I appreciate that. Obviously you learn lessons from tragic incidents like the one at Lac-Mégantic as you move along. The Transportation Safety Board has been instrumental in ensuring that as they progress through their investigation, they're providing us with feedback. One such piece of feedback was regarding the content of the cars in Lac-Mégantic. Indeed, as a result, we issued the directive I pointed out at the beginning of my speech, to ensure that any crude oil being transported be properly tested to ensure that it's rated at the right flammable stage and to make sure that whatever data sheets are being carried with the train or are available for the train match up with the actual contents. That's their directive now for the companies doing business in Canada as well.
Finally, in the case of this incident in Lac-Mégantic, a number of things were reported by the Transportation Safety Board, which we have been made aware of: it was a single-operator train; the cabin wasn't locked; and the train was left unattended. Those are the things on which we did emergency directives. There were further directives to the companies to make these regulations and orders permanent.
Those are the things we learn and we take into account as we move along, and we ensure that whatever we learn from the incident we implement and will continue to do so as the Transportation Safety Board continues to discuss its findings with us and with the Canadian public.
