Holy Cross Catholic Secondary School opened its doors to students and staff in September of 1990. The facility was blessed by Archbishop Francis J. Spence in the official opening ceremony on October 28, 1990. The school on Woodbine Road in Kingston’s west end boasted 110,000 square feet with a state-of-the-art technology wing, lecture theatre, gym, and classrooms ready for the challenges of the 1990s and beyond. Growth continues to be a hallmark of Holy Cross. In 1998 a second gym was added to the facility as well as a permanent addition of two stories with sixteen much-needed classrooms.

Holy Cross is well known for its successes in academics and the arts. Holy Cross prides itself on its commitment to service. The school is able to offer an extensive and diverse curriculum. Students have an opportunity to take traditional subjects, but can also challenge themselves in the arts or technology. The school offers many extra-curricular activities including band, drama club, Students' Council and a community service group. Holy Cross students and staff are proud of their accomplishments and school. The slogan, "Once a Crusader, Always a Crusader" rings true for every graduate from Holy Cross.
