Canadian Mysteries?

[enfant perdus]

I don't actually know if the patches are Canadian, except they came in a lot of Canadian items (barring one Australia title). The white over blue is similar to UK 1st Div signals, but I'm stumped by the 1 W.O. The red triangle I have no idea.

I know the CMR is Canadian Mounted Rifles and it has a Tiptaft mark. My question is about a) the lugs and b) usage. The lugs have very wide feet but appear to be original. Are these typical of Tiptaft titles? I've also been unable to find a comparable pattern in Chris Brooker's guide, so I'm curious as to which units might have used it.
