I would say that Transport Canada, with evolving regulations, continues to require masking while on a plane and in secure areas of an airport as a protection measure, and that's based on evidence. I don't have a sense that it materially affects the flow rates through the airport. It's not an issue where we feel there's a problem we had to solve with our industry partners, where something was being slowed down because of the fact that people are wearing masks.
I don't know if Denis or any of my colleagues might have a comment on that.
