I can give you a practical example.
One of the things we do is investigate glider accidents. In Quebec, glider accidents are actually.... They do what's called a power pilot scholarship. They make contracts with civilian power companies that teach the kids how to actually fly, so when an accident of that nature happens, we have a vested interest in finding out a lot about it, whereas for the Transportation Safety Board, it's not a very high-profile investigation for them to dedicate resources to.
Sometimes they have been contacted. We've told them that we're going to do an investigation, and they say they're not interested. This would sort of demand that they show up. It would really impose on them a need to investigate something that we were investigating. In reverse, it has never happened. We have never not gone to an investigation they've asked us to go to, but certainly, although they've always been notified when we're doing an investigation that would have a Transportation Safety Board connotation, occasionally the Transportation Safety Board says that it's beyond their mandate, or that they're not going to send any investigator for that.
