Tier 2 & Development Charge Refund: Application and Enrollment

Applicants who choose to meet Tier 2, a voluntary higher level of environmental performance may be eligible for a Development Charge Refund.

Certified Tier 2 projects are acknowledged by a brushed steel plaque that is displayed in the building lobby or in another prominent location. The green features of the project are also profiled on the City of Toronto's website. Contact sustainablecity@toronto.ca about profiling your certified Tier 2 project or ordering a sign.

Toronto: LEED Supplement

Achieving the TGS contributes towards LEED certification. The Toronto LEED Supplement summarizes the similarities and differences between the Toronto Green Standard and LEED Canada NC 2009 rating system and notes documentation accepted by the City of Toronto.

What's New with the Toronto Green Standard?

Work on the next version of the TGS (Version 3.0, 2018) is underway with a focus on making greater improvements to environmental, energy performance and resilience in new construction. A report on TGS v3 will go forward to City Council in the fall of 2017.

As part of the TGS update and review, the City Planning Division in partnership with The Atmospheric Fund has undertaken a two-part study on global best practices in energy codes and standards and modelling for energy and GHG reduction targets to a 2030 zero emissions date. The consulting team included Integral Group, Morrison Hershfield and Provident Energy Management. The lead consultant Integral Group worked closely with the City's expert advisory committee to develop robust and defensible targets and costing for five of the most commonly constructed building archetypes in Toronto. Together Tier 1 through 4 provides Toronto's proposed pathway to zero emissions buildings.

Other Resources

The following resources were developed as background to TGS version 2.0 adopted by Toronto City Council in July, 2013:

Go to the City Council adopted report recommendations on version 2.0 of the Toronto Green Standard.

See The Toronto Green Standard Energy Efficiency workshop report which includes case studies of local development projects that have achieved higher levels of energy performance (15% better than current Ontario Building Code) and Tier 2 (25% better than current Ontario Building Code).


Sustainable Buildings Canada prepared two background studies for Version 2.0 TGS with recommended increases in energy efficiency targets for the Toronto Green Standard.

Report #1 Review of Energy Codes and Standards

Report #2 Cost Benefit Study of Building Archetypes

View the tutorial presentation on the Ontario Building Code and TGS energy efficiency requirements prepared by ECOVERT Sustainability Consultants. The presentation introduces and compares requirements and provides additional advice and resources to consider in designing high performance buildings.
