The pump prices are not uniform in terms of the market. You can drive around Ottawa and find all kinds of different prices. So I have trouble understanding the question.
If you're talking about the rack prices, I think most of the companies follow a very similar methodology. They look at what has happened to the wholesale prices, at least in eastern Canada and in New York. What's my supply demand? If everything is normal, then I'll follow the normal market. I've seen cases where one company happens to be in distress and they move their rack prices higher again to push demand away. As Tony said, supply flows to a higher price and demand flows to the lowest price. That's how the markets balance themselves.
