The Community Assembly of Vancouver Island is located on an island in the north eastern Pacific Ocean and part of the Canadian province of British Columbia. The southern part of Vancouver Island and some of the nearby Gulf Islands are the only parts of British Columbia or Western Canada to lie south of the 49th parallel. The southeast part of the island has one of the warmest climates in Canada, and since the mid-1990s has been mild enough in a few areas to grow Mediterranean crops such as olives and lemons.

Indigenous peoples have inhabited Vancouver Island for thousands of years, long before the arrival of Spanish and British naval expeditions in the late 18th century. The Spanish and British conjointly named it Quadra's and Vancouver's Island in commemoration of the friendly negotiations held in 1792 between the Spanish commander of Fort San Miguel in Nootka Sound, Juan Francisco de la Bodega y Quadra, and British naval captain George Vancouver, during the Nootka Crisis. (Bodega y Quadra's name was eventually dropped.) It is one of several North American locations named after George Vancouver, who between 1791 and 1794 explored the Pacific Northwest.
