The Water Survey of Canada (WSC) is a scientific branch of Environment and Climate Change Canada, responsible for monitoring the nation's freshwater resources. The WSC maintains Canada's hydrometric data network, widely referred to as HYDAT. Previously over 2,500 hydrometric gauges were maintained.
Three large 5-year state-of-environment reports were prepared by Environment Canada between 1985 and 1996 and the National Environmental Indicators Series saw reports and bulletins released from 1990 to 2003. Environment Canada's focus turned to a consolidated May 2003 proposal from the National Round Table on Environment and the Economy. The ...
According to the Environment Canada, the following sectors account for the following shares of municipal water use: 52% residential users; 19% commercial users; 16% industrial users; 13% leakage. [44] However, a different part of the same web site of Environment Canada states that leakage losses are actually much higher at "up to 30%". [45
Environment and Climate Change Canada is the federal department in charge of conserving and protecting Canada's water resources. The Water Act (2000), a federal legislation, "supports and promotes the conservation and management of water, including the wise allocation and use of water.".
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).
Environmental issues in Canada include impacts of climate change, air and water pollution, mining, logging, and the degradation of natural habitats.As one of the world's significant emitters of greenhouse gasses, [1] Canada has the potential to make contributions to curbing climate change with its environmental policies and conservation efforts.
In June 2024, the Canada Water Agency, was established through the Canada Water Agency Act.
