ICE Canadian canola futures ended flat on Tuesday, after earlier touching a nearly three-week high for the nearby contract, lifted by strength in soyaoil.
Rising canola margins are also underpinning the crop's value, but prices are held back by other brisk farmer sales of last year's crop, a trader said.
May canola ended unchanged at $467.50 per tonne. Deferred months were slightly higher. May-July canola spread traded 3,515 times.
US corn futures bounced from multi-year lows as farmer sales ground to a halt, while soybeans edged higher.
