There are two questions there.
First of all, going back to the question of enforcement, if you were to tell me that Transport Canada or the Canadian government is considering totally discarding enforcement, my comment would be that it's a very bold measure. I'm not sure I would agree with that. If you're telling me that Transport Canada is considering somehow changing or adopting its enforcement policies to reflect a more contemporary approach to enforcement underlying SMS, that's a completely different matter. They are not the same, as I'm sure you realize.
Secondly, you might have a million inspectors and be absolutely ineffective, and you might have 100 inspectors and be absolutely effective. So I couldn't comment on numbers. To me, the safety performance of the system should be the parameter, not the number of people manning the system.
