I'll talk about the consequences of not building the Keystone XL pipeline or the Northern Gateway pipeline.
That would really close in production of Canada's oil sands to a significant degree. The line 9 reversal would by no means be sufficient to continue the progression of Canada's oil sands production. That's the first fundamental concern, if you will, or consequence of not proceeding with those first two pipelines.
Vis-à-vis energy security, I don't think there's as much of a concern there from a Canadian perspective as some might imagine. There certainly are a lot of safeguards already in place in a North American context. Should a worst-case scenario occur, the United States, for example, has a huge strategic reserve of crude oil that would keep that country going for quite some time—not weeks but months. Again, in a North American context and given the NAFTA provisions, we have a degree of security by that means alone.
I simply cannot imagine a scenario where the east coast could not receive supplies of crude oil from some source, given their proliferation of upstream capacity in non-OPEC countries, for example, non-Mideastern countries, right around the globe.
