Ocean and Freshwater Connections

With two million lakes and more than 8500 rivers, Canada is a water-rich country. Surrounded by three oceans, it also has the longest coastline in the world.

The Canadian Museum of Nature actively conducts research on marine and freshwater species, supports conservation, and contributes to public education on water-related topics.

The UN has proclaimed a Decade of Ocean Science for Sustainable Development (2021–2030). Oceans stabilize climate and support life on Earth. Learn about the museum's research and education on marine species, as well as meaningful collaborations.
