The City of Toronto has announced that work at King & Dufferin is finished and the intersection will reopen to traffic on Wednesday, October 29 after 7pm.
Regular service will be restored on 29/929/329 Dufferin, and the 503 Kingston Road bus will be extended west from Joe Shuster Way (east of Dufferin) to Roncesvalles at 5am on Thursday, October 30.
TTC will test the new track and overhead during the week of November 3 and will restore 504 King and 508 Lake Shore services from their current Shaw/Queen diversion when the intersection is cleared for streetcar operation.
Meanwhile, the TTC CEO’s Report notes that six minute or better service will come to 505 Dundas and 511 Bathurst from 7am-7pm 7 days/week starting November 16.
There are many diversions coming up in the Fall for streetcar routes. Information on these appears in various places on the TTC site, mainly but not exclusively under Service Advisories. As an aid to riders, this article consolidates the available information in one place.
Updated November 28, 2025
***** This article is only for archival purposes. It has been replaced by a new one picking up from mid-November 2025. *****
Major events pending and in progress include:
Construction on Queen between Davies (just east of the Don Bridge) and Broadview.
Reconstruction of the intersection of College and McCaul, and of overhead in the vicinity.
Reconstruction of track and overhead at and near Parliament and Carlton.
Other short term diversions will last only overnight or for a weekend.
Many of these are complicated by the ongoing Ontario Line work at Queen & Yonge forcing some diversions to be more complex than they might be otherwise.
This article will be updated when changes are announced.
November 21: The 501 diversion via Broadview, Dundas and Parliament around water main and track work west of Broadview will begin on November 22.
November 20: Equipment and material mobilization is underway on Queen west of Broadview.
November 17: The 506 diversion has been changed today to avoid the intersection of Church & Dundas where construction blocks the northeast corner. Maps have been added from the TTC’s site.
Effective November 16: The 503 Kingston Road bus will be cut back from Dufferin, and will now loop at York Street via Richmond and University.
November 15: Diversions announced for two projects on 506 Carlton at Parliament & Carlton, and on Gerrard east of Broadview.
November 9: King & Dufferin reopened for streetcar service. 503, 504, 508 will operate via their normal routes.
October 30: King & Dufferin reopens for general traffic and buses. Streetcars to return following track testing.
October 20: Water main reconstruction on Queen west of Broadview has been delayed until early November. 501 Queen streetcars will continue to operate on Queen Street until further notice.
October 13: 504 King is operating with streetcars today over its full route except for the King/Dufferin diversion.
October 9: Maps for 504 King and 506 Carlton diversions added.
October 8: Construction at Queen & Broadview will not start on October 12, and so some diversions will not be required immediately. Information for 501 Queen and 503 Kingston Road has been updated.
October 5: Nuit Blanch & Run For the Cure info moved to the archive section.
October 1: Diversions of 505/305 Dundas and 506/306 Carlton for Nuit Blance and for the Run For The Cure added for October 3/4/5.
September 23: The King/Dufferin start date has been changed to Sunday, September 28.
September 12: King/Dufferin start date pushed back to September 29 or later. The project will now extend to mid-November.
September 9: College/McCaul and Queen East details added.
August 26: King/Dufferin Project
The start date for this project has been changed to mid-September with the exact date to be confirmed. Although new schedules will be in place providing for diversions, service will continue to operate through on King Street until construction actually begins. This likely means that the project will extend further into October than the originally planned Thanksgiving weekend end date. The delay also means that the Tiff diversions will end before the King/Dufferin diversions begin.
Branch lettering for 504 King A/B corrected.
August 25: King/Dufferin Project
Information about Kingston Road night service added.
304 King and 329 Dufferin confirmed to be diverted on the same routes as the 504A and 29 daytime services.
The TTC is into the second round of its consultation for service changes and construction projects in 2026. There is a general page on the 2026 Network Plan and a Survey for feedback.
If you comment here, be sure to also complete the survey so that your feedback goes into the official record.
