Environmental performance

Learn about our environmental commitment and initiatives.

Environmental performance is a core value at Toronto Hydro. As Toronto's electricity distribution company, we actively contribute to the City of Toronto's climate change goals, have a strong record on environmental performance, and have been recognized as a top environmental performer, partner and leader.

Our environmental commitment

On September 30, 2021, Toronto Hydro filed a Climate Action Plan with the City of Toronto, outlining how we can help support a net-zero future for Toronto.

As part of our commitment to meeting the environmental objectives set out in our Shareholder Direction, Toronto Hydro strives to operate in an environmentally responsible manner while supporting the City’s energy, climate change and urban forestry policies, and using emerging green technologies where appropriate.

  • We’ve been recognized as a Sustainable Electricity Leader™ by Electricity Canada in recognition of our commitment to responsible environmental, social and economic practices, and to the principles of sustainable development
  • We operate an Environment, Health and Safety (EHS) Management System in accordance with stringent, internationally recognized standards
  • We continuously monitor and assess all aspects of our environmental performance in an effort to reduce our environmental footprint and improve efficiency
  • We also continue to help our customers be part of the shift to a sustainable economy by connecting renewable power and energy storage to the grid, encouraging the use of electrified transportation and offering online billing to reduce paper consumption

Our environmental initiatives

  • By 2024, we expect to have invested over $9 billion over the prior two decades to renew and expand the electricity distribution system that delivers 93% emissions-free electricity to homes and businesses across Toronto
  • We’re modernizing our grid to make it more resilient to climate change and better able to handle higher volumes of renewable energy projects

Electric vehicle (EV) charging station pilot

We’ve partnered with the City of Toronto to install EV charging stations across the city. This pilot project aims to better understand charging usage in Toronto, help permit holders gain access to on-street charging, and support the reduction of greenhouse gas (GHG) emissions and other emissions harmful to air quality.

Supporting eBus electrification

We’re partnering with the Toronto Transit Commission (TTC) and Ontario Power Generation (OPG) to help implement the TTC’s Green Fleet Program and reduce GHG emissions in the city.

  • We worked with the City of Toronto to help launch its combined solar and energy storage project at a Toronto Paramedic Services station. This project stores clean electricity used to help power the station during outages and reduce greenhouse gas (GHG) emissions
  • We’re also working with the City on a combined solar and energy storage project at the Waterfront Neighbourhood Centre. The system will eliminate the need for fossil fuel-powered generators as backup power at the community centre, along with the associated GHG emissions
  • We're working on an innovative battery energy storage system that will provide Metrolinx with clean and reliable backup power for the Eglinton Crosstown light rail transit (LRT) line. This project eliminates the need for fossil fuel-powered generators as backup power for the Crosstown LRT, along with the associated GHG emissions
  • We recently installed a battery energy storage system at Bulwer Municipal Station, a decommissioned substation in downtown Toronto. This innovative energy solution is expected to help offset energy demands, improve reliability in the area and increase the lifespan of our existing infrastructure

  • We’ve made the largest investment in conservation in the province, helping customers manage and reduce energy consumption
  • Our conservation efforts over the past decade have produced enough cumulative energy savings to power the equivalent of more than 200,000 homes for an entire year

  • We continue to integrate climate change considerations into our operations, including by factoring climate risk into our system and project planning
  • We continue to be an industry leader discussing the impact of climate change on the electricity industry. We’ve contributed to the Canadian Electricity Association’s Climate Change Adaptation Working Group and the Energy Working Group of Canada’s Climate Change Adaptation Platform (organized by Natural Resources Canada), as well as the Canadian Standard Association’s efforts to develop climate change adaptation solutions within the framework of the Canadian Electrical Code
  • We contributed to the City of Toronto's Resilience Strategy through our participation in the Urban Flooding Working Group, which developed a number of recommendations, including the development of city-wide modelling to identify flooding hazards, assess impacts and map vulnerabilities (which would help us to more effectively mitigate the impacts of flooding, such as potential power outages)
  • In addition to increasing the physical resiliency of the grid to the impacts of extreme weather events, we continue to develop our disaster preparedness management program to help improve our response to these types of events and emergencies, such as wind and ice storms
