TTC continues geophysical investigations near Bloor and Yonge Streets, starting March 28



Since Monday, June 1, 2020, TTC contractors have been conducting geotechnical investigations, including drilling boreholes, as part of a future project to expand Bloor - Yonge Station. Starting Monday, March 28, the contractors are working in the sidewalks on both sides of Bloor Street East from east of Yonge Street to east of Park Road.

Drilling crews are at each test-pit location for two to three weeks. They work Mondays to Fridays from 7 a.m. until 7 p.m. Work zones may block sidewalks and traffic lanes. Equipment and trucks will be present on the roadway, as the crews work at each site. They may also return to previous sites after finishing the initial investigation, if necessary, to repair the asphalt or replace granite pavers.

The contractor crews maintain access to sidewalks and properties at all times. They may also temporarily paint white lines on the roadway. Expect noise and vibration from drilling, hydro-vacuuming and equipment.

Geophysical investigations near Bloor and Yonge Streets continue “until May”, meaning as late as until May 31.


The TTC and the City of Toronto intend to expand the capacity of the Bloor - Yonge subway junction — Bloor Station on Line 1 Yonge - University and Yonge Station on Line 2 Bloor - Danforth.
