Today the tunnel is used by people who know about its secret entrance. Homeless people sometimes use it for shelter and occasionally artists host clandestine vernissages (art exhibitions) and illegal rave parties. While the tunnel beneath the Lachine Canal is definitely spacious, it is also rumoured to be haunted, according to many of its users. Firstly, there are reports of a growling noise that emanates from within the darkness of the tunnel. According to one man who was contemplating sleeping rough in the tunnel, he heard what sounded like a large animal growling menacingly at him, so he decided to abandon his plan.
McCaskill also mentioned a frightening encounter. One day, while going about his daily routine, he heard a sort of demonic growling noise. It got louder and more menacing, causing him to bolt from the building momentarily in a state of fear. On another occasion, he noticed that a cross had subtly burnt itself into the grass outside the Legion without any explanation - nothing had been placed on the lawn that could have formed the religious shape. Concerning the disembodied voices, in addition to whatever was growling, there is also a chorus of women upstairs who sometimes sing to the sounds of a piano; unusual, because the Legion’s piano is downstairs. There is also the mysterious voice of a child, which Ken McCaskill actually managed to record. Late one night in 2014, after he had locked up, he recorded a muffled child’s voice saying something like “Pick up your Tootsie Roll”. The same young voice, in a clearer tone, also asked: “Can I come downstairs now?”
