After the Cadet Corps inspection on May 11, 1956, the Memorial Entrance to the Memorial Classroom Building was dedicated to the memory of the Old Boys who lost their lives in the Second World War. Their names are inscribed on a tablet which was unveiled by David Guest, eldest son of the late J.S.H. Guest, Appleby's co-founder and first Headmaster. The dedication was performed by Reverend Dr. Nicol of Knox Presbyterian Church, Oakville. A First World War Honour Roll was also added to the Memorial entrance.
