What Are the Most Common Issues in Canada's Drinking Water?

According to the 2016 Canadian Water Attitudes Study, about one-quarter of residents reported having experienced a boil water advisory, yet 84 percent feel confident in the quality of the tap water in their home.

As wide-ranging as each province and territory, so are the water quality and problems that affect residents across Canada. From the many lakes, rivers, and watersheds, Canada is rich with natural water sources from which to draw drinking water, creating just as many opportunities for that water to experience problems and issues as it makes its way to your home.

Hard Water

Water that comes from lakes and other surface water sources tends to accumulate a larger concentration of dissolved minerals like calcium, iron, magnesium, and manganese, leaving it hard and prone to problems around the house, including:

  • Low-performing appliances
  • Soap scum and scale buildup
  • Dry, itchy skin
  • Spotty, cloudy glassware


Chlorine is often used as an additive during the water treatment process to remove the presence of bacteria in surface water sources. Although the chemical effectively disinfects water, it can accumulate in excess, leaving the unpleasant swimming pool-like scent behind.

Metals and Impurities

Aging pipes, water mains, and wells can corrode, leaching metals into your drinking water — arsenic, lead, copper, and mercury are just a few to watch out for since they can be hazardous to your health.


Water that has that unpleasant rotten-egg smell is often caused by seasonal conditions in lake water, temperature fluctuations can cause the bacteria responsible for hydrogen sulphide to peak during warmer months.
