President Donald Trump has suggested he is considering renaming Lake Ontario to “Lake America,” a move that echoes his earlier executive order to rebrand the Gulf of Mexico as the Gulf of America. The proposal, floated on social media on Tuesday, comes as the trade dispute between the United States and Canada escalates, with Ottawa expected to unveil countermeasures later in the day.
“The United States is giving serious consideration to changing the name of Lake Ontario to Lake America in that we don’t expect to doing much business with Ontario any longer,” Trump wrote, referring to Canada’s most populous province, which hosts much of the country’s automotive manufacturing.
The rhetorical sparring has intensified. On Monday, Trump told Canadian leaders to “fall in line” or face consequences “far WORSE” than the existing tariffs. His administration has already imposed 50% duties on $20 billion (€17 billion) of Canadian goods after talks broke down over the weekend, and he has threatened further tariffs on Canadian vehicles, auto parts, and steel.
Canadian Prime Minister Mark Carney has responded sharply, accusing Washington of trying to subordinate Canada. “An attitude at the negotiation table that Canada is a subsidiary of the United States is not something we’re going to accept,” Carney said. In French, he was even more blunt: “We learned during the negotiations that the Americans want to destroy our major industries, including autos, steel and aluminium. That was one of the main reasons we said no. It was a bad deal.”
Economic interdependence at risk
The two countries share one of the world’s largest trading relationships, with deeply integrated supply chains spanning cars, energy, agriculture, and manufacturing. A prolonged trade fight could prove costly for businesses and workers on both sides of the border, as well as for consumers facing price uncertainty.
Michael Howard II, who runs a furniture business in Warren, Michigan, near Detroit, said the tariffs will hamper “the ability for us to put food on the table for our family, but also impacts the ability for us to give back to our community.” Howard and his wife started their company a decade ago, making everything from dining room tables to bookcases. “To say that we don’t need Canada is just disingenuous,” he said. “It’s dishonest. And it’s just absolutely not truthful. We need our neighbour, but also they need us.”
Canada’s Finance Minister François-Philippe Champagne and three other cabinet ministers are expected to outline support measures for workers affected by the tariffs. Carney has suggested that Canada may shift away from matching US tariffs dollar-for-dollar and instead adopt more targeted retaliation aimed at protecting Canadian workers and businesses.
The dispute has broader implications beyond North America. As a key partner in the G7 and a member of NATO, Canada’s stance is being watched closely in European capitals, where officials are assessing the reliability of US trade policy. The escalating rhetoric and the threat of further tariffs have raised concerns about the stability of transatlantic economic relations, particularly for European companies with supply chains that cross the Atlantic.
For now, the immediate focus remains on the next round of retaliation from Ottawa and whether the two governments can find a path back to negotiations. The name of a lake may be a symbolic gesture, but it underscores the depth of the rift between two longtime allies.
