Supply to York Region - Transmission Line Project

What's New

  • March 8, 2005 - Hydro One withdraws draft Environmental Study Report
    Hydro One has advised the Minister of the Environment that it is withdrawing its draft Environmental Study Report (ESR) for the Supply to York Region Transmission Line Project. Hydro One made this decision in light of the reviews currently being undertaken by the Ontario Energy Board and Ontario Power Authority (OPA) to assess local electricity reliability issues in Ontario, including those in York Region, and identify possible solutions. Hydro One fully supports the OPA's mandate to examine a comprehensive range of electricity reliability and supply options, and will provide its full cooperation and support to assist the OPA in arriving at solutions to meet the province's electricity needs.

Background

York Region is one of the fastest growing areas in Ontario and includes the communities of Markham, Richmond Hill, Vaughan, Aurora, Newmarket, King Township, Whitchurch-Stouffville, East Gwillimbury and Georgina. Hydro One, working together with local utilities, has assessed a variety of transmission options to keep up with the growth and satisfy the supply needs of York Region. The utilities and Hydro One agree that, regardless of the selected option, by 2006 additional supply will be required.

Based on an assessment of the options, two transmission route alternatives were presented at Public Information Centres held in April/May 2004, both making use of existing transmission corridors. See map (PDF 2.5 MB)

1) Upgrade the existing transmission line from Parkway Transformer Station (TS) to Armitage TS
2) Upgrade the existing transmission line from Claireville TS to Armitage TS

These alternatives are expected to have the least impact on the environment and local community. Hydro One continues to consult with stakeholders on these and other options to meet the need for electrical supply in York Region.

All of the options identified to date are subject to Environmental Assessment (PDF 2.2 MB) and Ontario Energy Board review and approval. These processes provide additional opportunities for input from the local community and other stakeholders.

Supply to York Region - Transmission Line Project

March-May 2004
Initiate consultation process
  

Utilities
Hydro One has been working with local utilities to ensure that together, we can accomodate growth in the region and continue to supply reliable electricity to the York Region communities. The results of this cooperation are available in this joint planning study (PDF 1.1 MB).

Local Elected Officials and Staff
Hydro One has been meeting with staff at Municipal and Regional levels to discuss this project. We have also made presentations to Municipal Councils on request. Here is an example of information presented at council meetings (PDF 538 KB).

Public Information Centres
Hydro One has held public information centres throughout the York Region. Through a series of session panels (PDF 1 MB), brochures (PDF 657 KB) and discussions we discussed the need for the project, two of the options being considered and the process. From these sessions the public was able to give us valuable feedback.

May 2004
Initiate meetings with interested stakeholders to address concerns
   As a result of the initial public information sessions, meetings with stakeholder groups who have had questions or concerns about the project (such as the York Catholic District School Board) are being held. To allow for feedback from all interested parties or groups we have deferred the date for selection of a preferred route from that of the schedule presented at the initial public information centres.

Summer/Fall 2004
Continue to work with stakeholders.
Conduct additional Public Information Centres
   Since April 2004, a series of Public Information Centers and several stakeholder consultation meetings have been held. During these information exchanges, we received a significant amount of input. Your issues and concerns are important to us and we will consider them closely while evaluating route alternatives.

Over the summer we will continue discussions with interested groups. We have also been attending public sessions to ensure that all interested parties are informed and have the opportunity to understand and comment on the alternatives for the future supply to York Region. A sample of the information presented at these public meetings can be reviewed below.

Electric and Magnetic Fields (EMF) Workshop - June 16, 2004:

A panel of experts included; Dr. Jack Sahl (PDF 11 KB), Director of Environment & Safety, Southern California Edison, Dr. Mark Greenberg (PDF 12 KB) Medical Director, Pediatric Oncology Group of Ontario, and Dr. Magda Havas (PDF 8 KB), Associate Professor of Environmental and Resource Studies, Trent University, who was invited by local interest group Stop Transmission lines Over People (STOP). The panel presented views from a public health, medical and biological/environmental perspective on the potential risks to human health. Municipal and regional planning staff and elected officials, local MPPs, the Ministry of Energy, York Region electric utilities, Regional Health Services staff, representatives of local ratepayer groups, and members of STOP's Executive Committee were invited and over 50 people attended.
