This is an interesting motion. It needs weight attached to it, of course, and it needs to be put into context.
The tar sands are a huge industry that is getting larger, and certainly the tar sands require other streams of Canadian production to make them work. We've heard that over and over again.
Essentially, sustainability is not linked solely to the site or to the product that's coming from the ground there. It's linked to a number of other things that would suggest pace and would suggest process. Ultimately, the judgment of some of these things will be based on...the sustainability will be linked to the pace of development and the processes used. That's a very complex look that you have to take at this.
I think it's correct, but to design a sustainability model for the tar sands, even within these three categories, is going to be a big job. There's no doubt about it. I think it's correct to go this way, but the resources of this committee in coming to those kinds of points are going to be a challenge.
