Introduction

Established in 1956 with the motto "Post Proelium Praemium" (After the struggle, the reward.), Thornhill Secondary School has undergone significant expansions to accommodate its growing community. The school's original structure was enhanced with key additions, including a technical and commercial wing in 1961, a library in 1964, and a science wing in 1998. The school also boasts various facilities, including an art lab, student council office, cafeteria, auto lab, and weight room. It also features a communication technological lab, a family studies lab, a design & technological lab, a drama stage, gymnasiums, a food lab, music rooms, a resource center, student parking facilities, a science lab, a yearbook office, and a darkroom. Additionally, the school has an outdoor track and fields.

Aligned with the curriculum standards set by the Ontario Ministry of Education, TSS offers a diverse range of co-curricular activities to enrich students' education. The school prioritizes the overall well-being of its students through programs like Healthy Eating and Active Living (HEAL), Healthy Active Mornings (HAM), and Drop Everything and Read (DEAR). Moreover, TSS actively promotes character education within the York Region District School Board. Initiatives such as Peer Mediation, Peer Tutors, Community Outreach/Clubs, and  fundraising for various charities contribute to fostering a positive and supportive school culture.
