Launch shafts and a portal will be constructed on the west side of the existing GO tracks for the beginning of the Ontario Line tunnels. From here, the tunnel boring machines will begin to work their way north, toward Pape Station.

Metrolinx is working with local business owners to minimize the impacts of construction on their properties.

Work is anticipated to begin after financial close for the Northern Civil, Stations and Tunnel procurement package.
