The department has investigated the advantages and disadvantages of doing this to the runways across the Northwest Territories. One of the cons of this whole thing is, if we were to even do this, say, in the northern region, put chipseal down and the chipseal peels up, it could cause delays on those runways and disrupt service to them; but the other side of it is the cost of the equipment that would be needed to repair these. We're not going to go out and buy paving equipment for each community to be able to address this thing.
Based on performance around that, Transport Canada does not treat runways any different if they are chipseal paved versus gravel, so there's no advantage to doing that. I believe the Province of Saskatchewan has done this and we are working closely with them and seeing what they have done, because they've already returned a number of those runways that they did back to gravel.
