On the topic of public-private partnerships, in the context of the Canada Infrastructure Bank, these are certainly not mutually exclusive. One is a mechanism for designing, building, operating, maintaining, and financing, so they're not necessarily mutually exclusive. The Canada Infrastructure Bank could use public-private partnerships for investment purposes.
In the context of public-private partnerships overall, in the global experience as well as the Canadian, the jury is still out on whether or not the net benefit is there. It seems to suggest that ultimately there's a trade-off between a higher financing cost under public-private partnerships, but also a greater likelihood of having projects delivered on time and on budget. It's sort of a trade-off in terms of what the net benefit is there. If being on time and on budget is a key priority, P3s are seen as a very effective vehicle for doing that, but ultimately that comes at a higher financing cost.
