The TTC is closing Line 1 Yonge - University subway between Sheppard - Yonge and St Clair stations earlier than usually, Tuesday September 14 until Friday, September 18. Line 1 trains operate only between Vaughan Metropolitan Centre and College stations and between Finch and St Clair stations after 11:59 p.m. those days.

Shuttle buses partially replace subway service. The buses drop off or pick up passengers at stops near each station on the closed section of the line. TTC staff are available in each to station to direct you to the shuttle-bus boarding and offloading locations.

(Or, consider a shuttle-bus alternative.)

Most stations on the closed section of Line 1 remain open so you can pay fares, buy or load a PRESTO card or PRESTO ticket and connect to TTC buses and streetcars and Line 2 Bloor - Danforth trains. However Summerhill and Rosedale stations are closed. Note also that the TTC is also closing the Dundonald Street access to and from Wellesley Station after 11:59 p.m.

While this section of Line 1 is closed, TTC crews are maintaining the tracks.

According to a TTC news release, “While most subway maintenance is completed overnight when the system is closed, some larger projects require early nightly and weekend closures to allow crews safe and uninterrupted access to complete critical infrastructure improvements.”

The TTC is closing this section of Line 1 at least twice more during September:

• Saturday, September 19 and Sunday, September 20 — St Clair to College — track work.
• Monday, September 21 until Friday, September 25 — St Clair to College — close early — track work.

The TTC is advising passengers that from 11 p.m. Monday, September 14 until 4 a.m. Tuesday, September 15 and continuing overnight nightly, it’s detouring streetcars along these routes, due to “streetcar infrastructure work:”

• 310 Spadina overnight; and
• 510 Spadina.

(The transit agency hasn’t specified the exact site where its crews are working but it is somewhere on Spadina Avenue or Spadina Crescent north of Adelaide Street West.)

Shuttle buses replace the cars north of Adelaide West.

Streetcar infrastructure work on Spadina Avenue and the resulting TTC detours continue until September 17 (4 a.m.)

The TTC is advising passengers that it’s detouring streetcars from 11 p.m. Monday, September 14 until 3 a.m. Tuesday, September 15 due to “streetcar infrastructure work,” probably at or near

• the intersection of Queen Street East with Leslie Street.

Specifically, it’s detouring streetcars along these routes:

• 301 Queen overnight; and
• 501 Queen.

Shuttle buses replace the cars between Coxwell and Broadview avenues.

The TTC is delaying the start of service along Line 2 Bloor - Danforth subway between Broadview and St George stations this Sunday, September 13. All Line 2 trains operate only between Kennedy and Broadview stations and between Kipling and St George stations before 11 a.m. that day.

Shuttle buses partially replace subway service between the two stations, stopping on the street near stations on the closed section of the line.

(Or, consider a shuttle-bus alternative.)

Most stations on the closed section of Line 2 remain open so you can pay fares, buy or load a PRESTO card, PRESTO ticket or connect with buses, streetcars and Line 1 Yonge - University subway trains. However, Sherbourne and Bay stations are closed before 11 a.m. Note, also that the TTC is also closing the Yonge Street access to Line 2 at Bloor - Yonge Station

Although shuttle buses are accessible, extra Wheel-Trans service is also available between Broadview and St George stations. Ask staff in each station for information about Wheel-Trans service.

While this section of Line 2 is closed, City of Toronto contractors work under the Prince Edward Viaduct to replace beams.

According to a TTC news release, “While most subway maintenance is completed overnight when the system is closed, some larger projects require early nightly and weekend closures to allow crews safe and uninterrupted access to complete critical infrastructure improvements.”

Metrolinx confirms that it’s working on the GO Expansion Program this weekend and that work impacts UP Express service. But it also says it’s preparing for construction of the future Stockyards and Woodbine stations. The projects also require GO “to temporarily suspend service” along parts of the Kitchener line and the UP Express line “so that construction can be performed safely.”

(The future Stockyards GO Station was formerly known as St. Clair - Old Weston Road GO Station.)

As we explained, GO is revising service along the 31 Kitchener line due to the construction this weekend.

And, GO is cancelling train along the 65 Barrie line south of Downsview Park GO Station this weekend.

Metrolinx continues upgrading the 31 Kitchener line as part of the GO Expansion Program.

This Saturday, August 15 and Sunday, August 16, Metrolinx construction affects service along GO Transit’s 31 Kitchener line.

