Historic Sites of Manitoba: St. Boniface Sanatorium / St. Vital Sanatorium / St. Amant Centre / St. Amant School (440 River Road, Winnipeg)

Located on lot 55 in St. Vital, the 250-bed, red brick St. Boniface Sanatorium (also known as the St. Vital Tuberculosis Sanatorium) was an unemployment relief project designed by Winnipeg architect John Nelson Semmens and built in 1930-1931 by a group of local contractors and suppliers, including contractor Joseph Albert Tremblay, John Fabris & Sons (tile and marble), Cowin & Company (steelwork, structural engineers), Kelvinator Company (electric refrigeration), J. H. Ashdown Company Limited (interior hardware), Cusson Lumber Company and Brown & Rutherford Company Limited (lumber), T. Eaton Company Limited (furnishings), Carter-Halls-Aldinger Company (construction, Children’s Pavilion), and many others.

The campus consisted of three structures made of brick, concrete, and Tyndall stone. The four-storey main building was laid out in an “H” pattern with ground-level space in both the south and west wings allotted to patients, thereby affording them the most access to sunlight. Staff and service rooms occupied the northern side of the structure. The first floor central area contained administration quarters and a chapel. On the second and third floors were diagnostic equipment and examination rooms, with the fourth floor containing an auditorium and accommodation for sun treatment sessions. This structure was connected via tunnels to the two-storey Children’s Pavilion (containing 50 of the 250-bed total), and a service building that housed laundry services, the powerhouse, and male staff quarters. The Sanatorium was operated under the auspices of the Grey Nuns of St. Boniface, known formally by their incorporated name of “Les Soeurs de la Charite” (Sisters of Charity).

The project cost some $800,000 to complete and was officially opened on 30 September 1931. An inaugural mass in the chapel kicked-off the day’s events, the sanctuary seating some 200 attendees. That was followed by speeches from Premier John Bracken, Archbishop A. A. Sinnott, and Health Minister E. W. Montgomery to an invitation-only crowd of 400 people. An open viewing was held that afternoon for the general public.

Renamed the St. Vital Hospital, it was later closed and threatened with demolition. Instead, it was reopened on 2 June 1974 as a facility for the care of mentally handicapped people known as the St. Amant Centre, named for Beatrice St. Amant. A school was operated at the site, for which the St. Vital School Division took over responsibility for programming and educational services on 1 January 1975, first on a trial basis, then permanently.
