Thank you for the question. There are a lot of questions there.
I'll do two really quickly, and then I'll turn the third one over to my colleague Mr. DeJong.
On the first one, Transport Canada took significant action on all of the recommendations in the 2013 report, and I am happy to elaborate later.
On the second one, the rail safety system is vastly improved today relative to what we had before the Lac-Mégantic tragedy, so the risk profile is completely different and much lower today.
On your third question, with respect to scenarios and response plans as they fit into SMS, I'm going to turn it over to Michael.
