Originally housed the offices of the National Sanatorium Association.

The property at 223 College Street has design value as a commercial building dating to the World War I era and designed in the Edwardian Classical style that was popularized during that era.  The building is particularly distinguished by its classical detailing that incorporates stone surrounds on the north and east entrances, as well as the cartouche (north) and the shield motifs. 
Contextually, the property at 223 College Street is valued for its role in defining, supporting and maintaining the historical character of College Street, east of Spadina Avenue, which evolved from its origins as a residential district to one welcoming institutional and commercial buildings with heights associated with the “tall building” boom in Toronto during the early 20th century.
The building at 223 College Street is historically, visually and physically linked to its corner setting where in its scale and appearance it complements the adjoining commercial building at 229 College Street, which is known historically as Oddfellows Hall (1912), as well as the institutional edifices on the University of Toronto’s St. George Campus, opposite.
