In the 1840s prior to the designation of school sections, a school was built between Hyndman and Campbell's Corners. The first schoolhouse was constructed of log, and a decade after its construction had fallen into disrepair. By 1852, the community had been designated as a school section which was shared with Hyndman, known as S.S. #17. The log schoolhouse was replaced by a frame structure with brick veneer built at a cost of $430 including the land purchase; the school was referred to as S.S. #17 Campbell's Mills School. When the school was rebuilt, it was also relocated further west along Hyndman Road at the corner of the road leading to the Campbell family's mill. In 1875, Hyndman and Campbell's Corners were divided into two school sections; Campbell's Mills School remained S.S. #17 and used the existing schoolhouse, while Hyndman became S.S. #23 and required a new school. In 1914, S.S. #17 underwent minor renovations inside and outside; the structure was covered with clapboard and the furniture and interior floor were replaced. In 1964, the school closed due to lack of enrolment caused by improvements in transportation and the construction of larger, modern schools nearby.
