The TTC will implement two route changes in July to address, in part, problems with service reliability on construction diversions.
Updated June 30, 2023: The location of Salsa on St. Clair has been corrected.
Updated July 1, 2023: The 506 Carlton cutback to Queen and Broadview has been added.
503 Kingston Road / 505 Dundas
Effective Tuesday, July 4, 2023 (July 3 is a holiday), service on Kingston Road to Bingham Loop (Victoria Park) will be revised on weekdays and Saturdays from 6am to 8pm, Sundays from 8am to 8pm:
- 505 Dundas cars will turn back at Woodbine Loop in stead of running through to Bingham.
- 503 Kingston Road buses will operate between Bingham Loop and York Street via King. Because these are “extras”, not scheduled buses, they will not appear on trip prediction apps.
After 8pm on all days, the 505 Dundas car will run through to Bingham Loop as it does now.
This change should relieve problems with tight running times that caused many short turns on 505 Dundas and wide gaps both on Kingston Road and on Dundas west of Lansdowne. (I will publish an analysis of 505 Dundas headways and reliability in early July.)


Effective Sunday, July 30, 2023, the 503 Kingston Road bus will operate between 6am and 1am (starting at 8am on Sundays) over its Bingham to York route.
Streetcars are expected to return in the fall, likely on Thanksgiving weekend. It is not yet clear whether the 503 streetcar will permanently replace the evening and weekend service formerly provided by the 22A Coxwell bus.
506 Carlton (Added July 1, 2023)
The 506 Carlton streetcar service will be cut back in the east end to Broadview rather than running east to Woodbine Loop. This will correct a problem with inadequate running time that caused many streetcars to short turn without getting to Woodbine Loop anyhow.
The map below shows the 506C bus diversion via Greenwood and Danforth around track construction at Coxwell and Lower Gerrard. This configuration will be in effect until mid-July when buses can again operate via Gerrard and Coxwell without diverting.

512 St. Clair
Effective Wednesday, July 5, 2023, the 512 St. Clair car will resume operation west to Gunns Loop. Construction at the GO Barrie corridor bridge west of Caledonia has been delayed allowing through service until August. The date when turnbacks at Lansdowne (Earlscourt Loop) will resume is not specified in the TTC announcement.
On the weekend of July 8-9, 2023, streetcar service will be suspended on at least part of the route (TBA) for the Salsa on St. Clair festival between Oakwood and St. Clair West Station.
Service on the temporarily extended 47 Lansdowne bus on St. Clair has been quite erratic. (Stay tuned for an analysis of this operation in coming days.)
