Highly encouraged but not required for employment.
Obviously required for Canadian entry and by a large minority of our owners who now have it in their crew notes that vax is required. Have flown a few who required negative rapid tests in addition to vax prior to their arrival at the airplane but their security details have handled that, not the company.
If you're still unvaccinated you're required to test prior to each rotation but I'm not sure the logistics behind how that happens.
Thankfully I'm 'woke' enough to not have to worry about that. Somehow the most dangerous part of my vaccination process has been listening to the non-vaccinated pilots tell me how dangerous the vaccine is on a constant basis. At least my 5G coverage has never been better while I pretend to listen to them complain about something they won't do. Win some and lose some, I guess.
