Thematic Sessions
The Humpback Whale World Congress 2025 will bring together experts, enthusiasts, innovators, and decision-makers around key themes aimed at better understanding, protecting, and sustainably coexisting with these giants of the ocean.
Throughout a series of engaging and diverse sessions, we will explore:
Whether you are a researcher, student, artist, manager, fisher, or simply an ocean lover, these themes are an open invitation to collectively shape an ambitious, informed future for humpback whales and marine environments.
Join us in Tadoussac for a unique gathering of knowledge, collaboration, and commitment.

Congress activities
Whale Watching
Since the congress will take place in Tadoussac — one of the best places in the world to observe whales — a whale-watching boat tour will be offered (available as an option when registering).
You’ll also have the chance to observe whales from land every morning, thanks to the incredible location where the Saguenay Fjord meets the St. Lawrence River.
Workshops
Workshops on various topics will be open to everyone for a fee, except for those already registered for the congress. A dedicated registration tab will be available soon for those who wish to attend workshops only. It is also possible to sponsor a workshop on a specific topic — if you're interested, please contact us!
Movie projection, Live performance in danse and music
