The Elementary Teacher’s Federation (ETFO) represents over 78,000 teachers in Ontario’s public elementary schools. The new headquarters are designed to provide a high quality work environment. It is one of the most energy-efficient buildings in Toronto and was the first office building to receive the LEED Platinum Certificate. The building demonstrates to students, pupils, citizens, and developers that architecture can actively contribute to positive change and sustainable urban development. Photos: Ditz Fejer
