fresh water supply vary from five to nine to twenty per cent of the world's fresh water supply,

depending on how one defines fresh water (whether meaning available, usable, or just existing). Growing populations, industries and irrigation will cause a third of the world's population to face a severe shortage of water in less than fifty years. This shortage has resulted in a lot of research and precautionary methods around the world, and in water rich countries such as Canada. The research concludes that Canada has an obligation to use water wisely to preserve water resources for future generations.

According to Environment Canada, good water is “free from disease-causing organisms, harmful chemical substances, radioactive matter and has no bad odours or colour”. The water cycle has allowed the amount of water on Earth to remain the same over the past four billion years. Recently concerns that the Earth’s population may be ruining the water supply have been unveiled. Of all the water on Earth, 97.5 per cent is seawater and three-quarters of the remaining two and a half per cent is clean water locked in polar ice caps. This

The Federal Water Policy addresses the management of water resources. The policy “encourages the use of freshwater in an efficient manner to support life of present and future generations”. The federal government has defined two main goals: “To protect and enhance the quality of the water resource”, and the second is to “promote the wise and efficient management and use of water”. The policy stresses the promotion of the "polluter pays" principle, which will send the expected costs of pollution of the water to those who are responsible.

leaves 0.635% of usable clean water. Environment Canada clarifies that water usage must decrease: “Environmental scientists insist that the use of water must drop, perhaps by as much as 10 per cent globally over the next 25 years, to protect the water systems that sustain life for billions of people.” “The average person needs only between 20 and 40 litres of water a day for drinking and sanitation, however, every Canadian uses about 326 litres of water a day,” the scientists explain. The world’s fresh water is gradually disappearing because of carelessness. Of the total world's freshwater supply, about one third is found underground, and when many rivers have been dammed, creating very dry land, the water cycle is disrupted causing the ground to become increasingly dry.

As the world uses up its water resources, countries that lack water have asked Canada to assure them that if there were a water shortage in their country, that Canada would sell or provide water to them. Many questions have been asked, such as if Canada has the right to refuse water to the thirsty. Water in some situations now costs more than oil and soon
