The provisions of the '' Canadian Transportation Accident Investigation and Safety Board Act '' were written to establish an independent relationship between the TSB and the Government of Canada . This agency 's first major test came with the crash of Swissair Flight 111 on September 2 , 1998 , the largest single aviation accident on Canadian territory since the 1985 crash of Arrow Air Flight 1285 . The TSB delivered its report on the accident on March 27 , 2003 , some 4 ½ years after the accident and at a cost of $ 57 million , making it the most complex and costly accident investigation in Canadian history
