To respond to your first comment, you're quite right, there's been no new greenfield refinery investment in Canada for some time. In fact, over the last 15 or 20 years, we've seen a significant consolidation in the number of refineries in Canada.
You're no doubt aware that there have been a number of proposals on the table over the last couple of years for potential new refineries. Unfortunately, the current economy, as one major factor, has caused some reconsideration of that, and those investment decisions have either been made not to invest or at least to defer any decision on that kind of investment.
That's not to say that refiners have not been making investments in increasing capacity and addressing in particular environmental issues. In fact, the investment over the past 10 years by refineries has been in excess of $10 billion.
Yes, there have been some short-term local situations with respect to unforecast outages at refiners, but I can tell you that refiners don't like that any more than customers do, so they're continuing to work at continuing to strengthen refinery reliability.
That said, if you look on a North American basis--and this is a North American market for refined petroleum products--the investment climate for expansion is not particularly pleasant. Demand is certainly well down from its peak in 2008, more so in the U.S. than in Canada, but still it is a North American market, and there's a lot of talk now about, on a North American basis, the significant overcapacity on a long-term basis, not on a short-term basis, and the need for further consolidation on a North American basis.
The investment environment clearly will determine where investments will be made and what investments will be made, but certainly refineries have been doing that.
