The John C. & Sally Horsfall Eaton Ambulatory Care Centre at St. John’s Rehab Hospital

By Terry Montgomery and Tye Farrow

This project consists of a two-storey, 4700m2 addition to an existing rehab hospital on a treed 9.5 hectare site in North Toronto. The hospital was originally owned and run by the Sisters of St. John the Divine who purchased the property in the 1930s so that the hospital could enjoy the benefits of the rural surroundings outside of the city centre. Since that time, the city has grown up around the hospital, but the large park-like site has been largely preserved.

Pei's 1973 Herbert F. Johnson Museum of Art or the conceptual provocations of OMA's new building for the architecture school, the recently completed visitors' center at the gardens is a quiet, nearly invisible presence in the landscape.
