I can elaborate, but I think that you will also hear from Transport Canada representatives later, and they will probably be in a better position to give you the details you want.
However, I can tell you that a change was made to the Railway Safety Management System Regulations, 2015. Operating certificates for railway companies were introduced, and the number and extent of checks or inspections of railway companies carried out by Transport Canada was increased. Fines have also been introduced for companies that don't comply with the railway safety act or regulations. Furthermore, the removal of the least crash-resistant cars was ordered, as was the implementation of emergency response plans in case of derailment.
All those measures have reduced the risk, but they have not completely eliminated it. Action is yet to be taken in response to three of the five recommendations we issued in the aftermath of the Lac-Mégantic tragedy, and two other recommendations we issued after the derailments in northern Ontario in 2015. We will continue to monitor this file until all our recommendations have been implemented in a fully satisfactory manner.
