John McCrae Secondary School

John McCrae Secondary School is a public secondary school in the Nepean district of Ottawa, Ontario, Canada. It supports grades 9-12. Built in 1999, it is the primary public high school in Barrhaven, replacing its predecessor, Confederation High School. John McCrae Secondary School is attached to the Walter Baker Sports Centre, and thus, attending students have several activities and amenities available to them, such as squash, swimming, weightlifting, and a library.

The school is built on a hill in a residential neighborhood in old Barrhaven and is named after Lieutenant Colonel John Alexander McCrae, MD (November 30, 1872 – January 28, 1918), a Canadian poet and doctor during World War I who wrote the poem "In Flanders Fields".

Up until 2016, the school performed a musical every other year. Past years' musicals have included Lucky Stiff, Zombie Prom, High School Musical, "The Butler Did It, Singing," and Back to the 80s. In 2015, the school performed its last musical for 11 years, Hair.