Updated August 14, 2025 at 1:20pm: This article was written based on information in the customer survey as it existed about 4:00 pm on August 13 when the link to it went live on the TTC site. This included a reference to a minimum 5 minute time saving for express buses which did not match the TTC’s own service standard. The survey now contains the correct information. Text in this article has been updated accordingly.
Updated August 22, 2025 at 2:40pm: The City of Toronto has confirmed that widening of the St. Clair underpass east of Keele Street will not be part of the Metrolinx/TTC project planned for 2026.
Public Pop-Ups
August 13: Pioneer Village Station near express route bus bays 7:30-9:30 a.m.
August 14: Kipling Station near express route bus bays 7:30-9:30 a.m.
August 18: Kennedy Station near express route bus bays (Platform A and B) 7:30-9:30 a.m.
August 19: Don Mills Station near express route bus bays 4-6 p.m.
August 20: Yonge and College 506 Carlton, Eastbound stop 4-6 p.m.
Note that almost all of these relate to the review of express bus services, and only one of the construction proposals (College/Carlton) is covered. More consultation in affected neighbourhoods is definitely required.
Starting after Labour Day in September, the TTC will rebuild the track at the King-Dufferin intersection. This work is expected to take about six weeks.
The project is left over from work on King West in 2024 when it could not be completed as planned due to supply problems. It was erroneously reported that the 2024 project finished “early” when in fact this was due to the scope change.
Transit services will be significantly changed in this area.
Source: City of Toronto Report at p. 5
Note that the diversions for King-Church construction are expected to end before King-Dufferin work begins, and transit services on the eastern part of King will be back to normal.
Route changes at King-Dufferin:
Routes diverting east of Roncesvalles via Queen and Shaw to King:
504A King streetcars from Distillery Loop to Dundas West Station
304 King night cars from Broadview Station to Dundas West Station
508 Lake Shore streetcars from Long Branch to Broadview Station
No service on King between Mowat and Roncesvalles
504B King streetcars will operate from Broadview Station diverting from King via Bathurst to Wolseley Loop (at Queen).
Kingston Road services:
503 Kingston Road converted to bus operation and cut back from Dufferin to loop via Mowat and Fraser.
303 Kingston Road night service suspended (it is not yet clear what will replace the 303 on Kingston Road)
Dufferin bus services:
29 Dufferin buses will divert via Queen, Shaw and King looping via Mowat and Fraser.
929 Dufferin Express buses will terminate at Queen looping via Queen, Gladstone and Peel.
No service on Dufferin south Queen nor through Exhibition Place to Princes’ Gate.
Parking and stopping provisions will change on Queen from Roncesvalles to Shaw, and on Shaw between Queen and King. Stopping will be prohibited on both sides of these streets seven days/week from 7:00 to 11:00am and 2:00 to 7:00pm.
Left turns will be banned from Shaw northbound at Queen and southbound at King. Left turns are now banned from King eastbound onto Shaw weekdays from 7:00 to 10:00am, and from 3:00 to 7:00pm. This will be extended to a ban from 7:00am to 7:00pm on all days.
Some existing parking spaces will be removed to make room for transit vehicles on Dufferin north of Queen, Peel, Mowat, Liberty, Fraser, and King. Details are in the report.
These changes will only last for the duration of the construction project.
The TTC plans to “conduct comprehensive targeted engagement to inform and educate customers, residents, local businesses, and other partners of the pending changes.” However, major changes are unlikely as this project is only two months away and temporary transit routes are already decided. The TTC does not yet have a page on its own site for this project.
This issue will be at Toronto & East York Community Council on July 8, 2025.
Two proposals before City Council attempt to deal with congestion issues downtown brought on by the King/Church water main and track reconstruction.
MM31.17 – Speeding Up Streetcars: Traffic Amendments on Adelaide Street, King Street and York Street – by Mayor Olivia Chow, seconded by Deputy Mayor Ausma Malik
This motion proposes the relocation of parking and loading zones from Adelaide Street to nearby streets to free up capacity on Adelaide.
Currently, the Financial District Business Improvement Area and their stakeholders use loading zones on the south side of Adelaide Street West, from Yonge Street to York Street, between 10:00 a.m. to 3:00 p.m., Monday to Friday. Based on the travel time data, streetcar operations are negatively impacted when the loading operations are in effect.
