Water Availability
Fact: Canada contains ~7% of the world’s renewable water. 3300 km3/yr
Global Fresh Water Resources Per Person
See Water Deficiency & Surplus on pg 85 of Atlas
Areas in Canada where water demand is almost as the
same amount as the available water
In 2010 we used: 45.08 km3/yr
Which is 1,330 m3/per Canadian per year 20 % - was used in homes69% - was used by industry12 % - was used in agriculture
