A major milestone in Toronto’s transit infrastructure has arrived. Metrolinx announced the delivery of the first tunnel boring machine (TBM) for the Yonge Line 1 North Subway Extension in October 2026, marking a significant step toward expanding subway service into York Region. The $6.3-kilometre twin tunnel project will connect Finch Station to five new stations—Steeles, Clark, Royal Orchard, Bridge, and High Tech—terminating near Richmond Hill Centre. After years of planning challenges and cost reductions, the project has shifted from a fully underground design to a hybrid approach combining underground and at-grade sections. While tunneling preparations are underway with demolitions near future stations and monitoring equipment installed along the route, substantial work remains. The station-building contract hasn’t been awarded, with selection expected in 2027. For GTA real estate investors and homebuyers, this extension signals long-term regional connectivity improvements and potential transit-oriented development opportunities similar to the successful Toronto-York Spadina Extension.
