The Toronto Green Standard (TGS) is a two-tier set of performance measures for sustainable site and building design. Tier 1 is required for new construction in Toronto and Tier 2 is a higher, voluntary level of performance with a financial incentive. Projects that achieve Tier 2 may be eligible for a partial refund on Development Charges paid to the City.
The TGS is complements working with the LEED (Leadership in Energy and Environmental Design) voluntary rating system. Achieving Tier 1 and Tier 2 performance measures will contribute towards LEED credits. See the Toronto LEED Supplement for a comparison.
Greening new development helps to reduce future infrastructure demands and environmental impacts making a healthier, more livable city. The TGS integrates environmental performance requirements to improve our air and water quality, reduce green house gas emissions, enhance urban ecology and reduce solid waste to landfill.