In consultation with the Toronto Transit Commission, Transportation Services and the Financial District have agreed that temporary loading zones will be established on the west side of York Street, between King Street West and Wellington Street, and on the north side of King Street West, between Yonge Street and York Street.
Delivery drivers will queue in the new loading zones, where Traffic Control Persons will marshal the delivery drivers into the loading bay only when it is clear. With the temporary loading zones in place, stopping will be prohibited on Adelaide Street West from 7:00 a.m. to 7:00 p.m., Monday to Sunday.
Mayor Chow proposed an amendment to her own motion authorizing payment “to deploy additional paid duty officers at seven locations near the King and Church worksite to manage traffic flow”.
MM31.18 – Re-Opening King Street for Business: Keeping Toronto’s Downtown Core and Canada’s Financial District Moving – by Councillor Brad Bradford, seconded by Councillor Stephen Holyday
This motion proposes the reopening of through traffic on King Street where streetcars are not operating during the construction diversion.
City Council direct the General Manager, Transportation Services, to make any necessary changes to reopen the portion of King Street between Spadina Avenue and Church Street to vehicular traffic for the duration of the King Street East and Church Street intersection closure, where streetcars are not currently in service.
Mayor Chow proposed an amendment limiting the reopened area to portions where “streetcars and buses” are not operating. This effectively neuters the motion because the only portion of King with no transit service now is east of Yonge Street.
The debate was mired by a combination of political rivalries, lack of familiarity with the affected area and transit services, and disinformation either through ignorance or misrepresentation.
The Mayor’s motion MM31.17 and amendment carried on a show of hands.
The Mayor’s proposed amendment to MM31.18 carried by 16-5. The motion as amended carried on a show of hands.
The debate was hampered by the absence of basic information such as a map and detailed information on items such as existing transit services, traffic pinch points and loading zone locations.
In support of his claim that King Street could be reopened, Councillor Bradford showed a photo looking west on King from Simcoe with the street completely devoid of traffic. The photo was taken at 6:30pm on Monday.
Monday is a very light day for office-bound traffic due to work-from-home patterns. This is also reflected in day-of-the-week travel time differences shown later in this article.
The theatre district (Roy Thomson Hall, Royal Alexandra and Princess of Wales Theatres, TIFF) are dark on Mondays, and there is little tourist traffic. There was no major event at the Rogers Centre.
Although an empty road can be found at times, the photo is deeply misleading, and Bradford should know better.
Among the most striking pieces of disinformation was the claim that replacement bus service carries far fewer riders than the streetcars did along the King Street corridor. When asked, staff gave riding figures of 24,000 on the King Street replacement bus, and 60,000 per day for the streetcars. These are all day values for the entire route, not for riding on the King Street transit corridor itself. At no point was there any discussion of the frequency (and hence capacity) of service. These numbers were cited by various Councillors to claim that transit priority was not needed on King because so many fewer people were riding there.
City staff should be chastised for failing to correct this point and for giving an answer that did not properly illuminate the comparison between service levels.
For the record, the scheduled service on the central portion of King Street with streetcars and buses is shown below. Note that there is substantially less scheduled capacity with the replacement bus service. Buses on King are quite crowded, and service is bunched and erratic.
It is quite likely that there are fewer riders on the buses than on the streetcars, although a major contributing factor will be the level of service provided by the TTC. From a capacity viewpoint, a service of 18 buses/hour with 50/bus (greater than the Service Standard level) would be 900 riders per hour past a point. The streetcar service would have a capacity more than double that level.
PM Peak Service
Streetcar Service (Apr/25)
Bus Service (June/25)
504A Distillery-Dundas West
10′ (6 cars/hour)
504B Broadview-Dundas West

504C Distillery-Bathurst

In the course of the debate, Mayor Chow noted that work at King & Church is progressing well and should be finished by August 8. This may allow the road to reopen, but resumption of streetcar service depends on the TTC finishing their work including reconstruction of streetcar overhead at that intersection and along King Street East.
