Ontario Premier Doug Ford has responded to US President Donald Trump by installing a massive shoreline sign declaring: "Lake Ontario. Now and Always."
The visual protest follows an executive order signed Thursday by President Trump seeking to rename the shared body of water "Lake America." Trump also posted AI-generated videos depicting himself kicking over a Lake Ontario sign, alongside clips of armed Canada geese sporting his signature hairstyle patrolling the shore.
"Long before President Trump, this lake was called Lake Ontario. Long after President Trump is gone, it will still be called Lake Ontario," Ford stated, adding that the US move stemmed from frustration over Canada asserting its sovereignty.
This rhetorical clash follows the breakdown of bilateral trade negotiations, after Washington levied 50% tariffs on 20 billion (C28bn) worth of Canadian exports. Ottawa has promised matching "dollar-for-dollar" counter-tariffs next month.
Canadian Prime Minister Mark Carney echoed Ford's stance, asserting that "things must be called by their name, and this lake is called Lake Ontario—today and forever."
While the US president holds executive authority over domestic geographic labels, foreign nations are under no obligation to comply. Mexico previously rejected a similar US attempt to rename the Gulf of Mexico, maintaining that a single country cannot unilaterally rename shared international waters.
Google announced on Saturday that it had updated Google Maps for US-based users to reflect official US Geographic Names Information System (GNIS) data:
"People using Maps in the US will see 'Lake America', those in Canada will continue to see 'Lake Ontario', and those outside both countries will see both names," the company confirmed.
The executive order grants the US Department of the Interior 30 days to update official domestic registries.
Lake Ontario—the smallest of the five Great Lakes bordering the Canadian province of Ontario and New York State—derives its name from Indigenous origins, alongside Lake Huron, Lake Michigan, and Lake Erie. Only Lake Superior takes its name from an anglicized French word.
