The widely shared image claiming a 17th-century map called Lake Ontario "Lac America" is altered. Archival copies of the 1688 map by Pierre Raffeix, held at the University of Toronto and the University of North Carolina, label the lake "Lac Ontario ou de Saint-Louis." The manipulated image circulated amid U.S.-Canada trade tensions and a presidential push to rename the lake. Multiple fact-checkers and academic sources have debunked the claim and highlighted the Indigenous origins of the name "Ontario."

After a surge of social media posts claimed a 17th-century French map labeled Lake Ontario as "Lac America," archival evidence shows the circulated image is manipulated. The authentic 1688 map by French missionary Pierre Raffeix, preserved in university collections, clearly names the body of water "Lac Ontario ou de Saint-Louis."
Reverse-image searches and archival copies held at the University of Toronto and the University of North Carolina confirm the original label. The altered image began appearing after a breakdown in U.S.–Canada trade talks and President Donald Trump’s August 27, 2026 executive order pushing to rename Lake Ontario "Lake America." The president and White House accounts have also shared other manipulated maps during the dispute.
Historical Context: French explorers and missionaries sometimes used "Saint Louis" as an alternate name, but the toponym "Ontario" is widely linked to Indigenous terms. Scholars and institutions commonly connect it to the Huron-Wyandot word "Ontarí:io," meaning "great lake" or "beautiful lake," and other Iroquoian roots have also been proposed. These origins predate both the United States and the Canadian confederation.
Fact-checking organizations including AFP, NewsGuard and Snopes have debunked the doctored map. Cultural institutions such as the Museum of Indigenous Peoples, as well as state cartography and environmental agencies, have provided archival evidence and historical explanations that contradict the online claims.
While political tensions over the proposed renaming have fueled the spread of manipulated images and misleading posts, archival records and historians provide clear evidence that no genuine historical map labeled the lake "Lac America."
