Several service changes on the Toronto Transit Commission (TTC) took effect Sunday to accommodate infrastructure and restoration projects across the city, the public transit agency says.
The changes will affect certain subway, streetcar and bus routes, the TTC said in a news release Wednesday.
Here’s everything commuters need to know as the adjustments roll out.
Water main construction on King Street W.
Perhaps the most impactful change comes as a result of the city’s water main replacement on King Street W. The construction will take place between Close Avenue and Dufferin Street, as well as between Portland Street and Spadina Avenue.
The 503 King streetcar will operate as a single branch between Dundas West and Broadview stations.
The 504C King will see replacement buses operate between Sunnyside Loop (Roncesvalles Avenue) and the Distillery Loop (Front Street E. and Cherry Street) seven days a week.

The 503 Kingston Road streetcar route replacement buses will also be extended west, ending at Dufferin Gate Loop, while the 508 Lake Shore streetcar route service will be suspended.
The move is part of the TTC and the city’s plan to replace streetcar tracks and water mains, which will take place between November and next August.
It’s the second time in two years construction will affect transit service in the area, forcing diversions and bus replacements — something residents and commuters told CBC Toronto in September is causing concern.
At the time, TTC spokesperson Stuart Green said the work needed to be done as the track had reached its lifespan of around 15 years.
In 2025, the TTC repaired and replaced streetcar tracks in the intersection of King Street W. and Dufferin Street ahead of the World Cup.
Adjusted schedules on lines 1, 2, 5
The TTC is adjusting weekday service on Line 1 Yonge-University and Line 2 Bloor-Danforth to improve reliability. The public transit agency says customers will also benefit from reduced travel times and more frequent service all day long on Line 5 Eglinton.

Service restored on Queen streetcar
Following construction at the Long Branch Loop, service to the area on the 501 Queen and 507 Long Branch streetcars will be restored. Replacement buses will stop operating, the TTC said.
Enhanced service to Sunnybrook Hospital
The public transit agency says it will be extending the 52F Lawrence West bus route to Sunnybrook Hospital. The 11B Bayview bus route will also operate between Lawrence Station and Sunnybrook Hospital.
The 52F Lawrence West will have additional early morning and late evening services, while the 11B Bayview route will have new late evening service on weekends.
The move means the 124 Sunnybrook and 11C Bayview bus routes will be discontinued.
Several bus routes renamed, adjusted
Several express bus routes have been renamed or adjusted as of Sunday, the TTC says.
The 903 Kennedy Station-Scarborough Express bus route, which runs from Kennedy Station to Centennial College Bus Terminal, will be renamed to 903 Kennedy-Progress Express to better reflect the route’s destination.
The 904 Sheppard-Kennedy Express will also be renamed to 904 Don Mills-Scarborough Express to reflect its new route, which will operate between Scarborough Centre and Don Mills stations. The change means the route will no longer service the Scarborough Busway between Scarborough Centre and Kennedy stations.
Service on the 939 Finch Express will be adjusted to improve accessibility in Scarborough. The 939C Finch Express buses will operate in the midday and early evening periods on weekdays and in the morning and afternoon periods on weekends. The move, once again, means the bus route will no longer service the Scarborough Busway between Scarborough Centre and Kennedy stations.

Service on the 934 Kennedy Express will be reintroduced during peak periods on weekdays to improve access between Kennedy Station and northern Scarborough, the TTC said.
The 902 Markham Road Express and the 995 York Mills Express bus routes will have added service in the early evening on weekdays and in the morning and afternoon on weekends.
Lastly, the 985 Sheppard East Express bus route will also have increased service during the midday period on weekdays. The public transit agency says the changes will improve express bus service across Scarborough.
The 29C Dufferin (Wilson Station-Exhibition [Princes’ Gate]) will resume its regular route through Exhibition Place via Nunavut Road, Nova Scotia Avenue and Manitoba Drive.
Service will be removed from the 43C Kennedy (Kennedy Station-Village Green Square) in the early morning, morning peak and afternoon peak periods. The change was approved in the 2024 Annual Network Plan, the TTC says, and means customers will have to access alternative service at the Kennedy Road stop at Village Green Square.
The 43B (Kennedy Station-Scarborough Centre via Progress) will have service restored in the early evenings on weekdays.
The TTC will improve service on the 73 Royal York bus route in the morning, midday and afternoon peak periods on weekdays. But the change means service will be removed from the 73D Royal York (Royal York Station-Albion) during the morning and afternoon peak periods on weekdays and instead replaced with improved service on the 73B Royal York (Royal York Station-Mount Dennis Station) and the 73C Royal York (Royal York Station-Claireport).
Zoo, some park, beach routes suspended
The 200 Toronto Zoo, 201 Bluffer’s Park, 202 Cherry Beach and 203 High Park routes will be suspended, the TTC says.
Service on the 509 Harbourfront will also be reduced on the weekend.
The public transit agency says the changes are due to decreased seasonal demand as fewer people travel to these destinations during the fall and winter.
