Canada is a price-taker. As I've tried to say, these major refining centres tend to be the price-setting marketplaces. So other markets besides them take their prices from these major refining centres for both crude oil and crude oil end products. That's the first point.
Are speculators having an impact? They may very well be having an impact. Are they doing it legally? I think time will tell. I think the U.S. is actively trying to find a bogeyman. Will they find one? My sense is no, but they may. I mean, I was surprised by Vitol's position in the NYMEX, but I don't think that is conclusive about anything.
Again, I'll try to make this point: these are separate markets; nobody is controlling the physical market. Crude is bought and sold via hundreds of thousands of transactions a day, and nobody has enough storage to be able to control it to really move the market. So somebody may be playing with the futures market, which may be having some impact on the physical market, but I don't think it's appreciable.
