Trump ordered federal agencies to rename Lake Ontario as Lake America within 30 days.
Why it matters: The change is mostly symbolic because the lake straddles the U.S.-Canada border and Canadian usage is unlikely to change. But it adds another flashpoint to a worsening trade and messaging fight between Washington and Ottawa.
- Trump signed the executive order on Aug. 27, 2026, directing the Interior Department and the U.S. Board on Geographic Names to act within 30 days.
- The order applies to the federal U.S. geographic naming system, not to Canada.
- Trump linked the move to broader pressure on Canada, saying, "Canada's been ripping us off for a long time."
- Reuters reported Canadian officials said they would keep calling it Lake Ontario.
President Donald Trump signed an executive order on Aug. 27 directing the Interior Department and the U.S. Board on Geographic Names to rename Lake Ontario as Lake America in the federal naming system, according to the White House order.
The White House said the change is meant to align with Trump's earlier policy of restoring names that "honor American greatness." But the lake straddles the U.S.-Canada border, with New York to the south and east and Ontario to the north, west and southwest, so the practical effect is likely limited to U.S. federal usage.
AP reported Trump framed the rename as part of a broader pressure campaign on Canada in the trade dispute, saying Canada had been "ripping us off for a long time" on trade and military issues in its coverage.
The order follows Trump's earlier threat to make the change and echoes his move on the Gulf of Mexico, which he renamed the Gulf of America in federal usage on his second inauguration day, AP reported previously. Reuters reported Canadian officials dismissed the idea and said they would continue using Lake Ontario as the name.
The move lands against a backdrop of deteriorating U.S.-Canada relations after trade negotiations broke down and Ottawa said the old relationship would not return unchanged, AP reported last week.
By the numbers
- 30 days - White House deadline for implementing the rename in the federal naming system.
- Aug. 27, 2026 - Date Trump signed the executive order.
- 1 - Lake the order targets, Lake Ontario, a cross-border body of water.
Yes, but: The order does not change Canadian usage, and the White House language indicates it applies to U.S. federal naming systems only.
What's next: The Interior Department and U.S. Board on Geographic Names are directed to implement the change within 30 days.
