Ontario Premier Doug Ford called Donald Trump a bully and said he can “kiss my ass” as the U.S.-Canada trade war continues.

Trump imposed 50% tariffs on $20 billion worth of Canadian products early Saturday, and Canadian Prime Minister Mark Carney immediately said Canada would retaliate after last-ditch negotiations failed to resolve the latest Trump-initiated feud.

Trump escalated the feud on Truth Social Monday, accusing Canada of “ripping off” the United States, and declaring, “WE DON’T NEED CANADA, THEY NEED US!”

Trump added that he will increase tariffs on “all Cars, Trucks, both large and small, Automotive Parts, and Steel” to 50 per cent on Jan. 1, 2027.

Ford fired back in an interview with CTV, saying Trump “can kiss my ass as far as I’m concerned.”

“We are gonna go at him full steam,” Ford continued.  “We need to throw everything and the kitchen sink at him. He’s arrogant, he’s cocky, and you know — as Ronald Reagan said — if you come to a draw with a bully, what stops that bully from coming at you the next day, and the next day? And that’s all Donald Trump is: a bully. He’s gonna have a rude awakening.”

Ford also threatened to cut off electricity to U.S. facilities.

“He might as well call up the Energizer Bunny, because he should be powering his facilities,” Ford said.

The latest tit-for-tat tariff battle comes after negotiations between the two former close allies collapsed in Washington on Friday.

Carney accused Washington of using “economic integration as a weapon” and said “its signature was written in pencil,” The Associated Press reported. Carney added that he told Canadian negotiators to walk away.

But to Trump’s chief trade negotiator, Jamieson Greer, the U.S. took these drastic measures in response to a year of retaliation by Canada.

“We’ve said enough, and so we’ve taken countermeasures. Our interest is in protecting American workers and protecting American supply chains,” the U.S. trade representative told ”Fox & Friends Weekend.”
