The Transportation Safety Board of Canada (TSB) is an independent agency created in 1990 by an Act of Parliament (Canadian Transportation Accident Investigation and Safety Board Act). It operates at arm's length from other government departments and agencies such as Transport Canada, the Department of Fisheries and Oceans, and the National Energy Board to ensure that there are no real or perceived conflicts of interest. Under the legislation, the TSB's only object is the advancement of transportation safety in the federally regulated elements of the marine, pipeline, rail and air transportation systems.
