Help identifying CA brassard

[MacNav63]

Been sorting through stuff in my basement and came across this brassard. It was my Grandfather's so Great War or later vintage. I'm guessing Second World War as he had a series of staff jobs during that one. Any help identifying it would be much appreciated.

Thanks! That would make sense since I believe he played an Adjutant-General role of some sort as major at Camp Borden.
