Conservative leader Pierre Poilievre is calling on Prime Minister Justin Trudeau to close an irregular border crossing within thirty days.

At a press conference on Tuesday, Poilievre called on Trudeau to close the Roxham Road border crossing between Quebec and New York state – a crossing which has gained media attention this month as reports grow about how migrants are using the crossing to illegally enter Canada.

“The prime minister has had six years to find a solution,” said Poilievre. “It is his job to close the border, and we’re calling on him to do it at the Roxham Road passage within thirty days.”

Quebec Premier Francois Legault last week called on Trudeau to publicly announce that migrants are no longer welcome. The premier called on Trudeau after media reports broke that New York City was bussing migrants near to the border crossing, purportedly to enable the migrants to cross into Canada.

Premier Legault reached out to American officials last week, attempting to find a solution to a legal loophole that encourages people to cross at places like Roxham Road.
