When I look at those other designs, all I can say, is what were some people thinking? Stars on a flag for Canada? Seriously?
Thank goodness we got the flag we did - it's so different and striking from almost every other flag on the planet.

I remember having a group of business guests here one late October for a conference and golf. I was driving a guy around from Edmonton who, I don't know, had never been here before. We're roaring along and he sees a flaming red tree, about the colour of our flag and he went "WOAH!!! What IS that SPECIES?" We stopped and it was, of course, a sugar maple ... just like the one on our flag. Guess what folks, it really is flaming red for a time each year . This is a subtlety that a lot of us miss. It is a little less stylised than a lot of us may have known.
That's odd, he must never have been to the north end then.
97 Street bordering on the former CFB Griesbach (now a housing subdivision) is surrounded by maples (red, orange and yellow) and is a favourite spot for photos every fall here in Edmonton.

He had me bring the car to a screeching halt.
I would be surprised if you have sugar maples in Edmonton. They were certainly introduced, if so and I'm very surprised that they've survived the Alberta climate. They are almost "Carolinian" and they stop abruptly at the southern rim of the Shield.
