In 2006, the Canadian Government had appointed a Commission of Inquiry headed by former Supreme Court justice John Major to enquire into the crash of an aircraft of Air India named Kanishka on June 23,1985. The crash was caused by an explosive device suspected to have been planted in a piece of unaccompanied baggage by Sikh extremists belonging to the Babbar Khalsa headed by the late Talwinder Singh Parmar of Vancouver, Canada. The report of the Commission was released on June 17, 2010. The Commission has found that a "cascading series of errors" by the Government of Canada, the Royal Canadian Mounted Police and the Canadian Security Intelligence Service allowed the terrorist attack to take place.
