#31 - The Sorcerer of Anticosti Island

Unsolved Canadian Mysteries

Deep in the misty waters of the Gulf of St. Lawrence lies Anticosti Island, a place of treacherous shipwrecks, ghostly legends, and one of Canada’s most enigmatic figures—Louis-Olivier Gamache, better known as the Sorcerer of Anticosti Island.

Born in 1784 in LeLay, Quebec, Gamache’s life was an odyssey of hardship and adventure. As a boy of eleven, he joined the British Navy, sailing across the world before returning to find his parents dead. With nothing left for him in his hometown, he sought a fresh start, opening a store in Rimouski—only to see it consumed by flames. Misfortune seemed to follow him, but instead of yielding to fate, Gamache carved out an existence on the remote and wild Anticosti Island.

There, he made a home in Baie Ellis, surviving by hunting, fishing, and trading with passing ships. The island’s infamous shipwrecks became an opportunity, as Gamache provided supplies to desperate sailors who washed ashore. But his solitude and resilience soon took on an air of mystery. Was he merely a hardened survivor, or did something more sinister lurk in the shadows of his isolated existence?

Stories of Gamache’s unyielding defense of his home began to spread. He was said to have kept an arsenal of weapons—rifles, pistols, and even bayonets—ready to fend off any who dared intrude. When an armed Innu man once ignored his warning, Gamache shot him in the leg, nursed him back to health, and then sent him away with a grim warning for others: the next man would be shot in the head.

But it wasn’t just his fierce reputation that made Gamache a legend. It was the whispers of the supernatural. According to some, he was not just a man but a sorcerer, capable of calling upon dark forces. One tale tells of his ship, chased by pursuers, vanishing in a fireball—only for the wreckage to never be found. Another speaks of how he could summon the wind at will, leaving other vessels becalmed while his ship sailed on.

Perhaps the most chilling story involves Gamache checking into an inn in Rimouski, ordering two extravagant meals. When the innkeeper inquired about his guest, Gamache coldly replied it was none of her concern. Yet when she later entered his room, she was horrified—both plates had been eaten from, both chairs drawn up to the table. But only Gamache was present. The town soon buzzed with rumors that the Sorcerer of Anticosti had dined with the Devil himself.

Even in death, his legend refused to fade. A trapper named Goudreau discovered Gamache’s lifeless body in 1854 and buried him beside his wife. But some say his spirit lingers, bound to the winds and waves of Anticosti, where the lost souls of shipwrecked sailors still wander.

Who was Louis Gamache? A man hardened by life’s cruelties, a trickster who played upon superstition, or something far more otherworldly? The full story of the Sorcerer of Anticosti Island awaits.
