As part of its mandate, the TSB makes recommendations to eliminate or reduce safety deficiencies that pose significant risks to the transportation system and warrant the attention of regulators and industry.
Under the Canadian Transportation Accident Investigation and Safety Board Act, federal ministers must formally respond to TSB recommendations within 90 days and explain how they have addressed or will address the safety deficiencies. The Act does not require other stakeholders to respond to the TSB's recommendations, but they usually do.
Using the Assessment rating guide, the Board assesses responses to recommendations according to the extent to which the safety deficiency has been or is being addressed. Once the responses have been assessed as Fully Satisfactory, the recommendations are closed. The TSB continually monitors the progress being made on its recommendations.
