It's working to its limits, and if there's one key point I want to make today, it is that if we don't reinvest in the system, it's very hard to grow it. Trusted traveller programs have worked to a limited degree, NEXUS being probably the most successful. But there isn't enough promotion behind it, and it's getting difficult to get interviews. It is being consumed by its own success because of the lack of investment.
As mechanisms, they're really important, because, as I said earlier, that's what gets people out of line. Whether it's that or even the innovative stuff that CBSA is doing through ABC kiosks at airports, whatever we do to facilitate the process makes us more competitive.
