Description of Historic Place

Mother House of the Grey Nuns National Historic Site of Canada is a large, austere, stone building located in downtown Montréal, Quebec. The rectangular, central portion of the building features a distinctive, elegant chapel with octagonal tower and spire. Regularly placed windows and dormers give an ordered appearance. The main portion stands four stories tall except the west wing which has five stories. The building stands on an H-shape footprint with entrances on Saint Matheiu and Guy Street. The Guy Street entrance features a gatehouse. An ornamental metal fence and a stone wall surround the grounds that contain treed gardens, paths, seating and statues. Official recognition refers to lot at the time of designation.

Heritage Value

Mother House of the Grey Nuns was designated a national historic site of Canada in 2009 because:
- its monumental scale is a tangible manifestation of the breadth of work carried out by the Grey Nuns in service to society – particularly the elderly, abandoned children, orphans and the sick – here in Montréal and in their missions around the world;
- begun in 1869 after the Grey Nuns of Montréal had outgrown their first home at Pointe-à-Callière, this building functioned for over 130 years as a place of community life and prayer, the mother house for their widespread missions and the location for their numerous works of charity. Its construction allowed the congregation to greatly expand their charitable works in Canada’s largest metropolis; and,
- with its plain, austere exterior, the elegance and novelty of its chapel, its rational plan, its creative mixture of Neoclassical and Romanesque Revival styles, and its location on a very large city property, this mother house eloquently embodies convent architecture of the second half of the 19th century, of which it is considered to be an excellent example.

The Mother House of the Grey Nuns was begun in 1869 and was used for over 130 years as the centre of the order’s extensive charity work. The building’s heritage value lies in its role as the home of the order and as the facilitator of their work over the years through functional spaces like a hospital and an orphanage. Heritage value is also derived from the building’s architecture – a mix of the Neoclassical and Romanesque Revival styles that combine to make it an excellent example of 19th century convent architecture. These styles are represented through design elements like the austere stone exterior and the elegant chapel.
