Let me just make a couple of observations in response to your question. The first is just to clarify the proposal that we've made. On the scientific research and experimental development program, it is to broaden the eligibility. So we're not asking for the introduction of a new program; it's simply to broaden the scope of expenditures on technological innovation that would be eligible for that program. And some, and I think in fairness a large part, of those expenditures would be directed to environmental issues. So it is a way to stimulate an incremental investment. It is not the introduction of a new program.
With respect to oil sands, let me just make a couple of observations. I would first say that oil sands is a key part of the Canadian economy. It does create a significant value across the country. It creates significant employment across the country, and we think that tax measures that can help to stimulate investment in oil sands would be a positive measure. I would also say, on environmental performance, the industry clearly understands that it needs to improve its environmental performance, and in no way in our representations to the committee do we suggest that is not the case. We're simply saying that there is an opportunity for the government, through tax measures, to encourage incremental investment in technology, which we think is a key lever for environmental performance, for cost reduction and improving recovery. So environmental performance is absolutely a key part of what underpins our proposal.
