Metrolinx is currently exploring the potential long-term impacts of COVID-19, however the specific impacts of COVID-19 on Ontario Line have not been forecast. As of the date of distribution of this business case, the COVID-19 pandemic has had a material impact on the movement of people and goods, including travel patterns and behaviours. Readers of this business case should consider its findings in this context. 2 3 Ontario Line Preliminary Design Business Case Summary Ontario Line Preliminary Design Business Case Summary The Ontario Line will provide 15.6 km of new rapid transit in Toronto... 3.7 km at-grade on 3.1 km elevated shared corridors 8.8 km underground New maintence & storage facility To maintain a modern fleet of up to 44 trains 15 stations ... increasing capacity With connections to Fast and frequent to meet demand on existing and in-delivery subway services ...and to Toronto’s opening day and rapid transit... extensive surface into the future...

Coverage and Network Resilience The Ontario Line has been designed and planned to make use of advanced driverless trains, subway tunnels, existing rail corridors, and elevated structures to provide extensive rapid transit coverage in the City of Toronto. This combination of corridor types and advanced technologies will reduce costs and expedite the delivery of the line.

Metrolinx has developed all costs to reflect design a “Reference Concept Design” (RCD) for the refinements and conducted further ridership, revenue, Ontario Line (shown in Figure 2) that builds upon and benefits forecasting. the IBC and optimizes the project to improve its benefits while managing costs and delivery risk. As a result, PDBC benefits and costs vary from those This RCD is used to: presented in the IBC. • define a comprehensive and deliverable scope for the project; • determine a budget and construction schedule for use in project approvals; • define benefits and how they are realized; and • identify key risks and identify ways to mitigate them. 10 11 Ontario Line Preliminary Design Business Case Summary Ontario Line Preliminary Design Business Case Summary PDBCs compare multiple variants of Table 1: Ontario Line Evolution from IBC to PDBC preferred option identified at the IBC stage across the four cases in order to: PDBC Alignment with IBC PDBC Alignment with Refined Analysis Scope • Demonstrate that multiple variants Operating Concept Operating Concept were considered and analyzed; Train Size 100m (five car) trains 80m (four car) trains • Confirm that an optimal variant has been 750 passenger per train capacity 600 passenger per train capacity identified for further development; and • Identify key lessons learned to inform the continued development of the option through Frequency 40 trains per hour (TPH) in peak 34 TPH (2030-2041), 40 TPH (2041 on) in peak to the Full Business Case (FBC) stage. 12-24 TPH off-peak 24 TPH in off-peak This PDBC includes two operating variants (described in Table 1) that were developed based Rationale for Inclusion Demonstrates how the IBC Explores how the benefits and on lessons learned since the completion of the IBC: operating concept performs on costs of the Ontario Line can the IBC operating concept and a Refined Operating the optimized alignment be further optimized with a refined operating concept Concept.
