Thank you for all that! I knew King had been on one of the bigger denominations, but with the frequency at which the Bank of Canada has changed the bills in recent decades I wondered if King was still on one of the notes. I heard about Macdonald being replaced by Canada's own Rosa Parks, so that's very cool!The Bordens. WWI era PM Borden is on the 100$ (brown) bill. King is on the (red) 50$. Elizabeth (soon Charles) is on the (green) 20$ and all coins. Macdonald was on the (purple) 10$ bill but has been replaced by Viola Desmond. Laurier is on the (blue) 5$ (smallest bill denomination). Far enough back and the monarch was the face of multiple, perhaps all, bills (old Canadian currency is not among my specializations in history).
In Quebec it’s far more customary to refer to the bill colour than the name. Can’t speak to the rest of the country on this point (in my 40 years here, I’ve lived 36 of them in Quebec).
I think Terry Fox is also slated to go on a Canadian banknote?
