I will "hazard " a guess most pipelines have been shut or cut down . as the producer's can't get the diluetent that is needed to make the heavy oil flow ? I see Fort mac as the absolute vitale hub to the oil sand's. where everything the producer's need either get's flowen into or is staged ? waiting delivery. Shipping from edmonton is null and void Where do you think the supplies be it food to heavy equipment come's from or through?? I lived in whitehorse for 5 year's every part we needed came from vancouver or lucky if edmonton had it? Still 2 day's out !
