I think it's important to put the $5.5 billion into context and to consider the scale. I don't want to focus on Gateway, because the same could be said of expansions on the Kinder Morgan line. Either way, infrastructure investment to provide the choice of exports does not take away from the economic options of you might choose with respect to bitumen in Canada, just like building a new highway doesn't predetermine whether you're going to have shipments of oranges or shipments of orange juice.
It is about having appropriate infrastructure to create options in terms of trade. I'm not an expert in terms of netbacks, but I would also say that directionally there is a significant discount on Canadian crude right now because of having only one market. Just the differential, and the government revenues related to that, if you had multiple markets, can in itself create a huge economic opportunity to reinvest as you see fit as government.
