Ontario Premier Doug Ford has unveiled a new Lake Ontario sign Saturday afternoon, just days after Donald Trump renamed the Great Lake as “Lake America.”

Ford’s appearance in Winona, Ont., came as Canada-U.S. trade tensions continue to escalate, with the premier using the name change to reinforce his message that Ontario will “never back down” and always defend its interests.

“President Trump can call it whatever, but I can tell you the rest of the world will always call it Lake Ontario,” Ford said.
