Yes, I've watched "Over a Barrel". It doesn't directly affect northern communities, except for the notion of Army Corps of Engineers changing the direction of waterflow for the rivers naturally flowing north.
The Trans-Mountain pipleline purchased from Texas-based oil company Kinder Morgan by the Liberal government for $4.5B, was a waste of taxpayer money IMO. Besides the environmental impact, current oil glut and price of crude dropping, together with opposition from several First Nations whose land it crosses, it makes little sense other than the pain of Alberta surviving without the oil patch.

The Keystone Pipeline is a little closer, but it still takes roughly 14 hours by winter road from here to North Dakota. I noticed it's up and running again after another major oil spill
Canada currently sends approx 550,000 barrels of oil per day to the US via the existing Keystone Pipeline.
Obama blocked permits for the Keystone XL pipleline to expand. Upon election, Trump issued an executive order for construction to begin, but the Supreme Court upheld opposition by environmental groups, requiring that new oil and gas pipelines must have permits and follow a strict regulation process in order to build across bodies of water.

Those who think that water is not important should consider this:
1 gallon of oil contaminates 250,000 gallons of water... that is what I call filth!
