The G.E.C.O. complex was built in 1940 and 1941 during world war 2. With over 170 buildings and over 5 kilometers of tunnels, "General Engineering Company of Ontario" {G.E.C.O.} assembled and filled munitions such as fuses, primers, tubes, gaines, tracers, igniters and chemical explosives. At their peak production they had over 5,300 employees working here. The tunnels were built with concrete {7ft high and 10ft wide} to protect the G.E.C.O. employees from weather and possible air raids and explosions. The last few remaining buildings have been recently demolished, the tunnels filled in with debris from the demo(a)s, and new buildings are being built over top the old tunnels.

More information can be found in the autobiography book, "Corky, Peggy and the Goldfinch".

I did some research and visited an auto shop in the area. Owner confirmed a hatch into the tunnel exists in his building but it is apparently used as storage so he wouldn't agree to let me in. There are apparently 20 original GECO buildings still standing.

I'm not sure if it's possible to get in. In the voting weekend days I'll drive by and see if there is still a way in. I doubt it as it looks like they have built a commercial shopping complex over the area

crimson, also looking for an entry point for any tunnels still left. it doesn't make sense that if there were 5kms of tunnels then none of them are still there? must be some way in or some section that's abandoned.

My wife, Barbara Dickson, wrote a book on GECO in 2015 titled "Bomb Girls: Trading Aprons for Ammo". In it she documents the history, management, processes and local geography including the tunnels and walkways that encompass the 386 acre site at Warden and Eglinton. The tunnels no longer course between the buildings. They exist as basements to their respective buildings of which there are about twenty.
