Thank you for the question.
Our services could have been better used by having us actually do the job we're there to do at the border.
In terms of enforcing public health measures, the only requirement we saw being fulfilled through the ArriveCAN app, practically, was showing that someone was vaccinated. Again, that could have been done by someone showing us their phone or a printed-out piece of paper that showed that they were vaccinated. All the additional questions, time and difficulties people had.... You mentioned elderly people, or people without the technology available to them or who simply didn't understand a lot of those questions, which, to be honest, were complicated for somebody who doesn't work at the border. In many cases, there wasn't any need for any of that, which takes away the need for the app altogether.
The few officers we have at the border should have been concentrating on doing their border officer work, rather than on that.
