Route C would avoid Toronto Yard issues entirely by diverting trains via a new connecting track to the
Uxbridge Subdivision (GO Stouffville line) avoiding major capital works at the yard. As a result, the
capital costs associated with Route C are significantly lower than Routes A and B. One drawback
associated with Route C is that it bypasses two proposed stations on the western portion of the line at
Steeles Avenue and in Agincourt near Brimley Road. The new greenfield connection track, shown in
Exhibit 8-6, would depart the Havelock Subdivision just west of the 28th Sideline south of the 8th
Concession (Mile 170). From there, it would travel westward in a new right-of-way north of Markham for
4.91 miles to connect with connect to GO’s Uxbridge Subdivision at Mile 44.97, located just north of the
Major MacKenzie Drive crossing. The land along the proposed connection track is currently in
agricultural use.
Once on the Uxbridge Subdivision, under the Union Station option trains would parallel the GO
Stouffville line service using existing tracks south to the connection with CN’s Kingston Subdivision
(GO’s Lakeshore East line) at the Scarborough GO Station. From that point, trains would travel west
along the Kingston Subdivision using existing tracks to the Union Station Rail Corridor.
