If you rely on the TTC to move through the downtown core, this weekend is one of those moments where planning ahead is not optional. The Toronto Transit Commission will temporarily shut down a central stretch of Line 1 Yonge–University for planned track work, cutting subway service through a busy corridor that normally links the University side of downtown to major office towers, cultural stops, and weekend foot traffic.
The closure begins at 11 p.m. Friday and is scheduled to run until around 6 a.m. Monday. During that window, there will be no subway service between St. Andrew and St. George stations, affecting a six-station segment that typically acts as a fast downtown spine. Riders heading to late-night plans on Friday, early weekend shifts, or downtown events should expect longer travel times and a different commute rhythm from the one they are used to.
What makes this shutdown especially disruptive is a detail that changes everything: shuttle buses will not operate between the closed stations. On many closure weekends, shuttle buses provide a slower but direct replacement service. This time, that option is off the table, meaning most riders will need to stitch together alternate bus and streetcar routes or use a subway transfer strategy that avoids the closed stretch entirely.
The TTC says four stations will be fully closed throughout the shutdown: Museum, Queen’s Park, St. Patrick, and Osgoode. Meanwhile, St. George and St. Andrew will remain open, not for through service, but so customers can connect to surface routes and access fare services such as Presto loading and entry points. In practical terms, you may still be able to enter or exit at those endpoints, but you will not be able to ride the train through the middle section.
The TTC’s guidance is clear: think in terms of connections. If you are trying to move north or south on the Yonge side during the closure, using Line 2 as a bridge may be the simplest approach. Riders can take Line 2 to Bloor–Yonge and then connect back to Line 1 to reach St. Andrew on the south side of the affected area. For many weekend trips, that extra transfer is still faster than crawling through downtown traffic on a packed surface route.
For those whose usual entry points are inside the closure zone, the TTC has outlined specific surface alternatives. From Queen’s Park, one option is the 506 Carlton streetcar eastbound to connect with College Station, where you can rejoin Line 1 service outside the shutdown area. The 94 Wellesley bus is another key connector, operating between Ossington and Castle Frank while linking to Wellesley Station. This can be useful if you are trying to reach the Yonge corridor without pushing straight through the downtown bottleneck.
If you normally use St. Patrick, the TTC recommends the 505 Dundas streetcar eastbound to reach the Toronto Metropolitan University area. For riders near Osgoode, the suggested move is the 501 Queen streetcar eastbound to Yonge Street and Adelaide Street West. From there, the TTC notes that you can walk about two minutes south to King Station or about five minutes north to Queen Station, depending on your destination and comfort level with short downtown walks.
Accessibility support is also part of the plan. The TTC says Wheel-Trans service will be available for customers who may require assistance during the closure. If you are travelling with mobility needs, it is worth building extra buffer time into your trip, since surface diversions can be unpredictable, especially during busy weekend periods.
The reason for the shutdown is planned track work tied to what transit agencies often call state-of-good-repair. The TTC has emphasized that while much subway maintenance happens after service ends each night, some work requires longer closures to be completed safely and efficiently. For riders, the key takeaway is less about the technical details and more about the ripple effect: downtown routes will be busier, streetcars may feel more crowded, and travel times will vary depending on traffic and boarding volume.
If you are heading downtown for shopping, dining, theatre, or a shift that starts early, aim to leave earlier than usual and choose a backup route before you step out the door. Checking updates right before you travel can also help, especially if surface routes become congested. For the TTC’s official details and route guidance for this specific shutdown, riders can refer to the TTC service advisory for the Line 1 weekend closure.
Service is expected to resume early Monday morning, restoring normal subway travel through the downtown core. Until then, this is a weekend where the best commute tool is a simple plan: know your endpoint station, pick your surface connector, and give yourself the time cushion you would normally reserve for a snow day.
