Brentwood College School is a co-educational boarding school that focuses on preparing students for the challenges of post-secondary education. This school is located on Vancouver Island in Mill Bay, British Columbia, Canada. Brentwood was first founded in 1923. The original location was in Brentwood Bay near Saanich on Vancouver Island, from where its name was derived. The original school was destroyed by a fire in 1947, leaving only the chapel intact. The current school is located westward directly across the bay from the original site, in Mill Bay. The new version of the school opened in September 1961. In 1972, Brentwood College became the first all boys' boarding school in Canada to gradually integrate girls, starting with 20 grade 12 students, becoming officially co-ed for the fall session.
This oceanfront school has tennis courts, rugby fields, eight student residences, two academic buildings, a rowing boat house, laundry facilities, a cafeteria, a sportsplex, and a health center.
