The Bruce to Milton transmission line is one of several projects that Hydro One is undertaking to meet Ontario’s needs for the 21st century. As our population and economy continue to grow, we need to ensure we have the power to light our homes and businesses in the future. The Bruce to Milton Project supports the Province’s climate change and clean air initiatives by providing transmission capability to reliably and safely deliver an additional 3,000 megawatts (MW) of energy from clean and renewable sources – enough power for Milton, London, Guelph, Chatham, Mississauga, Brampton, Hamilton and St. Catharines, combined.

Join the Bruce to Milton Mailing ListThe Ontario Power Authority (OPA) has recommended Hydro One begin the approvals process required to build the new transmission line that would deliver power from clean renewable and nuclear sources in the Bruce area to Ontario’s electricity consumers. To provide the necessary transmission capability, Hydro One is proposing to build a new 180 kilometre double-circuit 500,000 volt (500 kV) transmission line from the Bruce Power facility in Kincardine to Hydro One’s Milton Switching Station in the Town of Milton. The earliest in-service date for the new line is the end of 2011. Read the OPA's letter to Hydro One (PDF 1.8 MB) or visit their project web page.

Download the Project Newsletter (PDF 2.9 MB)Before this project can be built, a number of approvals are required, including Ontario Energy Board (OEB) and Environmental Assessment (EA) approvals. This is an exciting time in the development of Ontario’s transmission infrastructure. As we move forward on the clean energy corridor, Hydro One is committed to working with residents, businesses, Aboriginal groups and the communities we serve in an open, fair and transparent manner, providing consultation opportunities throughout the process to ensure we continue to deliver reliable and affordable electricity across Ontario.

Watch a fly-over video of sections of the proposed line:

Ontario Power Authority
The Ontario Power Authority (OPA) was established by the Government of Ontario in 2004. Its role is to ensure a long-term supply of electricity for the Province. This includes a variety of responsibilities, including conservation and demand management initiatives, preparing a long-term integrated power system plan (IPSP), and ensuring investments in new electricity resources. www.powerauthority.on.ca
Ontario Energy Board

The Ontario Energy Board (OEB) regulates Ontario’s natural gas and electricity industries. The OEB is responsible for ensuring construction and operation of proposed transmission facilities are in the public interest. In carrying out this mandate, the OEB considers the impacts that the project may have upon consumers with respect to prices, as well as matters that concern the reliability and quality of electricity service. When the OEB receives an application, it reviews the material, makes the information public and provides an opportunity for stakeholder and Aboriginal input. www.oeb.gov.on.ca

Ministry of Environment
The Ministry of the Environment (MOE) works to protect, restore and enhance the natural environment through tough legislation and enforcement, innovative programs and initiatives, strong partnerships, and public engagement. The Ministry works to provide all Ontarians with safe and clean air, land and water. www.ene.gov.on.ca
Hydro One Networks Inc.

Hydro One Networks Inc. is responsible for delivering electricity safely, reliably and responsibly to homes and businesses in the Province. We own and operate Ontario’s 29,000 kilometre high-voltage transmission network, and our job also includes building new transmission facilities. www.hydroonenetworks.com

Along with meeting the technical need to deliver the additional power, making best use of existing infrastructure was a critical factor in the OPA’s determination of the Bruce to Milton route. The use of existing transmission corridors before the development of new ones is consistent with the Province’s land use policy. Read the OPA's letter to Hydro One (PDF 1.8 MB).

The need and rationale for a new transmission line is discussed in more detail in the OPA’s Transmission Discussion Paper #5 and Discussion Paper #7, which can be downloaded from www.powerauthority.on.ca and will be available at Public Information Centres in the weeks to come.



The OPA has also recommended the installation of two near-term measures and two interim measures to ensure reliable power transmission from the Bruce area to points east until the new 500kV line can be placed in-service in late 2011:


Near-term Measures

  1. Increase the capacity of the existing 230kV lines from Hanover to Orangeville by raising the height of the existing wires on some of the existing towers.
  2. Install voltage support facilities at existing Hydro One stations in the western GTA and southwestern Ontario. Additional voltage support facilities beyond these may be required if the 500kV line in-service date is delayed beyond 2011.

Interim Measures

  1. Expand the capability of the existing generation rejection scheme in the Bruce area.
  2. Install series compensation on the existing Bruce to Longwood and Longwood to Nanticoke 500 kV lines. Its use is subject to a delay of in-service of the 500kV line beyond 2011, and technical acceptability that is the subject of a due diligence study to be conducted by the OPA. Hydro One is also assisting the OPA in this study.

The target in-service date for these measures is 2009. The OPA has noted that the interim measures are not alternatives to the new transmission line as a long-term solution since they increase the risk to the security and reliability of the power system. Aside from series compensation which requires EA approval, the other measures do not require EA or OEB approvals.

The Bruce to Milton project requires a widening of the existing corridor by approximately 53m - 61m. The widening will make it necessary for Hydro One to obtain additional land rights, starting with discussions with property owners. In parallel with these discussions, Hydro One will also prepare to expropriate easements, and in a limited number of cases purchase property for the widened corridor to meet the project schedule. Payment for expropriated lands will be based on market value. Hydro One plans to install the new towers in line with the existing ones to minimize visual impacts, subject to any environmental and technical constraints.

We appreciate that acquiring property rights can be inconvenient and disruptive to owners. Hydro One will deal with every affected land owner in a fair, open and consistent manner. In summer 2007, a Hydro One property agent will be contacting directly affected property owners to discuss the land acquisition process and answer questions about the project. In the meantime, you can contact us toll

This project is subject to the requirements of the Environmental Assessment Act (EAA) and an Individual Environmental Assessment will be completed.

There are four key phases of the EA process:

  1. EA Terms of Reference Preparation
  2. EA Terms of Reference Review and Approval
  3. EA Study Preparation
  4. EA Study Review and Approval

A Terms of Reference establishes the framework for the preparation and review of the EA. It outlines how the EA will be conducted and helps ensure that the public, Aboriginal peoples and government agencies know what will be considered. The Terms of Reference is subject to approval by the Minister of the Environment.

We are currently at the beginning of Phase 1 of the EA process: the preparation of the EA Terms of Reference. Public and Aboriginal input will be collected during the development of the Terms of Reference. The MOE will also initiate a formal public and agency comment period on the Terms of Reference once it is submitted.

This EA Study will focus on the transmission route from Bruce to Milton. It will consider design alternatives (e.g., tower types and locations on the corridor and access route locations), measures to avoid and minimize effects and identify advantages, disadvantages, and net effects of the project.

Information specifically related to the EA process may be found on the following pages of the MOE website:

In March 2007, Hydro One filed two applications with the OEB related to the Bruce to Milton Project:

Leave to Construct Approval
The project is also subject to "Leave to Construct" approval under Section 92 of the Ontario Energy Board (OEB) Act. The OEB review of Hydro One's application for leave to construct approval also includes provision for public consultation. Download a copy of the application filed with the OEB on Thursday, March 29, 2007. Read the OEB letter to landowners clarifying their role in the process (sent May 25, 2007).

    Early Access to Land
    Early access would allow Hydro One employees and representatives to access properties along the proposed line to undertake a limited number of activities (including field and legal surveys and soil testing) during 2007. If you are an affected property owner, Hydro One will communicate with you before entering onto your land. Download a copy of the application (filed with the OEB on Friday, March 30, 2007). Read the OEB letter to landowners clarifying their role in the process (sent May 25, 2007).
