CSIS Calls Air India Flight 182 Bombing Canada's Deadliest Terrorist Attack, Names Canada-Based Separatists

More than four decades after the Air India Flight 182 "Kanishka" bombing, Canada's intelligence agency, the Canadian Security Intelligence Service (CSIS), has officially acknowledged for the first time that the June 23, 1985 attack was carried out by Canada-based Khalistani extremists. The bombing of Air India Flight 182 claimed the lives of all 329 passengers and crew members on board, the majority of whom were Canadian citizens. In an official statement, CSIS said that a bomb planted by Canada-based Khalistani separatists destroyed the aircraft, resulting in the deaths of everyone on board. The agency described the incident as the deadliest terrorist attack in Canadian history. The statement is being viewed as a significant development because, for decades, official Canadian statements generally avoided directly identifying those responsible for the attack. India has long maintained that Khalistani extremist elements were behind the bombing, and many analysts believe the latest CSIS statement reinforces that position. CSIS also highlighted the issue in its 2025 public report, stating that Canada-based Khalistani violent extremists (CBKEs) continue to pose a threat to Canada's national security and Canadian interests. The report draws a clear distinction between peaceful advocacy for Khalistan and violent extremism, noting that only individuals or groups involved in violence, fundraising for extremist activities, or other forms of terrorism are considered extremist threats. The Air India Flight 182 "Kanishka" bombing remains one of the darkest chapters in the shared history of Canada and India. Forty-one years after the tragedy, CSIS's explicit acknowledgment is expected to hold significance not only for the victims' families but also for ongoing discussions in Canada regarding extremism, violent radicalization, and national security.
