In October 1967, the quiet fishing village of Shag Harbour, Nova Scotia, became the site of one of Canada’s most famous UFO cases. Dozens of witnesses, including local residents and RCMP officers, reported seeing a glowing object streak across the night sky before crashing into the harbour. Rescue teams rushed to the scene expecting a downed plane, but no wreckage was ever recovered, and official investigations by the RCMP, Canadian military, and even U.S. agencies failed to provide an explanation. With eyewitness testimony, declassified documents, and unanswered questions, the Shag Harbour UFO Incident remains a mysterious chapter in Canada’s modern history, blurring the line between fact, folklore, and the unknown.
