Calgary-based TC Energy Corp announced this week that it is terminating the Keystone XL pipeline project. Gone is the promise of the daily export of 830,000 barrels of Canadian crude. Gone are the tens of thousands of direct and indirect jobs, the billions of dollars in taxes, and decades of prosperity for Albertan communities. After a 13 year odyssey of regulations and government doublespeak, the company is absorbing its loses, closing its doors, and walking away.
