Without question, it's an important issue.
Within the course of the past year we've had a very unusual situation in Canada. We had global oil prices go up, and normally that would be net positive for the Canadian economy. There's adjustment, but the flow-through effects, including through government, mean that higher energy prices globally are normally net positive for the Canadian economy. But in that specific situation with higher Brent prices, you had a big discount, so you had this revenue loss in western Canada, and because Brent is more relevant for the pricing of gas in eastern Canada, and central Canada to some extent, you had the loss in terms of disposable income, because higher gas prices outweighed what normally would have been a benefit on the revenue side. Fortunately, since then, the differential has narrowed somewhat, as you know, in recent weeks, but as I said earlier—and we put the data in there just to make this point—it's very volatile. It's a very volatile price because of these infrastructure difficulties you highlighted.
There is no question that there is a wide range of energy infrastructure projects—and obviously we don't favour specific projects or companies—that can benefit Canadian producers and Canadians as a whole, that can reduce at a minimum some of these differentials between high global prices of crude and lower prices received by Canadian producers so you can get gas prices down in eastern Canada, and that can provide an ability to supply reliable energy to the United States. I think one of the things—and we've made this point, but we should make it again—is that there has been an energy revolution in the U.S., and that's positive for the U.S. economy, but the prospect of energy security in the United States is still not within sight. There is North American energy security. In order to have North American energy security over time, there will need to be additional infrastructure investment, which will benefit both economies, but very importantly the Canadian economy as a whole.
