The elephant in the room and the inconvenient truth for politicians who traffic in this tin-foil absurdity is that the majority of the oilsands is not only foreign-owned, but the Majors have no problem getting their product to market because they are integrated with the refineries in Texas. And, why would they blockade their own interests?
Politicians like Kenney use conspiracy theorists like Vivian Krasuse (Canada’s own Kellyanne Conway: Queen of Alternative Facts) to achieve their own ends. Trafficking in conspiracy theories also deflects from Stephen Harper’s failure to consult Indigenous groups on Northern Gateway and Mr Kenney was Harper’s lietenant.
