GO Expansion RER New Stations Overview

The GO Expansion RER program, our most ambitious program yet, will transform the region with frequent, two-way all-day rail service, more than doubling the number of GO Transit riders by 2031. Sixty-six GO Rail stations currently serve our customers daily; adding more stations to the network will mean 350,000 more people will live and work within walking distance to the frequent rapid transit network with better options to travel locally and connect with the entire region.

On June 28, 2016, the Metrolinx Board of Directors approved 12 potential new stations for further analysis in support of GO Expansion and the City of Toronto’s SmartTrack program. These stations were identified through a network-wide analysis and included locations which are part of existing municipal and public growth plans. Since 2016, station designs have significantly matured informed by on-the-ground surveys, updated GO Expansion operating patterns, revised municipal growth plans, stakeholder and public engagement. On March 8, 2018, that work was presented to the Metrolinx Board of Directors in the updated GO Expansion New Stations Preliminary Design Business Case Analysis with a recommendation to continue delivery of those 12 stations, and move one other station, Park Lawn, which was not part of the original 12, forward through the business case process.

New Station Evaluation Process and Methodology

Like all major infrastructure projects, new stations analysis has relied on a progression of decisions to guide their advancement.

Stage 1 - Identified an initial list 120+ sites using key site and network considerations.
Stage 2 - Focusing analysis: Analyzed site factors, service considerations and historical requests, to scope list to 50+ sites.
Stage 3 - Evaluating: Analyzed strategic, economic, technical/operational and cost/revenue considerations of 50+ sites.
Stage 4 - Municipal and Public Engagement: Consultation, feedback and review of 50+ sites.
Stage 5 - Refining the list: Following public engagement, scoped sites for further analysis.
Stage 6 - Business case analysis (we are here).

Initial Sites Evaluated

120+ List of Initial Sites

We initially looked across the network and identified 120+ potential station locations, taking into consideration municipal interest, current station spacing, transportation connectivity, ridership potential and space availability for a station.

50+ List of Locations Evaluated

In order to focus the list of 120+ sites to 50+, a review based on strategic and technical feasibility criteria was done and a score was given to each potential location. All sites on the 120+ list that were identified as candidates in public documents (e.g. municipal plans, SmartTrack) or previous projects, but not related to GO Expansion, were included in the 50+ list of stations.

The 50+ locations were then analysed looking at strategic, economic, technical/operational and cost/revenue considerations and narrowed down to 17 potential station locations (or clusters of comparative station sites) that were examined in more detail using an initial business case (IBC) analysis.

New Station Business Cases

The Business Case is a ‘living document’ used throughout the entire decision-making lifecycle of a major project. This lifecycle – the transition from options analysis to planning and design of a preferred option and finally to delivery and operations – relies on a progression of decisions to guide an investment’s advancement. The Metrolinx business case is just one of several factors that is used in making a final decision. It is important to recognize that there are a wider range of factors that are considered as part of final decision-making process.

Over the course of an investment's lifecycle, four Business Case documents will be prepared to provide the level of evidence that is appropriate at each stage.

Initial BC Preliminary Design BC Full BC Post In-Service BC
What is the purpose? The Initial Business Case reviews variations of the preferred investment(s) from the Strategic Business Case as part of detailed planning. This Business Case selects a preferred option for further refinement and design. The Preliminary Design Business Case selects a specific option and reviews different approaches to refine or optimize it. This Business Case leads to a single preferred option for final development. The Full Business Case defines a specific option (including benefits realization, financing, and delivery plans) for procurement. The Post In-Service Business Case reviews the actual costs and performance of the investment.

See our Business Case page for more information.

Initial Business Case (IBC)

For each of the 17 potential stations, an initial business case analysis was performed (looking at the Strategic, Economic, Financial, Operations and Deliverability cases for each location) with consideration for policy, infrastructure, and operational advancements. For more details, see the RER New Stations Initial Business Cases Summary and Ranking Report and individual site-specific IBCs for details regarding methodology and findings.

The results of the IBC analysis provided the basis for the Metrolinx Board Resolution on June 28, 2016, announcing 12 stations to proceed as part of the GO Expansion program. Metrolinx and municipal staff have since been working closely to move the station planning forward for these 12 sites.

Preliminary Design Business Case (PDBC)

In the Metrolinx Business Case lifecycle, the Preliminary Design Business Case (PDBC) takes the IBC results and refines them with more detailed costing and analysis of benefits. The new stations PDBC analysis will capture evolved design concepts, revised modelling methodology, changes in municipal and provincial plans, and updated operating patterns and service plans, since 2016.

PDBCs have been done for all of the 12 announced station sites. In addition, the 5 station sites that were deferred by the Metrolinx Board have had their IBCs updated. The analyses for all 17 sites can be viewed here.

Recommendations related to each of the 17 stations were brought to the Metrolinx Board of Directors on March 8, 2018 and are available here.

A New Stations Modelling Backgrounder technical report, published on Friday April 13, 2018, is available here.

* Following the Board’s June 2016 direction, two additional IBCs were initiated for the Highway 27-Woodbine site and the Walkers Line site.
