That did come up in Washington on our trip. I've made notes on American officials' suggesting that they've already been asked about expanded border services on a cost-recovery basis that would cost Canadian travellers more, because it would be passed on. It was raised on our trip. I could see a little bit of the light going off in their eyes in terms of more cost recovery. If they were to provide those same services on their own soil in a non pre-clearance operation, they would be doing it in those airports.
Now, I could argue that you're going to get charged by an airport in either end of your destination. I think there's some work, though, that needs to be done on that.
