  • the risk of implementing single-person train operations
  • the risk of not systematically testing petroleum crude oil
  • the risk of not planning and analyzing routes on which dangerous goods are carried
  • the risk of not having emergency response assistance plans in place
  • the risk of Transport Canada not ensuring that safety management systems work effectively”
