Filing Requirements for Electricity Transmission Projects under Section 92 of the Ontario Energy Board Act

The Ontario Energy Board (OEB) granted approval of the Power West Toronto project in late April 2017. This report will provide you with insight into how the OEB determines whether an electricity project is in the public interest.

Project Overview and Construction Notice to the Community

Hydro One first notified local residents and businesses about the Power West Toronto Project (West Toronto Transmission Line Refurbishment from Manby to Wiltshire Transformer Stations) in October 2016.

Runnymede Transformer Station - Public Information Session (May 30, 2017)

The intent of the public information session was to hear from residents, answer questions and provide information about the Power West Toronto project and describe the work being done at the Runnymede Transformer Station in detail.

Montgomery Road Area Updates – Community Drop In Session (July 11, 2017)

As part of the project, Hydro One will be working on the transmission line beside the Memorial Pool and Health Club and adjacent to Westrose Avenue this summer. To provide more information about the work involved, Hydro One will be hosting a community drop-in style meeting on July 11 at Our Lady of Sorrows Separate School.

Electric & Magnetic Fields (EMF) Information

Electric and magnetic fields (EMFs) are invisible forces that surround electrical equipment, power cords, and wires that carry electricity. EMFs are strongest when close to their source. As you move away from the source, the strength of the fields fades rapidly. Hydro One retained Kinetrics to conduct an Electric and Magnetic Fields study at Woolner Park, and a copy of the draft report is available for viewing.

Health agencies and a large number of reputable scientific organizations around the world have concluded that the scientific research does not demonstrate that EMFs cause or contribute to adverse health effects.

Frequently Asked Questions

Hydro One, together with Toronto Hydro, is making major infrastructure upgrades in the city’s west end to help power growth in Toronto. This work began June 2017 and will go through to December 2018.

The project involves installing new equipment, including two new transformers to Hydro One’s existing Runnymede Transformer Station located at 99 Woolner Avenue, which will require expanding the current station footprint. This is part of a larger effort which also includes upgrading 10 km of the existing overhead transmission line extending from the station.

While this work is focused in the west end, it will help strengthen Toronto’s electricity grid, by providing power to meet the anticipated economic and population growth, and is required to power the Eglinton Crosstown LRT.

Power West Toronto is funded by Toronto Hydro and the work is being executed by Hydro One. Both Toronto Hydro and Hydro One have been in close contact with key stakeholders and community leaders regarding this project.

Hydro One builds, owns, operates and maintains the electricity transmission system across Ontario. High voltage power is converted to lower voltage and distributed by Toronto Hydro to homes and businesses.

Toronto’s electricity needs have changed dramatically since the equipment was last upgraded in the 1960s. These upgrades are critical to provide power capacity for area growth, better reliability and resiliency against outages. In addition, the Eglinton Crosstown LRT needs an available power supply by January 2019.

The Eglinton Crosstown LRT needs an available power supply by January 2019, so Hydro One’s work must be completed in time. Additional capacity is required now to be able to meet the forecast load demand.

Power West Toronto will directly benefit thousands of residents and businesses in Toronto by upgrading the infrastructure to increase power capacity and ensure better reliability and resiliency against outages, and is required to electrify the Eglinton Crosstown LRT.

As the power grid in Toronto is interconnected, the work being done in the west will also help electricity flow to other areas of the city.

No. The system is built with the ability to re-route power from other areas to ensure that users don’t experience outages during construction.

Construction will be centred on the Runnymede Transformer Station near Jane Street and St. Clair Avenue West, as well as along the 10 km hydro corridor running from Kipling Avenue through to Wiltshire Avenue near Davenport Road.

For more information on potential impact to communities near the construction zone, please see the neighbourhood maps.

People living in the area can anticipate restricted access to some pedestrian and recreational spaces along the transmission corridor where construction will take place.

We understand that construction work can be disruptive, so to minimize impact, Hydro One and Toronto Hydro are working closely with the community to provide regular and timely updates on planned work.

Our goal is to anticipate the needs of residents and businesses, and identify opportunities to mitigate disruption we may cause in the construction areas, while executing the required work safely and responsibly.

Hydro One and Toronto Hydro are committed to communicating early and often with the local community, residents and all those affected by this project. We’ll be providing information through this website, as well as through our social media sites, printed materials, advertisements in Metroland newspapers, and through public information centres.

 As part of the Power West Toronto project, Hydro One will be making upgrades to transmission towers located in the Kipling and Islington TTC parking lots. Construction will start on September 24, and will require about a third of the spaces in these parking lots to be closed. We are operating on a very aggressive construction timeline to ensure the least possible disruption.

We encourage people to take this work into account when planning their trips with the TTC.

Construction will start on September 24, and will require about a third of the spaces in the parking lots at both stations to be closed. Typically, a project of this nature could take several months; however, Hydro One will be using every available crew to complete the project as safely and quickly as possible.

We know construction work can be disruptive, and we are committed to communicating all aspects of this project early and often.

Below is a list of activities we are undertaking to communicate with commuters:

  • Flyers will be distributed to cars parked in the lots
  • Signage will be placed at TTC stations and in parking lots
  • We will run ads in local newspapers
  • A press release will be issued to Toronto media so they can help communicate the project
  • Regular updates will be made on social media and on the project website, PowerWestToronto.ca

We will continue to keep commuters updated on the timeline and scope of the project, using all channels available to us.

We are operating on a very aggressive timeline to finish as quickly as possible, while still ensuring work progresses safely and responsibly. Typically, a project of this nature could take several months; however, Hydro One will be using every available crew to complete the project in approximately four to six weeks. Our crews will also be working longer hours – from dawn until dusk – while still abiding by regulations set by the Ministry of Labour.

Our construction will require us to close about one third of the parking spaces at these stations. For the rest of the lots, there will be limited free parking available at both stations during construction. We encourage commuters to consider alternatives to parking at the station, such getting to the station on foot, bike or bus, or considering carpooling.
