Yonge North Subway Extension Advance Tunnel project

The Yonge North Subway Extension will bring TTC Line 1 service north from Finch Station through north Toronto to Vaughan, Markham and Richmond Hill – with five new stations along a route of approximately 8 km. The extension will save riders up to 22 minutes a trip from Markham to downtown Toronto. A newly proposed transit hub at Bridge Station will make it even easier to connect to GO trains, GO buses, and regional and local transit routes.

North End Connectors, comprised of Ghella, Aecon and FCC Construcción, will design and construct an approximately 6.3-kilometre tunnelled segment, launch and extraction shafts, and headwalls for emergency exit buildings and stations. The scope of work also includes the supply of tunnel boring machines, the installation of tunnel liners and other supporting activities.
