Mr. Chair and honourable member, earlier some discussion came up on this topic. We're very seized with preparing for having a significant number of people who are fully vaccinated and how we will adjust and respond at the border, and then there's a longer term issue of the international arrangements to allow Canadians who are vaccinated to go to Greece, or wherever—the internationalization of that issue. That work is also under way.
As Dr. Tam was saying, it's difficult to nail it down a specific date, because there are a number of things that we have to watch. That includes better understanding of whether the people arriving still can be carrying infection even though they've been vaccinated previously. We still need to understand that better before we can go too far.
