Thank you very much.
In terms of the Canadian model—I don't want to call it that, because I don't think it originated from us. There are 20 other countries doing it and I think the U.S. is moving to it as well. In terms of the rapid testing, does the infrastructure exists? I don't have up-to-date figures and I take you at your word. We've heard from Transport Canada officials, or I have anyway, that the numbers are way down. I know that an airport is a big space and our land borders.... Do we have the capacity to do these rapid tests? At what point do they stop being effective? Have those discussions taken place?
