Briefly, on the question of clean technologies, and again it's something we should probably spend a bit of time on--we didn't particularly touch on it, but clearly it's something that all of our industries are involved in. My industry actually made some proposals before the finance committee a couple of weeks ago, with some ideas for the way we can introduce cleaner and more efficient technologies into the energy delivery system in Canada's cities and towns. There are lots of things we can do there. In some places we need a bit of help from provincial and federal governments. There are other areas where our companies are simply investing in that because it is the future.
I don't want to belabour it, but I just want to come back to the speculation point, because it's important in terms of the way these things work. There's a fairly straightforward trade-off; my colleagues alluded to it. If you lock in, you lock in. You could lock in high when a market may be going down, and you'll pay for it. One of the reasons, as I said, customer intervenors in our regulatory processes actually don't want us, the gas delivery industry, to contract long is that they're not sure we're going to do it the way they would like it to be done. They actually prefer to follow the market and manage their own market risk. That may be the right way to do it. I think, as they say, there are some arguments for long-term contracts to underpin investments, but there is a pretty straightforward trade-off there.
