Sustainable Technologies

Sustainable Technologies Evaluation Program logoThe Sustainable Technologies Evaluation Program (STEP) is a multi-agency program, led by the TRCA. The program was developed to provide the data and analytical tools needed to support broader implementation of sustainable technologies and practices within a Canadian context.

The main program objectives are to:

  • monitor and evaluate clean water and energy technologies
  • assess barriers and opportunities to implementing technologies
  • develop tools, guidelines and policies, and
  • promote broader use of effective technologies through research, education and advocacy

Key Focus Areas

Activities conducted through STEP are centered around five key theme areas. These include urban runoff management and green infrastructure, construction site erosion and sediment control, preserving and restoring healthy soils, natural features and systems, and green energy.

Training and Events

STEP offers training and workshops for homeowners and professionals on a broad range of sustainability topics. These cover renewable energy technologies, green infrastructure, green building and more. Visit our Training and Events page to learn more.

Living City Laboratories

To help facilitate collaborative monitoring and research on topics of interest, STEP operates and maintains several field laboratories with state-of-the-art monitoring instruments and data acquisition systems. The laboratories act as real world demonstrations for visitors and provide the controlled conditions needed to monitor and evaluate technologies and systems. To learn more about our field laboratories and opportunities for research collaboration, visit our About Us page.

Resource Library

STEP is developing a green infrastructure resource library that will act as the Conservation Ontario hub for local research, monitoring data, guidelines, decision support tools, case studies, and more. Though still in the early development phase, there are currently nearly 100 documents available for download.

Technology Verification

STEP is responsible for independent, third party testing and verifcation of stormwater management and renewable energy technologies as a member of the Globe Performance Solutions Consortium (GPS). GPS is the delivery agent for the Canadian Environmental Technology Verification Program.

Working with STEP

Over the last 10 years, STEP staff has worked with over 100 partners from the private, public and non-governmental sectors. We continue to seek opportunities for collaboration that help further our mandate to foster broader uptake of innovative environmental technologies and practices.
