The Globe and Mail reports in its Wednesday edition that Prime Minister Justin Trudeau might have taken a moment to thank U.S. President Barack Obama for the thoughtful housewarming gift -- his rejection of the Keystone XL pipeline. The Globe's Jeffrey Jones writes the President's move gives Mr. Trudeau's fledgling government the ideal setting to craft a sorely needed new policy for energy exports between the two countries. TransCanada may be able to rekindle Keystone XL, but Canada should move on. First, the government should be quick and clear about its intentions for the Northern Gateway pipeline. The project won conditional National Energy Board approval in 2013, but now, the Trudeau government looks intent on rendering Enbridge's efforts moot by banning oil tanker traffic on the Northern B.C. coast. It looks like a back-door way of killing the project, but that is unclear. Whatever moves the Liberals make on Northern Gateway, they should make them without dithering and deal with the fallout fairly. The collapse in oil prices means the urgency of adding massive new export capacity quickly has eased. That gives the government some time to put in place a sensible new system, but not forever.
