The Grey Nuns Mother House

The Grey Nuns Mother House is associated with the Grey Nuns of the Cross and was originally used as an infirmary, convent, and orphanage. The Grey Nuns Mother House is still in use as a convent today.

The Congregation of the Sisters of Charity at Ottawa, also known as the Grey Nuns of the Cross arrived in Ottawa in 1845, under Mere Elizabeth Bruyere, to render nursing services to the needy. The Order went on to establish the Ottawa General Hospital. The Grey Nuns Mother House was constructed in several phases; the first phase was completed between 1849-1851, an orphanage on the north part of the building in 1867, a central wing connecting the two previously constructed buildings in 1889, and an addition of a fourth storey in 1937.

The site eventually evolved into the Ottawa General Hospital, a Catholic hospital intended to offer care without regard to age, sex, language or religion. The Ottawa General Hospital was relocated to a new site in the 1980s but the original building is now known and used as the Elizabeth Bruyere Health Centre.

The Grey Nuns Mother House is associated with several architects who completed different parts of the building between 1849 and 1937. The original structure was designed by Antoine Robillard and initially consisted of a three-and-a-half storey limestone structure. The addition on the second storey of a matching pair of sundials, in 1851, was designed by Father Jean-Francois Allard, a geometry teacher. These sundials marked the first public timepiece in Ottawa and are considered to be unique in North America. Between 1935 and 1937, a fourth storey was designed by architects Werner Ernst Noffke and Lucien Leblanc, in an Art Deco-influenced style, which they also used in their designs for the adjacent Ottawa General Hospital.
