All politics all the time.  The prairies have been written off by Liberal political poker.  85% of the carbon goes out the tail pipe, 15% in the production of oil.  Yet we tax the export of oil and subsidize the production of cars.  Only makes sense when you look at the map and population density.  The only thing we are doing now is exporting production (plus jobs, plus exports, plus....) to places that will happily produce the oil but have far less concerns about human rights and the environment.  We are exporting misery.  Of course this is too complicated for the 130 character tweet that JT and the jets will make to justify all this.
