What country has 20% of the world's freshwater?

Canada: Guardian of 20% of the World’s Freshwater

It’s a staggering fact: despite its relatively small population, Canada is home to about one-fifth of the planet’s surface freshwater. From the vast expanse of the Great Lakes to the remote glacial rivers of the North, the country’s landscape is crisscrossed with lakes, rivers, and wetlands that hold this precious resource.

While only about 3% of Earth’s water is freshwater, Canada plays an outsized role in safeguarding it. With over two million lakes—more than any other country—it’s no surprise that its rivers and lakes sparkle like liquid treasure on the map. Much of this water is concentrated in massive basins like the Mackenzie, St. Lawrence, and Saskatchewan river systems, which feed ecosystems, communities, and economies across North America.

But having 20% of the world’s freshwater isn’t just a point of pride—it’s a responsibility. Climate change, industrial activity, and pollution threaten these vital sources. Indigenous communities, who have stewarded these waters for generations, continue to lead efforts in protecting them. From grassroots advocacy to national policies, Canada faces the ongoing challenge of balancing use with preservation.

And while freshwater may seem abundant here, it’s far from evenly distributed globally. Millions worldwide lack access to clean water, making Canada’s role all the more critical—not just as a holder of water, but as a protector of it.

As temperatures rise and demand grows, the call to act grows louder. Protecting Canada’s lakes and rivers isn’t just about national interest; it’s about global stewardship. After all, water doesn’t just sustain life here—it helps sustain the planet.
