Nath Lasselin is an Explorer and a multi award winning Underwater Filmmaker.  She spends her life with the eyes of her youth, always curious to search, to discover and document the world.  Ready to push her own limits and fears, she takes her camera to document her discovery in order to share them with those who will never have the opportunity to see the wonders of the underwater world

She travelled and filmed in more than 50 countries and into the depth of underwater caves on 5 continents.

Women Diver Hall of Fame Inductee

Fellow Royal Canadian Geographical Society


Each springs for the past few years, she packs her winter clothes to diver into the frigid water of the canadian arctic.

When she dives with all kind of sharks including great white shark, she is always careful not to disturb them in their own habitat.

She dove deep wrecks in low visibility, cold waters, braving underwater waves


She has produced and directed 6 underwater documentary films that have been distributed in 25 countries. Each film was a shipper in a new universe, demystifying the underwater cave diving (Facing darkness) and then with the divers fishermen of Isla natividad (Sustainability at Sea), telling the story of the last survivor of the JB King wreck in Ontario ( H2O secrets: JB King), following in the footsteps of John Muir in Alaska (Heen Taak), participating in cave exploration in Mexico to the discovery of human remains (Axis Mundi) and finally his last film Aqua Incognita: made in China At the end of 2017. During her travels in China, she was able to live the rapprochement of individuals at the antipodes and together build to improve their own existence


She motivates others to achieve personal accomplishment and brig people together.  She created and organized 2 times the world record for simultaneous immersion of the largest number of female divers and free divers


And it is through her lectures that she inspires her audience, to go beyond the discovery of our beautiful blue planet. To learn a little more how we can live in harmony with our own environment, to be healthier and happier. The more I travels the world, the more I realize the multitude of small gestures that we can pose to change the health of our close environment.



In our own background

After all those incredible adventures, she realized that the extreme exploration was just a few street away from home. Who really knows what lies in the water of the St Lawrence river?  Who knows the wild life surrounding citizens in big cites? And mostly what about water? Daily we turn on the tap of water, but what do we really know about it?  Whatcan we do more to preserve it in order to have a better living and healthy environment?
