All land-based activities (crop and livestock) must undergo a transition period. The Canadian Organic Standards must be applied to a production unit for at least 12 months before the first harvest of organic products, and proof must be provided that prohibited substances have not been used on the land for at least 36 months. After the receipt of all forms and payment of initial application fees, the operation is considered under the supervision of PACS and the 12-month transition period begins upon that date; during which time an initial inspection and certification review will take place. Following a second successful inspection, and after the 12-month transition period, crops qualify for organic certification status.
