Overnight Utility Investigation and Hydrovac Excavation Work on Yonge Street and Bloor Street East

Timeline: Starting as early as June 16 for approximately 5 weeks

Starting as early as June 16, 2025, for approximately 5 weeks, the TTC will conduct utility investigation work for the Bloor-Yonge Capacity Improvements Project. The work will include hydrovac excavation on both sides of Yonge Street, between Cumberland Street and Bloor Street, and on both sides of Bloor Street East, between Yonge Street and Church Street. Work will take place overnight, Monday nights to Saturday mornings, from 9:00 p.m. to 5:00 a.m. Lane closures on Yonge Street and Bloor Street East can be expected, however the streets will remain open to traffic. Diversions for pedestrians, cyclists, and vehicles will be accommodated around the work sites. The TTC will request a paid duty officer to be present at each site to help guide cyclists and motorists.

The work will require excavation machinery, as well as vehicles moving in and out of the work sites. A high-pressured vacuum system mounted on a truck will be used to hydrovac the work sites. The work will also include utility pipe flushing to remove sediments and deposits. Noise will be evident when work is in full operation.

These dates and timelines are subject to change depending on weather and site conditions.

Preparatory Work to Expand Bloor-Yonge Station

Bloor-Yonge Station is the busiest subway station on the TTC. The original station opened in 1954 and now requires expansion and modernization to accommodate future TTC ridership and neighbourhood density.

The project includes significant upgrades to enhance customer safety, accessibility and service quality.

Improvements include:

A new eastbound Line 2 (Bloor-Danforth) passenger platform
An enhanced westbound Line 2 passenger platform created by reconfiguring the existing shared centre platform
Expansion of both northbound and southbound Line 1 (Yonge-University) passenger platforms
Enhanced concourse level
New elevators, escalators and stairwells to improve station circulation
A new accessible subway entrance at 81 Bloor Street East

What to Expect

The first phase of preparatory construction did not impact subway service or access to Bloor-Yonge Station.
Preparatory work started in May 2023. In order to build a new, accessible subway entrance at 81 Bloor Street East (former site of The Firkin), the TTC removed the existing structures at 81 Bloor St East, and 40/42 Hayden Street. The TTC also removed the former carwash at 830 Church Street beside the Toronto Reference Library to build a future fan building to enhance air circulation at the station.
There were temporary reductions in the Sherlock Holmes Laneway and short-term walkway closures to install construction hoarding beside the Toronto Reference Library.
The first phase of utility relocations was completed as of October, 2024. Some additional preparatory works may take place in advance of major construction.
Phased reductions on the sidewalks and curb lanes were implemented on Bloor Street East, between Yonge Street and Park Road.
Access to businesses and residences was maintained at all times.
Work hours were typically Monday to Friday from 7 a.m. to 7 p.m. Extended, weekend, or overnight work hours were communicated to the community well in advance.
