Thank you, Madam Chair.
Maybe I'll just ask Ms. Potter a follow-up question on her last point. She said, if I understood correctly, that having an alternative option for people who struggle with the technology or who don't have access to the technology would have avoided a lot of the problems we saw at land borders and air borders. I appreciate that this is sort of a retrospective on how things could have been done better.
Separate from the question of whether the vaccine requirement was appropriate, given that the government put the vaccine requirement in place at the borders, do you feel that having the app as an option as opposed to a requirement would have avoided a lot of the challenges we saw?
