The story goes this way: Residents of Shag Harbour, Nova Scotia, witnessed strange coloured lights streaking across the night sky before it plunged into the Atlantic Ocean. Was it a UFO? An airplane perhaps? To this day, no one knows for sure.
After watching Steven Spielberg’s latest film, Disclosure Day, the topic of UFOs has been on my mind. Whether by coincidence or not, I came across this fascinating Canadian story about an unidentified flying object reportedly crashing into the waters off Shag Harbour. NS.
As a longtime UFO buff, I’ve noticed that unless you dig a little deeper into Canadian unexplained, you don’t hear many stories about UFO sightings in Canada. And it’s not because these events don’t happen; they do, but they don’t generate the same level of attention as incidents like Roswell. But, rest assured, Canada has its share of unexplained UFO sightings.
This particular story Shag Harbour, intrigued me enough to do my homework on UFO reports along Canada’s East Coast. “Here’s what I found.”
Once a quiet fishing village, Shag Harbour is now recognized less for its cod and lobster industry and more for one of Canada’s most thoroughly documented UFO incidents.
Located at the southern tip of Nova Scotia, this small rural community would become the site of one of the country’s most famous unexplained events. Named after the shag, a bird belonging to the cormorant family, the harbour was barely known outside the region before October 1967. That would change after an extraordinary event that made front-page news across the country.
This is the story of the world-famous Shag Harbour UFO Incident, retold once again.
The Night of the Sighting
The incident began when more than a dozen residents reported seeing several bright orange lights moving across the night sky before descending rapidly into the water.
At about the same time, the Canadian Coast Guard vessel CSL M.V. Mersey was patrolling nearby. Its crew of approximately 20 sailors also reported seeing four glowing orange objects flying in a rectangular formation.
According to witness reports, the objects suddenly descended at roughly a 45-degree angle before striking the water with what sounded like, a loud explosion. The impact reportedly left behind a large patch of glowing yellow foam floating on the surface.
Believing an aircraft had crashed, the crew immediately radioed rescue coordinators and filed an official report with the RCMP.
Search-and-rescue teams were dispatched, but no wreckage or survivors were ever officially found. That word—officially—is important. And no aircraft were reported missing in the area that night either.
Despite numerous civilian and military witnesses, investigators found no conclusive evidence explaining what had fallen into the water. Other than the unusual discoloured foam that suggested something had indeed entered the ocean, nobody knows what.
Military officials even considered whether a Soviet submarine or an undisclosed downed aircraft might be involved, but no definitive explanation was ever discovered.
The event was investigated by civilian authorities, the RCMP, the Canadian Navy and the Royal Canadian Air Force.
Unfortunately, much of what was allegedly witnessed has remained unofficial. Some former military personnel reportedly chose not to speak publicly out of concern for their future in the Navy, while civilian witnesses feared ridicule or unwanted publicity.
But What If There Was More to the story?
One commenter on a YouTube video about the Shag Harbour Incident wrote:
“What’s crazier is that a book just came out tying this event to a NATO exercise off the coast of Shelburne. They were doing mine-removal drills and underwater diving when they supposedly found two crashed UFOs underwater, with two aliens outside working on one of the craft. The book is called Sweep Clear. What’s even stranger is that one of my coworkers, who lived nearby, claimed she encountered three beings inside her home around the same time as the Shag Harbour incident.”
It’s certainly an interesting comment. However, when I researched the claim, I couldn’t find any evidence supporting it. As many UFO stories are shared online, it makes for fascinating reading, but without proof, it remains just another unverified account. Interesting though!
An Enduring Mystery
The Shag Harbour Incident continues to occupy an important place in Canadian UFO history.
There is little doubt that “something” entered the waters off Shag Harbour on October 4, 1967. Whether it was a natural phenomenon, secret military technology, an aircraft, or something entirely unknown remains unanswered.
To date, no wreckage has ever been officially recovered, no survivors have been found, and the case remains unsolved nearly six decades later.
More UFO Sightings Along Canada’s East Coast
While researching the Shag Harbour Incident, I discovered that reports of unexplained aerial phenomena have appeared across Atlantic Canada for decades.
Many sightings are eventually explained as satellites, weather balloons, paper lanterns, or military aircraft. Others, however, remain unexplained despite witness testimony and official investigation.
Some of the more notable reports include:
The Woodstock Triangle (1993): One of the region’s best-known cases involved a woman who filmed a brightly lit triangular object hovering over her backyard for nearly ten minutes.
Saint John (2014): A resident captured video of a mysterious glowing object that appeared to circle the city before moving toward the east-side Irving Oil refinery, leaving the witness deeply shaken.
Historical Reports: The National UFO Reporting Center (NUFORC) has catalogued decades of sightings throughout Atlantic Canada, including Fredericton, Doaktown, and Moncton. Reports describe everything from glowing red lights to tumbling cube-shaped objects.
The late nuclear physicist and respected ufologist Stanton Friedman lived in Fredericton, helping make the province a focal point for UFO research. Exhibits featuring his research and documentation have introduced countless visitors to Canada’s rich history of unexplained aerial sightings.

My Final Thoughts
Whether you believe the Shag Harbour Incident involved extraterrestrials or was simply an event that has yet to be explained, one thing is certain: it remains one of Canada’s greatest unsolved mysteries.
If Roswell built an international reputation around its famous UFO story, perhaps “Shag Harbour” deserves a little more recognition as Canada’s own UFO capital.
