Canada Post had a key in the browser list for a decade or so, and there was
some project with Entrust to do something, but I don't think it ever
happened.
I also don't understand why I have a scanned PDF from ic.gc.ca as a corporate
identity, and not a PKIX certificate. They've had all the software to the
PKIX key for 20+ years.

The post-office is unique in that it can get a letter to many people within
24h, rather cheaply, and I keep thinking that this is a better 2FA (or 3FA) for
account recovery.

Canada Post is among the most technologically incompetent organizations ever.
They are captive for big consulting companies, and I think that the big
consulting companies couldn't figure how to turn such an effort into a profit
center for *them*.  I figure that is the reason.

Maybe Amazon has the clout with the Post Office to make that happen :-)
[I say with only half tongue-in-cheek]
  "Alexa, please renew my certificates"
