Leadership

School leadership ensures that the school facilities, pedagogy and activities of Loyola create an environment that is conducive to our students becoming intellectually competent, religious, loving, open to growth and committed to doing justice. They support our caring and dedicated faculty and staff to model what is means to be men and women for others.

    President

    For the past 125 years, the school’s mission has never wavered from the vision of its founding community: to educate young people to change the world through a life formation that focuses on forming the “whole person”. In Jesuit education, the road to academic excellence extends far beyond the confines of the traditional classroom.

    Care for the “whole person” means ensuring students are not just intellectually competent, but that they are open to growth, loving, religious, and committed to doing justice. It means ensuring a balance of intellectual, physical, mental, and spiritual well-being.

    For over 125 years, Loyola has fostered student engagement both inside and outside of the classroom. The competence, commitment, compassion, and conscience they have are nurtured by their involvement in all aspects of school life. They carry these qualities forward into life outside the school walls -- with their families, friends, communities and workplaces, and ultimately -- the world.

    All of that starts here. The care and experience of our Faculty and Staff, our alumni and older students, provides an environment for Secondary 1 students that is immediately welcoming, stimulating, exciting and will change your child’s life and your family forever.

    As our students say, “It is the ride of a lifetime”.

    Comme le disent nos étudiants, c’est « une aventure hors du commun ».
