Enviro is right and I will say for the third of fourth time.  Oil is going to hit the low 40s or high 30s and the likes of Meg Energy, Baytex and even the not so long ago mighty Cenovus going tits up due to their indebtness.  I remember a commenter here saying that Cenovus  bought deal through the banks could not go any lower, and that they stole it from Conoco Phillips......well buddy  look at the chart as Cenovus appears to be heading towards ZERO.  Remember an oil company called Oilexco....the darling of the market back in the 08 to 09 period....its been dust now for close to a decade and for everyones info, long before the US became a world power in energy.
To add to my comments on the above.....Keystone will never be built unless its for transporing humans in some new form of fast transport. We may be importing oil from the US due to their efficiencies compared to the oil sands.
Alta go back to tourism and ag.....tarsands are pretty well finished.  
Sorry to tell the truth.