The remainder of this article updates previously-published charts about streetcar travel times on Richmond and Adelaide Streets.
Updated June 24, 2025: The TTC has now standardized the 504 King and 503 Kingston Road diversions so that both routes (and associated night services) operate via Queen and Shaw Streets
The diversions for track reconstruction on King Street will change again on Sunday, June 22. The TTC has posted conflicting information both on its website and in its weekly update memo regarding construction and special events. I have asked TTC for clarification and will update this page if and when they reply.
In an email on June 19, the TTC announced:
From 6 a.m. on Sun., June 22, until 4 a.m. on Sat., Jul. 12, the 503/303 Kingston Road streetcars will divert to accommodate streetcar track work on King St. between Shaw St. and Spadina Ave. 503/303 Kingston Road streetcars will run along Queen St. between Shaw St. and Dufferin St. 504D King replacement buses will be extended to run from King St. and Bathurst St. to Dufferin Gate Loop.
Affected routes:
503/303 Kingston Road cars which now operate via Queen, Spadina and King to Dufferin Loop will change to run via Queen Street to Dufferin and then south to Dufferin Loop. This changed on June 24. See below.
504D shuttle buses (Broadview/Bathurst) will be extended west from Bathurst via Queen and Dufferin to Dufferin Loop. In fact the buses ran west via King, not Queen.
Here are the original TTC maps.
Source: TTC 503 and 504D Diversion Notices (No longer online)
It appears that whoever designed this change notice is unaware that the 503 does not now operate via Queen and Shaw, but in fact runs on King from Spadina westward.
Updated Monday, June 23 at 10:45pm: The erroneous map of the 504D diversion has been replaced on the TTC’s site. Here is the corrected map.
Updated Tuesday, June 24 at 5:00pm: The diversion of 503/303 and 504/304 services has now been standardized via Queen and Shaw Streets, and the notice/map also include the 504D bus extension west from King and Bathurst to Dufferin Loop.
511 Bathurst cars resume service to Exhibition Loop and will not operate east on King from Bathurst to Charlotte Loop at Spadina.
508 Lake Shore service is discontinued for the summer.
There is no reference to the existing 504 streetcar route which operates via Queen and Shaw to King, nor is there any explanation of why the 503 and 504D services cannot use the same route. (Corrected effective June 24.)
Here is the construction plan included in the June 22, 2025 service change memo clearly showing where the 503 car runs today, but this will not, in fact, be how the routes operate starting June 22.
Taking the TTC notices at face value, this means that service on parts of King will be affected in different ways:
From Spadina to Bathurst, only the 504C/D shuttle buses will operate and will, presumably, dodge around construction as they have been doing in recent weeks during track margin repairs along King Street.
From Bathurst to Shaw, there will be no transit service. This affects stops at Tecumseth, Niagara and Strachan. Updated: The 504D buses are supposed to run west on King from Bathurst to Dufferin, but few of them actually get beyond Bathurst.
From Shaw to Dufferin depends on the continued operation of 504 King cars. As of June 24, 503 Kingston Road cars were also running via Queen, Shaw and King.
This is a repetition of the classic TTC communications cock-ups of past years where diversions are poorly or inaccurately explained. They are supposed to be “doing diversions differently” this year, but this is not a sterling example.
Updated 4:50 pm June 20: There are separate pages on the TTC website describing the 503/504 diversions which make no mention at all of the change effective June 22. They refer to the summer suspension of the 508 Lake Shore, but assure riders there are no other changes:
Starting Monday, June 23, 508 Lake Shore streetcar service will be suspended until early September for seasonal service adjustments. There will be no changes to 503/303 Kingston Rd, 504/304 King streetcars or to 504/304 King replacement bus routing. [Source: TTC Streetcar service changes.]
As of Tuesday, June 24, the separate streetcar diversion pages for the King and Kingston Road services still make no mention of the changes west of Bathurst Street.
Effective Monday, June 2, 2025, the 504C/D and 304D shuttle buses will divert around the construction at King & Church via Yonge, Front/Wellington and Jarvis as shown in the map below. This affects only the shuttle buses, and the streetcar diversions via Richmond/Adelaide are not affected.
