Metrolinx continues to upgrade the Stouffville rail corridor as part of the GO Expansion Program.

GO Transit is replacing trains with buses along the 71 Stouffville line after 11:30 p.m. Friday, July 26 and all day Saturday, July 27 and Sunday, July 28 to accommodate Metrolinx construction along the line. GO buses replace trains to travel to and from all stations along the line except Milliken, Agincourt and Kennedy GO stations.

GO buses operate along two branches:

• the 71E branch between Mount Joy GO Station and Union Station Bus Terminal, stopping at Markham, Centennial and Unionville GO stations; and
• the 71G branch between Old Elm GO Station and Union terminal, stopping at Stouffville, Mount Joy, Markham, Centennial and Unionville GO stations.

All buses operate express — without stopping — between Unionville and Union.

Board TTC trains and buses to travel to and from Milliken, Agincourt and Kennedy GO stations. York Region Transit buses also drop off or pick up passengers near Milliken.

Metrolinx contractors are building and maintaining tracks on the Stouffville corridor to make sure that trains operate safely and reliably. They are also focussing on updating key infrastructure for the Stouffville GO Expansion. They can only complete this work when trains aren’t operating.

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