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 his father-in-law, Sir Byron Edmund Walker, a Canadian businessman. 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 one of two Canadian members of the G30 Schools. It is also a member of the International Round Square Organisation and the Canadian Independent Schools Athletic Association. Appleby is accredited by the Canadian Educational Standards Institut
