Not to disagree with your post, but Energy East won't help with any of that list except accessing new markets.

We produce 4 m bbl/day, but we only use about 2 m bbl/day, which is what we refine.  Energy security is not a problem -- really only BC needs another refinery for their domestic market.

We import mostly light oil to the refineries in Quebec and NB that can't refine heavy oil from western Canada.  Energy East isn't going to change the need for imports of light oil.

Most of the oil we import is from the US.  I don't have a problem buying several hundred thousand bbl/day of light oil from them when they're buying a couple million bbl/day of heavy oil from us.  We're the net winners here.

And by the way, as for value added, eastern refineries aren't just buying light oil from the Americans, they're also selling a couple or three hundred thousand bbl/day back to the northeastern US as refined products.
