The Shag Harbour Incident - Canada's Roswell

In this episode of Mysteries of UFOs, we explore the Shag Harbour Incident, often called Canada's Roswell. On October 4, 1967, multiple witnesses in the fishing village of Shag Harbour, Nova Scotia, saw a glowing, diamond-shaped object with flashing lights descend into the ocean. Believed to be a plane crash, rescue efforts and military divers searched the waters—but no wreckage was ever found. The Canadian government officially labeled it a "UFO," making it one of the rare cases with formal recognition. Despite theories ranging from military experiments to extraterrestrial craft, the case remains unexplained more than 50 years later and is remembered as one of the most credible and mysterious UFO events in history.
