Over the next few weeks, TTC crews are repairing leaks at track level on Line 1 (Yonge - University) between Dupont and Spadina Stations. This project is part of TTC’s regular subway maintenance program, so crews can only work at night when the subway is not operating.

Overnight, from about 1:30 until 5 a.m. Wednesday, December 28, Thursday, December 29 and Friday, December 30, crews are drilling holes into areas of the tunnel walls to insert injectors. Although the majority of the work is underground, the drilling activity may at times carry noise to street level through the ventilation shafts on Spadina Road south of the Dupont Street.

TTC crews again work on the project from about 1:30 until 5 a.m. from Tuesday, January 3 until Friday, January 13.
