Relief Line

The City of Toronto’s City Planning Division, together with the TTC, is planning a new rapid transit line to connect Line 1 Yonge-University, downtown to Line 2 Bloor-Danforth, east of the Don River. This line will relieve crowding on Line 1 Yonge-University, at Bloor-Yonge Station, and on the surface transit routes coming in and out of downtown. 

Preliminary work is well underway for the Relief Line with several crews conducting field testing along and in the vicinity of the approved alignment. Field testing involves obtaining ground samples, requiring some drilling and coring, to gather essential data. For up-to-date information on this preliminary work, visit our dedicated page for Relief Line field testing.
