What does o.h.m.s. mean?
- O.H.M.S., an initialism for On Her Majesty's Service or On His Majesty's Service, is an official franking commonly seen on correspondence from government departments in countries of the Commonwealth of Nations, recognising Elizabeth II as their head of state. In Canada, O.H.M.S may be written on an envelope instead of using postage stamps for any letters being sent to the Canadian House of Commons or to any member of the Canadian Parliament. Letters sent from Lieutenant-Governors may also bear the O.H.M.S. mark.
