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 has since subsided to 800 students.
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 programmes, all embedded within a community that celebrates its Catholic faith first and foremost. The school has a double gym, fitness room, library, computer labs, performance stage and an indoor track.

The purpose of St. Thomas Aquinas Catholic Secondary School is to present the Catholic tradition and teachings in all our pedagogy to prepare our students to meet the demands of modern life within the context of the gospel.
