To those commenters who believe that this is simply all about three Green party candidates who won in the recent BC election ...

Ms. Notley's observations re "Canada's interests" were superficial and entirely self-serving. She clearly does not grasp that this is an INTERNATIONAL dilemma, not just a BC one, or even just a Canadian one. 

Mr. Trudeau wants the pipeline built because the government of China has dictated ... yes DICTATED ... to all of us Canadians that a pipeline to tidewater in exchange for a climate-change plan is non-negotiable; see here: 

"Michael Den Tandt: Trudeau’s China strategy fails unless he gets a pipeline built"

Yet dilbit (NOT presently carried through the present TM pipeline) sinks in ocean water. Kinder Morgan, an American corporation, reaps the financial benefits of TM, the Chinese economy gets ALL the oil products, and we Canadians (and the planet as a whole) get nothing of any true long-term significance except potentially massive ecological damage.
