Yes. The change, really, is to allow us the time to assess the risk before the people come to Canada.
We of course would like to identify the threat on foreign soil and not have them come to Canada. That would of course be the optimal situation. Even if we don't have the ability or don't get the approval to do something like that, identifying the threat while they're en route and being able to address it as soon as they land here on Canadian soil is of course one of our key objectives.
