You mean these ones?
If Pips and Crowns are fine enough for the Antigua and Barbuda Regiment, The Fijian Regiment, or the Papua New Guinea Land Element, it's fine enough for the Canadian Army. Even Republics that swapped the Crown for something else use the Order of the Bath as their "pips"
Contrary to popular belief, we are not a tin-pot, Caribbean or African Republic's armed forces. Our nation is was one of the first and largest members of the Commonwealth and thus makes sense we retain some vestiges of the Crown. This concept of "Canadianizing" our identity (which was already Canadian, through the identity of the Commonwealth we profited and help build) stemmed from the ridiculous "not British" sentiment coming out of Quebec in the 1960s.
Funny how in 2025, when we see a "not American" identity emerging, His Majesty gets an invite to read the Speech from the Throne, and there are more units looking to head to Horse Guards for a couple of weeks.
