Libby TBM Reaches King West Station After 1.3 km Drive
Libby, the first tunnel boring machine (TBM) on the Ontario Line, completed its drive into the future King West Station after excavating about 1.3 kilometers. Starting from a launch shaft just east of Exhibition Station in April, Libby installed roughly 780 concrete lining rings and delivered a finished tunnel that will carry eastbound trains. Workers positioned the machine in the station site at King Street West and Bathurst Street on 6 November 2026 for testing and maintenance before its next assignment.
Where Libby Is Headed Next and How Corkie’s Drive Runs in Parallel
After inspections and servicing at King West, Libby will resume tunnelling west toward the planned Chinatown Station at Queen Street and Spadina Avenue. A second TBM named Corkie has begun the parallel drive for the westbound tunnel; project planners expect Corkie to arrive at King West in December 2026. Both machines — named for neighborhoods at the line’s ends, Liberty Village and Corktown — operate from the Exhibition launch shaft and will bore a roughly 6 km corridor at depths near 40 metres to the portal at Don Yard west of the Don River.
What This Milestone Means for the Overall Tunnel Program
Libby’s arrival marks completion of about one-fifth of the line’s main central-tunnel section. Beyond the central 6 km tunnel segment through downtown, the Ontario Line contains a second principal tunnel section that runs beneath Pape Avenue northward from Gerrard Station to Minton Place at the Don Valley Parkway. The downtown tunnel and station construction form the first of the two major tunnel contracts; Ontario Transit Group leads construction for that package.
Stations in the Central Zone and Network Connections
The TBMs will pass beneath six future downtown underground stations: King West, Chinatown, Osgoode, Queen, Moss Park and Distillery District. Osgoode and Queen will provide direct interchanges with the existing TTC Line 1, improving transfer flows. The downtown tunnel works included major excavation completion earlier in the year for King West, Moss Park and Distillery District, with Chinatown nearing final excavation stages at that time.
Who’s Building the Line: Contracts and Delivery Model
Ontario Line delivery divides into four major contract packages that allocate design, construction, finance and long-term operations responsibilities:
1) Rolling Stock, Systems, Operations and Maintenance (Connect 6ix) — The contract covers train procurement, systems design and installation, financing, operations and 30 years of maintenance. This contract was awarded 17 November 2022.
2) South Civil, Stations and Tunnel (Ontario Transit Group) — This package delivers the 6 km twin tunnels from Exhibition to the Don Yard portal and seven stations. The fixed-price contract was awarded 9 November 2022.
3) Pape Tunnel and Subway Stations (Pape North Connect) — This work includes about 3 km of twin tunnel beneath Pape Avenue and two underground stations. The contract signed on 1 August 2026 set a target price of CAD 4.32 billion.
4) Guideway and Stations (Trillium Guideway Partners) — This package builds roughly 3 km of elevated guideway and five elevated stations; the agreement was signed 20 February 2024.
Projected Ridership and Local Impact at King West
King West Station will add metro access to Toronto’s Fashion District and place approximately 27,000 residents and 24,200 jobs within comfortable walking distance of rapid transit. Metrolinx forecasts for 2041 estimate about 5,100 peak-hour users at the station: roughly 3,000 boardings onto Ontario Line trains, 2,100 alightings, and about 2,400 transfers in the same period. The station also connects to TTC’s 504 King and 511 Bathurst streetcar routes, distributing passenger flows across surface and rail networks.
Network Capacity: Daily Demand and Congestion Relief
The full Ontario Line will run approximately 15.6 km from Exhibition Place to the vicinity of Don Mills Road and will include 15 stations with over 40 connection points to other transit systems. Planners estimate the line will carry about 390,000 passengers per day once in service, and they project a reduction in crowding on Line 1 between Bloor–Yonge and Wellesley by up to 15%. Construction activity is expected to support roughly 4,700 jobs per year during peak build-out.
Timeline, Funding and What to Watch Next
Metrolinx and Infrastructure Ontario awarded the primary fixed-price design-build-finance contract for the downtown civil works in November 2022. The Ontario government manages delivery through Metrolinx while the federal government provides more than CAD 4 billion in funding. City updates indicated a target completion year of 2031 in planning documents as of late 2025, though staging, testing, and commissioning milestones will determine the final in-service date. Next visible project milestones include Corkie’s arrival at King West, completion of Chinatown excavation, station fit-out progresses, and commencement of systems integration under the Connect 6ix program.
