The Thornbury Independent Order of Oddfellows received their Charter in October of 1884 and in 1936 they purchased the lodge building on Main Street in Thornbury. The upper level of the building became the lodge hall and half of the main floor has been home to the Thornbury Bakery for many years and the other half in later years Studio 16. Over the years the loge has supported various local charities along with fire and accident victims. For many years the lodge put on a New Year’s Eve dance at the Thornbury High School, which is now the elementary school. At a provincial level, the I.O.O.F. lodges support summer camps for kids with Cancer, one being Camp Trillium. The lodges also support an eye research program through the University of Toronto as well as Leukemia research. In the past few years, membership in the Thornbury lodge started to decline and as existing members started to age, a decision was made in 2008 to close the Thornbury lodge and amalgamate with Spirit Rock lodge in Wiarton. At this time the lodge building was sold. The remaining members of the lodge now had the responsibility to disperse of the lodge assets and the main objective was to keep the money within the community. Donations at this time have been made to the installation of a new audio system in the arena, the Beaver Valley Outreach, the Beaver Valley Athletic Association, the Beaver Valley Pre-school, the Thornbury theatre group, the Marsh St. Centre, the Golden Beavers and the Community Family Health Centres.
