Welcome to Father Donald MacLellan Catholic Secondary School, we focus on the guiding principles that you seek in quality Catholic education: Excellence, Equity and New Evangelization. We welcome students of all faiths at our secondary school. We offer 21st century learning, academic results, faith formation and a safe, caring community that accepts and respects your child.


Our faith

Students embrace the Catholic Church's renewed efforts to meet the spiritual needs of today's society, as witnesses to the Gospel values in their everyday lives.

Yes, Catholic schools are different. Each student in our Catholic learning community embodies excellence and equity by embracing the Ontario Catholic School Graduate Expectations - to be:

  • A discerning believer;
  • An effective communicator;
  • A reflective, creative and holistic thinker;
  • A self-directed, responsible lifelong learner;
  • A collaborative contributor;
  • A caring family member; and
  • A responsible citizen.

People choose Catholic schools as an extension of their families. They want the values taught at home to be witnessed and lived at school. This is precisely what we offer in a Catholic school community.

Contact us

If you have any questions about yours or your child(ren)'s education, contact your teacher or a member of our administrative staff. We're committed to helping everyone achieve success. Call us at 905-666-1146.
