I have one quick question, and then I'll turn it over to Ms. Block.
From my perspective with the oil industry, my guess is that in the short term what they'll try to do is develop a refinery, whether it's in Prince Rupert or in Kitimat, and use the rail lines there and refine it down to varieties of gasoline, diesel, etc. Obviously, those are allowed to be shipped across. Do you feel that there's a potential for huge increases in tanker traffic of those products? Is that something that you're looking at enforcing down the road, to take those off if the volumes become too high? Could you let us know what you might do in the future?
