In terms of airline workers, we're aware of five airline workers who have contracted COVID. We're aware that there are 200 in isolation. Are we aware of how much of that is related to the repatriation of Canadians and the fact that they were coming from areas with high infections and we were working night and day to evacuate Canadians to safety? How many of those isolations are directly tied to rescuing Canadians and have nothing to do with masks? Even if you had a mask, you would still be in isolation. The mask wouldn't prevent you from getting COVID. It may prevent you from spreading it.
