High Quality Content by WIKIPEDIA articles! O'Neill CVI is the oldest secondary school in Oshawa, opened in its present location in 1909 as Oshawa High School. High school classes had been held in the Central Public School downtown for many year prior to this, so the school's roots go back well into the 19th century. The 1909 OHGS building is still in the core or the school, but is not visible from outside. After several major expansions during the 1920s, OHS was became Oshawa Collegiate and Vocational Institute in 1930. In the Post-war era, when Oshawa began building other high schools, OCVI was renamed O'Neill Collegiate and Vocational Institute after long-time principal, Albert O'Neill, who had led it's expansion and transition to collegiate status. O'Neill celebrated its 75th anniversary (as OCVI, though it's actually much older when the OHS days are included) in 2005 with a large mural in the library and a huge reunion of students and teachers.
