I can't talk to all of the necessary details, not being a pipeline expert, but first I would clarify that we do have two kinds of pipelines in Canada. The pipelines that ship crude are distinct from the pipelines that ship finished products. We do not mix crude and finished products in the same pipelines.
We have a number of pipelines, particularly in eastern Canada, that ship finished product from refineries to major market centres. The products that go through those pipelines are different on a day-to-day basis, depending on the demand and how the pipeline schedule works. You cannot ship gasoline and diesel at the same time. You ship gasoline, and then you need to ship a load of diesel after that.
Certainly the longer distances you try to do that, the costs do increase. I think that comes back to the principal discussion we had earlier this morning, that because of the costs and the inefficiencies involved in shipping finished product over long distances, generally the refineries have been located closer to market.
As for the costs, I don't know what would be the specific incremental costs.
