Canola futures suffered heavy losses to begin the week on weakness in Chicago soybean and soybean oil futures.
The two US markets fell to their lowest in seven weeks amid uncertainty over US biofuel policy and rising trade tensions between the US and China after each country accused the other of undermining the terms of a mutual tariff pause struck last month.
July canola lost $24.30 to $686.80, and November was down $20.70 at $667.90.
