According to Major Louis E. Grimshaw's book The Badges and Insignia of the Canadian Airbone Forces; "This shoulder title was apparently designed by Major Randy Routh, who was also involved in the design of the cap badge and who later commanded the training centre at shilo. The title, authorized 8 April 1943, is dark green melton cloth with white embroidered lettering, and is found in two varieties, one having shorter letters than the other. The titles were first issued at Shilo in 1943 .................... Although the Battalion changed its shoulder title the following year, it is presumed that the "AIRBORNE CANADA" title remained in wear at the school in Canada." Hope this helps.
