Well, it appears it is not quite everything, but most of the structure:

"This report recommends that City Council state its intention to designate the properties at 233-237 College Street and 189 Huron Street under Part IV, Section 29 of the Ontario Heritage Act for their cultural heritage value. Located on the southeast corner of College and Huron Streets, the site contains a commercial block historically known as the John Davison Buildings (1890)."
From the report:
"Staff have completed the attached Heritage Property Research and Evaluation Report (Attachment No. 3) and determined that the properties at 233-237 College Street and 189 Huron Street meet Ontario Regulation 9/06, the criteria prescribed for municipal designation. The property at 183 College Street, built in 1909 for the College Apartments, and the vacant portions of the site at 231 College and 177 Huron
are not identified for designation.
The properties at 233-237 College Street and 189 Huron Street are worthy of designation under Part IV, Section 29 of the Ontario Heritage Act for their cultural heritage value, and meet the criteria for municipal designation prescribed by the Province of Ontario under the categories of design and contextual values. The John Davison Buildings at 233-237 College Street and 189 Huron Street are valued
as highly crafted representative examples of late 19th century commercial structures from the late Victorian era with Italianate styling, which are distinguished by the chamfered or bevelled northwest corner
and the application of elaborate brickwork and fine terra cotta detailing that is increasingly rare on commercial buildings.
Anchoring the southeast corner of College and Huron Streets, the John Davison are historically and visually linked to their surroundings, providing a prominent historical transition from the institutional and
commercial precinct on College Street to the surviving late 19th century residential community southeast of College Street and Spadina Avenue."
