The first is that you can't rely on people doing the right thing totally, so there has to be a consequence past that. We have to make sure there's a full continuum, from telling people the rules and reminding them nicely to reminding them forcefully, and then we have to ensure there's a follow-through.
I know the CBSA has made efforts to increase enforced removals. Part of it is the threat of no return visa. To be really candid and direct, we have to make sure that's a real threat. We have to make sure that IRCC is applying that rigorously and then use that to nudge people to do the right thing.
To go back to the question about culture change, we can't fully rely on people to do the right thing. I think we want to create opportunities for them to do the right thing. I think we want to create an environment that incentivizes them to do the right thing, and then I think we also have to be clear that if they don't leave in the first instance, then there is a second and a third instance where more aggressive actions are taken.
