We haven't done that analysis. What I will say is that if the fees and taxes levied on Canadian passengers were reduced, one could reasonably assume that more Canadians would fly, and there would be more flights because it would be a more accessible product to sell. If they were reduced concurrent with the introduction of a competing service, I think it's very difficult to predict what the outcome would be. There's certainly an argument to be made for the train as far as convenience from a security perspective. If you're offering downtown-to-downtown service, we would see if aviation could compete in that circumstance. There would certainly be an effect, absolutely.
The other thing I will say is that if you reduce those fees and taxes, it does help to perhaps generate passenger traffic coming from out of the country. We can then connect that on down the network. For visitors to this country and long-haul traffic originating in Canada, there is a tangible effect from that fee structure. One would certainly hope that we would be more competitive with our neighbours to the south.
