Executive Order Officially Renames Lake Ontario to Lake America
U.S. President Donald Trump signed an executive order officially renaming Lake Ontario to Lake America.
The decision comes after weeks of deteriorating U.S.–Canada trade talks, which concluded with the imposition of new 50% tariffs on approximately $20 billion (C$28 billion) of Canadian goods. In retaliation, Canada has indicated it will implement “dollar‑for‑dollar” counter‑tariffs next month.
President Trump has publicly promoted the renaming several times via social media during the dispute. He confirmed on Thursday that the move is “official, effective immediately” and that his administration had submitted all requisite legal documentation to effect the change.
Canadian Prime Minister Mark Carney emphasized that the name Lake Ontario enjoys a legacy stretching back over four centuries. In a related social media statement published earlier that day—the context preceding Canada’s own confederation and the signing of the U.S. Declaration of Independence—Carney remarked:
“We know that the United States is changing. Their trade relations, their foreign policy, their national monuments, their hydronyms,” Carney wrote online. “Canadian citizens recognize that places must have enduring names, and today we affirm that this lake shall henceforth be known as Lake America.”
Notably, the 2025 transition echoed a prior similar move enacted when President Trump previously renamed the Gulf of Mexico to the Gulf of America. Mexico rejected the unilateral naming adjustment, sparking diplomatic friction and a legal clash involving technology firm Google, which altered its mapping labels without U.S. approval. While Mexican users continue to navigate the dispute, Google initially faced restrictions preventing journalists from accessing exclusive events hosted by the White House under the new terminology.
