25 St. Clair East Rehabilitation Project
From: Public Services and Procurement Canada
25/55 St. Clair Avenue East in mid-town Toronto is undergoing a major rehabilitation which will reduce the building’s greenhouse gas emissions by over 80% and serve as a flagship model of the Government’s commitment to reducing its carbon footprint. The project will demonstrate the government’s commitment to the environment, incorporating elements such as a high-efficiency building envelope, a geothermal system, and photovoltaic panels.

The 25 St. Clair East Rehabilitation project will demonstrate the government’s commitment to the environment; incorporating elements such as high-efficiency building systems, geothermal system, and photovoltaic panels. These elements are anticipated to reduce the building’s greenhouse gas emissions by over 80%. Once renovated, the building will accommodate several government departments and agencies, including Canada Revenue Agency (CRA), Canada Border Services Agency (CBSA), Immigration and Refugee Board (IRB) and other federal occupancies. Upon completion, the facility will serve as the flagship Government of Canada Building (GOCB) in the Ontario Region. The project is a critical element in the overall strategy to include a rationalization and reduction of overall space holdings in downtown Toronto. The project will be implemented by applying the Government of Canada Workplace (GCWorkplace) standard, which will result in an estimated overall space savings of approximately 9,000 m2.

- a CO2 cloud with an arrow pointing down appears above representing carbon dioxide hitting the building
- numbers 1 through 12 superimposed on building’s key environmental features
Text describing the 12 environmental features identified on the cross section image of the building:
- Greenhouse gas emissions (GHG): The building is designed to reduce GHG emission by almost 80% and save over 700 tonnes/year
- Solar electricity: 850 photovoltaic panels generate 348 MWh/y of renewable power which is approximately 15% of totally energy use and approximately reduces GHG emissions by 65 tonnes
- Building reuse: Maintain existing building structure (floors, roof, columns) will reduce landfill and energy use
- Reduced lighting: Occupancy sensors switch off or dim lights, reducing lighting energy
- Health & wellness: Open and accessible interiors stairs encourage occupants to use stairs instead of elevators
- Bird friendly glazing: Glazing located within first 12 metres of the building above grade will have distinctive pattern to reduce bird collisions and mortality
- Bicycle storage: Interior bicycle storage spaces and shower/locker in secure facilities encourage bicycle usage
- Water harvesting: Basement cistern will gather rain water from the roof for reuse in the building’s mechanical systems
- Geo exchange system: 58 ground source boreholes will be drilled 150 metres under the existing building garage to offset heating and cooling loads
- Smart building control and metering: Digital controls throughout allow for better control of building systems and lighting for increased occupant comfort and reduced energy use
- Transportation/commuting connection: Connections to Toronto Transit Commission subway and streetcar provide public transportation connections for staff and users
- Electrical vehicle charging: Electrical vehicle charging stations (EVCS) will be provided and rough-ins for 40 more EVCS
In Pursuit of Carbon Neutral: 25 St. Clair East Building
- Tenants vacate building in July 2018
- Construction begins in Sept 2018
- Phase 1: Completion of base building – spring 2023
- Tenants begin move in summer 2023
- Phase 2: Completion of fit-up – summer 2023
- Remaining tenants move in fall 2023
Benefits to Canadians
This rehabilitation project will create more than 300 full time construction and consultancy jobs for four years while it is underway. Additionally, once the project is completed, approximately 1500 federal employees will work in the building and will contribute to the local economy when visiting shops and restaurants in the area.
The significant sustainability elements of this project will contribute to meeting Canada’s commitments in reducing greenhouse gas (GHG) emissions.
Throughout the life of this project, and upon completion of the renovations, 25 St. Clair East will be a part of the Canadian National Institute for the Blind’s (CNIB) “Shop Talk: BlindSquare Enabled” program which allows visually impaired individuals the opportunity to independently navigate within a neighbourhood with the use of Bluetooth-enabled personal devices.
