Kouign amman in Quebec (Montreal) - can it be found
I've heard Les Co'pains d'Abord makes one sometimes, but I've never seen it (as I don't go often).
And I've heard great things also about the one at La Porte (restaurant). The chef is from Bretagne I think.

Le Kouign Amann makes a somewhat updated version which is a bit lighter than the traditional kouing amann. I know there are more traditional versions out there, but I can't recall where I've seen them.
It has been discussed before, so doing a board search with the proper spelling of kouign amann might prove fruitful.
