Canada’s largest oil producers are calling on the Alberta government to reward companies that commit to adding crude-by-rail capacity by easing their oil curtailment levels. The proposal would allow crude oil export capacity to increase at the same time that barrels are being produced to fill that capacity, Suncor Energy Inc. CEO Mark Little said, while taking part in a panel discussion with representatives of four other large Calgary-based oil producers at the TD Securities Calgary Energy Conference. The result would be that Alberta producers would be able to get better prices for higher volumes of oil, which would swell the government treasury with more resource royalties and taxes, he said.Bombardier Inc.
