It's simply a matter of etiquette, dignity & pride
With the firm revelation from Mr. McCreery that the Royal Canadian Navy and Royal Canadian Air Force continue to exist within the existing entity called 'Her Majesty's Canadian Armed Forces', that is to say that they subsist within the CF in the form of Maritime Command and Air Command, and given that Maritime Command is already being referred to as the Canadian Navy and Air Command as the Canadian Air Force, the recognition of the reality of the RCN and RCAF within the unified Forces should simply be done at the direction of the Minister of National Defence.
Indeed, it could be said that not using the Royal designation is, in fact, a breach of etiquette, if not protocol. The RCN and the RCAF were never abolished but re-organised. There never was any need for any reason to stop the use of the Royal designations with these forces as has been amply demonstrated with the welcome return of much of the traditional uniforms, ranks, et al to the Naval and Air forces.
All discussions related to this issue have now been rendered moot; including this petition to Parliament because it is not an issue for Parliament. The Royal Canadian Navy and Royal Canadian Air Force exist already with the Canadian Army within the CF. It is simply a matter of identification updating and restoration.
This should be done forthwith.
