Water pollution in Canada is generally local and regional, and most Canadians have access to safe drinking water and sanitation. However, water pollution is a long-term threat in the country due to population growth, economic development, climate change, and scarce fresh water supplies in certain areas. There are two major types of water pollution in Canada: surface water pollution and groundwater pollution. Groundwater pollution is caused by contaminants from municipal landfill sites, industrial waste disposal sites, leaking gasoline storage tanks, leaking septic tanks, and accidental spills. These contaminants eventually reach rivers, lakes, and oceans, affecting water supplies. Sources of water pollution include point sources, nonpoint sources (NPS), and trans-boundary sources. NPS, which includes unregulated sources such as land development and agriculture, has been reported as a significant and growing threat to water resources in Canada.

What You'll Learn
Municipal sewage and urban runoff
In Canada, there are monitoring programs in place to trace and regulate point source pollution, where pollutants can be traced to a single identifiable source. However, non-point source (NPS) pollution, which includes urban runoff, has not been addressed as vigorously. NPS accounts for a substantial amount of water pollution in Canada and poses significant and growing threats to water resources.
The Canadian federal government has launched several initiatives to respond to water pollution, including the Freshwater Action Plan (2017) and the $1.5 billion Oceans Protection Plan (2017). These initiatives aim to address the long-term threats to water quality in Canada, which include population growth, economic development, climate change, and scarce freshwater supplies in certain parts of the country.

Industrial pollution and industrial waste
Water pollution in Canada is generally local and regional, and most Canadians have access to safe drinking water. However, industrial pollution and industrial waste are major contributors to water pollution in the country.
One example of industrial pollution in Canada is the contamination of the Columbia River by Teck Resources in Trail, British Columbia. This incident not only affected the water quality in Canada but also downstream in the American State of Washington, highlighting the transboundary nature of water pollution.
In addition to industrial waste disposal sites, other sources of industrial pollution in Canada include municipal landfill sites, leaking gasoline storage tanks, and accidental spills. These point sources of pollution can be traced to a single identifiable source, making them easier to monitor and regulate compared to non-point sources.
To address the issue of industrial pollution and protect water resources, the Canadian federal government has launched several initiatives. These include the Freshwater Action Plan (2017) and the $1.5 billion Oceans Protection Plan (2017). These programs aim to mitigate the impacts of industrial pollution and improve water quality in Canada.

Agricultural pollution
Water pollution in Canada is generally local and regional, and most Canadians have access to safe drinking water. However, agricultural pollution is a significant contributor to water pollution in the country.
In 1998, British Columbia reported that NPS was the major cause of water pollution in the province, and these pollutants continue to pose significant and growing threats to water resources. The agricultural industry is one of the major sources of NPS pollution, along with urban and highway runoff, the forestry and mining industries, and marinas and boating activities.
Transboundary pollution is another issue affecting water quality in Canada. An example of this is the contamination of the Columbia River by Teck Resources in Trail, British Columbia, which affected water quality downstream in the American State of Washington.
To address water pollution, the Canadian federal government has launched several initiatives, including the Freshwater Action Plan (2017) and the $1.5 billion Oceans Protection Plan (2017). These programs aim to mitigate the long-term threats posed by population growth, economic development, climate change, and scarce freshwater supplies in certain parts of the country.

Inadequate water infrastructure
Water pollution in Canada is generally local and regional, and most Canadians have access to safe drinking water. However, inadequate water infrastructure is a long-term threat to the country's water security.
Agricultural pollution is another consequence of inadequate water infrastructure. Fertilizer runoff and agricultural wastewater can contaminate water sources with nutrients, pesticides, and sediments, leading to harmful algal blooms and the degradation of aquatic ecosystems. In addition, groundwater pollution from sources such as landfill sites and leaking septic tanks can contaminate water supplies as the contaminants eventually reach rivers, lakes, and oceans.
Transboundary pollution is also a concern, where water pollution originating in one region or country threatens water quality in another jurisdiction. For example, the contamination of the Columbia River in British Columbia by Teck Resources also affected the water quality downstream in the American State of Washington.
To address these issues, the Canadian federal government has launched initiatives such as the Freshwater Action Plan (2017) and the $1.5 billion Oceans Protection Plan (2017). However, more needs to be done to ensure that Canada's water infrastructure is adequate to protect the country's water resources and the health of its citizens.

Transboundary pollution
Water pollution in Canada is generally local and regional, and most Canadians have access to safe drinking water and adequate sanitation. However, water pollution is a long-term threat due to population growth, economic development, climate change, and scarce freshwater supplies in certain parts of the country. The main sources of water pollution in Canada are municipal sewage, urban runoff, industrial pollution and industrial waste, agricultural pollution, and inadequate water infrastructure.
Non-point sources (NPS) of water pollution, which are largely unregulated and include land development and agriculture, also account for a substantial amount of water pollution in Canada. By 1998, British Columbia reported that NPS was the major cause of water pollution in the province and posed significant and growing threats to water resources. The main types of NPS are sediment, nutrients, toxic contaminants, chemicals, and pathogens. Examples of NPS include fertilizer runoff, agricultural wastewater, and stormwater in urban areas.

Water pollution in Canada is caused by municipal sewage, urban runoff, industrial pollution and waste, agricultural pollution, and inadequate water infrastructure.
Surface water pollution and groundwater pollution. Groundwater contaminants include municipal landfill sites, industrial waste disposal sites, leaking gasoline storage tanks, and accidental spills.
NPS stands for Non-Point Sources and refers to pollutants from largely unregulated sources such as land development and agriculture. NPS accounts for a substantial amount of water pollution in Canada and poses significant and growing threats to water resources.
Transboundary pollution is water pollution that originates in one region or country but threatens water quality in another jurisdiction. An example is the contamination of the Columbia River in British Columbia, which affected the American State of Washington downstream.
