Canada plans retaliatory tariffs after US trade talks collapse

Canada plans to impose retaliatory tariffs on the United States after trade negotiations collapsed, following President Donald Trump's threat of 50 percent tariffs on Canadian vehicles, auto parts, and steel. Prime Minister Mark Carney accused the U.S. of trying to dismantle major Canadian industries and treat Canada as a subsidiary, while Ontario Premier Doug Ford signaled political unity, warning that cutting off electricity exports and critical minerals to the U.S. is possible. The escalating dispute marks a severe deterioration in U.S.-Canada relations, triggered after Canadian officials rejected demands they said threatened national sovereignty.
