Yes, and let me be clear that our suggestion here on performance-based versus prescriptive regulation is not to be interpreted in a negative way towards Transport Canada. Transport Canada is very familiar with the concepts and the differences between the two of them. We have a very professional and productive relationship there. They understand these issues. I think they're very supportive of these issues in a lot of ways. There's a lot of dialogue going on there.
In our view, to really reap the benefits of the technology that can be available, we need to get over the old prescriptive way and start to embrace, perhaps, a little more the performance-based approach. But people are coming around to that. There's no question about it.
