That policy will be evolving, because there haven't actually been that many fully vaccinated travellers. Canada is still in a very difficult situation with the third wave. Our domestic vaccination rate is still catching up and is accelerating, but I think part of the decision-making related to vaccinated travellers has to take into account the global as well as the domestic epidemiological situation. We're still learning about the reduction in transmission.
