Canada weighs cutting power exports to US in tariff fight

Canada may cut or raise prices on power exports to the U.S. in retaliation for President Trump's new tariffs, potentially increasing costs for American consumers in northern border states like New York. Prime Minister Mark Carney vowed "dollar for dollar" measures, while Ontario Premier Doug Ford said cutting electricity to 1.5 million U.S. homes is an option. Trump announced 50% tariffs on Canadian cars, aluminum, and steel, effective Jan. 1, after talks collapsed Friday. Canada will release a list of affected American goods after Labor Day. The trade war threatens Republican midterm prospects, as tariffs remain unpopular with voters in battleground states like Michigan and Maine.
