Lone Pine Resources Inc., which is incorporated in Delaware but headquartered in Calgary, has filed notice that it intends to sue under provisions of the North American Free Trade Agreement.

Lone Pine says the Quebec government's move to cancel a natural gas exploration permit for deposits beneath the St. Lawrence River last year was "arbitrary, capricious and illegal."

Details of the claim for arbitration are contained in a notice filed Nov. 8 on the website of the Department of Foreign Affairs and International Trade.

Lone Pine cites Article 1117 under NAFTA in making its claim for the loss of a "valuable right … without due process, without compensation and with no cognizable public purpose."

Lone Pine says the suit has been filed against Ottawa because it is responsible for acts by provinces both under NAFTA and international law.

Firm spent millions on permits

Quebec passed the moratorium in order to study the controversial process in which fluid under high pressure is pumped underground to release petroleum from rock formations.

Environmentalists contend fracking risks contaminating ground water, while the industry says it can be done safely.

Lone Pine said that between 2006 and 2011 it had spent millions of dollars as well as time and resources to obtain the Quebec permits.

"Suddenly, and without and prior consultation or notice, the Government of Quebec introduced Bill 18 . . . to suspend all exploration for oil and gas in the province (except for the purposes of scientific studies onshore.)

Lone Pine said all attempts to discuss the matter with the province were "repeatedly rebuffed" and that it had been told the move was "a political decision and that nothing could be done to prevent it from being passed."

"It is Lone Pine's hope that this dispute can resolved amicably through consultation and negotiation," the company said in its notice. "However, is such consultation and negotiation is unsuccessful, Lone Pine will pursue arbitration" under NAFTA.
