What You'll Learn
Canada's government is working to protect water resources
Canada is home to roughly seven per cent of the world's renewable freshwater. The country's water quality is most affected by industrial effluent, agricultural runoff, and municipal sewage pollution. The health and well-being of humans and ecosystems depend heavily on the availability of quality water resources. Water is necessary for biological life and supports global food production, industrial activity, and municipal services.
The Canadian government is working to protect water resources by implementing various initiatives and regulations. In 2017, the federal government launched the Freshwater Action Plan and the $1.5 billion Oceans Protection Plan. These plans focus on improving water resource management, reducing pollution at its source, taking action on toxic substances, monitoring water quality, investing in infrastructure, and developing regulations. The government is also working with First Nations communities to achieve clean drinking water on reserves.
To reduce pollution, the government is regulating specific industries, such as metal mines and pulp and paper, and taking action on toxic and harmful substances through the Chemicals Management Plan. They are also monitoring water quality through a network of specialists who collect data from over 3,000 sites across Canada.
The Building Canada Fund is providing support for municipalities and First Nations communities to upgrade wastewater treatment facilities. The new Wastewater System Effluent Regulations set the country's first national standards for sewage treatment. Additionally, Canada is making international contributions, such as investing in the United Nations Environment Programme's Global Environment Monitoring System, to better understand inland water quality issues.
Through these initiatives and more, the Canadian government is working hard to clean up polluted waters and ensure clean water for all Canadians.

Reducing pollution at the source
One major source of water pollution in Canada is industrial effluent, which includes metal mines, pulp and paper, and the oil industry. To address this, the Canadian government is regulating specific industries and preparing regulations to limit toxic chemicals from getting into freshwater reserves. For example, through the Chemicals Management Plan, regulations are being developed to restrict Bisphenol A (BPA) and Per- and polyfluoroalkyl substances (PFOAs). The government is also addressing the issue of blue-green algae growth in lakes and rivers by introducing regulations to reduce the use of phosphates in household cleaning and laundry products.
Another source of water pollution in Canada is municipal sewage and urban runoff. Municipal waste-water discharges, composed of sanitary sewage and stormwater, can contain grit, debris, disease-causing pathogens, and chemicals. To address this, the Canadian government has implemented the Wastewater System Effluent Regulations, which set the country's first national standards for sewage treatment. Additionally, the government is providing funding to help municipalities and First Nations communities upgrade their wastewater treatment facilities through initiatives such as the Building Canada Fund.
Agricultural runoff and pollution are also significant contributors to water pollution in Canada. Agricultural activities can contaminate water with manure, synthetic fertilizers, pesticides, and other chemicals. To reduce pollution from this source, the Canadian government is working on initiatives such as the Freshwater Action Plan (2017) and the $1.5 billion Oceans Protection Plan (2017), which aim to improve water resource management and reduce pollution at the source.
Canada is also addressing transboundary pollution, which is water pollution that originates in one region or country but affects another. For example, the contamination of the Columbia River by Teck Resources in British Columbia also affected the downstream water quality in the American State of Washington. To address this, Canada has banned the importing, selling, or use of PFOA-containing products since 2008.
By implementing regulations, investing in infrastructure upgrades, and developing initiatives to reduce pollution at its source, Canada is taking comprehensive action to protect its water resources and ensure clean water for all Canadians.

Taking action on toxic substances
Canada has taken several steps to address water pollution, including the launch of the Freshwater Action Plan and the $1.5 billion Oceans Protection Plan in 2017. These initiatives aim to improve water resource management, reduce pollution at its source, and monitor water quality, among other things.
Toxic substances in water are a significant concern in Canada, with toxic metals such as mercury, lead, and cadmium being released into water bodies. These substances can enter the food web and accumulate in the tissues of living organisms, posing hazards to both humans and wildlife even in small amounts. To address this, Canada has implemented the National Pollutant Release Inventory (NPRI), which measures and estimates releases of harmful substances into the water. This data is used to inform the public, identify priorities, and develop strategies to reduce and control these toxic substances.
Additionally, Canada has taken steps to prevent the dumping of toxicants into aquatic environments. For example, the manufacturing and use of DDT and PCBs have been banned, and systems are now in place to prevent the dumping of certain metals and other potentially toxic substances during industrial processes. Some toxicants have been replaced by non-toxic substitutes, and wastewater treatment processes help isolate toxic materials for secure disposal.
The Canadian government has also introduced legislation to address water pollution, such as the Canadian Environmental Protection Act, which defines a substance as toxic if it may enter the environment and have an immediate or long-term harmful effect on the environment, biodiversity, or human life and health. This Act helps identify and regulate toxic substances in the environment.
Furthermore, Canada has amended the Great Lakes Water Quality Agreement with the United States to address aquatic invasive species, habitat degradation, and the effects of climate change. This Agreement aims to restore and maintain the chemical, physical, and biological integrity of the Great Lakes, which have been severely affected by water pollution.
The country is also taking steps to modernize toxicity testing and improve chemical management, as there is a lack of toxicological knowledge for many pollutants. This includes new approaches, technologies, and regulatory changes to better understand and address the impact of toxic substances on the environment and human health.
