With the constant changes in route diversions for various construction projects, water and sewer repairs and overhead reconstruction, the previous Fall 2025 edition was getting cluttered and unwieldy. This version consolidates the current and planned work for late fall and early winter 2025-26.
Updated December 21, 2025 at 8:45am
Current diversions:
- Until Spring 2026:
- 501 Queen cars divert both ways via Broadview, Dundas and Parliament.
- 503 Kingston Road buses divert both ways from River via Queen and Parliament.
- 504 King cars terminate at Distillery Loop.
- 504D King buses operate from Broadview Station to King & Parliament
- Ongoing:
- 501 Queen cars divert both ways via Church, Richmond/Adelaide and York.
Queen Street West of Broadview
Three projects are planned for Queen Street between Broadview and Davies Street east of the Don River.
- Fall 2025: Emergency sewer repairs starting November 27.
- Winter 2026: Watermain replacement starting January 2026.
- Spring 2026: Track replacement
Several routes are affected:
- 501/301 Queen streetcars will divert both ways via Broadview, Dundas and Parliament during both phases of the project. This diversion began on November 22.
- 503 Kingston Road will continue to operate with buses between Bingham Loop and York Street.
- During phase one, buses will operate via Queen and Parliament both ways to serve stops missed by the 501 Queen diversion. The diversion began on November 16.
- During phase two (track reconstruction, Spring 2026), westbound buses will divert via Broadview, Dundas and River.
- 504/304 King streetcars will operate to Distillery Loop.
- 504/301B replacement buses will operate between Broadview Station and King & Parliament.
With the delay to watermain reconstruction until January 2026, it is not yet clear whether the April 2026 date for restoration of normal streetcar service will actually be achieved.

I thought this was going to be a comedy piece! You could do that you know. Throw in a LOT of humour and say Where Is My Streetcar?!! And then make some sill answers! Perhaps as a holiday theme? Not wait til April Fools. I like the title. I want more!!!!!

Dec. 2 (11pm) to Dec 5 (4am): 506 Carton cars divert between Bathurst and Lansdowne via Dundas.
That means cars travelling East will be on Dundas until Bathurst then go north on Bathurst then turn east on College, only to turn south on Spadina and then continue east on Dundas until Bay and then turn north on Bay and East on College.
I mean why bother going on College only between Bathurst and Spadina… won’t it be better to just go straight on Dundas from Landsdowne until Bay ? Wouldn’t it be much faster? And how frustrating it would be for riders? Like who makes these decisions?
Steve: It’s also the combined effect of multiple overlapping diversions plus a protest at Yonge/Dundas. Carlton cars were running straight along Dundas from Spadina earlier, and as of 10pm they are back on Dundas.
Ps: Steve it was so great to meet you in person at the Streetcar event organized by TtcRiders!
Steve: Many thanks!

An interesting site that could provide answers 🙂
BlogTO background article
Thanks for the insights.
Steve: Yes, a very interesting site. The stats showing that “disorderly patrons” are the top cause of delay is interesting, along with other on-board issues such as ill patrons. In the recommendations, PSDs are proposed for a few major stations, but they will not address a large proportion of the total delays. Attention to issues such as patrons in distress on board and track fires are also important. Some of the track fires arise from debris thrown or blown onto the tracks, and that’s another rationale for PSDs, but this is not the only cause. Now that surface delay stats have more granularity, I am planning to work through them too once the full year 2025 is available.

506 operator today announced that the diversion would continue until 20 December. First I’ve heard a specific date.
Steve: Yes, the change back is in the Dec service changes which I have not published yet to avoid overlap with the Finch opening. In theory, they could restore service sooner if the overhead work is finished.
