Centre Wellington District High School, or CWDHS, is a fully composite high school located in Fergus, Ontario. The school was originally called Fergus High School and was constructed in 1928. Later, two additions were built, but eventually, the number of students exceeded the capacity of the building. As a result, a brand new school was built which opened in September 2004. It is run by the Upper Grand District School Board. The principal of the school is Janine Grin; the school's vice principals are Kevin Taylor and Lynne Vink.
