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 buses replace trains between Stratford or Kitchener and Mount Pleasant GO stations.

GO trains operate hourly between Mount Pleasant and Mount Dennis GO stations. GO is not providing bus or train service between Mount Dennis and Union Station.

And, some GO buses operate between Stratford or Kitchener and Highway 407 Bus Terminal.

Construction also impacts some late-night service Friday evening.

Friday, August 14

• The westbound train that usually starts its trip in Union at 9:34 p.m. ends in Georgetown GO Station at 10:35 p.m.
• The westbound train that usually starts in Union at 10:34 p.m. ends in Kitchener five minutes later than usually at 12:31 a.m.
• GO is cancelling the westbound train that usually starts in Union at 11:34 p.m.

Saturday, August 15
Sunday, August 16

If you’re travelling from Stratford or Kitchener GO stations, board regular GO buses along the 30 Waterloo / Brampton route GO buses between Kitchener and Bramalea GO stations to connect with trains or stay on the bus to Highway 407 Bus Terminal to connect to the TTC’s Line 1 Yonge - University subway to Union Station. (Note, however, that buses replace Line 1 service between Sheppard West and St Clair West stations this Saturday and Sunday.)

If you’re travelling from Guelph Central, Acton or Georgetown GO stations, board regular GO buses along the 31 Guelph / Georgetown / Toronto or 33 Guelph / Georgetown / North York routes to connect with trains in Mount Pleasant. Note that trains end their trips in Mount Dennis. If you’re travelling to Union Station, board a replacement bus to Highway 407 Bus Terminal and connect to the TTC’s Line 1 Yonge - University subway.

If you’re travelling from Bramalea to Union, board regular GO buses along the 47 Hamilton / Vaughan route to Highway 407 Bus Terminal and connect to the TTC’s Line 1 southward to Union Station.

If you’re travelling to Union Station from all other stations, board the train to Mount Dennis and:

• board TTC trains along Line 5 Eglinton to connect to the TTC’s Line 1 at Cedarvale Station and then travel southward to Union Station (55 minutes).

GO isn’t providing any service at Bloor GO station. If you are travelling from Bloor to Union:

• board TTC trains along Line 2 Bloor - Danforth to connect to TTC Line 1 at St. George station (11 minutes).

GO is adjusting some schedules for trains along the line Monday, August 17 and Tuesday, August 18, with all eastbound trains from Stratford or Kitchener GO starting their trips two minutes earlier than usually, and all westbound trains from Union ending in Kitchener or Stratford two minutes later.

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.

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

And, GO buses replace trains along the 65 Barrie line 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 Saturday, August 15 and Sunday, August 16. GO buses replace the trains.

• All replacement GO buses start and end their trips in Highway 407 Bus Terminal.
• During previous occasions when buses replaced trains along the line:

• GO buses along route 65G served Aurora, King City, Maple and Rutherford GO stations and Highway 407 terminal.
• GO buses along route 65H operated express between Aurora and Highway 407 terminal.
• GO buses along route 65J served passengers at all stops, including East Gwillimbury, Newmarket, Aurora, King City, Maple, Rutherford and Highway 407 terminal.
• GO buses along route 68F dropped off or picked up passengers at Barrie Bus Terminal, Allandale Waterfront GO Station, Barrie South GO Station and then operated express — without stopping — to Highway 407 terminal.

• GO buses along route 68G served passengers at all stops, including Barrie Bus Terminal, Allandale Waterfront, Barrie South, Bradford GO Station, East Gwillimbury GO Station, Newmarket GO Station, Aurora GO Station, King City GO Station, Maple GO Station, Rutherford GO Station and Highway 407 terminal.

• GO buses along route 68H operated northbound only and serve Aurora, Newmarket, East Gwillimbury and Bradford.

• Southbound passengers aboard regular buses along the 68 Barrie / Newmarket / Aurora route wishing to connect with buses along routes 65H and 65G had to wait 15 to 20 minutes in Aurora.

• Northbound passengers aboard regular buses along the 65 East Gwillimbury / Newmarket / Toronto route wishing to connect with buses along route 68 had to wait seven to 12 minutes in Aurora.

Note that GO bus schedules differ from regular train schedules due to longer travel times.

This Saturday and Sunday, no Barrie-line trains or buses operate to and from Downsview Park GO Station. Board or exit TTC subway trains along Line 1 Yonge - University at Highway 407 Station to travel to and from Downsview Park or Union Station. Note, however, that buses replace subway trains along Line 1 between Sheppard West and St Clair West stations this weekend.

GO will further adjust service along the line Monday, August 17 and from Tuesday, August 18 until Thursday, August 20 due to residual effects of this weekend’s construction. Regular service resumes Friday, August 21.

