It's already been mentioned. The issue is transaction costs related to these projects. They're very complex contracts. You're right, we call them partnerships, but they're in fact legal agreements. There's a critical size needed to make these projects viable so that the transaction costs don't overtake the value-for-money proposition. Generally, we're looking at projects north of $50 million. I would argue that, first of all, if you look at these 180 projects, the majority have been built over the last five years, as Mark has indicated. Second, I would say that the majority of them are north of $100 million. Most small municipal projects are not good candidates, and there are a lot of complex renovation projects that are not good candidates.
As Mark said, P3 is not a panacea for all project delivery. As was the case in the U.K., it probably covers only 10% or 11% of the total capital projects inventory. It's just one arrow in the quiver, and when properly applied, it produces strong value for taxpayers.
