 Grey Highlands Secondary School (GHSS) was built in 1967 as one of the many new school construction projects undertaken by Education Minister Bill Davis in order to modernize and centralize rural elementary and secondary schools.When it opened in September 1968, it became the central high school for students from three smaller district high schools, covering a collection area of 195,000 hectares (750 square miles).Those smaller high schools were converted to elementary schools, which in turn replaced the many one- and two-room school houses that were still in operation until that time.
