Trudeau says government monitoring after CSIS reports Iran has issued death threats against Canadians

Prime Minister Justin Trudeau says he's aware of reports that Iranians are "interfering" with the lives of Canadians and his government is monitoring the threats.

CBC News reported Friday that Canada's spy agency is investigating what it calls multiple "credible" death threats from Iran aimed at individuals in Canada. The Canadian Security Intelligence Service (CSIS) said the threats undermine Canadians' safety and it is working with allies to respond.

"We are constantly watching and evaluating the threats posed to Canadians from foreign interference from a range of countries," Trudeau said at the Francophonie Summit in Djerba, Tunisia on Sunday.

"But obviously Iran is a significant concern these days, with not just the extraordinary heroics of women and girls in Iran standing up to the regime … We also know there are significant concerns about Iranians interfering with the wellbeing of Canadian citizens here in Canada."

Trudeau pointed out that the federal government announced a series of sanctions in recent weeks to ban Iran's leaders — including officials in the Islamic Revolutionary Guard Corps — from entering Canada. He said the goal is to ensure they can "never benefit from Canada, interfere in Canada or consider Canada a safe haven."

Reports of death threats come as Iran enters its third month of anti-government demonstrations triggered by the death of 22-year-old Mahsa Amini, who was arrested by the so-called morality police and died in custody after allegedly wearing her hijab improperly. At least 341 people — including teenagers and children — have been killed and more than 15,800 have been detained in relation to Iran's protests, according to Human Rights Activists News Agency, an organization of Iranian activists. Experts suggest the true numbers could be much higher, given the regime's crackdown on the release of real-time information online.

Iran has kidnapped and assassinated activists, journalists and intellectuals abroad who speak out against the regime. Between 1988 to 1988, dozens of prominent Iranian dissidents abroad went missing or were killed.

Shahrooz is an Iranian-Canadian who is an outspoken critic of Iran's regime. He was one of the organizers of a large anti-government protest last month in Richmond Hill, Ont. Police estimated more than 50,000 people attended.

He said Canadian authorities have not told him if he's a target and hopes people are being warned they could be in danger. 

"It is deeply frightening that it's happening in Canada and may be happening to people I know," said Shahrooz, who is also a senior fellow at the Macdonald-Laurier Institute.
