Developing Toronto

Toronto Green Standard

The Toronto Green Standard (TGS) is a two-tier set of performance measures with supporting guidelines related to sustainable site and building design for new private and public development.

The standards are designed to work with the regular development approvals and inspections process. New planning applications are required to document compliance with Tier 1 environmental performance measures. The TGS has been in place since January 31, 2010.

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

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.

Highlights of Changes to the TGS

See the presentation on the Toronto Green Standard 2014 Review and Update Highlights.

Raising the Bar on Energy Efficiency

The 2014 Toronto Green Standard (Version 2.0) includes new and improved performance measures and higher energy targets of 15% above the Ontario Building Code (Tier 1) and 25% above the Ontario Building Code (Tier 2). The TGS is a key strategy for reducing green house gas emissions by 30% by 2020 and 80% by 2050. According to the Toronto Atmospheric Fund (TAF), Toronto's improved energy efficiency standards will save Toronto's citizens and businesses an estimated $114M by 2025 and avoid over 750,000 tonnes of climate-damaging GHG emissions by 2025 at marginal incremental design and construction costs.

Drought Tolerant Landscaping: A Resource for Development

This document is a handy reference for professionals working in the development industry to find drought tolerant planting material (pdf) because reducing the demand for potable water in landscaping and bringing ecological diversity to the landscape is a Tier 1 requirement of the TGS. 

Green Buildings Guide

Toronto Green Buildings Guide in the Fall 2011 issue of Canada Green Building Council Toronto FOCUS magazine was prepared for the Green Build conference held in Toronto in October 2011. It's a handy source for information on; City green programs and policies, innovative Toronto companies and Toronto-area projects.
