Transport Canada's role, in this particular case, is to conduct an occupational health and safety evaluation. The big evaluation is being done by the Transportation Safety Board. This is the body—and as you know, it is independent from Transport Canada—that is called in to investigate whenever a transportation accident or incident occurs, and it is busy doing that.
I can assure you that TSB is a very professional organization. At the end of this, based on the gathering of all the necessary information and speaking to all the required people, it will conclude what the cause was and will follow that with recommendations. Those recommendations could come to Transport Canada, to CP or to a number of other organizations.
