To Jesus through Mary

Immaculate Heart of Mary School is a private Catholic school dedicated to the Mother of God and taking its name and spirit from the writings of Saint Louis Marie de Montfort’s “True Devotion to Mary.” All subjects are taught in the light of the Faith, striving to form the whole person as a Child of God destined for Eternal Life.

The Sisters MICM (Slaves of the Immaculate Heart of Mary) teach Grades 1–8 at the Elementary building and the Brothers MICM instruct Grades 9–12 at MacIsaac Hall across the road.

Living Tradition

IHM students are blessed to attend the Latin Mass daily and to enjoy the full benefits of Traditional Catholicism by frequenting the sacraments.

Dedicated to Mary

We promote Total Consecration to Jesus through Mary among the students. As one priest friend once said of IHM, “Our Lady walks these halls.”

Academically Excellent

Quality Catholic education encourages discipline and high standards that form the soul, mind and body to achieve success in time and eternity.

Expansion Project

The IHM Expansion Project will almost double the number of students attending Grades 1–8! There is a crisis in education in today’s world, especially for Catholic families who want their children surrounded with the same morals at school that they teach at home. With your help, the new addition will soon provide many more souls the gift of a Traditional Catholic Education!

The Catholic Future

Every gift towards the IHM Expansion Project supports Traditional Catholic Education and our Catholic Future!
