Bulk bread flour in Nanaimo, BC?

Anyone know if there's some place in Nanaimo or nearby where one can procure unbleached bread flour in large size bags (20kg)?

We just moved here and don't quite have the lay of the land yet nor know if this sort of stuff is unavailable here on the island. I would like to presume there is a source since there are a number of bakeries who would need wholesale supplies too.

Thanks for any heads up you can give.
