With respect to the question about water, I think there's no question but that the availability of water is potentially a constraint on oil sands development, because not only is oil sands production energy-intensive but it's also water-intensive.
You'd asked whether we were taking mitigating measures, whether we were monitoring, and so on. I'd observe that any oil sands project coming forward would be the subject of an environmental assessment, including scrutiny under both the Navigable Waters Protection Act and, importantly, the Fisheries Act. So my answer would be yes, on a project-by-project basis, that kind of scrutiny would be a matter of course.
I think your question, though, was a bit different. It was more about the long-term vision of the law as opposed to the kind of micro examination of it block by block. That is an important question, and one that I think the producers are very aware of. The figure that sticks in my mind--and Hassan, you may know this better than I do--is 90%. I believe 90% of the water used now in typical oil sands production is recycled.
