- I've done a little checking, and I don't believe that such is required.
- Your use of "Her Majesty's Post Office" is rather suggestive, that if
- registration was ever required, it was a long time ago:
-
- - It hasn't been called HMPO for a *long* time. 50s or earlier I'd imagine.
- It's called Canada Post Corporation now. Unless you're referring
- to the *real* HMPO, but that's been out of the loop for an even
- longer time.
- - The post office wouldn't make much sense. Intelligence services maybe.
- The RCMP used to be responsible for such things as mail monitoring. But
- the RCMP has been out of that game for quite some time. CSIS (Canadian
- Security and Intelligence Service) took over intelligence services.
- - fishing expedition letter opening is probably not legal any longer, ever since
- the RCMP's "writs of assistance" were abolished. (a "WOA" was basically
- a portable search warrant that didn't need a judge - subject to many
- restrictions, but they don't exist any longer.) I think CSIS was
- split off after (or at the same time) WOAs were abolished.
- - In such a case now, the RCMP, CSIS or whomever would have to get
- a search warrant, which could be used to require the sender or recipient
- to supply the key.
-
- At one time the RCMP were quite paranoid about "coded" communications.
- One bizarre case was when the RCMP spent quite a bit of resources
- investigating two kids who were sending paper mail to each other addressed
- only by a social insurance number, street number and postal code for some fun.
- I don't think that they care much now, unless there's cause.
-
- I could just imagine what the banks would think of having to supply their
- ATM keys to the post office ;-)
