TORONTO: In a race against time to prepare the city’s public transit infrastructure for the upcoming FIFA World Cup, the Toronto Transit Commission (TTC) has announced major service disruptions on its busiest subway line starting next week. The sweeping maintenance blitz on Line 1 (Yonge-University) aims to eliminate emergency “slow zones” that have plagued the network, ensuring maximum transit efficiency before global soccer fans descend on the city.
The service restrictions will roll out in phases. From June 1 to June 4, subway service between Sheppard West and St. George stations will wrap up early, terminating just before midnight. This will be followed by a full, day-long closure of the same segment on Sunday, June 7, to allow engineering crews uninterrupted access to the tracks. The most severe disruption, however, will hit commuters on Monday, June 8, when trains between Wilson and Lawrence West stations will be forced to share a single track for bi-directional travel.
TTC Chief Executive Officer Mandeep Lally stated that train headway—the time interval between consecutive trains—could stretch up to 25 minutes on Monday. Lally explained that Monday was strategically chosen for this high-impact work as ridership is historically lower at the start of the workweek. The TTC had initially hoped to execute these heavy repairs over the upcoming weekend, but rescheduled the work to avoid disrupting the massive crowds heading to the Rogers Stadium for the highly anticipated Bruno Mars concert.
TTC Chief Operating Officer Fort Monaco confirmed that the June 8 restrictions would trigger notable travel delays, making regular operational speeds impossible. Normal service on the route is not expected to restore fully until Tuesday, June 9, at around 6:00 AM. Despite the short-term headache, the agency emphasized that the maintenance will successfully eliminate four of the six active slow zones, where structural track defects had forced trains to crawl at a restrictive 20 km/h.
Once this phase is complete, normal speeds will resume through bottlenecked stretches between Yorkdale, Wilson, Glencairn, Dupont, and St. Clair West stations. While slow zones between Eglinton–Davisville and Museum–St. George will temporarily remain, transit officials express strong confidence that these final issues will be ironed out before Toronto hosts its inaugural World Cup match on June 12.
The structural decay of the subway tracks was identified during a semi-annual laser-assisted geometric survey, a routine inspection used to evaluate rail alignment and stability. Prompted by these findings, the transit agency is now seeking approval for a new $150 million funding package dedicated to an extensive, 10-year track modernization and rehabilitation framework.
