It includes the communities of North Bay, Parry Sound, Mattawa and the Almaguin Highlands.

The NNDSB was previously known as the Parry Sound and Area School Board.

In 2006, three former students filed lawsuits against the NNDSB for the sexual abuse they suffered at the hands of Kenneth Bull, a former teacher of the school board.

Bull taught at Humphrey Public School, where the assaults occurred.

The school board was named in the lawsuit for its failure to protect the students.
