Maybe I can start and Greg can certainly add any details.
I think the main reason the model was chosen—and by the model, I'm referring to the fact that PPP Canada is a non-agent crown corporation—is that PPP Canada is undertaking infrastructure projects with other partners. It does so though contributions, and the projects are of long-term duration. In this case, because they are private sector managed, the view was that it was appropriate that PPP Canada be a non-agent of the crown. I think the main advantage of doing that is that these projects are undertaken without the crown being bound to any future liabilities that might be created as a result of the projects. It holds the crown harmless.
