Found some documentation for the Canadian Scottish embroidered shoulder titles, 1st Bn. They were submitted for approval May 27, 1941. An order was made shortly after.
The Canadian Scottish were an anomaly in the organization of the army in Canada during the Second World War. Most units were organized on a two battalion basis during the war. There was the Active battalion and the reserve army battalion. There were a few units, like the Regina Rifles, Régiment de Maisonneuve, Fusiliers Mont Royal, Irish Fusiliers among others that had three battalions. In their cases, the 3rd Bn was an active battalion, and the 2nd was a reserve army battalion. Only active battalions were entitled to wear coloured embroidered shoulder titles. The reserve battalions were only authorized to wear the worsted or khaki drill slip ons. (Though a couple of exceptions exist. Sometimes the reserve Bn's received titles intended for the active unit, and sometimes they acquired titles at their own expense, but without permission.) So, for most units the first battalion was the active battalion and the second was the reserve battalion.
However the Canadian Scottish was one of the few units which had two active battalions. This explains the issue of the two patterns of coloured embroidered shoulder titles. The Canadian Scottish 1st Bn was overseas, and the Canadian Scottish 2nd Bn was mobilized for service in Canada Jan 1, 1941, served with the 6 Division and was disbanded October 15, 1943. A third battalion existed, and was the reserve army battalion. The 2nd Battalion Canadian Scottish, as an active battalion in Canada, were entitled to a coloured title, but not to the pattern of the 1st Bn. The only Battalion entitled to wear the oak leaf acorn pattern badge was the 1st Bn. Thus the THE/ CANADIAN SCOTTISH pattern.
