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.
