Trudeau "supports" the oilsands but wants to add regulations to their carbon outputs through an environmental regulatory scheme (aka a way for the Feds to take a cut of profits and send down east).
Note that he doesn't have any of the same "support" for Ontario based high carbon emitting manufacturing centers, or any other environmental issue.
There are scant details, only talking out of both sides. He wants to support the oilsands, but limit their growth through a yet to be detailed regulatory scheme and grab a chunk of revenue.
