Rare Great White Shark Encounter in Percé: What Happened and Why Now?

The serene waters of Percé, known for its breathtaking landscapes and world-class diving, recently became the site of an extraordinary and frightening event. For the first time in documented history in the Gaspésie region, a diver was attacked by a Great White shark, sending shockwaves through the local community and marine enthusiasts alike.

The Incident at Le Bilbo Dive Site

The incident occurred on a Wednesday at the renowned Le Bilbo dive site, located just off the coast of Percé. While participating in a group excursion, a diver was suddenly targeted by a Great White. According to the Sûreté du Québec, the victim suffered significant injuries but remained conscious during the rescue operation.

In a swift response to ensure public safety, Plongée Percé, the company organizing the excursions, announced the immediate suspension of all diving activities for the remainder of the season. While the victim’s life is not in danger, the event serves as a stark reminder of the unpredictable nature of the ocean.

Why are Great Whites appearing in Percé?

While the Gaspésie region is home to four shark species—the Great White, the Greenland shark, the Spiny Dogfish, and the Porbeagle—the presence of a Great White this far north was once considered an anomaly. However, the narrative is changing due to climate change.

Rising water temperatures in the Gulf of St. Lawrence are making the region more hospitable for these apex predators. As the waters warm, the migration patterns of Great Whites are shifting, making their presence at these latitudes a more frequent occurrence rather than an exception.

Understanding the Predator’s Behaviour

One of the most debated topics following such attacks is the “why.” Traditionally, it was believed that sharks mistake swimmers or divers for their natural prey, such as seals. However, recent scientific research suggests a different motive.

• Exploratory Biting: A 2023 study indicates that sharks, particularly younger individuals, may bite to better identify and understand their surroundings.
• Mistaken Identity: Despite new theories, the “seal-mimicry” hypothesis remains a possibility in murky waters.
• Tracking Presence: Data from Ocearch shows at least six tagged Great Whites currently in the Gulf, including a 2.7-meter female named Brookes, who has been spotted near Percé.

Is Diving in Canada Still Safe?

Despite the alarm, it is important to put this event into perspective. Shark attacks on humans remain exceptionally rare. According to the Canadian shark attack registry, only 31 attacks have been recorded over the last 300 years. Globally, the Global Shark Attack File reports an average of 60 to 70 incidents per year—a tiny fraction compared to the millions of people who enter the ocean daily.

Ironically, while humans fear sharks, the sharks themselves are in danger. A study published in Nature revealed that shark and ray populations have plummeted by over 70% in the last 50 years.

For those visiting Percé and the Gaspésie coastline, staying informed and following the guidelines of local maritime authorities is the best way to enjoy the beauty of the Atlantic safely.