How this will work with already congested conditions south of King on Yonge and on Jarvis remains to be seen.
Source: TTC
The map below combines all of the diversions into one view of where King and related routes are diverting in and near downtown.
Not shown are:
501 Queen continues to divert via Church, Richmond/Adelaide and York.
509 Harbourfront which is temporarily replaced by a bus between Spadina and Exhibition Loop.
510 Spadina continues to operate from Spadina Station to Union Station.
511 Bathurst continues its split operation with streetcars running east on King to loop at Spadina and a shuttle bus replacement to the Exhibition due to construction at Bathurst & Lake Shore.
Updated May 16, 2025 at 3:50pm: The TTC has now published a map of the revised diversion routes.
In response to congestion problems for streetcars turning on and off of King and Queen Streets at Spadina, the TTC has modified the route of 504 King.
Instead of running west via Queen, Spadina and King, the 504 will now divert via Queen, Shaw and King. The 503 Kingston Road car will continue to operate via Spadina and King to Dufferin Loop.
The TTC has not yet updated the information on its King-Church diversion page as of 1:30pm May 16, but plans to do so. On-street signage will also be changed. The diversion map and information appear on several different pages, and it will be interesting to see if the TTC changes all of them.
Updated 3:50pm with revised diversion map for routes 504/304, 503/303 and 508. Not shown are routes 501 Queen and 511 Bathurst.
This reduces the peak streetcars/hour attempting to turn east-to-north at King and Spadina from 23 to 17, and west-to-south at Queen and Spadina from 13.5 to 7.5 (plus occasional 508 Lake Shore cars). Off-peak service is almost the same as peak service and so these numbers do not change much during those hours.
Numbers eastbound at King will be further reduced in late June when the 511 Bathurst cars, 6.5/hour, resume their normal route to Exhibition Loop, and 508 Lake Shore cars, 3/hour at peak, are suspended for the summer.
Updated: Now that the map has been published, it is clear that the 504C/D buses will continue to loop at Bathurst, and service on King from Bathurst to Shaw will only be provided by the 503 car.
Problems remain further east on the diversion with all of the 501 Queen, 503 Kingston Road, 504 King and 508 Lake Shore cars making turns to and from Church, Richmond, Adelaide and York, a total of about 23 per hour. There is also severe traffic congestion on Adelaide, but it is not clear how much of this is caused by queuing streetcars, and how much due to traffic volume and road capacity.
The option of using Victoria Street for the link between Queen and Richmond/Adelaide is not available because of Ontario Line construction, even though this would have separated the streetcar diversion from the busier Church Street.
Today was the first weekday of the King/Church construction diversions. I watch things evolve via NextBus through the morning peak, and then visited King/Spadina during the PM peak. A caveat: Mondays are light traffic days. There was no Gardiner backlog at all on Spadina. Later in the week will likely be more challenging.
During the AM peak, the service on 504 King and 503 Kingston Road did not load properly, and many vehicles were clumped together. This took quite a while to unscramble, and there were big service gaps. The 504 buses also ran in packs and huddled together at Wolseley Loop, at one point six of them representing about 20 minutes worth of service at the scheduled headway. The peak period did not encounter queueing frequently at points where streetcars turn because of many wide service gaps. When a bunch of cars arrived, they queued one by one awaiting their turn, but then the intersections would open up again even though in theory there should always have been transit service waiting.
In the PM peak at King/Spadina, the major sources of traffic were pedestrians, cyclists and transit in that order. I observed that the traffic signal cycle time was 110 seconds (1’50”). This means that there are 32.7 opportunities (3600/110) per hour for a turn to/from Spadina. The nature of the intersection is that only one streetcar can make the turn per cycle.
The combined scheduled service trying to make the EtoN turn per hour at King & Spadina in the PM peak is 23 streetcars.

Stir in 12 510 Spadinas straight through northbound on a 5′ headway. When there is a 510 (or any other car) serving the farside NB stop it blocks any car waiting to turn off of King. In a 45 minute visit, I saw this happen four times, and one car missed two turning opportunities because of closely-spaced Spadina cars blocking the stop.
