Ms. Nash, thank you for the question.
Yes, there's no question that there's a significant degree of volatility in gas prices. I think everyone would agree that this can be very distressing for consumers.
I would just reiterate that ultimately the price paid at the pump is a function of three markets. One is that there are, yes, global implications in terms of setting the price of crude, which is the most significant component of the price of gasoline at the pump. There are North American markets, and we've had a significant discussion already this morning around the North American wholesale market for fuels. Then ultimately there's the retail market; that is, across Canada, thousands of individual decisions by retailers, who set the price at the pumps based on local market conditions and the assumptions they make and the information they have with respect ultimately to supply and demand conditions within their local market.
As they respond to that level of information and the information that's relevant to their market, they're going to adjust prices as they see fit to meet their business objectives, recognizing that this is an industry—the only one, to my knowledge—that posts prices at the street level on signs as large as you and I are. Consumers in Canada and around most parts of the world are very sensitive to those price differences. A tenth or two-tenths of a cent per litre difference will cause a consumer to change behaviour and choice of service station. As various retailers look at that and decide they're not going to lose market share to a competitor and can see that price change across the street, they're going to respond as they see fit, based on their business model.
