I think at the heart of it is a large infrastructure deficit in Canada. That's prompting a really serious look at how to address that issue, and again we're in a time of fiscal challenge, so that requires a really good look at possible approaches. Which are the most innovative ones? That's prompted a lot more interest in the case of P3s.
As I mentioned earlier, I think you're seeing this growth in the market reflected in provinces that haven't historically been active in this space—Saskatchewan is a case in point—and a growing interest on the part of municipalities that are looking at this approach.
