The May schedules will bring many changes across the TTC network including:
- Streetcar network changes due to construction projects
- Route reorganizations in Downsview and Scarborough
- Many service reductions due to reduced pandemic-era riding
- Some service improvements to address crowding
Updated April 10, 2021 at 9:35 pm: References to “117 York University Heights” in the spreadsheet of detailed changes have been corrected to route “107”.
Streetcar Changes
Construction continues at the King-Queen-Queensway-Roncesvalles intersection. Phase 1 now underway is planned to run through August 2021. In Phase 2, work will shift to other parts of the intersection. The full project is planned to run through late 2021.
The only schedule change in May for this project is to give the Roncesvalles 504G shuttle additional running time.
The central-west Queen reconstruction includes conversion of overhead west from Parliament Street for pantograph operation as well as track replacement from University to Fennings (west of Dufferin). The 501 Queen streetcar service will divert via Parliament to King and will loop at Spadina via Charlotte Street. The 501L/P Queen bus service will be extended to Broadview Avenue.
The 503 Kingston Road service which also loops at Spadina & King will be adjusted so that headways and service blend with the 501 Queen service.
Water main reconstruction on Broadview between Danforth and Gerrard will require a bus shuttle until late in 2021. A 504D King shuttle will operate from Broadview Station to Front & Parliament via King. This will replace both the 504 King and 505 Dundas streetcar service north of Gerrard.
All 504 King service will run between Dufferin and Distillery Loops. Service west of Dufferin will continue to be provided by the 504Q shuttle between Shaw and Triller. Service east of Parliament will be provided by the 504D shuttle.
All 505 Dundas service will terminate at Broadview looping via Parliament and Gerrard.
Reconstruction of the overhead for pantographs on the east end of 506 Carlton as well as construction work at Main Station will be complete, and streetcar service will resume over the full route from Main Station to High Park Loop.
Weekday service on 510 Spadina will all terminate at Queens Quay Loop. Riders bound for Union Station will have to transfer to 509 Harbourfront. Weekend and overnight 310 Spadina service is unchanged.
Streetcars from 512 St. Clair running out of service via Bathurst southbound will no longer loop through Bathurst Station to avoid blocking the road and sidewalk when the platform is occupied by a 511 Bathurst car. 512 cars entering service will continue to run through the loop northbound.
The resulting streetcar network is shown in the map below.

Service Reorganizations
Two service reorganizations will occur in May.
In Scarborough, the 116 Morningside service will be consolidated so that all trips operate to Finch. The branch to Conlins Road will now be served by an extension of the 905 Eglinton East Express route.
In Downsview, the 107 St. Regis and 117 Alness-Chesswood routes will be combined as one route 107 York University Heights as shown in the map below.
Service details are in the spreadsheet at the end of the article.

Routes with revised schedules for reliability
The effect of reliability changes varies from route to route. Usually, the change involves adding running time without adding buses so that scheduled service becomes less frequent. In some cases, running times are trimmed to reflect changing traffic conditions such as the wind-up of construction projects

- 26 Dupont
- 29 Dufferin
- 32 Eglinton West
