205 Yonge Street, Neoclassical bank building in downtown Toronto, Canada.

205 Yonge Street is a four-story neoclassical building designed by E. J. Lennox, with a domed roof and Corinthian columns on its front facade. It was built in 1905 for the Bank of Toronto and offers 17,423 square feet of space. The building stands on the east side of Yonge Street, across from the Toronto Eaton Centre and just north of the Elgin and Winter Garden Theatres.

E.J. Lennox designed this four-story building for the Bank of Toronto, and it was completed in 1905. The Ontario Heritage Act protected it in 1975. The Toronto Historical Board occupied it until 1998, when the agency became Heritage Toronto and moved out. The building was closed to the public and being refurbished when it was put up for sale in April 2019.

The building housed the Toronto Historical Board, the city agency responsible for protecting historic sites, until it left in 1998 when the agency became Heritage Toronto. Heritage Toronto's logo is based on the profile of 205 Yonge Street, so the building's outline now stands for heritage conservation in the city.

The building sits directly across from Toronto Eaton Centre, making it easy to spot while walking along Yonge Street. You can view and photograph it from the street, though note that it is protected heritage property and viewing is from the exterior.

The silhouette of this building became the visual profile for Heritage Toronto's organizational logo, turning it into a symbol of architectural preservation in the city. This choice reflects how deeply the structure's distinctive shape speaks to the heritage conservation movement.
