I have never seen this badge before or anything remotely similiar. While this is a post-war photo the badge is probably from a wartime unit or formation.
General H.D.G. Crerar attending an investiture in Winnipeg, Manitoba, 13 January 1946. (L-R) an unidentified Corporal of the RCASC; General Crerar; an unidentified Captain, probably RCA. PA-209539-v6.jpg
I'm refering to the black cloth badge on the Captain's left arm. It appears to be three witches flying upwards towards the photo's left. Can anyone identify?
This photo is from the LAC "Faces of War" online exhibit.
