Toronto’s tap water comes from the pristine Lake Ontario, serving millions of people as a freshwater source. The transformation from lake water to clean, safe tap water starts at four primary water treatment plants located throughout Toronto. These facilities play a fundamental role in meeting strict safety standards, ensuring the tap water is safe for human consumption.

The water treatment process at these plants, including the city’s water treatment plants, the Island Water Treatment Plant, and the Harris Water Treatment Plant, involves multiple steps designed to remove impurities and protect public health. At the Island Water Treatment Plant, for example, the treatment process includes the following steps:

  1. Chlorine is added to disinfect the water and inactivate any potentially hazardous bacteria.
  2. Aluminum sulfate is utilized to eliminate impurities and enhance the taste and clarity of the water.
  3. Carbon is used to further remove impurities and improve the quality of the water.

Safety standards for Toronto’s drinking water

Toronto tap water is subject to rigorous safety standards enforced by the city, provincial governments, and public health authorities, including the Safe Drinking Water Act. Such regulations ensure that the water is clean, safe to drink, and nutritious. Toronto’s water is monitored hundreds of times daily, regularly tests checking for the presence of contaminants such as phosphoric acid. The pH of Toronto tap water typically ranges from 7.4 to 7.8, making it safe to drink.

Another important component of Toronto’s tap water safety is the addition of fluoride. Fluoride is added during the treatment process to help protect against and prevent tooth decay. If you’re concerned about fluoride levels in your tap water, you can opt for bottled water that does not contain fluoride.

Toronto also invests significantly in maintaining and modernizing its water infrastructure, following guidelines set by Toronto Public Health. This helps prevent contamination and guarantees a reliable water supply.

Taste and odor of Toronto tap water

Some might discern an earthy or chlorine taste and odor in Toronto tap water occasionally. This is a result of the treatment process and does not indicate poor water quality. The taste and quality of tap water can be influenced by factors such as the treatment process, the age and condition of pipes, and individual preferences for water tastes.

An earthy or fishy smell in Toronto drinking water is attributed to an increased concentration of algae in Lake Ontario, typically seen from late summer to early fall. Although the taste and odor may be different from what you’re used to, rest assured that Toronto’s tap water remains safe and clean to drink.

Comparing Toronto tap water with bottled water

A comparison between Toronto tap water and bottled water reveals that tap water is generally perceived as safer. This is because:

  • Tap water undergoes stricter regulations and testing than bottled water.
  • Municipal water is tested multiple times a day to ensure consumer safety.
  • Bottling plants are inspected annually by the Canadian Food Inspection Agency (CFIA) to guarantee compliance with health standards.

In addition to safety concerns, the environmental impact of bottled water should be considered. The bottled water industry produces a significant amount of plastic waste, taking up to 400 years to decompose. The recycling rate for plastic bottles in Toronto has been reported to be as low as 51.6% in 2015. Therefore, choosing tap water over bottled water is not only safer but also more environmentally friendly.

To further minimize your environmental impact, consider using a reusable water bottle and filling it with tap water or filtered tap water. Not only will you be making a more sustainable choice, but you’ll also save money since tap water is far cheaper than bottled water.

Potential contaminants in Toronto tap water

Despite Toronto tap water being safe to drink, awareness of potential contaminants is crucial. These include:

  • Lead.
  • Chlorine by products.
  • Microplastics.
  • Polyfluoroalkyl substances.

Nevertheless, the concentration of such harmful substances and potential contaminants is usually low, staying within acceptable range of safe thresholds.

Lead contamination in tap water is a recognized concern for buildings built before the mid 1950s. To reduce the risk of lead exposure, particularly for young children, the City of Toronto recommends using a water filter as the most convenient and affordable solution.

A water filter can further mitigate the risk of ingestion of high levels of chlorine by products, microplastics, and PFAS. Although Toronto tap water is already safe to drink, a water filter can provide additional peace of mind and improve the taste and smell of the water.

Hardness of Toronto water: effects on hair, skin, and appliances
