With regard to the $20 difference between the Canadian price and the international price, not all of it can really be reduced by having the pipeline. Historically, there's something like a $10 or $12 difference between those two, so the additional amount, maybe the $8 to $10, is due to the problem with the pipeline and the lack of capacity to get that oil to the market.
