Water Pollution Crisis In Canada: Where Is It Worst?

Water pollution is a significant threat to aquatic ecosystems in Canada. The worst cases of water pollution occur in the southern parts of the country, where most people live and most agricultural and industrial activities take place. However, remote and less populated areas may also be affected by pollution from resource-based industries, such as oil-sand and metal-mining developments and pulp mills. Ontario and Quebec have been reported to have the poorest water quality in Canada, with no improvement in water quality over the past two decades.

Southern Canada, where most people live and most agricultural and industrial activities occur

Southern Canada is densely populated and home to many industrial and agricultural activities, making it particularly vulnerable to water pollution. The Canadian federal government has recognised the threat of water pollution and has launched initiatives such as the Freshwater Action Plan (2017) and the $1.5 billion Oceans Protection Plan (2017) to address the issue. However, according to a report from Environment and Climate Change Canada, water quality in the country has not improved in the past two decades. Raw sewage continues to be dumped into waterways, and regional waterways with worsening quality include Ottawa's Rideau River, Toronto's Humber and Don rivers, and Quebec's Chateauguay, Jacques-Cartier, and la Petite Nation rivers.

One of the worst cases of water pollution in Canadian history occurred in northwest Ontario when a pulp and paper operation owned by the British conglomerate Reed Paper Group discharged about 10,000 kilograms of mercury from their chloralkali plant in Dryden into the Wabigoon River between 1962 and 1970. The mercury contamination of the Wabigoon River system was extensive and also affected the neighbouring province of Saskatchewan, resulting in a lawsuit against Reed Paper.

In addition to southern Canada, remote and less populated areas of the country may also be affected by pollution from resource-based industries, such as oil-sand and metal-mining developments and pulp mills.

Ontario and Quebec, which have the poorest water quality in Canada

Water pollution in Canada is generally local and regional, and most Canadians have access to safe drinking water. However, Ontario and Quebec have the poorest water quality in the country. According to a report from Environment and Climate Change Canada, water quality has deteriorated at 24 sites in these provinces over the past two decades, with no improvement at any site. This is largely due to raw sewage being dumped into waterways.

In Ontario, the Don River in Toronto and the Wabigoon River in the northwest of the province have been particularly affected by pollution. The Don River, which flows into Lake Ontario, is flanked by the Gardiner Expressway. Between 1962 and 1970, a pulp and paper operation owned by the British conglomerate Reed Paper Group discharged about 10,000 kilograms of mercury from their chloralkali plant into the Wabigoon River. This contaminated waterways in the neighbouring province of Saskatchewan and resulted in a lawsuit. The Wabigoon River was still highly contaminated as of 2016.

In Quebec, the Yamaska River was one of the most polluted rivers in the province in 1997 due to agricultural waste and pesticides. Other rivers in Quebec with worsening water quality include the Chateauguay, Jacques-Cartier, and la Petite Nation rivers.

Water pollution in Canada is caused by municipal sewage, urban runoff, industrial pollution and waste, agricultural pollution, and inadequate water infrastructure. Population growth, economic development, climate change, and scarce freshwater supplies in certain areas contribute to the problem. The Canadian federal government has launched initiatives to address water pollution, including the Freshwater Action Plan and the $1.5 billion Oceans Protection Plan, both introduced in 2017.

Northwest Ontario, where a pulp and paper operation discharged about 10,000kg of mercury into the Wabigoon River

Water pollution in Canada is generally local and regional, and most Canadians have access to safe drinking water. However, the worst cases of water pollution occur in the southern parts of the country, where most people live and most agricultural and industrial activities take place.

One of the worst cases of water pollution in Canadian history occurred in Northwest Ontario, where a pulp and paper operation discharged about 10,000kg of mercury into the Wabigoon River between 1962 and 1970. The operation was owned by the British conglomerate, Reed Paper Group, and the mercury came from their chloralkali plant in Dryden. The mercury contamination of the Wabigoon River system was extensive, and the discharge contaminated waterways in the neighbouring province of Saskatchewan, resulting in a lawsuit against Reed Paper. The Wabigoon River was still highly contaminated as of 2016.

This incident is a stark reminder of the dangers of industrial pollution and the long-term environmental damage it can cause. It is also a reminder that appropriate controls and regulations must be in place to prevent such disasters from occurring. While population growth and industrialization are ultimately the causes of water pollution, it can be prevented if the discharge of waste materials is properly controlled and managed.

In addition to industrial pollution, water pollution in Canada is also caused by municipal sewage, urban runoff, agricultural pollution, and inadequate water infrastructure. The Canadian federal government has launched several initiatives to address water pollution, including the Freshwater Action Plan and the $1.5 billion Oceans Protection Plan, both launched in 2017.

Despite these efforts, water pollution remains a significant issue in Canada, particularly in Ontario and Quebec, which have been reported to have the poorest water quality in the country. Regional waterways with worsening quality include Ottawa's Rideau River, Toronto's Humber and Don rivers, and Quebec's Chateauguay, Jacques-Cartier, and la Petite Nation rivers.

The Yamaska River, Quebec, which was one of the most polluted rivers in the province in 1997

Water pollution in Canada is generally local and regional, and is caused by population growth and industrialization. The worst cases of water pollution occur in the southern parts of the country, where most people live and most agricultural and industrial activities occur.

In 1997, the Yamaska River was one of the most polluted rivers in the province of Quebec, mainly because of agricultural waste and pesticides. Quebec has the poorest water quality in Canada, according to a report from Environment and Climate Change Canada. The report states that water quality deteriorated at 24 sites between 2002 and 2020, with no improvement in the past two decades due to raw sewage being dumped into waterways.

The Canadian federal government has launched initiatives to respond to water pollution, including the Freshwater Action Plan (2017) and the $1.5 billion Oceans Protection Plan (2017). However, despite these efforts, water pollution remains a significant issue in Canada, particularly in southern regions and populated areas.

Toronto's Humber and Don rivers, which have worsening water quality

In 1997, the Yamaska River was one of the most polluted rivers in the province of Quebec, mainly because of agricultural waste and pesticides. More recently, a report from Environment and Climate Change Canada said that Ontario and Quebec have the poorest water quality in the country. The report stated that "calculated trends using data from 2002 to 2020 show no site with improved water quality. During that same period, water quality deteriorated at 24 sites." Regional waterways with worsening quality included Toronto's Humber and Don rivers. The Don River empties into Lake Ontario, and is flanked by the nearby Gardiner expressway.
