Indigenous Services Minister Marc Miller is preparing to launch a third-party investigation into the business practices of consultants and engineering companies hired to end Canada's longest-standing boil water advisory — a probe that could extend to other communities, CBC News has learned. "The problem is we have a system for delivering infrastructure that always goes with the lowest bidder," Angus said. "When you have a big-ticket item, like a water plant that's very expensive to build in a community, costs and corners get cut and that's the danger. Neskantaga has been a nightmare situation."
