Shag Harbour UFO Incident — Object Crashes Into Nova Scotia Waters, Navy Searches

On the night of October 4, 1967, multiple witnesses across Nova Scotia, including RCMP officers and civilians, observed a large object with flashing lights descend rapidly and impact the waters of Shag Harbour. The object left a trail of yellow foam roughly 80 feet wide on the surface. RCMP officers arrived quickly and were joined by Coast Guard and fishing vessels in searching the area. Divers found no wreckage but confirmed the disturbed area on the water's surface. The Canadian government officially logged the incident as an "unidentified flying object" — one of the few times a government acknowledged such a crash designation. Subsequent accounts from Canadian military personnel suggested that the object had moved underwater along the sea floor toward the neighboring harbour at Shelburne, where a classified military submarine detection facility was located. A second object was reported to have joined the first before both accelerated away. Declassified Canadian documents confirmed official interest in the case. The Shag Harbour incident is unique in that the Canadian government never offered a mundane explanation and the documentation trail is more intact than most comparable cases. The town has since embraced the event and it is commemorated locally.
