An abrupt downturn in an already poor water-quality situation in a northwestern Ontario Indigenous community poses more of a safety risk than the federal government is willing to acknowledge, representatives of the First Nation said Wednesday as they called for help covering the cost of evacuating the community. Most of the 250 residents of the Neskantaga First Nation, a member of the Nishnawbe Aski Nation, flew out of the community on the weekend after untreated water began flowing from local taps and water pressure tapered off dramatically.
