On 27 August 2026, President Donald Trump made headlines by signing an executive order that officially renamed Lake Ontario to “Lake America.” This announcement comes in conjunction with his earlier decision to change the name of the Gulf of Mexico to “Gulf of America.” During the signing ceremony in the Oval Office, Trump expressed sentiments suggesting he would not stop at rivers and lakes, hinting that he might also consider renaming the Atlantic and Pacific oceans.

“We have a gulf and we have a lake,” Trump told reporters. “Now all we need is an ocean. Maybe we’ll have to change the name of the Atlantic and/or the Pacific. Maybe we’ll change them both.” His remarks signal a desire to put a distinctly American stamp on geographical landmarks, reflecting a continued emphasis on national identity.
The decision to rename Lake Ontario follows a period of escalating tensions between the United States and Canada, particularly regarding trade and military cooperation. During the Oval Office address, Trump stated, “Canada has been ripping us off for a long time on trade,” indicating dissatisfaction with the current state of relations. He continued, asserting that Canada acts as if it should be treated like a U.S. state and expressed a clear unwillingness to continue that approach.
Before the formal signing of the executive order, Trump previewed his plans on social media. In a TikTok video released on 26 August, he introduced the new name for Lake Ontario, declaring, “We’re gonna call it Lake America. And all it takes is a good pen and some intelligence.” Demonstrating his point, he used a Sharpie to cross out the existing name and replace it with the new title, showcasing his characteristic penchant for theatrics.
The proposal arrives against a backdrop of deteriorating diplomatic relations. Recent trade negotiations between Washington and Ottawa have floundered, leading to increased tensions. Trump has been vocal about his dissatisfaction with Canadian leadership and has even threatened to impose a hefty 50% tariff on vehicles and automotive parts imported from Canada, set to take effect on 1 January 2027.
This latest initiative isn’t the president’s first foray into altering place names for the sake of national identity. Upon returning to office in January 2025, he made headlines when he announced the Gulf of Mexico would be renamed to the “Gulf of America,” stating, “It’s a beautiful name. That covers a lot of territory. The Gulf of America, what a beautiful name. And it’s appropriate.”
In addition to those changes, Trump’s tenure has also seen the reversion of Mount Denali’s name back to its former title, Mount McKinley. The Alaskan mountain’s name had been the subject of debate for many years, with its dual names honouring both the indigenous populations and Ohio-born President William McKinley. This alteration followed a 2015 decision during the Obama administration that had selected Denali as the official name.
While the U.S. government holds the authority to change names of places on national maps, experts point out that Trump cannot compel other nations or international organisations to adopt these changes. The proposed modifications can ultimately be viewed as personal declarations rather than universally recognised alterations.
As the country moves forward with these geopolitical manoeuvres, the president’s actions could have far-reaching implications, influencing not just domestic perceptions but also international perceptions of U.S. assertiveness. Whether these naming conventions will play a significant role in changing diplomatic relations, however, remains to be seen.
In the meantime, observers both in the U.S. and abroad will be watching closely to see how this bold move encourages – or challenges – the already complicated relationship with Canada and how it might resonate with Trump’s supporters who prioritise a strong sense of national identity.
