A stretch of the Bloor-Danforth subway line will be closed to commuters overnight Wednesday, beginning at 10 p.m.
There will be no subway service between Keele and Ossington stations as crews work to fix a damaged portion of a tunnel at Dundas West Station.
TTC shuttle buses will operate between the stations during the closure.
According to TTC officials, full subway service is to resume by 6 a.m. on Thursday.
Subway service was disrupted for approximately seven hours on Tuesday following a buildup of mud, water and other debris on the tracks at Dundas West.
The flooding occurred after a contractor accidentally punctured a hole in the subway tunnel. Provincial transportation agency Metrolinx is investigating the incident.
