The Canadian Transportation Accident Investigation and Safety Board Act requires that federal Ministers provide formal responses to the TSB as to action taken or planned in response to our recommendations.

The Board also makes recommendations to other organizations and will assess all these responses and evaluate the degree to which they address the safety issues and deficiencies using an Assessment Rating Guide.

For recommendations and assessments made prior to January 1, 2005, please refer to our Annual Reports.
