US President Donald Trump suggested renaming Lake Ontario to "Lake America" in a Truth Social post, citing strained relations with Canada amid trade tensions. The threat is reminiscent of his previous attempt to rename the Gulf of Mexico to "Gulf of America", which only applied to US federal usage. A 1989 agreement between the two nations emphasizes using consistent names for shared geographical features, but allows for name changes due to local preference or special requests. Trump's comment comes after trade talks broke down and both countries imposed tariffs on each other's goods.
