I think one inquiry—and it's a part of what you're looking at here—that would be very useful is an inquiry into why we're not seeing more investment in the supply of refined petroleum products in Canada, and perhaps in North America. Part of the problem in the North American market is that demand is high and there are lots of uncertainties around supply, particularly during hurricane season in the United States. The fact that we have not seen investment in modern manufacturing and petroleum refining facilities is I think one of the major reasons we're seeing some of these spikes in prices.
That would be a very useful inquiry, I think, because it would raise a number of issues not only about that industry but about the state of investment in manufacturing and processing in general.
