WINNIPEG, Manitoba, Jan 31 (Reuters) - Canada, the world's biggest canola grower, is running short of the oilseed six months before the next harvest, with strong export demand driving prices to nearly 13-year highs last week.

Supplies of major commodity crops are dwindling worldwide as buyers hoard food supplies during the COVID-19 pandemic. China is loading up on grains and oilseeds that it can feed to animals, raising food inflation and causing some nations to restrict exports of their crops.
