Former Prime Minister Justin Trudeau’s office allegedly “halted” a critical Canadian Security Intelligence Service (CSIS) foreign operation being carried out in partnership with allied nations.A heavily redacted National Security and Intelligence Review Agency (NSIRA) review released Thursday says the decision made from within the Prime Minister’s Office (PMO) “created unnecessary danger” for CSIS officers and “caused harm to Canada’s international reputation.” Policy adviser and former Liberal MP Dan McTeague used the word “treason” to describe Ottawa’s obstruction of the international operation. “This is TREASON,” he wrote on X..Inquiry reveals Trudeau warned 163 times about foreign interference.“The [REDACTED] story commences... when CSIS first learned of [information that required the planning of a specific category of operation]. CSIS started working with domestic and foreign partners [on an] operation involving [REDACTED],” states the review.The NSIRA said cancelling the high-risk operation was a “politicized act that placed Canadian operatives in immediate danger and inflicted lasting damage on the country’s international reputation and trust among intelligence partners,” wrote Sam Cooper of The Bureau in an analysis of the review..Sam Cooper on how 'Beijing picks its favourites' in Canadian elections — with the help of 'Trudeau Jr'.The review said the halt followed “political-level discussions” and “first came from the National Security and Intelligence Advisor to the Prime Minister to the Director of CSIS.”The CSIS Act requires recommendations such as this come first from the CSIS director or the public safety minister.However, the review indicates the chain of command on the decision to abandon the foreign operation came from the intelligence adviser, who serves at the pleasure of the prime minister and functions as part of the Privy Council Office (PCO).“NSIRA found that the decision to halt this active CSIS operation [REDACTED] was not made by the CSIS Director under section 6(1) of the CSIS Act, and for which there is no written record of a direction coming from the Minister of Public Safety under… the CSIS Act,” states the review..'Dismayed' Canadians petitioned China Inquiry for Parliament Hill spies to be named.Andrew Kirsch, former CSIS counterterrorism officer, posted an excerpt from the report on X, highlighting how “NSIRA’s review identified several significant concerns, including the appropriateness of direction given to CSIS by political-level actors outside the Minister of Public Safety.”.WATCH: Liberals perpetuate narrative Parliament Hill spies were Conservative .TREASON SCANDAL: MPs uneasy over unnamed spies operating on Parliament Hill .“Moreover, [REDACTED] to halt this active operation created unnecessary danger for the CSIS team [REDACTED] and caused harm to Canada’s international reputation,” states the review.“The CSIS team told NSIRA that they felt abandoned and, they believed that the absence of a Government decision ‘was a decision.’ Facing this untenable situation, the CSIS team felt forced to plan alternative actions to help ensure [their own] safety.”“The review revealed that CSIS senior officials had difficulty in grappling with [REDACTED] to halt the operation; so much so, in fact, that management and control of the operation appeared to cease functioning properly.”“The Director of CSIS, for instance, evidently no longer had decision-making control over the active operation, when on [REDACTED] he sent an email to senior officials within key security and intelligence portfolios stating: ‘time is quickly running out and the situation is getting much more tense on the ground. We need a decision tomorrow.’”
