TTC signal work closes part of Line 1 this weekend

Street festivals lead to temporary diversions

This weekend, July 29-30, TTC crews will continue installation and testing of the new Automatic Train Control (ATC) signal system, requiring Line 1 Yonge-University to close between St George and Sheppard West (formerly Downsview) stations.

Because of on-street construction around Eglinton West, St Clair West and Dupont stations, shuttle buses will run between Sheppard West and Lawrence West stations only. To supplement shuttle service and move customers more efficiently to the Yonge St. side of Line 1, the TTC is doubling service on nine east-west bus and streetcar routes in the closure area.

Surface routes with extra service are:

  • 7 Bathurst
  • 14 Glencairn
  • 32 Eglinton West
  • 52 Lawrence West
  • 84 Sheppard West
  • 96 Wilson
  • 109 Ranee
  • 127 Davenport
  • 512 St Clair

To provide better bus service, parking will be restricted on Bathurst St. between Bloor St. and Barton Ave.

Wheel-Trans buses will operate during the closure for customers requiring an accessible connection. Customers can speak with any TTC staff to request the service.
Dupont and Glencairn stations will be closed. All other stations will be open for fare sales and access to surface vehicles.

During the closure, crews will run mock service to test the new ATC system between Spadina and Wilson stations and perform other essential work in preparation for the opening of the Line 1 extension to York Region.

This is the eighth of 11 closures on this portion of Line 1 in 2017 as the TTC modernizes its train operations. When installation is complete in 2019, ATC will result in a more modern and reliable signal system that will allow for a 25 per cent increase in the number of trains operating on Line 1.

While the TTC does much of its subway maintenance work at the conclusion of service each night, it continues to require weekend closures to complete ATC and state-of-good-repair work, like replacing track and maintaining switches. One weekend of work during a closure is equivalent to about five weeks of nightly work.

Here is a video explanation of signal systems, Automatic Train Control, and why the TTC needs weekends to complete critical work.

Regular subway service resumes Monday at 6 a.m. The next scheduled subway closures are:

  • Aug. 12-13 - Line 1 Yonge-University: Sheppard West to St George for ATC signal work.
  • Aug. 19-20 - Line 2 Bloor-Danforth: Kipling to Islington for track work.
  • Aug. 26-27 - Line 2 Bloor-Danforth: Broadview to St. George for TTC and City work.

Beaches Jazz Festival
This Thurs., July 27 – Sat., July 29, the annual Beaches Jazz Festival will be in full swing, resulting in closures on Queen St. E. from Woodbine Ave. to Beech Ave.  between 6 - 11 p.m. each day. During these times, the 501 Queen replacement bus will turn back at the Woodbine Loop (Queen St. E. and Kingston Rd.), the 64 Main Street bus will divert via Wineva Ave., Alfresco Lawn, Lee Ave., Williamson Rd. and Southwood Dr.

Throughout the summer, Toronto is alive with numerous events, celebrations and festivals as well as major construction projects that will impact service for TTC customers. Up-to-date information is available at and by following @TTCNotices on Twitter.
