From the City's report regarding the inclusion of these addresses on the Heritage Registry:
"With their individual design features, the properties at 201 and 203 Gerrard Street East have cultural heritage value as fine representative examples of late 19th century semi-detached houses in the popular Toronto Bay-n-Gable style, which are elevated by the unique treatment of each unit with different types of bay windows and the placement of the main entrance to each house on different elevations. The Cecilia Lloyd/Harry Rosser Houses are further distinguished by the terra cotta detailing and decorative brickwork associated with late Victorian architecture.

The Cecilia Lloyd/Harry Rosser are valued for their historical associations with the area adjoining Allan Gardens as it developed in the late 19th century as an upscale residential neighbourhood in Toronto. With their proximity to Sherbourne Street, the houses at 201 and 203 Gerrard Street East are typical of the substantial residential buildings that marked the corridors of Church, Jarvis and Sherbourne streets and housed Toronto’s community leaders.

Contextually with their proximity to Allan Gardens, the properties at 201 and 203 Gerrard Street East contribute to the character of the neighbourhood as it developed in the late 19th century as the setting of high-end residential buildings. The Cecilia Lloyd/Harry Rosser Houses are also historically, visually and physically related to their surroundings as part of a residential enclave along Gerrard and Sherbourne Streets where many of the surviving period buildings are recognized on the City of Toronto’s Heritage Register."
