Environmental Assessments

As we work toward economic recovery throughout the Greater Toronto and Hamilton Area, Metrolinx is continuing to advance projects to support the long-term growth of the GO rail network.

Throughout the pandemic, transit construction projects have been considered an essential service by the province; therefore, construction has moved forward on all projects. We are very aware that the new normal post-COVID may look very different for transit and we have begun looking very closely at all of our policies and procedures to ensure we adapt appropriately. As we move forward, we know that building complete communities with good access to transit will continue to be important. At this point, Metrolinx and Infrastructure Ontario are closely monitoring the market to understand the impacts of the pandemic.

Metrolinx continues to grow, expand and to adapt transit service to the needs and demands of our ever-changing region. We look for ways to evolve our service that will meet passenger’s commuting needs, while also providing solutions to address traffic congestion.

A first step in any project is comprehensive planning. During this planning process, many of Metrolinx’s expansion projects must undergo a Transit Project Assessment Process (TPAP) or focused impact assessment process. This process is required to assess projects that may have potential impacts during construction and/or operation and may need measures to mitigate these impacts. The TPAP is regulated by the Ministry of Environment, Conservation and Parks (MECP), and includes a stakeholder consultation and review process before proceeding to the next phase of a detailed design or implementation. Below you will find information on Metrolinx projects currently in the TPAP phase, and those that have undergone a TPAP.

In 2003, the Ministry of the Environment approved the GO Transit Class EA Document (see below), which focused on transit projects common to GO Transit, and allowed projects to proceed effectively and efficiently to meet the growing service demands.

In 2008, the province of Ontario passed Regulation 231/08, Transit Projects and Metrolinx Undertakings, in order to streamline all transit projects identified as being a priority in the province.
