Canada's oil industry faces a year of "tough slugging," including the deferment of many projects, as oil prices collapse to as little as US$30 a barrel then likely stabilize around US$70 to US$75 a barrel, oil entrepreneur Murray Edwards predicted Friday. Because of its high costs, the Canadian sector will be impacted more than many oil-producing jurisdictions around the world by OPEC's decision Thursday to not cut oil production, said Mr. Edwards, the chairman of Canadian Natural Resources Ltd. and one of Canada's single biggest oil investors.
