Personally, I wasn't all that bothered by the Energy East Pipeline as it would be just another pipeline among the thousands and thousands of km of pipelines that are already in the ground. And the vast majority of them just sit there and don't cause any problems. (And I'd be more worried about older pipelines rather than newer ones for obvious reasons)

But the price of oil seems to be hovering at $50 and it doesn't seem to be moving much above that. If TransCanada thought they were going to be making buckets  of money out of this, they probably would have gone through and jumped through the extra hoops. 

But I guess in Alberta it is just so much easier and comforting to "blame Ottawa" rather than admit that low oil prices mean some projects get cancelled.
