We've looked at a number of things with respect to mobility of workers. There doesn't seem to be a silver bullet in terms of an incentive to get workers.
We know firms right now are doing it. There are amazing things going on with the oil sands in terms of construction workers from, I think, Newfoundland flying to the oil sands, but it's all being done at the firm level.
One of the issues is that when you get into government trying to do that kind of incentive for workers, it becomes a bit of a double-edged sword. You could say there are all these skills shortages in Alberta and you might have high unemployment in another region of the country; therefore, why are you not providing incentives for them to move? Well, some of those other regions of the country get pretty upset when there is an active encouragement to lose skilled workers they would like to maintain.
So while we have been looking at a variety of incentives, there hasn't been a real inclination to put them in place at this point, because a lot of people think it would probably be too much fettering in the labour marketplace.
