ITEM 8.01. OTHER EVENTS.

       On December 6, 2010, SunOpta Inc. (the “Company”) issued a press release announcing that its indirect wholly-owned subsidiary, SunOpta Fruit Group Inc., has signed definitive agreements to acquire 100% of the assets and business of Edner of Nevada, Inc. (“Edner”), for cash consideration of $4 million, on a debt-free basis, subject to post-closing working capital adjustments, plus a potential earn-out dependent on the achievement of certain future targets. The transaction is expected to close in the next several weeks upon the completion of customary closing conditions.

       Edner was founded in 2003 by Ed and Vicky Kirschner and produces a wide variety of nutritious portable foods such as nutrition bars and grains and fruit based snack bars serving the fast growing wholesome and convenient healthy snacks category from its 104,000 square foot facility, located in Carson City, Nevada. Edner co-packs for a variety of branded and private label customers and current revenues are approximately $10 million, with equipment and capacity available to support an increase of revenues to approximately $50 million without significant capital investment. Edner's existing operational capabilities would also enable the Company to extend the breadth of its fruit based product offerings via the introduction of innovative new products utilizing the capabilities that exist within this facility.
