Considering the direction of grain prices (actually all commodities) Canadian farmers are unsurprisingly looking to max out their planting acreage. No so much an interesting statistics, but in fact if you double the price of wheat farmers will increase their wheat production.
Obviously farmers have done their math, and the dramatic increase in fuel prices (and pesticide and fertilizer) still make the farming business attractive. Anyway, there you go, if you raise prices farmers like the rest of us will respond to price incentive.
