- The Premier of Ontario, Doug Ford, has unveiled a giant 5.5-metre high sign to reaffirm the lake’s historic name.
- This initiative is a response to an executive order by US President Donald Trump renaming the body of water « Lake America » for US government agencies.
- This symbolic conflict comes amid sharp trade and tariff tensions between Ottawa and Washington.
A symbolic response at the Canadian border

The government of the Canadian province of Ontario has reacted spectacularly to Washington’s latest unilateral decision. On Saturday, 29 August, Provincial Premier Doug Ford unveiled a massive billboard near the town of Grimsby, bearing the bilingual message « Lake Ontario. Today and forever ». This imposing structure, over five metres high, was erected in direct response to a US presidential executive order signed two days earlier. On Thursday, 27 August, Donald Trump ordered all US federal agencies to replace the historic name of Lake Ontario with « Lake America » in all their official documents, maps, and contracts.
Limited repercussions amid a trade crisis
In legal terms, the American measure remains confined within the borders of the federal administration in Washington and does not affect Canadian sovereignty or cartography. However, it illustrates the deep freeze in diplomatic relations between the two North American neighbours, currently locked in a major tariff dispute following the failure of trade negotiations. While Ottawa denounces a decision that denies the centuries-old history of this name of Indigenous origin, provincial authorities claim to have received support from several US governors determined to ignore the presidential directive. This standoff follows a method already tested by the US president, who had previously renamed the Gulf of Mexico as the « Gulf of America » for his administration by executive order.
