The U.S. changed its own federal usage, but Canada and the international community did not universally rename Lake Ontario.
The naming order has effect within U.S. federal usage. It does not give the United States unilateral authority to determine what Canada or every other country calls the shared lake.

Fact check: The U.S. adopted 'Lake America' for federal usage, but Lake Ontario was not universally renamed for Canada or the world.
Lake America Lake Ontario renamed executive order Google Maps Apple Maps
A U.S. executive order directed U.S. federal agencies to use 'Lake America,' and some U.S.-facing digital maps adopted that label. That did not rename the lake for Canada or establish a universal international name change.
The U.S. federal government genuinely adopted 'Lake America' for its own official usage, and major mapping platforms reflected that designation for some users.
A domestic U.S. naming decision is being presented as though it changed the lake's name everywhere. Canada continues to use Lake Ontario, and the lake remains shared international geography.
Lake Ontario is shared by Canada and the United States. Claims that it has been universally renamed blur the difference between U.S. federal naming practices and the lake's legal, geographic, and cultural status in Canada.
Short answer
The U.S. genuinely changed its own federal usage to “Lake America.” That did not universally rename Lake Ontario for Canada or the rest of the world.
What's true
U.S. federal agencies adopted the new label, and some digital maps reflected it for U.S. users.
What's wrong or missing
A domestic U.S. designation is not the same thing as an international or Canadian name change.
What the evidence shows
Canada continues to use Lake Ontario, and the lake remains shared international geography. The U.S. order governs U.S. federal naming practice, not universal usage.
