The Transportation Safety Board, TSB, an independent agency which operates under its own act of Parliament and reports to Parliament through the President of the Privy Council, is conducting an investigation of the circumstances of the accident. The TSB will issue a public report once its investigation is completed. Any recommendations made by the TSB will be acted upon by Transport Canada should any factors be identified which could lead to further derailments and subsequent leakage of tank cars carrying toxic substances.
In the interim, Transport Canada's transport of dangerous goods directorate is reviewing the design standards of the particular tank cars involved in the derailment to assess the possibility of enhancing their safety performance.
