U.S.-Canada tariffs could raise prices in both countries and test energy ties

The United States and Canada are moving toward a trade war that could raise prices on goods in both countries and strain American access to energy and allies. President Donald Trump has also floated renaming Lake Ontario as "Lake America" in a social media post. Canada announced tariffs of 15% to 50% on about $20 billion of American goods, including steel, aluminum, motorcycles, and processed cheese, effective Sept. 8. This responds to U.S. tariffs on Canadian products, with costs likely passed to consumers. Canada's economy is under 10% the size of America's, but officials have threatened to cut energy exports. Prime Minister Mark Carney frames the dispute as a test of resisting U.S. pressure, reflecting allies' growing view of Washington as unreliable.
