That's not what P3s deliver. P3s in Canada are on budget. They're on the balance sheet; they're not a way around it. If you're doing P3s because you're trying to do off-balance-sheet financing, you're doing P3s for the wrong reason.
Why P3s? P3s grew out of an analysis of the problems of traditional procurement. There were three or four main problems that people identified in the way things were procured, and they tried to find solutions for them.
What were those problems? One problem was that the government would pay for something and then it wouldn't get what it wanted. Then the money is already paid, and governments are terrible at getting their money back. If you don't pay until they deliver, then you know that the risk is theirs. Also in that world where, if you have to build a major piece of infrastructure and you have to go to the capital markets and borrow $500 million, let's say, from investors to execute the project, and those investors are only going to get paid back if they're successful in delivering the project, the oversight that comes from those types of creditors is a discipline on the project that is incredible. Private capital brings discipline.
