package for affected businesses and workers. Tensions continue to rise as President Donald Trump threatens further auto tariffs and Ontario Premier Doug Ford warns of cutting off electricity and critical minerals.
