Halifax - More than 100 people will lose their jobs at Casino Nova Scotia in Halifax in the coming weeks and the casino will start closing for six hours a day later this month, a spokesman for the casino’s owner said Tuesday. Great Canadian Gaming Corp., based in Richmond, B.C., will cut 15 per cent of the roughly 800 full- and part-time workers, company spokesman Howard Blank said. He said 100 to 120 positions will go.
