Again, Rick White may want to comment on it, but in answer to that, I would say that by and large we're very pleased with the regulatory process that applies in Canada. It's science-based, it's reliable, and it's timely. I think there will always be people who would like to see a more timely process in some cases, but by and large, it's a system that can be relied on. It's highly competent and science-based, and we have very strong regulatory processes in Canada.
The one departure from that, which we've been referring to in this committee meeting--and you've heard this from us before--is the whole area of low-level presence. It's not so much a review of the overall kind of complicated process, but more an issue of keeping up with the changing landscape around the world and some challenges that are coming up in terms of regulatory compliance for systems based on zero tolerance. But it's not suggesting an entire review of our regulatory process.
