The date or which a service was formed generally has little to do with precedence which is more concerned with tradition and history, regular or reserve force. The Royal Canadian Navy is the senior Canadian service because we take our military traditions from the British; since Britain is a sea-faring nation and the Royal Navy is their senior service, then so is the RCN senior in Canada. Therefore when looking at the three branches of the Canadian Armed Forces it is Navy, Army and Air Force.

Within the Army; Armour, Artillery and Engineers are the top three corps due in part to their prestige and technical acumen. Within the Armoured Corps there is an order of precedence with RCD, LdSH and 12 RBC being the first three, they are also regular force; this is followed by reserve regiments starting with the GGHG all the way to the Windsor R (RCAC).

Looking at the Infantry, the three regular force regiments are senior in the order consisting RCR, PPCLI and R22eR this is followed by the reserves with the GGFG being senior all the way to the R Nfld R. I would suspect that if CSOR is on this list then it would fall in after the R22eR in the spot once held by the Canadian Airborne Regiment.

For a parade this order is tweaked a little. The honour of "the right of the line" (precedence over other units), on an army parade, is held by the units of the Royal Canadian Horse Artillery when on parade with their guns. On dismounted parades, RCHA units take precedence over all other land force units except formed bodies of officer cadets of the Royal Military College representing their college. Royal Canadian Artillery (generally reserve) units parade to the left of units of the Royal Canadian Armoured Corps.
