The Central Okanagan Heritage Society (COHS), a Federal charity and a Registered BC Society, was formed in 1982. The Society began when a committed group of concerned citizens rolled up their sleeves to save and restore the historic Benvoulin Church. Over the past thirty-six years, this work has continued with conservation of and advocacy for other heritage sites including Guisachan House and gardens, Brent’s Grist Mill and through the annual Heritage Awards.

Today, the Society has two part-time staff, a seasonal part-time gardener and a site caretaker and operations are assisted by a volunteer Board of Directors, volunteers and its members. The Society owns three heritage buildings: Benvoulin Church and Reid Hall, McIver House and McDougall House, and works with the City of Kelowna and community groups to conserve and rehabilitate other heritage sites and buildings and to educate the community about the importance of heritage. COHS also manages the City of Kelowna Heritage Grants Program and advises homeowners on conservation of their heritage homes.

The Central Okanagan Heritage Society's Mission Statement is:

The Central Okanagan Heritage Society promotes conservation of the diverse heritage buildings and sites of the Central Okanagan through stewardship, education and collaboration for the benefit of current and future generations.
