The premier of Canada's most populous province is retaliating against President Donald Trump's harsh new tariffs against his country with a blanket ban on U.S. companies from receiving provincial contracts.

On Monday Doug Ford, the premier of Ontario, announced the new policy change on X, making clear that it would remain in effect as long as Trump's tariffs do.

"Every year, the Ontario government and its agencies spend $30 billion on procurement, alongside our $200 billion plan to build Ontario," wrote Ford, who leads the right-leaning Progressive Conservative Party of Ontario. "U.S.-based businesses will now lose out on tens of billions of dollars in new revenues. They only have President Trump to blame."

But Ford took it one step further, and singled out pro-Trump tech billionaire Elon Musk's SpaceX, which provides satellite internet services for the Ontario government. "We’ll be ripping up the province’s contract with Starlink," said Ford. "Ontario won’t do business with people hellbent on destroying our economy."

"Canada didn't start this fight with the U.S., but you better believe we're ready to win it," Ford concluded.
