As for your second question, can certain countries restrict entry to people if they have not been vaccinated? Yes, we are aware of that happening. We received information from the Department of Foreign Affairs to the effect that Saudi Arabia, for example, is going to require people entering the country to provide proof of vaccination. Certain countries are making such requests. It is a possibility. But we will not do that in Canada.
