FYI, the general and flag officer ranks:
One star/maple leaf: RCN - Commodore (Cmdre), CA - Brigadier General (BGen), RCAF - Air Commodore (A/C)
Two star/maple leaf: RCN - Rear Admiral (RAdm), CA - Major General (MGen), RCAF - Air Vice-Marshal (A/VM)
Three star/maple leaf: RCN - Vice Admiral (VAdm), CA - Lieutenant General (LGen), RCAF - Air Marshal (A/M)
Four star/maple leaf: RCN - Admiral (Adm), CA - General (Gen), RCAF - Air Chief Marshal (A/CM)
Unlike Britain and America, Canada never had five star/maple leaf rank, but if ever it did happen, it'd probably be this:
Five star/maple leaf: RCN - Fleet Admiral (FAdm), CA - Field Marshal (FM), RCAF - Marshal of the Royal Canadian Air Force (M/RCAF)
But given the unified nature of the Canadian military and the leaning towards American-type traditions in recent years (ever since Unification in 1968), the five star/maple leaf rank might go this way:
RCN - Admiral of the Forces (AdmF), CA - General of the Forces (GenF), RCAF - Air Chief Marshal of the Forces (A/CMF)
