Mr. Regan asked a similar question on the factors that influence cost, and ultimately profitability and viability of a refinery.
Certainly proximity and access to feedstock is one, but it's not the other. We talked a bit about it. It used to be that close to market was the most important part. It's one of those many factors, but the factors are complex. You run into issues like crude feedstock—the type, access to it, how close they are, the energy requirements, and the access to energy. We talked about the issue of natural gas in Atlantic Canada and the disadvantage, at least to one refinery, of no access to natural gas, which has an impact on their cost. Then you get into all the issues around plant complexity, plant efficiency, plant size, various logistics in transportation issues, and, of course, then there's the regulatory environment.
It's a complex set of variables. I wish it was that simple—
