AC is hiring a lot.
Yes they are hiring from the regionals, but currently the majority of new hire pilots are coming from other operations, primarily with jet experience. I have seen several new hires from overseas carriers.
If you have the right to work in Canada, and jet airline experience you have an excellent chance of being selected.
Life is generally good at the airline. Lots of types and variety depending on what you wan to do. Join as a FO on 767/737/320/EMJ or RP 777/787. Junior upgrades are about a year right now in Toronto on a EMJ, 2-4 years on the 737/320... FO 777/787/330 is a few years at least. CA on a widebody... who knows, much is changing and will change before the day comes - call it 20 years.
Good luck.
