Thank you.
NAV CANADA controls air traffic. It's a completely independent organization, and because there are no planes in the air, it is losing about 80% of its revenue. The situation is improving slightly, but like any organization, it has debts to pay. So it had no choice but to increase rates, by 29%. This is another indication of the difficulties facing the airline industry in general.
In some cases, there are discounts because there are almost no services. So there are discounts in terms of the hours when services are provided. However, I can assure you that this goes through Transport Canada and that decisions made by NAV CANADA will not compromise safety.
