Thank you very much for your question. It's quite a good one.
That's something we discuss frequently with our colleagues and other agencies.
If we get word from the province or a health care provider that somebody has been diagnosed positive for the coronavirus, if they provide us that information, we can go into our databases. Working with our colleagues at Immigration, Refugees and Citizenship Canada, we can look at databases to see, for instance, whether you applied for a visa or whether you have a Canadian passport. We can find those individuals who were sitting within proximity of that individual on the plane; I think it's within two metres that we're concerned about on a plane.
The quick answer to your question is that, if we get the name of the positive individual, we can take that information through our databases. We can identify who was within close proximity on the plane when they arrived in Canada.
