I'll give you the general review, and I'll turn to Laureen or Luc to supplement because they're really the experts.
The fundamental concept of inspections are typically inspections of either tracks or specific operational procedures. They're inspections of activities or assets to note whether they're compliant with regulatory requirements, and in the rail case, regulatory requirements take the form of either regulations we impose or rules that the companies develop themselves and that have the same statutory status in terms of regulation.
This is a traditional method of surveillance of safety. SMS is about saying it's not good enough to just look at the activities and the assets, because we will never have enough people to look everywhere all the time. We need to ensure the operators take charge of security. It's not about removing the regulatory scheme and inspection, in addition to that; it's about building a new system of safety management systems, putting the responsibility on the operators, and then it becomes the role of the department to audit those systems to see whether the systems have been established as adequate and whether they're implemented adequately by the operators.
In the process of gathering data that's also helpful in directing the inspection program to areas of highest risk. We take in stride the basic message, not being fast enough in fully implementing this additional element of safety in our surveillance regime. We're obviously very committed to the timelines we've described, putting in place the framework that will ensure, or give us a level of quality assurance, that we are putting that in place on a systematic basis. The report notes a significant progress, a number of steps have been taken. You cannot say that you have on a nationally consistent basis, on a systematic basis, all the data and evidence that shows you have fully implemented that. That's what this action plan is about.
