A war of words between the U.S. and Canada is heating up — as is the trade war between the longtime allies — with Ontario’s outspoken premier Doug Ford telling President Donald Trump twice he can “kiss my a–.”

On Monday, Trump pledged to raise the tariff on cars, steel and other goods to 50% in January. That followed tariffs of 50% on other goods being levied on Saturday after talks over a potential trade deal fell apart.

In a post on his social media account Monday morning, Trump said that Canada has been “ripping off the United States of America for years” and announced, “Tariffs on all Cars, Trucks, both large and small, Automotive Parts, and Steel, will be increased to 50%.”

“On Trade, and in other ways, also, they are among the worst Nations in the World to deal with. They feel entitled, and yet, WE DON’T NEED CANADA, THEY NEED US!” Trump added, despite the fact that the U.S. gets large quantities of oil, gas and other products from its neighbor to the north. 

Later on Monday, the Canadian Ministry of Finance said in a press release that several Canadian officials will visit a local business on Tuesday and hold a joint press conference “to announce new measures to protect and support Canadian workers and businesses during these challenging times.”

Canada’s CTV News reported the announcement would include retaliatory tariffs.

On Friday, Canadian Prime Minister Mark Carney announced that he was suspending trade negotiations with the U.S. after what he called “last-minute” changes were made to the proposed deal and vowed to retaliate “dollar for dollar” for any tariffs imposed. 

“However, last-minute changes in the U.S. proposed terms were unfair, uneconomic, and called into question the reliability of any deal.”

After the latest round of tariffs was announced, Carney said it was not a “surprise” and said the U.S. had to come to the negotiating table with the “right attitude,” not that Canada “is a subsidiary of the United States.”

“That’s not something we’re going to accept. And that’s before you get to constraints on our ability to do what the rest of the world wants, which is to sign trade deals, uh, with Canada,” he added during an event in Quebec.

Trump has long talked about making Canada the 51st state, something that Carney has rejected. 

Canadian premiers came to Carney’s defense, with Ontario’s Ford saying Canada will not “roll over” and British Columbia’s David Eby telling CNN “we have to hit back.”

During a radio appearance Monday morning, Ford suggested that Canada needed to “throw everything and the kitchen sink” at Trump, whom he called a bully. 

“He can kiss my a–,” Ford said.

Later in the day, Trump called out the “bluster” from Ford as well as Carney in a post on his social media, saying the U.S. “has been carrying Canada for decades, but no longer.”

“Someone should get these clowns to “fall in line” or, the consequences for Canada will be far WORSE!”

A short time later, Ford was asked about his comments on the radio and whether he had been asked to tone it down.

“I have a lot of real estate on my a–, so he has a lot of room to kiss my a–,” Ford said at a news conference, where he also called Trump a bully.

“I can go back and forth with Trump. You know, I’m not gonna. I’m just not gonna take the bait. This guy’s a loser. He’s going to be a loser,” he added. “And simple as that. We’re gonna fight with everything we have. And, uh, you know something? I have more courage, more brains in my baby toe than he has in his whole body. So, there you go.”
