I've recently undertaken a study of the four Atlantic provinces that have regulated, and every province, including Quebec, has a different form of regulation with different purposes. From my research, I would say that none of the provinces undertook regulation with the intent of lowering gas prices. The intent, by and large, generally was to enhance competition in the retail markets by ensuring a certain margin at the retail level. Quebec would be an example of that. It would be to stabilize prices to a certain level, rather than, for example, Toronto six months ago having 12 price changes a day. So stabilization was an objective in the five provinces that have regulated.
Also, there's transparency, so that when consumers fill up their gas tanks--for some people anyway--there's more comfort that the price was set by a transparent mechanism as opposed to refiners or oil companies. In some provinces, the benefit is, again, transparency for regions. We sometimes see extreme differences in prices between regions. Let's say in an urban market, prices might be much lower than in a rural market, or a far-away market. Those constituents who are in distant markets find it galling that there is such a price difference.
Those are the things that regulation tends to address.
