No idea what they they will be but we can have some fun trying to guess.
So far, there has not been any flying or aquatic animals. What quintessential Canadian bird can we put? Only two really come to mind. The Loon and the Goose. I think we have had enough loonie coins this year, so if it had to be a bird, I'd say the Canadian Goose.
As for an aquatic animal, I'll skip the obvious one for now. We've got Atlantic & Pacific Salmon. Of course, on a coin, most fish kinda look the same. And there is always the obvious Beaver. Its been a good 5 seconds since I have last seen a nickel.
Need some more ideas? Plenty of other choices here:
