You'll find the answers on there, just check in the Air Canada and WestJet sections.

One thread near the top of the AC forum has the retirement numbers listed in it.

As far as I know, WestJet has barely any retirements for the next 5-7, but then a decent number start retiring. Most hiring there right now is fueled by growth.

The tribunal for the age 60 ruling with Air Canada recently came to a conclusion.. age 60 rule stays status quo for Air Canada. WestJet you can go as SIC till 65, and that's the same situation with Jazz I'm pretty sure.
