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

From late Friday, April 11 until early Monday, April 14, the contractors are relocating the tracks in the rail corridor near the future Gerrard and Riverside / Leslieville stations as part of the project to build the new subway. They’re shifting the tracks from the east to the west side of the corridor between Jones Avenue and Jimmie Simpson Park. They already relocated one set of tracks during the weekend of Friday, March 21 until Monday, March 24.

GO Transit is cancelling train service along the 09 Lakeshore East line west of Danforth GO Station and along the entire 71 Stouffville line this weekend to accommodate the work.

Crews work 24 hours a day to:

• relocate barriers;
• cut and move rail tracks; and
• “surface” (compact), excavate, and back-fill ballast (the crushed stone that supports the tracks.)

They can’t complete these tasks while trains are operating and they must work overnight to make sure they have relocated the tracks in time to resume train service Monday morning.

Expect noise and vibration from construction equipment, including excavators, rail-cutting saws, spike pullers, track surfacing equipment, rollers, loaders, dump trucks, and hand tools. Expect to see site lighting at night.

The contractors will schedule disruptive activities, including surfacing during the daytime, wherever possible. They’ll use noise barriers and coverings to reduce disruption. And, they’ll direct site lighting away from residences.

Trucks enter and exit the work zone at access points on Eastern or Pape avenues.

This weekend, crews are also excavating at the bridge over Dundas Street East and removing graffiti from the noise barrier near Galt Avenue.
