Discover our School

Our school respectfully acknowledges that we are located on the ancestral, traditional and unceded Indigenous territory of the Algonquin Peoples,
on whose territory we pray, learn, play and work.

The OCSB acknowledges the suffering experienced by Indigenous peoples in Canada's Residential Schools and is committed to Truth and Reconciliation. Read the OCSB Response to the Truth and Reconciliation Calls to Action to learn more.

The Learning Commons contains many features which the students and staff are encouraged to make use of to work, to study, to collaborate and to learn: 

The library staff provides research and technology assistance along with a welcoming setting where students can create a social learning space for group and individual study.


St. Mark Catholic High School is privileged to have its own Chapel. The Chapel is the focus of the spiritual character of the school and is used for private prayer and class liturgical celebrations. Our Chapel is a warm, peaceful refuge where students, staff, and parents are invited to pray, reflect, and rejoice. The chapel is open daily for all students and staff.

Chaplaincy Department

Our school's current Chaplaincy Leader is  Ryan Ellis.

Our school community and every student and staff member have gifts for the building up of this community. As part of the community, the chaplain works closely with others in the school to assist in the general education of students within a spiritual framework. Celebration and service, two key elements of the spiritual life, are integral to the life of our Catholic school. The chaplain, in conjunction with students and staff, assists in the animation of these areas. The chaplain is available to both the students and staff through retreats and spiritual counselling.
