Holy Cross High School opened in September, 1963, using three borrowed classrooms in St. Charles Elementary School, and serving only Grade 9 classes. The following year, the first wing of the present school building was ready and Grades 9 and 10 students were accommodated. Instruction in Grade 11 was added in 1965-1966, and Grade 12 in the following year. In June, 1967, the first Holy Cross Grade 12 class graduated.
From these beginnings, modest in size and numbers, but rich in spirit and enthusiasm, Holy Cross High School has grown to be an important force in education in our city and in our province.
