Having your own domain and giving a unique email address to everyone... Is it correct to call this canary trapping email addresses?

Sounds about right. Yes, I've been doing it for decades now and besides telling you who's selling email lists, it makes filtering much easier. Filtering by To: is pretty low effort compared to Bayesian spam filters etc. They get tossed in a Sieve filter as soon as they become a problem, and I'll send a bitch letter to the leaker with another random email address to see how dedicated they are to screwing me.
How is this possible for any normal person with a work provided 365 account?
You can use the +label method on M365 work accounts, like first.last+label@workdomain.com
Outlook rules match on them too, for rules.
