How short people's memories are.  Harper approved Northern Gateway in 2014 and the courts reversed that  in 2016. What is all the talk about Trudeau doing something that the Conservatives couldn't do. Under Harper TransCanada's Keystone pipeline (not to be confused with Keystone XL), Enbridge's Alberta Clipper, Kinder Morgan's Anchor Loop pipeline and Enbridge's Line 9 reversal, were all completed.  Just because Kinder Morgan was approved in no ways means it will be built. Notley has NOT received political points from this, unless you already were a supporter. She is gone 2019. There is too much wrong with this government and this just ain't gonna fix it.  She is polling in the teens and Trudeau can stand on his head and spit wooden nickles, it no longer matters. She is done.
