It's the connector flight. If somebody flies in from Brazil, they land in Toronto. They get tested. They have to wait to get the result before we let them get on another public conveyance of Canadians. If they show up at the airport, therefore, they're at risk of exposing others, because they're going to use other conveyances. So that's the GAA; that's the benefit for international air flights. If they're going to fly into the U.S., they have to land. They have to get a brand new PCR test right there. It has to be negative before they can even enter the country.
