Canola is renowned as Canada's most profitable crop, exported to China, Japan and Mexico to make vegetable oil and animal feed.
But in March, Beijing revoked the licences of Canadian exporters Richardson International and Glencore Plc's agriculture unit, Viterra Inc., slowing China's overall purchases amid a broader diplomatic dispute.
Canola futures are down three per cent year over year in the world's biggest canola-growing country despite severe harvest problems that normally would lift prices, adding further pressure to declining farm incomes.
This year will be remembered as the "harvest from hell," said farmer John Guelly, chairman of the Alberta Canola industry group.
Canola's problems may even frustrate some from sowing it next year, he said.
"I think there will be a pullback in acres for sure."
Comment: Meanwhile in the United States officials are using the word 'disaster' to describe the widespread crop failures happening there.
