In the normal course of our work it's not something we would track. We may do so from time to time, when we do get complaints about high prices, whether it's high wholesale prices or high retail prices. Or sometimes we get complaints of predatory pricing, where some players in the market may be pricing below a certain measure of cost for a certain period of time. We will look into those situations of what's going on with the wholesale price.
We look at the differential between city pairs, just like Natural Resources Canada does with Fuel Focus, when it tracks, for example, the wholesale price in Toronto and the wholesale price in Buffalo. What we usually see in comparing those two markets is that prices usually move in sync, in unison. You'll also find there's usually not very much gap between the prices.
I think, as we heard, it's market dynamics: if it's cheaper for a refinery or a marketer to buy gasoline in Buffalo, then he'll go to Buffalo to buy it, and if it's not, he'll buy it in Toronto.
But it's not something that we track as a matter of course.
