In terms of questions for the witnesses, thank you for being here.
One of the things I've been trying to get my head around on this issue is where the urgency for this request has come from. My understanding is that in annual reports by Air Canada, for the last couple of years, intense labour costs for maintenance aren't listed as a problem for the company. There's no suggestion the company is in financial trouble because of excessive maintenance costs. Can you give us a sense of why those issues weren't mentioned if this is an urgent problem?
