Canadian pipeline operator TC Energy is looking to recover more than US$15 billion in damages from the US government over the cancellation of the Keystone XL pipeline project, with reports indicating that the Alberta provincial government also will be joining the fight.

Earlier this month, TC Energy filed a Notice of Intent to initiate a legacy North American Free Trade Agreement (NAFTA) claim under the US-Mexico-Canada Agreement to recover the economic damages suffered because of the US government’s revocation of the Keystone XL Project’s Presidential Permit issued by former president Donald Trump.
