Final answer:
Canada contains around 20% of the world's total freshwater supply.
Step-by-step explanation:
The distribution of Earth's water shows that only 2.5% of the planet's water is freshwater, and less than 1% of that freshwater is easily accessible. Most of the freshwater is locked up in ice and in the ground, with only a small percentage being surface water. Canada is known for its abundant freshwater resources, and it contains around 20% of the world's total freshwater supply.
