Ontario Premier Doug Ford told U.S. President Donald Trump he could "kiss my ass" during a radio interview in Ontario [1].

The exchange signals a sharp escalation in tensions between Canada and the U.S. as a trade deal between the two nations collapses.

Ford made the remarks during a 45-minute interview [2] after Trump threatened to impose new tariffs on cars and trucks. The premier said the proposed trade agreement was a "bad deal" for Ontario [3].

Ford did not stop at the initial insult. He said the U.S. president was a "loser" [4] and a "dictator" [5].

The automotive sector is a cornerstone of Ontario's economy, making the threat of vehicle tariffs a critical issue for the provincial government. Ford's rhetoric marks a significant departure from traditional diplomatic communication between Canadian provincial leaders and U.S. federal officials.

Trump had previously lashed out at Ford, calling him a "flunky" [6]. The public exchange follows a period of increasing bad blood as the trade war spills over into personal insults between the two leaders [7].

Ford renewed his comments in response to the ongoing trade dispute, maintaining his stance against the U.S. administration's approach to tariffs [3].

"Trump can kiss my ass."

The breakdown in diplomatic decorum between Ontario and the U.S. executive branch reflects the high stakes of the automotive trade war. Because Ontario relies heavily on vehicle exports to the U.S., the premier's aggressive posture suggests a strategy of public defiance to signal that the province will not accept terms it views as detrimental to its economic stability.
