I've gotten berries from several places over the years. In Vancouver I had got some from Famous Foods. In Chilliwack at Anita's Mill. In Agassiz Cedar Isle Farm. They are a co op and you have to get on the list and pre order.
On the Island Vancouver Island Grain and Milling Port Alberni.
Online from Fieldstone, Storehouse, 1847. There's quite a few more online suppliers too. When you have to pay for shipping it can suck so look for free shipping if you spend a certain amount. I sold sourdough for a little while too before moving to the island and I did a wholesale purchase from Snow Cap once.
My next quest is to try to source some berries from Italy.
