This article details upcoming service changes on the TTC network, most of which will occur on Sunday, November 17.

Updated Nov 14 at 1:10pm: The section about supplementary service on many routes and the possible future for 2025 has been clarified based on additional info from the TTC.

Major changes include:

• Re-opening of St. Clair West Station Loop. 512 St. Clair streetcars return there on Thursday, November 14, and bus service 33 Forest Hill, 90 Vaughan and 126 Christie on Sunday, November 17.
  • Note that routes 33 and 126 will return to independent operation and the buses will not interline.
  • Route 90 will no longer operate south of St. Clair to Bathurst Station.
• The final stage of overhead reconstruction will occur on the western end of 509 Harbourfront and 511 Bathurst.
  • 509 cars will operate to Exhibition Loop until November 24 as part of the extra service for Taylor Swift concerts. After that, they will run only to the loop at Queens Quay and Spadina.
  • 511 Bathurst cars will be rerouted to Union Station effective November 14. A shuttle bus will operate from Queen & Bathurst to Exhibition Loop beginning November 17. (The 510D Spadina bus already serves Exhibition Loop.)
• The 35 Jane bus will operate with split service on the regular 35A and the via Hullmar 35B branch at the north end of the route at all times, not just in peak periods.
• Service in southwestern Scarborough will be modified:
  • The 12D Kingston Road service to UTSC will now operate weekday midday and early evenings in addition to the existing peak period service.
  • The 12C St. Clair branch will be removed
  • The 69 Warden South bus will operate to the Barkdene Hills area at all hours replacing the 12C Kingston Road branch.
  • A new route 117 Birchmount South will operate between Warden and Victoria Park Stations via Kingston Road.
  • Routes 69 and 117 will interline at Warden Station so that passengers can ride through between them.
• The 110C Islington South branch to Kipling Loop is rerouted to better serve Lakeshore Village. Northbound buses will run north on Kipling, then east via Birmingham, Twelfth, Garnett James, Ninth and Birmingham to Islington. Northbound buses will no longer operate on Lake Shore and Thirteenth.
• The stopping pattern for 54 Lawrence East, 954 Lawrence East Express and 154 Curran Hall will be standardized so that all Lawrence corridor services use the same stops in the SRT replacement corridor. Hours of service on 154 Curran Hall will be corrected to match the former 54B service which it replaced.
• Service on 304 King Night and 305 Dundas Night cars will improve from every 20 to 15 minutes.
