Kingston Collegiate and Vocational Institute (KCVI) was a secondary school in Kingston, Ontario, Canada. Founded in 1792 by Reverend John Stuart based upon a grant for secondary education in the colony of Upper Canada, it moved to its location at 235 Frontenac Street in 1892. It is considered the oldest public secondary school in Ontario and the second oldest in Canada. KCVI was Kingston's only public secondary school until the opening of Queen Elizabeth Collegiate and Vocational Institute (QECVI) in 1955 and Loyalist Collegiate and Vocational Institute (LCVI) in 1963. In 2012, KCVI was ranked by the Fraser Institute as the top performing school in the Limestone Board and in the top 10 per cent of public schools in Ontario. KCVI closed in December 2020, its student population moved to Kingston Secondary School, a new school constructed on the former QECVI site that was created to replace both KCVI and QECVI as the result of a Program and Accommodation Review Committee decision reached in 2014. History KCVI's history starts with the Kingston Grammar school in 1792. In 1807, the school was renamed Midland District Grammar School. From c. 1825–30, the future first prime minister of Canada, John A. Macdonald, attended the school. In 1853 the school moved to a new location (now Sydenham Public School) and was renamed Kingston County Grammar School. It was renamed Kingston High School in 1871, becoming Kingston Collegiate Institute (KCI) in 1872. Girls were first admitted as students in January 1877, and the school remained co-educational until its closure in 2020. Fifteen years later, at the institution's centenary in 1892, the school moved to its site on Frontenac Street. Finally, with the addition of a technical and commercial teaching wing in 1931, the school was renamed Kingston Collegiate and Vocational Institute (KCVI), the name it retained until its closure. The oldest remaining wing of the school is the 1915 wing, which housed science laboratories. The original wing was destroyed by fire but was replaced. The school celebrated its bicentenary in 1992 and celebrated its 225th anniversary in 2017. The school is commonly recognized as the oldest public high school in Ontario and the second oldest in the country. The school closure and move to former QECVI site was planned to happen at the end of the 2018–19 school year, but was then moved to happen in the middle of the 2019–20 school year. The school
