Ontario threatens to cut power to 1.5 million US homes over tariffs

Ontario Premier Doug Ford threatened to cut electricity exports to the US, potentially affecting 1.5 million American households, in response to escalating trade tariffs. Ford stated he would halt power sales but requires a coordinated approach with other Canadian provinces. The threat comes amid a full-scale trade war between Canada and the US, with Washington imposing 50% tariffs on roughly $20 billion worth of Canadian goods. Canada's Prime Minister Mark Carney called the action a "direct attack" and announced retaliatory tariffs starting September 8. US tariffs target about 5% of Canadian exports, including honey, seeds, cosmetics, clothing, and furniture. Ontario's electricity systems are integrated with northern US states, enabling continuous cross-border power flow.
