CGCS opened in 1977 as a port-a-pak complex with five classrooms, one bathroom and a combined staff and storage room. When student enrolment increased, a second port-a-pak unit was added. The CGCS students were bused to the Our Lady of Wisdom School for gym class and library time. When the CGCS opened, its staff consisted of ten members: Robert Laplante, Susan Rheaume, Rosina Davis, Colleen Plante, Norma Menard, Georges Lajeunesse, Martine Bealne, Faye Powell, Betty Sharland, and Dan Charbonneau In September 1979, CGCS opened its new school building. The school also became the first home to the new Divine Infant Parish. Father Michael Hurtubise conducted the first English Catholic mass in the CGCS gym. After two year, the parish moved its functions to St. Matthew High School. Prior to CGCS' current principal, D'Arcine Thompson, there were seven other principals. The first principal was Robert Laplante. Following in chronological order were Joanne LaPlante, Dr. Margaret McGrath, Joan Gravel, Robert Benning, Paul Wubben, and Patricia Morden-Kelly.
Current status
CGCS is now home to more than 300 staff and students, including 27 teachers, principals, custodians, and librarians. The school day starts at 9 am and ends at 3:30; there are three recesses, two snack times and a 45-minute lunch. The parent council organizes an optional paid 'hot lunch' for the students every Friday.
CGCS students wear burgundy and grey uniforms. The schools logo consists of a cross with a "C" and "G" overlaying each other, surrounded by the school's name "Convent Glen Catholic School". CGCS provides boys and girls touch football, basketball, and volleyball tournaments.
