Well, we have. CATSA Plus employs technology, but it's also procedural changes. There is some capital investment required, and CATSA has a plan to roll that out at the highest volume airports. Unfortunately, budget 2017 has stalled that, so it's only partially implemented in Toronto, Montreal, Calgary, and Vancouver, I believe, at the moment. For example, you're probably not seeing it at Toronto Pearson. I know they have it at the transborder connecting to the U.S. It's dramatically improving the traveller experience, and that's why it's one of the recommendations we have, that investment be restarted.
In a volume-based business, though—6.3% this year alone, a 10% increase in international travellers—efficiency and technology are going to do a lot, but you still need the bodies on the ground as well. It's a volume-based business; there's no way around it. We're innovating to do more with less, but the resources do need to keep up.
