Spooktober 2026: Headless Mary — The Ghost of Griffintown

About this episode

Episode 440: In 1879, Montreal’s Griffintown was a crowded working-class neighbourhood shaped by Irish immigration, heavy industry and life along the Lachine Canal. On June 27, Mary Gallagher entered a tenement at the corner of William and Murray streets, where a morning of drinking with her friend Susan Kennedy ended in a brutal killing for which Kennedy was accused. The crime became one of Montreal’s most enduring ghost stories. For generations, residents have said that Mary returns to the corner every seven years, searching for her missing head. In this Spooktober episode, we examine the documented case, the legend it inspired and the changing neighbourhood that kept her story alive for nearly 150 years.
