An investigation is under way, both from our current terms in a regulatory sense and from the Transportation Safety Board's review. The degree to which I'd be able to comment on that is fairly limited.
A system is in place for all changes with regard to single person train operation or other major changes in operation, and the company is required to do risk assessments before any major change. They are required to look at the mitigation methods and then they are required, in this case and in other cases, to consult with affected municipalities, etc., in some cases with labour and then the information is provided to Transport Canada.
If we have a concern about what the process proposal is, what the mitigations are, we have various tools to deal with those. That's the general process.
