Follow the money. Who is the biggest beneficiary of this decision? The Americans get to keep the steady supply of cheap Canadian oil to keep their refineries running so they can sell the products back to us. It would be interesting to see where the bulk of the funding came from to pay for the extensive lobby against this pipeline.  Of course the Canadian government provided the final straw with the environmental baggage recently added on.

This is the biggest loss to the future of the Canadian economy in a generation. There is no other potential project that could have provided such a huge positive benefit for jobs and export income. People better start worrying about Canada's  ability to afford the standard of living we have enjoyed so far.
