Appleby College is an international independent school (grades 7-12) located in Oakville, Ontario, Canada, founded in 1911 by John Guest, a former Headmaster of the Preparatory School at Upper Canada College. Guest dreamed of establishing a small boarding school in the country, and did so with the support and financial assistance of Sir Byron Edmund Walker, a prominent Canadian businessman and patron of the arts. Today, Appleby is a co-educational day and boarding university-preparatory school, with a curriculum based around the liberal arts. It is situated on Lake Ontario in Oakville, Ontario, roughly 50 kilometres west of Toronto. Students are drawn primarily from Oakville, Burlington and Mississauga, but boarding students come from other parts of Canada and throughout all continents of the world. Appleby is a member of the G20 Schools, the International Round Square Organisation and the Canadian Independent Schools Athletic Association. Appleby is accredited by the Canadian Educational Standards Institute. On October 13, 2006, Maclean's Magazine named Appleby one of Canada's Top 100 Employers. Appleby is the first high school ever to receive this distinction.
