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 ;-)