Depending on arrival times and bunching, more vehicles can queue up here than there are cycles to accommodate them. This was under probably the best general traffic conditions we will see.
There were traffic wardens, but they left just before 5pm. The biggest problem was pedestrians blocking turning streetcars which do not have a protected turn phase EB on King. There is a WB advanced green because autos are forced to turn off King here, but there is no advanced green for eastbound streetcars.
The large volume of riders transferring from eastbound streetcars to buses adds to the already substantial pedestrian volumes at this intersection.
The Traffic Wardens did not reliably ensure that streetcars got “first dibs” on turning, and after they left, pedestrian interference became worse.
I boarded a 504 King eastbound at about 5:10. There was congested traffic over the route across to Church especially on Adelaide and it took over 15 minutes to get from York to Church. Some people complain about space “wasted” by bike lanes, but it was the left turn lane that was almost always empty. Some traffic used it to scoot around stopped streetcars!
The severe congestion can be seen in the TransSee maps of service for 504 King and 503 Kingston Road below. The tracking lines for the diversion area are almost horizontal for an extended period. Note that the problem is mainly eastbound (lines reading bottom to top).
Tracking data for routes 503 and 504, May 12, 2025, 4pm to 7pm. From TransSee.ca.
I rode a King car east from Spadina and it took a very long time to emerge from the diversion. The car went from 6 minutes early at King on Spadina to 11 minutes late at Queen and Church. Note the length of time spent approaching King and Spadina inching along the street about one carlength at a time. Other locations where the car crept along are also clear in the tracking data.
Tracking data for car 4634. Source TransSee.ca.
Among the problems enroute were:
Congestion on Queen thanks to stopped vehicles and construction in the curb lanes.
Autos infilling Adelaide Street eastbound leaving no room for a streetcar to merge from York Street onto Adelaide. We were eventually rescued by a Traffic Warden.
Extremely slow progress across Adelaide thanks to a traffic backlog from Church Street.
Extremely slow progress on Church Street thanks to a traffic backlog from Queen Street. My car actually fouled the Church/Adelaide intersection as it was unable to complete the EtoN turn in more than one traffic signal cycle.
Ridership on the car was very light and most people got off when the car turned off King onto Spadina. They transferred to the King shuttle buses which were running irregularly and often bunched. These buses were also trapped in the traffic queue eastbound to Spadina of streetcars waiting to turn. (In the chart below, the size of the dot represents the degree of crowding on the vehicle.

For those who want to watch the wandering streetcars and buses on NextBus, here is a link. This will open a combined display of routes 501, 503, 504, 510 and 511. The map can be scaled to zoom in to the area of interest. Displays of operating charts on transsee.ca are free for TTC streetcar routes.
Over coming days I will keep an eye on service performance over the diversion, and once a few weeks’ data have accumulated will delve into the details.
The TTC now has a web page with details of the changes for the first phase of the construction and diversions. This includes a map showing the diversions to west of Bathurst rather than just downtown. I have added this in the body of the article.
May 5, 2025 at 1:40pm:
Information about the 304 King and 303 Kingston Road night services has been added.
May 5, 2025 at 1:55pm:
The TTC has confirmed that overhead upgrades on King Street East and on Sumach/River will be completed before the King/Church track work end, and streetcar service will resume in September.
May 5, 2025 at 4:30pm:
I asked the City if it thought the intersections used by diverting streetcars and buses could handle the volume of traffic. They replied, but didn’t add much. See the end of the article for the exchange.
Major changes are coming to downtown streetcar routes on May 11 with the next schedule change. This will accommodate a combination of water main replacement, track reconstruction and streetcar overhead upgrades mainly at King and Church. Work is expected to require diversions until the October schedule change on Thanksgiving weekend.Streetcar service is expected to return with the September schedule change on Labour Day weekend.
The effects of work an King and Church have been known for some time through the Annual Service Plan and through a City report on the project. (The original report and recommendations were amended at the recent Council meeting to lessen the effect of various proposed lane closures.) Service levels have been published via the electronic version of schedules used by trip planning apps. The information about vehicles/hour at various locations is taken from those schedules.
