That shouldn't be a problem at all.
Let's start with immunity passports. I think we need to poll the Canadian public, because there are very polarizing thoughts on this. I can certainly see some benefits and obviously some clear drawbacks, and especially some major equity issues with that.
With regard to surveillance on airplanes, I would see this as a public-private partnership. That's essential. We know that human mobility is responsible for so much of the transmission of infectious diseases nationally and internationally. Look at our non-existent influenza season we're having so far. I don't want to get too overconfident, because it's just the beginning, but we can see how human mobility significantly contributes to the spread of infectious diseases. Public-private partnerships, through some formal program that we can think of, be it the IATA or whatever, need to happen.
In terms of priority populations, I completely agree with Dr. Chagla. While front-facing individuals who are part of the essential functioning of society should be prioritized—that includes teachers and other members that Dr. Chagla mentioned—that certainly could include crew. That would be below the priority of people at risk of severe infections such as those in long-term care facilities, indigenous populations and other groups that were mentioned in the NACI guidelines as the first tier of people who should be vaccinated.
