Registration

At the Durham Catholic District School Board, we believe that education is more than academics - it's about nurturing the whole student: mind, body, and spirit. Our schools are grounded in Catholic values, fostering compassionate, inclusive, and faith-filled learning environments where every student is inspired to reach their full potential.

We welcome families to register at our school at osas.dcdsb.ca.

To register for specialized programs, such as the Regional Arts and Media Program (AMP) and French Immersion, or Adult and Continuing Education programs, please explore the webpages in the side menu.
