WASHINGTON — President Donald Trump has signed an executive order renaming Lake Ontario as "Lake America" across federal geographic registries, intensifying diplomatic strains with Canada.

The designation strictly applies to how United States authorities identify the shared body of water. Canadian officials remain under no legal obligation to adopt the moniker, which closely follows Trump’s earlier move to rebrand the Gulf of Mexico.

The decree marks a sharp symbolic escalation as bilateral tensions continue to test traditional North American alliances.
