A First Nation community in northwestern Ontario that has been under a boil water advisory for more than 25 years says it is evacuating some of its members after a new issue with its water supply was discovered. In a tweet just before 5 p.m. ET, Neskantaga First Nation Chief Chris Moonias said it is “disheartening and sad” that he has had to evacuate the elderly, infants, chronically ill and vulnerable people from the community for a second time during his tenure.
