2. The canadians can build their own export facilities in Canada entirely bypassing the US. The canadians already take your position as a betrayal of our shared economic arrangement. The deal was that we'd provide certain assets to them and in return we got first bid on resources. You've made liars of us and the canadians are not happy about it.
Previously, then-Representative Markey challenged TransCanada on this question at a hearing of the House Energy and Commerce Committee on December 2, 2011. There he asked Alexander Pourbaix, TransCanada's President of Energy and Oil Pipelines, whether he would commit to including a requirement in TransCanada's long-term contracts with Gulf Coast refineries, as a condition of shipping, that all refined fuels produced from oil transported through the Keystone XL pipeline be sold in the United States. In response, Mr. Pourbaix stated "no, I can't do that."
Go ahead, build your own export facilities and ship the stuff to China.
I'd much rather Canada not externalize the environmental cost of that infrastructure onto the USA.
