School History
St. Thomas Aquinas was built in 1994. The school building constitutes 152,314.31 sq. ft., and the site encompasses 8.180 hectares. St. Thomas Aquinas Catholic Secondary School is located in the north-west sector of London, Ontario, adjacent to a popular subdivision known as “Byron”. The school was built with the expectation that it would house 945 (“on the ground”) students. Its peak capacity hit approximately 1800 students (in the late 1990’s), and currently, 1200 students are enrolled.
The school is well known throughout South-Western Ontario as a school with a proud tradition of strong academic focus, tremendous athletic successes, and magnificent artistic performances and programs, all embedded within a community that celebrates its Catholic faith first and foremost. The school has a double gym, fitness room, library, performance stage and an indoor track.
