Great white sharks are once again making their way to northern feeding grounds, drawing interest from both researchers and coastal communities during the peak summer season. Recent tracking data showing Brookes in the Bay of Fundy and Bella in the Gulf of St. Lawrence highlights an annual migration that is increasingly shaping conversations around boating, beach recreation, and wildlife tourism.
Why the Migration Matters
Great white sharks regularly migrate north during the warmer months in search of productive feeding areas before returning to southern waters as temperatures cool. Researchers describe these movements as a normal and recurring part of the species’ life cycle rather than an unusual event.
Highlighting the species’ migratory behavior, OCEARCH stated, “The sharks’ incredible ability to travel long distances allows them to navigate vast ocean spaces efficiently, moving between productive feeding grounds and warmer winter refuges.”
As shark-tracking technology improves and public interest grows, seasonal migrations are becoming a visible part of the Atlantic coastal experience, drawing attention to the region’s rich marine ecosystem.
Shark Migration Highlights
- Brookes was tagged in Mahone Bay in September 2025 and measured more than 8 feet long and over 450 pounds.
- The young shark recently entered the Bay of Fundy after travelling thousands of miles along the Atlantic coastline.
- Another tracked shark, Bella, weighing approximately 729 pounds, was recorded moving through the Gulf of Maine and into northern feeding areas this summer.
- Scientists say recovering shark populations and abundant seal populations are contributing to more frequent sightings across the region.
Implications for Coastal Recreation and Tourism
While shark encounters remain uncommon, seasonal migrations often prompt increased coastal monitoring, public awareness campaigns, and wildlife advisories around beaches and boating destinations. Sightings can occasionally lead to temporary beach advisories, helping authorities keep visitors informed while maintaining safe access to recreation areas.
Nigel Hussey, an associate professor of biology at the University of Windsor in Ontario, said, “It’s very difficult to estimate how many great white sharks are in Atlantic Canada waters, and researchers would need years of data they don’t yet have to make an accurate calculation.”
“People should not be concerned as white sharks do not wish to eat people. But we do need to ensure people are aware that white sharks are present in our waters — this species is a large predator.”
For travellers, the migration serves as a reminder that Atlantic Canada’s coastline is part of a thriving ocean ecosystem. From beachgoers and kayakers to wildlife enthusiasts and boat-tour operators, many are increasingly viewing the annual return of great white sharks as one of the most fascinating wildlife stories of the summer season.
Wildlife encounters at beaches are rare, but visitors should always heed local advisories. The same safety-first approach applies whether visiting Atlantic waters during shark migration season or destinations such as Puerto Vallarta, where crocodile sightings have prompted warnings.
