Copeland Transformer Station
Critical to powering the ever-expanding energy needs of the GTA, Copeland Transformer Station is nestled underneath heritage train superstructure John Street Roundhouse in the busiest area of downtown Toronto.

A critical new substation powering Canada’s largest city
On an adjacent site and partially below grade, IBI Group provided planning, architectural and engineering design services for a 230kV substation. As all the transformer stations in the downtown core have met capacity, Copeland Transformer Station is critical to helping Toronto Hydro meet the electrical demand and anticipated growth of the downtown Toronto area. The facility is the first to use gas-insulated transformers (non-flammable, non-toxic, desirable for densely populated areas) in Canada and the second to be built underground.
Spread out over three floors, Copeland Transformer Station includes a 10,000-sq. ft. protection and control centre, two means of vehicle access and all associated amenities. IBI designed the substation to allow for future flexibility and the capacity to accommodate expansion including additional transformers, switchgears and equipment.
Part of the Roundhouse’s original machine shop was removed to accommodate the transformer station, which was then re-assembled in its original state, along with a new park and urban space. The above grade portion of the Copeland is clad with a Corten screen recalling the history of the Toronto Railway Lands and integrating the facility into the surrounding entertainment district.
