The Deputy Grand Chief of the Nishnawbe-Aski Nation says Ottawa must do something about the teachers living quarters in Pikangikum. Terry Waboose says the teachers need to return to Pikangikum as soon as possible so students don't lose the entire school year. Pikangikum leaders say nearly all of its non-local teachers have left the community because of mould in the teachers' residences. And they say that's jeopardizing the school year for hundreds of students.
