Preserving the environment is an important part of our business. At Toronto Hydro, informing our customers about conservation programs, supporting the city's urban tree canopy, and doing our part to reduce the risk of environmental spills and other impacts of our business, is all in a day's work.  


Conservation and Demand Management

  • Goal: Achieve 1,304 GWh of energy savings and 286 MW of summer peak demand savings between January 1, 2011 and December 31, 2014
  • Progress: To date, we have achieved an estimated energy savings of 1,034 GWh and total demand reduction of 103 MW*.

City-owned buildings get an injection of solar power

In 2012, the City of Toronto and Toronto Hydro launched the first phase of a joint Solar Photovoltaic
(PV) Project. The electricity is purchased under the terms of Feed-in Tariff (FIT) contracts with the
OPA , and at least 60 per cent of the PV equipment will be made in Ontario, which will help support
the growth of the solar energy industry locally.

Greenhouse Gas (GHG) Emissions

We measure our greenhouse gas (GHG) emissions from four key sources: our fleet, our facilities, line losses and Sulfur Hexafluoride (SF6) gas in equipment. Since 2007, we have reduced our total
emissions by 30 per cent. I

In 2012, we generated 110,300 tonnes of carbon dioxide equivalent (tCO2e); year-over-year
variances include:

Waste Streams

In 2012, we sent approximately 57 metric tonnes of non-hazardous materials to landfill. We have set a target to reduce our non-hazardous waste by 10 per cent in 2012.


Toronto Hydro’s hazardous liquid waste includes petroleum distillates, industrial waste, oil skimmings,
sludges, Polychlorinated biphenyl (PCBs) and lubricants. Liquid waste accounts for approximately
95 per cent of our total hazardous wastes.

Waste Recovery

Toronto Hydro continued on with our investment recovery program to reduce the amount of non-hazardous material sent to landfill. In 2012, we recovered more than 2,138 metric tonnes of materials and earned approximately $3.1 million by selling these scrap materials back to the marketplace.

Biodiversity — Protecting Toronto’s Urban Forest and
Service Reliability

We do our best to preserve the City’s urban forest while protecting service reliability for our
customers. We have implemented a cycle pruning program and trees are typically trimmed once
every three years. Our forestry representatives collaborate with our designers and construction
crews to develop projects that minimize our impact to neighbourhood trees. While installing new
underground infrastructure, we protect roots from damage through vacuum excavation, root
pruning and deep root fertilization, and direction boring.

Achieving ISO 14001 Certification

In 2012, one of our goals was to achieve certification of our integrated Environment, Health and Safety Management system to the international standard ISO 14001. Through tremendous efforts and commitment by staff at all levels, supported by an organization-wide engagement and communication plan, we successfully completed the required audits and received confirmation of certification in early 2013.

Planting New Roots

Our annual tree planting event continued at Centennial Park in Etobicoke. We planted 200 trees and shrubs with the help of more than 150 employees accompanied by 25 volunteers from LEAF — Local Enhancement and Appreciation of Forests and the City of Toronto. Since 2004, Toronto Hydro employees have planted 2,755 trees in various parks across the City.


On May 6, 2012, Toronto Hydro
employees, Local Enhancement &
Appreciation of Forests (LEAF) and the City of Toronto planted over 200 trees and shrubs at Centennial Park in Toronto.
