Ontario Taking Next Steps to Build the Yonge North Subway Extension

August 6, 2025

• We are taking the next steps to build the Yonge North Subway Extension, awarding a major contract for tunnel design and construction that will extend Line 1 into York Region.
• The contract also includes construction of support headwalls for future stations and emergency exit buildings.
• Once complete, the Yonge North Subway Extension (YNSE) will accommodate over 90,000 daily trips and will put 26,000 more people within a 10-minute walk of transit.
• The YNSE will reduce daily travel times by up to 22 minutes on a trip from Markham to downtown Toronto, getting commuters where they need to go faster.
• Ontario’s bold $70-billion transit plan for the Greater Toronto Area — which includes the all-new Ontario Line, the Scarborough Subway Extension, the Yonge North Subway Extension and the Eglinton Crosstown West Extension — is the largest transit investment in North America.
• As we get shovels in the ground on this critical project, we’re helping to keep thousands of workers on the job and building the infrastructure that will boost Ontario’s economy and help thousands of York Region commuters get where they need to go faster and more conveniently.
