Trump considers renaming Lake Ontario Lake America
Trump linked a proposed new name for Lake Ontario to the worsening US-Canada trade dispute.

What happened
President Donald Trump wrote that he was seriously considering calling the shared US-Canada waterway Lake America. He linked the proposal to expectations of reduced business with Ontario after trade talks failed. The statement followed US tariffs on Canadian goods and Canada’s plan for equivalent retaliatory measures.
Numbers

- $20 billionCanadian goods facing US tariffs — After negotiations broke down
- 18,900 km²Lake Ontario’s approximate area — A shared Great Lake
Questions
- Who controls the lake’s name?
- Washington can change the geographic name used by federal agencies, but Canada and international bodies can continue using Lake Ontario.
- Why is the lake shared?
- It lies across the US-Canada border, with New York and Ontario governing their own lakebed and shoreline portions separately.
- Which sectors face tariff pressure?
- The measures target Canadian cars, trucks, auto parts and steel; Canada has stated it will answer with equivalent tariffs.
- What precedent does Trump cite?
- Last year, he ordered the Gulf of Mexico renamed Gulf of America for US federal government use.

Support and opposition
Who supports this, and why
US administration — Trade pressure is warranted after negotiations failed, and the United States expects less business with Ontario.
Who opposes this, and why
Canadian government — Equivalent counter-tariffs are needed to protect workers, farmers, families and businesses from new US tariffs.
The catch
No formal renaming order has been announced; a US-only change would not determine Canadian or international usage.
