Where to find minerals in Canada:

  • Local feed stores. Buckerfields is one of them.  Also a commercial outfit called Evergrow in Victoria. Also Integrity Sales in Victoria. 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.  http://www.gardenerspantry.ca/
