"They feel entitled and we can’t have that," Trump stated, criticizing Canada’s trade practices.
The executive order, signed at the Resolute Desk, directs the U.S. Department of the Interior to update the Geographic Names Information Service to reflect the change.
This decision comes after the U.S. imposed new 50% tariffs on $20 billion worth of Canadian goods, prompting Canada to retaliate with equivalent tariffs.56

"The move is official, effective immediately," Trump declared, emphasizing that his administration has completed all necessary paperwork.
The name change is reminiscent of his previous order to rename the Gulf of Mexico to the Gulf of America, which was similarly rejected by Mexico.
Trump hinted that he may pursue further name changes, suggesting, "So maybe we’ll have to change the name of the Atlantic and or the Pacific. Maybe we’ll change them."
Despite Trump's actions, Canada has stated it will continue to refer to the lake as Lake Ontario, highlighting the complexities of international naming conventions and the ongoing trade dispute between the two nations.
