Donald Trump says he’s not “doing much business with Ontario” anymore amid Lake Ontario rename

On Tuesday, President Trump announced in a Truth Social post that he is weighing renaming Lake Ontario as “Lake America,” attributing the idea to the strained commercial relationship with Canada. The statement came after U.S.-Canadian trade negotiations broke down Friday and the administration imposed 50 percent tariffs on about $20 billion of Canadian goods, from automobiles and steel to dairy and alcohol. Prime Minister Mark Carney labeled the action unfair and pledged equivalent retaliatory tariffs, with details expected in September. Ontario Premier Doug Ford has threatened responses such as cutting electricity or critical mineral exports. The lake is governed through shared U.S.-Canadian agreements, so a rename would face legal obstacles. Meanwhile, businesses on both sides worry about higher prices and disrupted supply chains.
