A fight over which horse won a Canadian Derby race in Edmonton two years ago is to be heard in court this week. Queen’s Bench Justice June Ross is to look at the results of the Aug. 19, 2017, race at Northland’s Park. Chief Know It All was originally declared the winner despite a complaint from the owner of another horse it allegedly fouled. Ten months later, the Horse Racing Appeal Tribunal disqualified Chief Know It All and named two other horses, Double Bear and Trooper John, as co-winners.
