About Us

Located in the heart of south St. Catharines and established in 1958, Denis Morris Catholic High School is a vibrant and inclusive secondary school committed to academic excellence, faith formation, and community engagement. As part of the Niagara Catholic District School Board, we proudly serve students in Grades 9 through 12, offering a wide range of programs that support diverse learning needs, interests, and aspirations. 


Our school embraces diversity, enrolling students from our Catholic elementary schools - Our Lady of Holy Rosary, St. Anthony, St. Christopher, St. Edwards, St. Nicholas, St. Peter, and St. Theresa - and the broader public school system. 


We are proud of our rich history, named in honor of Rev. Monsignor Denis Morris, a beloved pastor of St. Catherine of Alexandria Church. His legacy of service and leadership continues to inspire our school community today. The school opened after his death and honors the values of faith, leadership, and service he exemplified. The Denis Morris Catholic High School community sees themselves as living extensions of his mission—creating strong, caring Catholic communities much like he did.


Denis Morris is known for its strong academic programming, rich co-curricular program and a deep commitment to student well-being. We have something for everyone here, whether students are interested in participating in clubs, student leadership, social justice, arts, or athletics. Rooted in Catholic values with Christ as our focus, our school fosters a nurturing environment where students are encouraged to grow intellectually, spiritually, and socially. Guided by our motto, Prudentia – Virtus – Intellectus (Wisdom – Virtue – Knowledge), we strive to develop responsible, compassionate, and faith-filled graduates who are prepared to make meaningful contributions to the world.


At Denis Morris Catholic High School, we believe in the power of Catholic education to transform lives and make disciples who are the future learners, followers, and doers of Christ’s teachings. We are dedicated to helping every student reach their full potential in mind, body and spirit, in a supportive, faith-filled environment.
