You're absolutely right.
The key is to get as many people out of the line as possible. Multi-entry visas are probably the best way to do that, and trusted traveller programs and electronic travel authorization.
It's effectively pre-screening people before they get on planes to come here in a more efficient manner. I think you can set up different criteria. I would worry that we could set up too many criteria. If there are too many categories to fall under, it might make things more cumbersome. But I do think there is a role for that segmentation.
Let's be frank. We have a trading partner in the United States. One of the points to the Beyond the Border process was to harmonize some of these issues with the United States. We've now done that. We're sharing information. There's very little reason why someone who has a 10-year multi-entry visa to the United States shouldn't be able to use a short form to get a short-form visa to come to Canada. Since we're already sharing that information, that's a very easy efficiency to the system, and one that's happening between countries like the U.K. and Ireland.
