Where to find minerals in Canada:

I usually buy everything from the local feed store (Buckerfields is one of them, I also buy from a commercial outfilt called Evergrow in Victoria. also Integrity Sales in Victoria ), and there are some stores out here on the West Coast that are more organically oriented and have a better selection (Borden Mercantile in Victoria, for instance). Many of these stores are able to source special products
You can get almost anything online from the Organic Gardener’s Pantry in smaller quantities.
