I've never doubted that Mr Trudeau is a staunch environmentalist, that that is his priority over carbon-based energy development.  He aligns himself with the young, and so it's environment over development, if he must choose.  For every pro-pipeline statement he's made he makes many more about going off carbon.  And aside from his words, his actions (or inactions regarding carbon-based energy projects) so far make me even more sure of my assessment of his loyalties.
