I'm certainly not a public health expert. My understanding is that several tests have been approved for Canada and there are others on the way. As I was referring to earlier, some places are administering a more accurate PCR test a couple of days prior to departure and then combining that with an antigen test.
We really need to move to having conversations with our colleagues from the air carriers about how to do this. We've been looking to advance discussion on this aspect since the spring. We are now having these conversations, but we don't have a lot of time ahead of us if we are to rescue Canada's tourism sector next summer. As people are getting vaccinated and as pent-up demand for travel starts to materialize next year, we think we're going to see Canadians wanting to travel and other people wanting to travel. We want to make sure they can do so and feel even safer with a test.