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.

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

On the other hand, passengers travelling aboard trains along the 01 Lakeshore West and 71 Stouffville lines can expect extra service to help passengers travel to and from the Honda Indy in Markham.

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”).

The City of Markham is hosting the Ontario Honda Dealers Indy for the first time from Friday, August 14 until Sunday, August 16. The new venue for the event is the area around Unionville GO Station, significantly impacting GO Transit and York Region Transit services.

To accommodate event organizers while they build the race track, the Region of York is closing

• Kennedy Road [Regional Road 3] between Unionville Gate / South Unionville Avenue and YMCA Boulevard / Helen Avenue

from 9 p.m. Wednesday, August 12 until 6 a.m. Monday, August 17.

During and after the event, while the race team tears down the event infrastructure, the Region is also closing

• Kennedy between north of Duffield Drive and Unionville / South Unionville

from 9 p.m. Wednesday, August 12 until 6 a.m. Monday, August 17.

Before, during and after the event, the City is closing

• Enterprise Boulevard between Main Street Unionville and east of Andre de Grasse Street and

As preparations continue for the race, GO Transit passengers can expect impacts to parking, station access and bus service at Unionville GO Station, including a temporary full station access closure starting 8 p.m. Wednesday, August 12.

York Region Transit has already started detouring some of its buses to accommodate event preparations. It will detour buses along more routes, starting August 12.

The TTC is closing Line 1 Yonge - University subway between Lawrence West and St George stations earlier than usually Monday, August 10 until Thursday, August 13. Line 1 subway trains operate only between Vaughan Metropolitan Centre and Lawrence West stations and between Finch and St George stations after 11:59 p.m. those evenings.

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

(Or, consider a shuttle-bus alternative.)

Most stations on this section of Line 1 remain open, so you can pay fares, load PRESTO fare cards, buy PRESTO tickets and connect to TTC buses, streetcars or Line 2 Bloor - Danforth and Line 5 Eglinton trains. However, Glencairn and Dupont stations are closed. Note that the TTC is also closing the Heath Street West access to and from St Clair West Station and the Kendal Avenue access to and from Spadina Station after 11:59 p.m.

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

The TTC is closing this part of Line 1 at least twice more during August:

• Friday, August 14 — Sheppard West to St Clair West — close early — track work.
• Saturday, August 15 and Sunday, August 16 — Sheppard West to St Clair West — track work.

According to a TTC news release, “While the TTC does most subway maintenance after service each night, it continues to require weekend and early weeknight closures to complete critical infrastructure and state-of-good-repair work.”

GO’s route 18 is one of the system’s oldest bus routes, launched in September 1970 to connect the west end of the Lakeshore GO Train to Hamilton. Now that train the line has been extended to Hamilton, and the route 11 has been launched extending service to Brock University, the route 18 has become much less frequent, though it still serves to connect some Aldershot-bound GO trains to the Hamilton GO Centre and vice versa.

But that’s during the day. Late at night, or early in the morning, branches of the 18 run the full Lakeshore West line, providing a nominal owl service for the western half of GO Transit’s busiest train line. On the morning of Sunday, June 7, 2026, Transit Toronto editor James Bow woke up really early to head to West Harbour GO Station to ride one of the few 18J branches, serving Hamilton GO Centre, and most of the stations on the Lakeshore West train line. This timelapse video is the result. Check it out, and enjoy the backing music by Luke Holizna.

This Saturday, August 8 and Sunday, August 9, trains start trips in Durham College Oshawa GO Station two minutes earlier than usually.

Metrolinx continues building the Ontario Line subway between Exhibition Place / Ontario Place and the area near the former Ontario Science Centre, through downtown Toronto.

VIA/Amtrak’s Toronto-Niagara Falls “Maple Leaf” run is typically a routine morning trip. However, back in January, the Oakville subdivision was closed due to work required to expand the Lakeshore West GO Train. This forced the Maple Leaf to detour onto the Weston subdivision via Brampton and Georgetown before moving onto CN’s Halton subdivision to get to Aldershot.

Riders may not have appreciated their train going out of its way that morning, but railfans didn’t mind. Indeed, Richard YS was on hand to film his ride to Niagara Falls while on tracks that don’t typically see passenger trains. So, be sure to check out some rare scenery filmed during one of the snowiest days in Toronto’s history.

The TTC is closing Line 1 Yonge - University subway between Lawrence West and St George stations earlier than usually Wednesday, August 5 until Friday, August 7. Line 1 subway trains operate only between Vaughan Metropolitan Centre and Lawrence West stations and between Finch and St George stations after 1 a.m. those mornings. Regular service resumes about 6 a.m.

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