Yonge North Subway Extension progress moves Markham one step closer to transit relief
By Gene Pereira, Local Journalism Initiative reporter
Commuters in Markham and across the Greater Toronto Area are one step closer to relief from gridlock and soaring fuel costs as Ontario achieved a significant milestone on the Yonge North Subway Extension.
The completed excavation of the tunnel launch shaft sets the stage for fast, affordable, and reliable public transit, cutting out long bumper-to-bumper delays on heavily congested corridors and offering a budget-friendly alternative to filling up at the pump.
By expanding the Toronto Transit Commission’s Line 1 subway nearly eight kilometres north from Finch Station through Vaughan, Markham, and Richmond Hill, the project aims to move over 94,000 daily riders while significantly cutting time off routine drives across the region.
For Markham residents, the arrival of rapid heavy rail service marks a major transformation in local transit. The extension will bring transit access directly to growing communities through new stops, including Bridge and High Tech stations. Markham commuters will benefit from seamless connections to regional transit options, such as GO train and bus lines, making trips to school, work, local businesses, and essential services much faster.
By bringing transit within walking distance of nearly 23,000 jobs, the project offers a practical and dependable solution that reduces reliance on personal vehicles and lowers local vehicle emissions.
“The continued progress of the Yonge North Subway Extension is encouraging news for residents of Markham-Unionville and communities across York Region,” said Billy Pang, MPP for Markham-Unionville. “This important project will provide faster, more reliable transit, reduce congestion, and make it easier for people to reach work, school, local businesses, and essential services.
“As construction moves forward, we remain committed to building a more connected and accessible transportation network that supports our growing communities and improves quality of life for residents.”
To prepare the site for the upcoming work, crews excavated nearly 70,000 cubic metres of soil to create a shaft extending 10 metres underground. Over 11,000 cubic metres of concrete and 860 tonnes of steel reinforcement were used. This site will serve as the starting location for two massive tunnel boring machines tasked with digging twin 6.3-kilometre tunnels.
As utility relocation continues ahead of main tunnelling and station construction, the project, say government officials, is already generating momentum by supporting 4,300 jobs annually and driving over $3.6 billion in economic benefits.
They also emphasized the strategic importance of expanding rail options north into York Region.
“As part of our government’s $236 billion capital plan to build and protect Ontario, we are working with our partners to plan transit-oriented communities along the extension, including at the High Tech and Bridge stations,” said Todd McCarthy, Acting Minister of Infrastructure.
“These vibrant, mixed-used communities will deliver more than 40,000 new homes, create over 4,000 jobs during construction per year, support nearly 10,000 new long-term jobs and help to increase transit ridership, reduce gridlock and drive local economic growth.”
Local representatives highlighted the specific benefits expected for Markham residents once trains begin running.
“This transformative investment will connect more people to jobs, housing and opportunity across Toronto and the GTA – protecting Ontario’s growth for years to come,” said Paul Calandra, MPP for Markham-Stouffville.
A second subway stop in Vaughan will get the GTHA moving, believes Logan Kanapathi, MPP for Markham–Thornhill.
“This project is a key pillar in our plan — the largest and most ambitious transit expansion in North America, along with massive improvements at the Rutherford, Maple, and King City GO stations,” he said.
The extension forms a major piece of Ontario’s broader $70 billion public transit investment, which includes the Ontario Line, Scarborough Subway Extension, and Eglinton Crosstown West Extension. With federal funding support of $2.24 billion and key agreements established with municipal partners, the work underway in Markham lays the groundwork for a more connected region.
