Obviously, both Canadian and American officers have a duty to protect border safety and security as well as that of travellers and of course themselves, airport staff, and other port staff. We don't think someone should be required to answer questions on withdrawal, as you know. That's not currently the case. People are free to go if they want to go.
First, that isn't to say that they couldn't have questions asked of them. You don't need to detain someone to ask them questions. CBSA officers could also ask people questions without detaining them or requiring them to stay. They're entitled to do that.
Second, we suggested in our remarks just a few minutes ago and in our submission that there is a way of trying to narrow this down. If we say we're really concerned about people perhaps endangering security or testing the pre-clearance site, what have you, then find a way of tailoring the obligation to stick around to those circumstances. Right now, it's open-ended. They don't need to suspect anything at all. They just decide they want to do it.
We're concerned that over time that may be used in a discriminatory manner. It may be used in manners we don't yet understand. If that's our real concern, let's find a way to narrow it in the legislation so they are detained properly with a reasonable suspicion of something, and deal with it in that way.
