Billionaire Elon Musk is calling Prime Minister Justin Trudeau “an insufferable tool” in a new social media post on Wednesday.

“Won’t be in power for much longer,” Musk also wrote about the prime minister on “X.”

Musk was responding to a video posted of Trudeau, in which the prime minister described Kamala Harris’ U.S. presidential loss as a setback for women’s progress.

“We were supposed to be on a steady, if difficult sometimes, march towards progress. And yet, just a few weeks ago, the United States voted for a second time to not elect its first woman president, Trudeau said during a speech at the Equal Voice Foundation Gala in Ottawa on Tuesday night.

Trudeau also said women’s rights and women’s progress are “under attack overtly and subtlety,” and that he “always will be a proud feminist.”

Musk, who is the CEO of Tesla and founder of space company SpaceX, has been tasked to co-chair U.S. president-elect Donald Trump’s new Department of Government Efficiency. He was also a prominent figure in Trump’s election campaign.

Wednesday’s post is Musk’s latest swipe at the prime minister since Trump was re-elected in November. Responding to a user on “X” on Nov. 7 asking for Musk’s help to get rid of Trudeau, Musk wrote “He will be gone in the upcoming election.”

Ontario Premier Doug Ford says he let Trudeau know his comments were “not helpful.”

Ford, who with the rest of Canada’s premiers, met with the prime minister and several of his cabinet ministers on Wednesday to discuss how Canada would respond to Trump’s tariff threats.

“Donald Trump was elected democratically,” Ford said, adding that the premiers made sure Trudeau “got the message loud and clear.”  

Musk’s post also comes during a tense time in Canada-U.S. relations.

Trudeau has been facing social media jabs from Trump following the prime minister’s visit to Mar-a-Lago nearly two weeks ago to discuss Trump’s tariff threat. Last month, Trump threatened to impose a 25 per cent tariff on all Canadian imports on his first day in office unless Canada addresses his border security concerns.

Following that meeting, U.S. network Fox News reported Trump joked during the dinner in Florida that if the potential tariffs would harm the Canadian economy — as the prime minister conveyed to him — perhaps Canada should become Americas 51st state .

Days later, Trump posted an A.I.-generated image to social media that depicted him standing next to a Canadian flag  and overlooking a mountain range with the caption “Oh Canada!”

In an interview on Sunday with NBC’s Meet The Press, Trump made another reference to Canada becoming a state.

Were subsidizing Canada to the tune over $100 billion a year. Were subsidizing Mexico for almost $300 billion. We shouldnt be — why are we subsidizing these countries? Trump said to NBC News. If were going to subsidize them, let them become a state.

And just yesterday, Trump appeared to be mocking Trudeau, calling him “Governor Justin Trudeau ” in a post on Truth Social.

It was a pleasure to have dinner the other night with Governor Justin Trudeau of the Great State of Canada. I look forward to seeing the Governor again soon so that we may continue our in depth talks on Tariffs and Trade, the results of which will be truly spectacular for all! Trump wrote.

This week, Trudeau said Canada “will respond” if the U.S. moves ahead with a 25 per cent tariff. The federal government also says it will be adding more personnel and equipment resources, and show more visibility at the border  in the wake of the tariff threat.
