Steve might want to come in on this later.
I would just note, although it's not specific to your question, that on Line 5, this isn't about increasing; it's about maintaining. We are also quite concerned—which is part of our advocacy with influence-makers and officials in the United States—about the implication of transporting that quantity of resources via other means, such as rail or truck, and the obvious risks involved there.
In terms of an integrated North American or bilateral energy market, it's exactly the point you're getting to in terms of the importance of ensuring that Canadian companies are taking advantage of both the front end and the back end. We talked about hydroelectricity, but there are renewables as well. Canadian companies have a lot to offer the United States in terms of their desire to develop this market. We see tremendous potential for Canadians in doing so. At the same time, with a more significant, more secure and climate-friendly energy supply down the road, this will also improve the attractiveness of investment in Canada and continue to build our ties outside of North America.
Steve, did you want to come in?
