Let me start with the question about the $40-a-barrel oil.
I think we all realize that predicting where oil prices are going to be next month, let alone five or ten years from now, is a pretty difficult challenge. The oil companies, not just in Canada but internationally, have been pretty conservative in the kinds of price assumptions they've made in deciding to go ahead with investment decisions. Of course, on any particular project that would be proprietary information.
I think you'd find that most oil companies in Canada and abroad assume that the price is going to be $30 or $35 a barrel, so my guess would be that if in fact prices fall to $40 a barrel, it's unlikely to have a major impact on the expansion of conventional Canadian supply in western Canada.
It's in the nature of markets to overshoot on both the upside and the downside. You can even have prices going below that for a period of time, without significantly affecting investment. Where I think you'd have a problem is if prices fell well below the levels that companies are assuming and they start having cashflow impacts. But I think we're a long way from that situation.
I'm not entirely sure that I followed the question about gas and oil prices.
