Best practices in the leading jurisdictions, which I say have been the U.K., Australia, and continental Europe, seemed to coalesce around finding the appropriate role for private capital so that there is an appropriately structured transaction that gives a long-term predictable cash flow adjusted for risk, making sure that private capital doesn't just get a free ride but actually takes appropriate risk, and for the incremental cost of private capital ensuring that they bear risk so that the overall cost to the private sector of the net present value of the transaction is superior to government doing things alone.
It is making sure there is aware, interested, invested skin in the game. In terms of figuring out how that works, in Canada our transactions tend to be highly levered so they're minimal risk after the construction period, so 90% debt and 10% equity. In other jurisdictions we find private capital absorbing volume risk, on toll roads for example. That has not been a feature of the Canadian market.
