Canada is a wonderful case study. There is no mandatory retirement age for Canadian airline pilots. However due to ICAO, some Canadian carriers have a requirement to retire at 65 and even 67. And some can fly beyond that, just not in international or U.S. airspace.

Canada has also already indicated in no uncertain terms that if the FAA increases the mandatory retirement age from 65 to 67 that U.S. pilots WILL NOT be able to fly in Canadian airspace as this would be a violation of ICAO. Sssoooo that means that airlines would have to plan around pilots/routes that encroach on Canadian airspace (DTW approaches etc). We don’t even have certainty that 65+ pilots would be able to fly to Hawaii because that is through ICAO airspace.

This whole thing is an absolute cluster ******* in the making and the pro 67 crowd knows it and are full steam ahead regardless. Unreal.
