A remote First Nation in northwestern Ontario is still working to recover from "unprecedented water levels" coming from the Pikangikum Lake, according to an emergency management official with the community. Major infrastructure and the main source of drinking water in Pikangikum were threatened by the rising water earlier this week, and the sole road to the northern store — the only place community members can purchase food and gas — was covered with water. The remote First Nation has about 3,000 residents and is located 500 kilometres northwest of Thunder Bay, Ont.
