Man suffers serious injuries after being trapped at Toronto construction site
A man has been rushed to hospital with serious injuries after becoming trapped at a construction site in Toronto.
Power Downtown Toronto – 2024 Project Update | |
Good morning, With 2024 well underway, we are sharing an update on our Power Downtown Toronto project, which includes upgrading underground cables between our Esplanade Transformer Station (TS) located at The Esplanade and Lower Sherbourne St. and Terauley TS located at Bay St. and Foster Pl. The existing underground cables have served the downtown core since the 1950s and need replacing. As part of this, we are building an underground tunnel for the new cables along with entry points at each station (click here for the route). We anticipate the project will be complete and in-service in 2026. | |
What’s new | |

The tunnel is approximately 25m underground, 3m in diameter and 2.5km long. The machine allows most construction to take place underground along the route, which helps minimize disruptions to residents and businesses by reducing noise and road closures. |
What’s next | |
Photo of the new tunnel near the mid-point. | We anticipate the tunnel boring machine will reach Terauley TS over the next few weeks. Once the 2.5 km journey is complete, crews will then need to remove the machinery from the tunnel and entry point using a crane. The tunnel boring machine is slow yet mighty as it has been moving approximately 10 metres a day. Once the machine is removed, crews will continue tunnel construction followed by cable and other equipment installation in 2026. |
Stay in touch | |
We are pleased to have an on-site Construction Ambassador who is available to meet with residents during construction. If you have any questions, please contact Rick Parnell at (647) 969-5744. To be added or removed from this contact list, please email Community.Relations@HydroOne.com. |
Interesting, but I suspect that these cables are to be put in the new Hydro One conduits they are currently installing beside the rails on top of the berm. If they were for the new tunnel I guess they would be stored in the Hydro One yards at each end of the new tunnel. They announced this recently:I wonder if these spools, stored between the Gardiner and tracks, are the new feeders?
230KV noted on the inside of the spool.

Great sleuthing, Dr Watson!The 2.5 km tunnel lines operate at 115KV and after some digging, on the internet, they are supplying 230KV cables.
Maybe the spools were delivery by train? Maybe they don’t have enough room in The Esplanade TS Yard? I counted over 40 spools. Maybe @globalexpress has a better view on the count? Then I found four spools in the TS yard with one matching the ones by the tracks.
I can’t imagine they are installing 230KV lines in ducts on/near the tracks unless they are replacing the overhead lines. Are there any existing buried HV lines under ground in this area? Maybe the new Gardener or the OL Line or the Don flood protection work requires a tower or two to be relocated and they are burning the main feed.
After some more digging I found this
From the USCR TPAP Environmental Project Report of 2018.
I guess we have more fun stuff to watch.

they were delivered by flatbed truck, I got held up by one for 15 minutes going west on Lakeshore while it backed into a driveway. As you might expect in Toronto, this was during rush hour instead of at an off peak time like, say, the middle of the night.^ Tagging @smallspy in case he can shed light on whether the spools were delivered by train.
What’s next |
Crews will continue work inside the underground tunnel over the next year, followed by cable installation and completion of the tunnel entry/access points. We anticipate the upgrades will be complete and in-service in 2026. |
