If I might be allowed just to address the question that was asked by my honourable colleague across, bitumen is an upgraded product. It is already upgraded at the source in what some people call a refinery and others call an upgrader. But that is essentially what you have. They have refineries that are already there ready to go. It's not economical to build new ones. It is economical to add on to existing ones. My understanding is, as well, that there's a very large area of land that's available already for expansion.
Maybe you could just talk to that briefly, Mr. Norton.
