A Pakistani man arrested in Quebec as he was allegedly on his way to New York to conduct a mass shooting at a Jewish centre entered Canada last year on a student visa, Immigration Minister Marc Miller said Tuesday. Muhammad Shahzeb Khan, charged last week in an ISIS terrorism plot, received a student visa in May 2023 and arrived at Toronto’s Pearson airport on June 24, 2023, the minister told reporters. Miller also said it was “highly careless” of the Conservatives “to be firing their mouths off again” about Khan, and that Opposition Leader Pierre Poilievre’s advisors “should be counselling him to shut his mouth.”
