Records relate to the establishment and operation of the Lakehead Unitarian Fellowship in Thunder Bay, Ontario. They reflect matters concerning Port Arthur, Fort William, and Thunder Bay; and the development of Unitarianism and its institutions in North America more broadly.

The LUF is a non-profit organization that was incorporated into the Canadian Unitarian Council in 1984; after incorporation, the materials become more formal and there is more paperwork pertaining to the fellowships organization and governance.

The material includes reports, correspondence, newspaper clippings, photo negatives, floor plans for building, pamphlets and brochures, and several CDs, which included photographs and videos from special events. Majority of the materials are LUF specific, while there is also material pertaining to neighboring Unitarian organizations in Canada and America, and to the broader Unitarian Universalist Association\ Canadian Unitarian Council. Some records are specific to individuals while others relate to the entire fellowship.
