Authority was granted in February 1943 by His Majesty's Stationery Office to publish the "RAF March Past" piece in Canada under the title "RCAF March Past". It was the official march of the Royal Canadian Air Force until the unification of the Canadian Armed Forces in 1968. Following unification, the march was authorized for use in the Air Operations Branch, and further authorized as the command march of Air Command in 1975, later renamed back to its historic name as the Royal Canadian Air Force in 2011. The RCAF March Past continues as the official march of the RCAF. It is also the official march of the Royal Canadian Air Cadets and the Air Force Association of Canada.
A pipe band arrangement was composed in the 1950s by Pipe Major Alex Howie of the CFB Trenton Pipe Band, and a trio for pipes was composed in 1970 by Pipe Major Archie Cairns.2
The following are the lyrics to be sung to the Trio section of the march (composed by George Dyson). It references the motto of the RAF, "Per Ardua Ad Astra" (Latin, "Through adversity to the stars").
