The origins of the St. Catharines Collegiate Institute can be traced back to the formation of the Grantham Academy on Church St. in 1829. In 1845, the name was changed to the St. Catharines District Grammar School and in 1890 the Grammar School was renamed the St. Catharines Collegiate Institute. The current site of the school on Catherine Street was built in 1923 to accommodate the increasing demand for technical education, and became known as the St. Catharines Collegiate Institute and Vocational School. The school was enlarged with additions in 1945, 1965 and 1969. In 2006, the school underwent major renovations, which were completed in 2008. It is currently a secondary school administered by the District School Board of Niagara.
