I'm not really sure what the fuss is about. In fact, Air Canada is hiring from a wide range of experience levels, and a good number of the new recruits are going to be people who have a university degree but can barely qualify for an ATPL. There were several relatively low-timers in the first 2 courses.
There are several good reasons for this. One, people with minimal experience are more accepting of the lower pay rate that now lasts longer than the good-old 2 years of pain we remember from the past. Also, they will need people with education to fill management roles in the future. Contrary to what's being said, AC is not being swamped with resumes from experienced high time jet jockeys and jockettes from the likes of Westjet, Transat and Sky. Many of those people see AC as a major step back both in pay, and in future prospects for a lifestyle better than they currently enjoy.
