Can someone please explain why this pipeline is not being run from Alberta to the Vancouver habour?  Most of the oil is tagged for sale to China.  The all-Canada route would end the fuss with the Americans as well as Trump's attempt to squeeze 25% royalties out of the project.  There's no guarantee Trump won't attempt to jack up those royalty rates once the pipeline were completed and oil running through it.  Why not a route to the Canadian west coast?
