Canadian Prime Minister Justin Trudeau is revising the nation’s immigration policies, particularly the migrant worker program, in response to growing domestic criticism and diplomatic tensions with the United States.

The U.S. has increasingly pressured Canada to curb the number of migrant workers crossing into its territory, citing one of the world’s most open immigration systems as a concern, as reported by the Financial Times.

“U.S. lawmakers are pushing for stronger northern border security due to concerns over illegal migration from Canada,” said Glenn Cowan, CEO of security firm One9, in an interview with the Financial Times. “Reducing these visa flows could strengthen U.S.-Canada relations.”

These developments come as Trudeau, who once championed Canada’s open migration policies, now faces rising domestic opposition. With an election looming and slipping poll numbers, Trudeau recently stated that his government is “reviewing various immigration channels to ensure that Canada continues to be a welcoming nation while responsibly integrating newcomers.”

Conservative Party leader Pierre Poilievre has criticised Trudeau, claiming that his policies are undermining Canada’s immigration system and advocating for a more controlled population growth strategy moving forward.
