ETOBICOKE, Ontario – Stakes fields of modest size, unfortunately, were the main order of the day Thursday, with six entered in Sunday’s Woodbine Mile, seven in the Northern Dancer, and six in the Ontario Derby. But the Canadian Stakes had fared better when the entry box closed Thursday, as a field of nine fillies and mares was unveiled for the Grade 2, $300,000 turf race at 1 1/8 miles.
