The windows for the Day Chapel are a celebration of the life of Mary. It is hoped that the chapel will provide a place of contemplation, prayer, devotion, and peace for all who enter.

The Clerestory Windows are inspired by the book Mary's Flowers. The flowers chosen symbolize the life of Mary. In addition to the symbolic significance of the flower itself, the way it is drawn creates added layers of meaning. In the drawings there is a subtle suggestion of the Light of the Resurrection and new life.

The three apse windows are entitled "Images of Wonder". These windows, located behind the altar, are designed as a serene contemplative 'trinity' of windows, which evoke Mary by inviting us to enter into mystery, and into the realm of Heaven and Eternity. The intention is to convey the transcendent world beyond ourselves and our time. The flowing and connected images gather us in and allow for a deepened devotion. These contemplative windows also allow the focus to remain on the altar. The two side windows are conceived as flowing colours with quiet imagery connected to the altar windows and include text from the Magnificat.
