Though it is a Roman Catholic school, the student population has Catholic and non-Catholic components.

Expansion
The school was founded in September 2001, with an initial enrollment of 750 students. The school outgrew the main building's original capacity of 1,000 students and an annex was built to accommodate the increase in enrollment. Construction for the annex began in 2006. John Burroughs, the principal at that time, expected enrollment to peak in the following years. The addition was ready for use in September 2007 with ten classrooms, a food services classroom and a conference room in the southwest corner of the school.

On October 25, 2013, a fire was deliberately set in a girl's first floor washroom. Damage was totaled to be over $75,000.
