Mr. Chair, if I may, I'll speak directly to the SMS—safety management system—regulations. Those regulations were promulgated. They came into force on April 1, and the companies are now in the process of converting their systems and establishing some of those new elements that I touched on in my introductory comments.
Our staff will be going out over the next few months, initially making sure that the railways understand how to incorporate these many changes and these many additional requirements, one of which is the process you've just touched on. We will get more information as to how they are approaching that. But the onus is on the railway company to develop a policy and a system to accomplish those objectives in terms of the first issue.
In terms of fatigue science, there's a very extensive section of the regulation that outlines what factors railway companies need to take into account in scheduling work. That is where the fatigue science principles and a broader set of additional parameters have been added to the regulations and are in place now, and they are responding to those now.
