The risk is not so much affordability, which of course I did mention before, but it can be an availability issue when we're talking about energy security.
Specifically, we have eight major suppliers to eastern Canada. The U.K. and Norway, as I mentioned earlier, both peaked; Saudi Arabia has effectively entered a plateau; Russia has peaked; Venezuela has peaked; and Nigeria is in a plateau. So with respect to production, some of our major suppliers are having difficulty maintaining supply.
The other side of the coin is what type of domestic and political security risk do they have? Although some of our major suppliers, like Angola and Saudi Arabia, haven't necessarily peaked, they are in regions of the world where they may be politically unstable, and of course it's the same thing with Iraq, which eastern Canada relies upon.
