Lake Ontario will now be known as Lake America once Trump signs an order. – WASHINGTON — In the midst of a fast intensifying trade dispute with Canada, President Donald Trump threatened to rename Lake Ontario as Lake America for days before signing an executive order directing his department to do so.
On August 27, Trump signed an order in the Oval Office directing the U.S. Board on Geographic Names and the Department of Interior to finalize the change within 30 days. Trump likened the decision to renaming the Gulf of Mexico the Gulf of America last year when he signed the decree.We already have a lake and a gulf, so all we need now is an ocean,” Trump remarked. “So maybe we’ll have to change the name of the Atlantic and/or the Pacific.”
The native Iroquois tribe’s phrase “Ontarí’io,” which means “lake of shining waters,” is where Lake Ontario got its name in the 17th century, according to the Center for Great Lakes Literacy. In the 1660s, the term began to show up on maps of European explorers.
As Trump signed the order, a posterboard featuring a map of the Great Lakes and the phrase “Making the Great Lakes Greater” was placed on an easel beside him.
Trump was informed by White House staff secretary Ben Moss that the order guaranties that the “lake once known as Lake Ontario will from this day forward be known as Lake America.” The majority of the lake’s volume, including its deepest portions, is in U.S. jurisdiction, according to Moss, despite the fact that Lake Ontario forms the shoreline of Toronto, the largest city in Canada.As he gave the president the order to sign, Moss remarked, “This will reflect that this is an American lake.”
Trump’s renaming of the lake comes after he imposed broad 50% tariffs on numerous Canadian items following the collapse of trade talks between the two nations last week. In response, Canadian Prime Minister Mark Carney imposed tariffs ranging from 15% to 50% on U.S. exports. Additionally, Trump has threatened to raise tariffs on Canadian cars and auto parts from 25% to 50%.We have been mistreated by Canadian officials. “They’re nasty people,” Trump declared, accusing Canada of levying high taxes on goods produced by American farmers.
Lake Ontario is still known as “then, now, and always,” according to Carney.
The U.S. Board on Geographic Names, which is composed of officials from various government agencies, is in charge of naming lakes, rivers, and other geographical features in the country. The president’s renaming of the Gulf of Mexico accelerated the official review procedure that usually surrounds name changes.
The directive directs the board and Interior Secretary Doug Burgum to update the Geographic Names Information System (GNIS) with Lake Ontario’s new name, Lake America. The renaming must be reflected in all federal government references to the lake, including contracts, agency maps, and other documents.
In a statement released after Trump’s decree, Carney stated that despite Trump’s action, the lake will always be known to Canadians as Lake Ontario.The name predates both the United States of America’s Declaration of Independence and the Confederation of Canada by more than 400 years, according to Carney. “We are aware that America is evolving. Their economic links, their foreign policy, their national monuments, their hydronyms. Additionally, Canadians understand that naming reality entails referring to it as Lake Ontario—then, now, and forever.
The rest of the globe is unlikely to adopt Trump’s rebranding as well.
The international community, including Mexico, still refers to the body of water as the Gulf of Mexico rather than the Gulf of America, even after Trump rebranded it last year.
