I'll start before I maybe pass it on to Dr. Tam.
In relation to the federal vaccination mandate, we have focused on multiple factors, as I mentioned earlier: the global and domestic epidemiological situation, vaccination coverage as well as the new variant of concern that is circulating, availability of rapid tests, as well as availability of different therapeutics. All of these things guide us to really see how far we can take it in terms of our ability to have those who are unvaccinated come to work.
Again, at this point, the federal vaccine mandate is specifically a function of Treasury Board Secretariat, and we have almost 99% coverage for the public service employees—at least.
