Lots. I have flown and continue to fly with a few Americans who have come north of the border, and I've worked with plenty more who decided to move back Stateside. Pilot hiring in Canada is still strong, although the delays from Boeing are certainly going to be felt into next year, which may slow things down, but I doubt it to a point where it stops. That is especially so at the commuter and charter operators who, according to Mrs.+TSRA who works for a charter company, are hiring pilots they would never have given a second glance pre-pandemic. She says any good, experienced pilot will find no problems gaining employment.
The biggest issue you'll find is that starting at the bottom of the list at an airline, it'll be awhile until you see the left seat. I know a few people may call out to say Air Canada is upgrading at 3 years seniority right now, but they're all late 20s and early 30s, so once those spots are filled, the upgrades will go back to 10-15 years. My gut tells me that'll happen in about two years or so once the AC retirements begin to slow down. WestJet is sitting at 9 years right now, 12 for reserve out of Calgary, but who knows what the merger with Sunwing will bring. We'll know better on that front end of October when the merged list drops from the arbiter. Porter is flying high right now, but we'll see what the potential closure of the Island airport in Toronto does with them. I wish them nothing but luck, but they're edging on the typical Canadian growth story of too much, too soon. Air Transat seems to be in a touch of hot water with some layoffs announced (no pilots), but my guess is a trip through our bankruptcy court will set them in the right direction. And then there is Flair. If you listen to anyone in industry (myself included), they'll likely not be around in a year. But that year is now 5 years long, so they continue to prove all us experts wrong. They've got the quickest upgrades in town for the airlines, and I'll admit their reserve seems sweet - taxi an airplane from remote parking to the terminal and call it a day. But I still wouldn't stake my career on them.
