I will give you a concrete example. In February 2017, we published our final report on the accident in Gladwick, Ontario. An issue of rail break came up. The train was travelling at a speed that was lower than the speed limit prescribed by the rules. The train was carrying crude oil.
After the accident, we recommended to Transport Canada to carry out a study taking into account all the factors that may lead to derailment, including the train's speed, length and contents—for instance, mixed goods or crude oil. We recommended that Transport Canada review all factors contributing to derailment, that it take measures to mitigate those risks and that it change the rules accordingly.
