ICE Canada canola futures fell on Tuesday in sympathy with broad commodity declines following China's devaluation of its currency. Oil, copper and other commodities tumbled after China's move, which raised concerns that a persistently weaker currency will choke demand in the world's top commodities consumer. November canola lost $3.80 to $507.60 per tonne. January canola shed $3.80 to $506.50 per tonne. November-January spread traded 2,665 times.
