All units of the Canadian Armed Forces have an order of precedence that determines seniority; it often decides such matters as which unit forms up to the right (senior side) of other units on a ceremonial parade, or the order in which marches or calls are played at a mess dinner.
Note: 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. RCA units parade to the left of units of the Royal Canadian Armoured Corps.
