Nice idea in theory, lukecanada, but now let's look at reality. There is a worldwide oil glut and some economists now believe, due to the falling prices of solar and wind (and falling battery prices), that oil glut will continue for the foreseeable future. Saudi Arabia knows this and has decided to keep the price of their oil as cheap as possible to that they can make as much money as they can before their oil becomes a stranded assett. In such a situation, Alberta's bitumen will never be able to compete due to the relatively high price of production and refining. The Trans Mountain pipeline will become a white elephant. The smartest thing - both from an economic and ecological perspective - would be to never build it.
