Building 7, also known as the Memorial Building, forms part of a complex of three structures, which includes a chapel and a workshop, situated near the parade ground. They are attached by a 19th-century protective wall. It is a small, rectangular, one-story masonry edifice with a pyramidal stone roof and a row of windows on all four elevations. Its principal façade is distinguished by a modern porchway. Governor General Georges Vanier and his wife Pauline Vanier are interred here at the commemorative chapel.
