Madam Chair, I'm not sure how far I can speculate on those kinds of broad questions. I can tell the committee the process of engaging Canadian government agencies, including Transport Canada, on the regulatory side in various initiatives—where we look at reducing red tape and regulatory coordination, and co-operation with the United States for example—is a process that bring us closely into the discussion of safety priorities, and what are the safety priorities. In all cases the safety priorities are our primary consideration. When you look at the mechanism of how things can be done, and when you look with a fresh eye, you do find areas where things can be streamlined or modified. Whether something in a regulation is a core element that speaks to safety, or it's an administrative process that may or may not be burdensome, those are analyses that are useful to do. We take part in that work on a regular basis.
In terms of where any kind of a regulatory safety issue is raised, or an issue that may be best dealt with by a regulation, it may come up through a variety of areas of findings, such as Transportation Safety Board reports, our own analysis, international incidents, work with the U.S., and others.
When such things happen, we look at the safety implications and look at what new regulations should come forward. I would refer to the point that I made a couple of times in my opening comments. These regimes need to be continuously improved, to be continuously monitored for their effectiveness, and to be updated as required.
