Darkness shrouds the infamous Blue Ghost Tunnel, one of the Niagara region’s most haunted locations. Built in 1876 for the Grand Trunk Railway, this 713-foot limestone structure sits between locks 18 and 19 of the former Third Welland Canal in Thorold. The tunnel earned its spooky nickname from the blue mist that visitors have reported seeing inside.
The tunnel’s haunted reputation stems from its tragic history. During construction in 1875, a 14-year-old boy was crushed by falling rock. Later, in 1903, two firemen died in a train collision near the entrance. In total, 107 deaths occurred during the building of the tunnel and surrounding canal, creating what many believe is a hotspot for paranormal activity.
Blood-soaked history fuels the tunnel’s haunted legacy—over 100 souls lost during its creation, their spirits seemingly trapped between worlds.
Visitors and investigators report strange experiences inside the tunnel. Many hear unexplained voices, footsteps, and music. Some see a spectral dog, floating balls of light, or the ghost of a woman in a white dress nearby. Paranormal teams often detect EMF spikes and sudden temperature drops inside.
The physical condition of the tunnel presents challenges for visitors. One entrance is blocked off, while the other end is underwater. Inside, algae creates a phosphorescent glow that adds to the eerie atmosphere. The structure is unstable and slowly sinking into the ground. Walking through the tunnel requires careful navigation around the old railroad tracks that remain visible within the tunnel floor.
Access to the Blue Ghost Tunnel is restricted. The entrance is gated and locked, as it sits on private property. Trespassing and vandalism have become ongoing problems. Officials warn that the crumbling infrastructure poses safety risks to those who enter without permission.
Despite access restrictions, the tunnel’s reputation continues to grow. It’s been featured on paranormal TV shows and documentaries, becoming a subject of local legends and urban myths.
Paranormal investigators use EMF detectors, night vision cameras, and audio recorders to capture evidence of the supernatural.
The Blue Ghost Tunnel remains a fascinating piece of Niagara’s history, whether one believes in ghosts or not.
