The Public Health Agency has indeed issued guidance through the Canadian aviation sector. We have been working with airports, looking at increased measures, such as social distancing and non-surgical mask requirements. That guidance is available on our website. We are working closely with Air Canada. We continue to pay attention to what's happening at airports.
Currently, the volumes are very low. If the volumes were to increase to a level higher than they are now, certainly some of those measures would become more challenging in maintaining social distancing at all times. The fact that the wearing of the mask is a requirement is contributing to reducing the risk.
From the Public Health Agency of Canada, we have also increased our presence at airports and at border crossings.
