Catholic Central High School, named after the high school of the same name in Detroit, Michigan, was opened in September 1950 in what had been the Sacred Heart Convent. It consisted of grades XI, XII and XII. The Sisters of St. Joseph taught the girls and the commercial classes and the Christian Brothers taught the boys in the general classes under associate principalships held by Sr. Mary Angela and Brother Stanislaus respectively. By January 5, 1951, the Catholic Central sports teams had adopted the name Crusaders. The girls were known as Crusaderettes. It was about the autumn of 1952 that the words to the "Crusader Song" were composed by Barry McIlhargey, a grade XII student and football player. Meanwhile, the cornerstone for Sacred Heart Separate School, to the immediate west of Catholic Central High School was laid on December 8, 1951. By the time the school was officially opened on September 14, 1952, the school's name had been changed to Catholic Central Separate School (CCSS) and consisted of grades VII, VIII, IX and X. Sr. Elaine Dunn was its first principal. With the opening of CCSS, St. Angela's College, De La Salle High School and Sacred Heart Commercial closed their doors and their pupils were now absorbed into Catholic Central Separate School. The Christian Brothers also left London and Fr. Joe Finn, a diocesan priest, took Brother Stanislaus' place as associate principal. Father Dominic A. Kirwan, C.R. succeeded Fr. Finn in September 1952. In the fall of 1958 the construction of a new building for Catholic Central High School (CCHS) was begun to the west of Catholic Central Separate School. It opened for its first students in September 1959. In September 1963, CCHS was placed under the principalship of the Oblates of Mary Immaculate with Fr. Harold Conway as principal. The Board had first attempted to entice the Basilans to taken over the running of the school but the latter declined. In 1967, CCHS and Catholic Central Separate School, which for a number of years held only grade IX and X students, were joined under one principalship, with Fr. Conway as the first principle for grades IX-XIII A "tunnel" which was half above ground, was constructed to physically unite the two structures, which became known as the East Wing and the West Wing Owing to an increase in student population, a total of 14 portables were added between 1970 and 1972. The north wing which accommodates the Fine Arts & Family Studies programs was constructed in 1986.
