The Old Mill Heritage Centre, located in downtown Kagawong on Manitoulin Island, used to be a pulp mill providing paper for Sears Roebuck catalogues in Wisconsin. Now it houses an Art Gallery, the municipal office and the Old Mill Heritage Centre Museum. The Old Mill Heritage Centre has a Multi-Media centre with different themes from Agriculture, Military, early sawmills, commercial shipping and fishing, life in Billings Township and of course the story of the Daniel Dodge Tragedy. A gift shop features "Island of Great Spirit", a video History of Manitoulin Island. This site is also home to the former Spring Bay pioneer Post Office donated to the Kagawong Historical Society in 1992 by Harold and Reverend Mary Jo Tracy. It was relocated to Kagawong by the Kagawong Historical Society in October 1993. Once used as a homestead, it was moved to the Old Mill Heritage Site in 2008.
