Subdivided geographic TLDs are still common in Ontario govts, such as gov.on.ca [1] and tdsb.on.ca for Toronto schools.[2] Both are still in common use.

I love the old interent. I'll confess I have three locality domains and they are wonderful.
I'll confess I have successfully registered a locality domain this year (2025) and it was a little bit fun to go through the weird hoops to get this new domain registered.
I'm also working on/helping out a registrar whose owned died and his widow is resolving what to do with the non-profit.
A related quaint couple of blogs[1][2] if you're feeling nostalgic and motivated to register your own:
