October 25, 2026 — Toronto. The Toronto Transit Commission (TTC) will end Line 1 Yonge–University service early for four weeknights beginning Monday, Oct. 26, to allow track crews to replace rail components and remove reduced speed zones between Lawrence West and St George stations. The agency will close service at 23:59 each night from Monday through Thursday, Oct. 29, about two hours before normal late-night service, and will run frequent shuttle buses plus Wheel-Trans for customers requiring assistance. The closures include full station closures at Glencairn and Dupont and restricted entrances at St Clair West and Spadina stations, while other stations remain open for PRESTO transactions and bus or streetcar connections.
The TTC’s reduced speed zone list, last updated Oct. 22, shows three slow zones inside the closed section with explicit speed and distance values: southbound St Clair West–Dupont limited to 25 km/h over 279 m (normal 65 km/h); northbound St Clair West–Cedarvale limited to 35 km/h over 582 m (normal 53 km/h); and southbound Cedarvale–St Clair West limited to 40 km/h over 293 m (normal 60 km/h). The TTC lists late November as the target for removing all three, and the agency said a single slow zone can add roughly one to three minutes to a trip. Separately, on Friday Oct. 30 the TTC will end Line 2 Bloor–Danforth service between St George and Broadview at 22:00 for maintenance and advertising installation, with Bay and Sherbourne stations and a Bloor–Yonge entrance closed that night.
Lead
Date/place/event: Oct. 25, 2026 — Toronto. The Toronto Transit Commission (TTC) announced early nightly closures of Line 1 Yonge–University service for four weeknights starting Oct. 26 to permit rail component replacement, tunnel repairs and track-level inspections on the section between Lawrence West and St George stations.
Verified facts
Announcement and schedule: The TTC will end Line 1 service between Lawrence West and St George stations at 23:59 each night from Monday through Thursday, Oct. 26–29, about two hours earlier than normal late-night service. The agency also scheduled an early closure for Line 2 Bloor–Danforth on Friday, Oct. 30, ending service between St George and Broadview stations at 22:00 for planned maintenance and the installation of advertising.
Scope and works: Track crews will use the extra overnight hours on Line 1 to swap out rail components on the closed stretch so that reduced speed zones can be lifted and normal speeds restored. The TTC also plans tunnel repairs close to Dupont Station and inspections of infrastructure at track level throughout the closed section. For the Oct. 30 Line 2 closure, the TTC identified maintenance and advertising installation as the purposes.
Service mitigation: Shuttle buses will run frequently, stopping at every station on the closed routes. Wheel-Trans will be available to customers who need assistance. Glencairn and Dupont stations will be closed during the Line 1 closures, and the Heath Street entrance at St Clair West Station and the Kendal Avenue entrance at Spadina Station will be closed. Other stations on the closed section will remain open for PRESTO card loading, PRESTO Ticket purchases and connections to buses and streetcars.
Disclosed figures and timing: The TTC’s reduced speed zone list, last updated Oct. 22, shows three slow zones inside the Line 1 closed section with specific speed restrictions and lengths: southbound between St Clair West and Dupont limited to 25 km/h over 279 m instead of a normal 65 km/h; northbound between St Clair West and Cedarvale limited to 35 km/h over 582 m instead of 53 km/h; and southbound between Cedarvale and St Clair West limited to 40 km/h over 293 m instead of 60 km/h. The TTC lists late November as the target for removing all three slow zones. The agency says a single reduced speed zone can add roughly one to three minutes to a trip.
Organizations and responsibilities
Toronto Transit Commission (TTC): Announced and scheduled the early closures; responsible for the track component replacement, tunnel repairs near Dupont Station, inspections of infrastructure at track level, station and entrance closures, running shuttle buses, providing Wheel-Trans service, and maintaining the reduced speed zone list (last updated Oct. 22). The TTC provided the target timeframe of late November for removing the three slow zones and the estimate that a single slow zone can add roughly one to three minutes to a trip.
Track crews: Identified by the report as the personnel who will swap out rail components during the overnight closures. Specific contractor names or suppliers are Not publicly disclosed.
Shuttle bus operations and Wheel-Trans: The TTC said shuttle buses will run frequently and Wheel-Trans will be available; the responsible operating entities are the TTC services themselves as described in the notice. Specific service operators or subcontractors are Not publicly disclosed.
Operational and commercial context
Reported operational impact: According to the report, the four-night Line 1 early closures aim to lift three explicit reduced speed zones that currently constrain train speeds across short track lengths, restoring higher line speeds and reducing trip time impacts that the TTC quantifies as roughly one to three minutes per speed restriction. The Oct. 30 Line 2 early closure is separate and attributed to maintenance and advertising installation; that closure ends about four hours earlier than the subway’s typical 02:00 end of service.
Historical context in the report: The article notes that a longer stretch of Line 1 was closed early in June (June 1–4) to remove four reduced speed zones ahead of FIFA World Cup 2026 operations; that program included replacing track hardware northbound between Dupont and St Clair West. At that time the TTC CEO Mandeep S. Lali said the subway had six speed restrictions, down from nearly 30 about ten months earlier. Those prior statements are reported information from the June program as described in the article.
