École secondaire catholique Thériault

École secondaire catholique Thériault is a secondary school located in Timmins, Ontario. It is a Francophone Roman Catholic school administered by the Conseil scolaire catholique de district des Grandes-Rivières with some 1000 students. The school is named after Père Charles-Eugène Thériault, one of the founders of the city of Timmins.

The school was established in 1968 through the amalgamation of Collège Sacré-Coeur, Collège Notre-Dame, and l'Académie Don Bosco. Its current building was finished in 1972 and features various facilities, including the Agora, a common area, a cafeteria, a 750-seat auditorium named after Charles Fournier, a former vice-principal, two gymnasiums, and a track and field complex. Notably, the auditorium is the largest in the city. At its peak in the late 1970s, the school had close to 2,000 students, making it the largest francophone secondary school in Ontario at the time. The cross-country running program, led by Frère Roland Saumur, has achieved numerous team and individual championships in NEOAA (formerly I.A.G.B.) competitions, as well as winning several OFSAA medals. Additionally, the school offers various sports programs, including badminton, curling, volleyball, wrestling, among others. To commemorate its milestones, the school hosted a reunion for its 15th anniversary in 1993, and the Class of 1988 celebrated the 20th anniversary of their graduation with a reunion in August 2008.

The current principal is Chantal Bourgon. Alain Bédard and Luc Meunier are Vice-Principals. The school has hosted such pan-Ontarian francophone events as Les Jeux Franco-Ontariens (2006) and the improvisational provincial tournament known as "L'Association franco-ontarienne des ligues d'improvisation étudiantes" (1989, 2000).
