St. Andrew's College, also known as SAC, is an independent school founded in 1899 located in Aurora, Ontario, Canada. It is a university-preparatory school for boys in grades 6 to 12, with a focus on academic achievement, athletics, and leadership development. It is accredited by the Canadian Educational Standards Institute and is affiliated with other associations, including CAIS, CASE, NAIS and the International Boys' Schools Coalition. St. Andrew's College was first situated in Toronto on land east of Old Yonge Street over to Bayview Avenue, in a house named Chestnut Park that was previously owned by Sir David Macpherson. In 1905 the school moved to Rosedale, and made its final move to the current campus in Aurora in 1924. The school has a 110-acre (0.45 km) campus suburban environment. Its Georgian architecture is built around the traditional quadrangle form. There are four boarding houses on campus which are home to one half of the approximately 560 boys. Many teaching faculty also live on campus. St. Andrew’s College's Arms were registered with the Canadian Heraldic Authority on August 15, 2006.
