I noticed this post on this website - https://www.facebook.com/Historic-Ha...MELINE&fref=nf regarding the tunnels under Halifax:

Mystery Tunnels Beneath The Streets Of Halifax
Will we ever get to the bottom of this mystery?
Everyday the people of Halifax walk over mysterious tunnels beneath the city's oldest streets. Their origin and purpose remains a mystery to this day. The tunnels appear to run under the oldest streets below the citadel : Prince, George, Sackville, and Duke.
The stone chambers were first discovered under the streets of Halifax in 1919. During routine street work, workers broke through the ceiling of one of the chambers at the top of George Street just below the town clock.
Initially, these tunnels were dismissed as former sewage tunnels leading down from the fort, however samples were taken from the floorboards of the tunnels and tested for traces of human biological matter. Results came back that this was not a sewage system. So the mystery continues...
Another myth says that the British military built tunnels between the Halifax Citadel and Georges Island, two of the forts that defended the port. While it is a romantic idea that the military covertly moved under the harbour, it is a myth. While studying the harbour, GSC scientists used seismic-reflection systems to peer beneath the harbour bottom and produce images of the layers of sediments and rocks. The result? Images of the seabed between the island and the shoreline show no evidence of tunnels.
Access points have been sealed over in the Dennis building (George St) and the basement of the Bluenose Restaurant (Duke St) - although sealed off, is still clearly visible.
