As a result of NAFTA, North America is already a well-integrated energy market with Canada and Mexico among the U.S.’s top energy trading partners.  Through the Security and Prosperity Partnership (SPP), the North American Energy Working Group has further integrated a continental energy strategy.  Other initiatives are also pushing towards a single North American energy policy.

The Western Governors’ Association annual conference was held in Park City, Utah on June 14-16, 2009. The meetings were attended by three Canadian western premiers.  Montana Governor Brian Schweitzer and Saskatchewan Premier Brad Wall spearheaded plans to develop a cross-border Western Energy Corridor.  Both have announced that they intend to establish a Western Energy Corridor Coalition to further promote the initiative.  The proposed energy corridor would be the largest of its kind in the world.
