ICE Canadian canola futures weakened on Tuesday, settling back from a rally on Monday amid good crop conditions in the fields, traders said. Some farmer and commercial hedging ahead of harvest added to the weakness. Traders also said that strength in the Canadian dollar was weighing on the market and further chilling already weak export demand. November canola fell $2.90 to close at $465.60 per tonne. January canola dropped $3 to $472.00. November-January canola spread traded 2,552 times.