GO is also adjusting some schedules for trains along the line Monday, September 14 until Friday, September 18 due to the residual effects of this weekend’s construction.

Metrolinx confirms that is working on the GO Expansion Program this weekend. But it also says it’s preparing for construction of the future Stockyards and Woodbine stations. The projects require it “to temporarily suspend service along the Kitchener line so that construction can be performed safely.”

(The future Stockyards GO Station was formerly known as St. Clair - Old Weston Road GO Station.)

Crews are also conducting foundational work for a future second track and improving the corridor by installing culverts, utilities and signal work.

Construction on the Kitchener line also affects UP Express service this weekend.

And, GO is cancelling train service along the 65 Barrie line south of Downsview Park GO Station this weekend.

Metrolinx and GO plan to accommodate more passengers and increase service along the Kitchener line, as part of their GO Expansion Program (formerly “regional express rail”).

Metrolinx and its contractors continue upgrading GO Transit’s Barrie line as part of the GO Expansion Program.

Due to GO Expansion construction this weekend, GO is cancelling train service along the 65 Barrie line between Downsview Park GO Station and Union Station Saturday, August 15 and Sunday, August 16. Trains operate only between Allandale Waterfront and Dowsview Park GO stations.

However, GO has also cancelled most regular weekend trains and replaced them with buses “until further notice.” Buses operate between Allandale Waterfront and Highway 407 Bus Terminal so that you can connect to TTC subway trains along Line 1 Yonge - University southbound service to Union.

GO will further adjust service along the line Monday, September 14 and Tuesday, September 15. Regular service resumes Wednesday, September 16.

Metrolinx is expanding key areas of the Barrie-Line corridor to support improving service by adding a second track in the future. It’s also significantly upgrading:

• Maple GO Station;
• King City GO Station; and
• Aurora GO Station.

This weekend, crews are also maintaining the tracks with a rail-milling machine. Rail milling removes surface defects and restores the rail head profile, by improving wheel rail contact and extending rail life. They start working near Steeles Avenue West and proceed in stages southward along the Barrie Line to Brock Avenue, with crews occupying one work area at a time.

They’re also working at the future Junction Triangle GO Station and completing essential maintenance in the corridor.

(The future Junction Triangle GO Station was formerly known as Bloor - Lansdowne GO Station.)

GO is also revising service along the 31 Kitchener line this weekend. And, GO buses replace UP Express trains.

Metrolinx and GO plan to accommodate more passengers and increase service along the Barrie line, as part of their GO Expansion Program (formerly “regional express rail”).

For 95 years, 504 King grew into one of the longest-serving unchanged routes on the TTC network. Then, on October 7, 2018, the line broke into two branches, one running from Broadview Station to Dufferin Gate, the other from Dundas West Station to Distillery Loop. A year earlier, the City of Toronto gave streetcars priority on King Street between Bathurst and Jarvis, banning through-traffic at most intersections except for taxis, bicycles, and streetcars, and extending platforms into the street.

These changes made the line more reliable and, travelling as it did through rising high-density residential neighbourhoods and the destinations of the Entertainment and Financial districts, this propelled 504 King to becoming the most heavily used surface route on the TTC network, carrying over 80,000 passengers during an average weekday.

Nearly ten years later, King cars continue to trundle through Toronto’s core, offering frequent service and carrying thousands of passengers daily, but what of the changes that helped 504 King become the King of the TTC’s surface network? Could they not use a little love?

Transit Toronto Editor James Bow paid a visit to the 504A King line on Sunday, June 21, 2026, and filmed footage for this timelapse video. He followed up with a visit to the 504B branch on July 6, 2026. Follow along in the streetcar’s wake as we see King Street, Broadview Avenue and Roncesvalles Avenue be the hub of activity that they are, and think of what 504 King could be if the measures to improve it back in 2017 are spruced up and made permanent.

The Toronto International Film Festival in downtown Toronto tops the long list of special events affecting transit services this weekend — from Thursday, September 4 until Wednesday, September 10.

And, the annual Supercrawl arts and music festival disrupts many transit services in downtown Hamilton.

Events take place in Aurora, Brampton, the Etobicoke area of Toronto, the Malton area of Mississauga, Milton, the Port Credit area of Mississauga and downtown Toronto.

Starting 5 a.m. Thursday, September 4, the City of Toronto is closing

• King Street West between Spadina and University avenues

to accommodate various events for the Toronto International Film Festival.

The TTC is detouring streetcars along these routes, while the street is closed:
