Mark Carney, on Lake America rename, says lake's name means "the lake is beautiful, the lake is big"

President Donald Trump signed an executive order Thursday to rename Lake Ontario as "Lake America" in U.S. federal records, a change affecting American government maps and documents. Canadian leaders, including Prime Minister Mark Carney, said they will not accept the new designation. Carney noted the lake's name has Indigenous roots in the Wendat language and predates both countries. Mississaugas of the Credit First Nation Chief Margaret Sault said the lake remains part of her nation's ancient homeland and that such a renaming cannot erase its history. The dispute highlights sharply different views between the U.S. and Canada over a shared body of water.