(As an aside, the TTC website has still not been updated to include the 2025 Service Plan even though it was approved by the Board in January.)
With the concentration of transit service through various intersections, and the added complexity that most vehicles will make turns at these locations, there simply will not be enough capacity even under ideal conditions. It is no secret that “ideal” is a word rarely appropriate for transit operations downtown thanks to the lack of robust traffic management and real transit priority.
In past years, the diversion of services from King Street around the TIFF street fair created problems for transit travel times and reliability, but this lasted for a brief period. The planned diversions for King/Church will last through the summer.
Many of the water mains in the “old” city have been in service for over a century. Other parts of King Street have seen renewal, occasionally on an emergency basis following a break and sink hole.
The special trackwork at the King/Church intersection has been in bad shape for some time, and was overdue for replacement. Previous reconstructions were in 1983 and 2003. Other competing construction projects got in the way, and the track conditions have worsened year by year. There are many patches, and a well-deserved slow order unlike the standing practice even at freshly rebuilt junctions.
This intersection is also old enough that it predates the era of panel track construction where pre-welded sections are trucked in and assembled on site. This replaced the older style of tracks assembled piece-by-piece and often not welded robustly if at all. TTC has not yet been through its entire inventory of “old” track given the 20-30 year cycle depending on the level of service, wear, and disintegration at intersections.
Other work planned for this period of suspended streetcar service is the reconstruction of overhead on King and on the Distillery branch for pantograph-only operation.
Closing King & Church for an extended period concurrently with the Ontario Line construction at Queen & Yonge will add to the traffic snarls downtown. The City talks about using Traffic Agents to manage key intersections, but whether they provide enough people at enough places at enough times remains to be seen.
Routes Diverting off of King Street
Three routes are affected: 504 King, 503 Kingston Road and 508 Lake Shore.
The 504 King service will be broken into three sections:
A 504 streetcar service between Broadview to Dundas West Stations operating via the same route as 501 Queen between the Don Bridge and Spadina.
A 504C bus shuttle from Wolseley Loop south on Bathurst and east on King terminating at Broadview & Gerrard.
A 504D bus shuttle from Wolseley Loop south on Bathurst, east on King and south on Sumach to Front & Cherry. Buses will loop via [to be announced] and will not serve Distillery Loop.
The 503 Kingston Road service will be changed so that its western terminus shifts from York Street to Dufferin Loop. Cars will follow the same route as the 504 King via Queen from the Don Bridge to Spadina, then shift south onto King to follow the pre-diversion 504B route to Dufferin.
508 Lake Shore cars will follow the same route as 504 King.
Night Service Changes
The 304 King night car will operate every 20 minutes over the same route as the daytime 504 service diverting via Queen and Spadina.
A 304D night bus will run every half-hour over the same route as the 504D bus from Wolseley Loop to Broadview & Gerrard.
The 303 Kingston Road night car will operate every 20 minutes over the same diversion route as the 304 King night car, and will operate as it does now to Sunnyside.
The maps below are from the City Report about this project originally published in February. An updated map for the first phase has been added later in the article.
For part of the construction period, King/Church will be impassible even to the replacement bus service and it will divert south to Wellington and Front.
These maps do not tell the whole story because another set of construction diversions will overlap the King/Church changes until the next schedule change in late June.
Although water main work at Bathurst/Fleet/Lakeshore is now complete, track work continues there and on Bathurst Street further north. 511 Bathurst streetcars will continue to divert east via King to Spadina looping via Adelaide and Charlotte. The 511B shuttle bus will be shortened from Wolseley Loop at Queen to an on-street loop via King, Portland and Richmond to Bathurst Street.
509 shuttle buses continue operating between Exhibition Loop and Queens Quay Loop at Spadina. 510 streetcars continue operating to Union Station.
The combined effect of the diversions will be greater than during the total meltdown of King service in 2024 when all cars diverted north via Church to Queen because volumes of other routes (510 Spadina, 511 Bathurst and 501 Queen) will be added to the King services, and more intersections will be affected over a wider area.
