NTCS belongs to the Edvance Christian Schools Association, and this organization has a sports program in which the school is active. This provides opportunities for NTCS students to compete with students from many Christian schools in southern Ontario.
The school is also involved in the TDCAA (Toronto District Colleges Athletic Association) and the SSAF (Small Schools Athletic Federation) for some of the senior high school sports teams.
For high school students, intramurals take place throughout the year. Teachers organize a variety of sports played between competing teams within the school. Any student can join, and activities include basketball, dodgeball, ball hockey, table tennis, soccer, and volleyball.
