It's difficult to make forecasts into the long term. There's still lots of uncertainty. We've seen huge swings over the last three or four years in demand, prices, and cost, so it's very difficult. At least in my crystal ball, it's not all that clear in looking out in the future. We saw the price of crude in the summer of 2008, and then we saw the price of crude early in 2009; six months in advance of that, would either of those have been forecast? I doubt it. Certainly my forecasting ability is not that good.
If you look out a number of years, there's a lot of uncertainty about where demand is going to go. We're seeing increasing emphasis on alternative fuels and transportation, so there's a lot of uncertainty in the market. There's a keen interest within the industry to continue to be a viable and competitive part of Canada's economy, and they're going to take the steps to do that, but, as I've indicated in my remarks, there are some policy issues that will have some impact on whether the right investment climate exists for investing those billions of dollars when payback times are very long.
