I can't give you any precise numbers because we're still collecting all these numbers, but the impact is that it's slowing down our recovery, of course. That's our concern here; it's our ability to serve the travelling public.
A comment I want to make, which complements what's been said, is that whether airlines or Nav Canada or CATSA, they had to send home about 50% to 60% to 90% of their personnel during the pandemic. You're bringing back all these people, and that requires training.
I think Nav Canada let go 700 flight controllers. You can't hire these people off the street. They require training. It's the same thing with CATSA. It's the same thing with our pilots. When an airline lets go 90% of its pilots, some of those people will just not come back to the industry, and when they do come back, a lot of retraining is required. All of this slows down the process of recovery.
