Northern Gateway Pipeline: Something I Didn't Know

There is also an interesting wrinkle in the JRP’s [Joint Review Panel's] decision, specifically its inclusion of a “sunset clause.”

And that states “the certificate [to proceed] will expire on 31 December 2016, unless construction of the pipeline or the Kitimat Terminal has commenced by that date.” For reasons mentioned above, that is very unlikely.

So would this mean back to square one for Enbridge if shovels aren't in the ground by 2017?  Stalled for another...two...three...five years?
