Stage 1 of the GTA West Transportation Corridor Planning and Environmental Assessment (EA) study considered all transportation modes and their ability to address the future transportation demands by 2031. The outcome of Stage 1 was a multi-modal Transportation Development Strategy (TDS). This strategy made recommendations for optimizing the existing transportation network, improvements to non-roadway transportation modes such as transit and rail, widening of existing highways, and a new transportation corridor.

Stage 2 will focus on identifying the route and developing the preliminary design for the new transportation corridor. The new corridor will extend from Highway 400 (between Kirby Road and King-Vaughan Road) in the east to the Highway 401/407 ETR interchange area in the west, and will feature a 400-series highway, a transitway, and potential goods movement priority features. The study area for the new transportation corridor is shown on the Home page.

This new transportation corridor is only one component of the full suite of multi-modal recommendations that are documented in the Transportation Development Strategy (TDS) that was completed in November 2012 as part of Stage 1. These recommendations included transit improvements, transportation demand management measures (e.g. expansion of the Ministry’s overhead electronic message signs), opportunities to optimize the existing transportation system, as well as widening of several provincial facilities in the western GTA. All of these recommendations will be reviewed and pursued separately by MTO and other agencies, as appropriate.

In addition to examining alternative routes for the new transportation corridor, the Project Team will examine alternatives for interchanges, bridges, and other key elements of the corridor. A comprehensive analysis of technical and environmental factors will be undertaken and in consultation with the public, stakeholders, municipalities, First Nation and Métis communities, and government agencies to identify the preferred alternative for the new transportation corridor.

Public Information Centres (PICs) and Community Workshops will be held during this study to provide the public with the opportunity to discuss the project and provide input to the Project Team. The first round of Community Workshops (July and August 2014) introduced the study to stakeholders, sought feedback on key features within the study area and where the transportation corridor should be located, and advertised membership opportunities for the Community Advisory Group as well as the Greenbelt Transportation Advisory Group. The first round of PICs were held in November and December 2014 and sought feedback on the long and short list of route alternatives, potential interchange locations, crossing road treatments and goods movement priority features. Refer to the Consultation page for more details.

An Environmental Assessment Report (EA Report) will be prepared and made available for public review at the completion of the study. Refer to the EA Process page for more information.
