Stone ground, unbleached white flour

Toast
Is there such a thing?  I remember reading that all flour will whiten if let sit over a period of time, something the commercial millers would not do because they have to get it out to the consumer too quickly.  I have never seen stone-ground white flour anywhere.  Might it be labelled "organic"?

I'm in Canada, Montreal to be exact, and I've never seen any stone-ground white flour except in Upper Canada Village, one of these heritage places showing life as it was over a hundred years ago.  I do remember the stone-ground flour from there, and even brought a bag home with me.  I'll have to do a search through health-food stores.
