Our contribution is in line with TD’s long-standing commitment to supporting the environment: The building was designed to warrant a silver certificate for Leadership in Energy and Environmental Design (LEED), and the K-Rock Centre will feature a TD-sponsored information kiosk in the main entrance to educate visitors on its innovative structure and environmental benefits. $ The Northern Ecosystem area at Science North is set to undergo significant improvements thanks to a $250,000 investment from TD announced in 2008.
