Is It Safe To Drink Tap Water In Toronto

Toronto is one of the most populated cities in Canada, with 9 million people living in it, having highly dense trees, and people from more than 200 ethnicities in it.
With rich demographics, and having more than 25000 lakes, rivers, and water streams, the whole city is supplied with water from Lake Ontario.

Though the Ministry of Environment, Conservation, and Parks maintains the water quality, the lake’s water is pulled through a thick network of pipes, treated, and added with chlorine, fluorides, ammonia, and other cleaners to remove contaminants and improve overall quality. But is it safe to drink tap water in Toronto?

Whether you’re new to Toronto or a lifelong resident, the question often arises: Is tap water in Toronto safe to drink? In this discussion, we’ll explore the water quality, potential impurities, health risks, and the financial costs associated with drinking tap water in Toronto.

What Is Toronto Water Quality, And Is It Safe To Drink Tap Water?

The water quality of Toronto is declared safe by the Water Regulating Authorities. The water is tested every six hours, added with chlorine, fluoride, and phosphoric acid, and then sent to multiple water stations, pressure pumps, pipes and other resources to be used.
However, the water isn’t routinely checked for hardness or microplastics, and increased levels of lead in older plumbing systems can pose significant health risks. Since Toronto’s water comes from Lake Ontario, it’s important to understand the lake’s water quality, how it’s treated, and what tests are performed before the water is deemed suitable for consumption.

While Toronto tap water meets safety standards, the potential presence of impurities like microplastics and lead suggests that additional precautions, like home filtration, may benefit some households.

Where Does Toronto Get Its Water From?

Though Toronto has more than 25,000 natural water resources, including waterfalls, rivers, canals, and lakes, only Ontiaro’s water is used to provide drinkable water in taps. Since such a populated city uses water from one lake only, it is important to know what characteristics it has.

Toronto Public Health ensures that the necessary tests are conducted to maintain healthy water quality. The water from Lake Ontario is pumped directly to four water treatment plants, which then supply 18 pumping stations and 11 underground reservoirs. These facilities filter and treat about 1 billion litres of water per day, operating 24/7 to meet the city’s needs.

Additionally, Toronto has four elevated storage tanks and over 5,000 km of water mains that deliver treated water to residential, commercial, and industrial areas across the city.

What is the Water Treatment Process in Toronto

When you are figuring out all the pros and cons of Toronto’s tap water, it is important to know the water treatments the tap water goes through and what is the frequency of these tests. As the quality of water keeps changing from time to time, seasonal factors, algae, and other environmental factors change the chemistry of water.

is toronto water safe to drink

  • Firstly, large pipes, 1 to 5 kilometres far away from the shores collect the water from the lake.
  • The lake water is passed through screens to check everything about its chemical composition, impurities present, and the amount of different elements in it. Then large debris particles are collected and the water is disinfected either through chlorine or ozone.
  • Then the floc(accumulation of large particles) is collected by adding alum or polyaluminium chloride.
  • Afterwards, the water is passed through settling basins, where larger particles (if any) then it is passed a series of gravel, sand, and carbon, which is useful in removing impurities and micro-organisms.
  • Before supplying this water to your household, chlorine, fluoride, phosphoric acid, and ammonia are added for disinfection, bone and teeth health, corrosion control, and balancing the chlorine respectively.
  • The water is then sent to substations, to pump through the pipelines to your homes.

Though this water fulfils the health standards of Canada, it is not tested for its hardness and microplastics, and no post-filtration testing is done. Whatever amount of microplastics Toronto water has, it is deemed to be safe as there is no technology available to check microplastic levels in tap water. You get drinkable water with unknown amounts of nutrients, hardness levels, and any present contaminants (unfiltered).

How Often Is Toronto Water Tested?

Ontario’s lake water is tested every six hours in labs for its detrimental effects.
Moreover, 20,000 tests are conducted in labs at different water filtration plants and 15,000 tests for different types of bacteria. Thus, more than 410,000 tests are performed during one year.

Can You Drink Toronto Tap Water?

Is tapwater drinkbale in Toronto? This question is still relative. Water chemistry changes daily, and the safety limits too. Some contaminants are banned in Europe, but not in Canada. So drinking tap water can bring you ailments like hepatitis, liver damage, and stomach issues in case your water is contaminated and not tested before use.
Normally water supplied at your tap is safe to drink, the main culprit might be the pipeline that brings filtered water to your tap. It may contain rust, lead, chlorine by-products that reside in pipes, unregulated microplastics, and PFAS.

Although tests are regularly performed and various measures are taken to clean the water sourced from Lake Ontario, it’s important to understand just how polluted the lake can be and whether these treatments are sufficient to ensure safe drinking water.
Contaminants such as industrial discharge, agricultural runoff, and plastic waste continue to impact the lake’s water quality. While municipal authorities test and treat the water for many pollutants, questions remain about whether these tests fully address the presence of microplastics, lead, E. coli, and other harmful substances.
Let’s explore more about the quality of Lake Ontario’s water and the effectiveness of these purification processes.

Why is Lake Ontario Polluted?

Lake Ontario is polluted because it accumulates contaminants from other lakes including agricultural runoff, industrial discharge, and commercial wastage.

Plastic And Trash

Many factors contribute to the rise in plastic and trash in Ontario Lake. These include local improper disposal of bottles, disposable plastic crockery at beaches and other waste material, and direct littering of the water.

Storm Water And Sewage Mixing

Rainwater washes debris, dirt, plastic, and trash from the streets, roads, and walkways, that directly run off to the storm drains and rivers, ending up into Lake Ontario. If the sewage water gets mixed with rainwater runoff, it also adds up to lake water.

Lead Risks In Aging Plumbing

Even if the water at your faucets is filtered and cleaned through your municipality authorities, old pipes may increase the lead %age in your drinking water. The industrial run-offs illegally added to the lake, or via improper disposal may also increase lead amounts in lake water, which also adds up to your tap water.

Lake Ontario Beach E. Coli Concerns

E.Coli is a bacteria living in the intestines of warm-blooded organisms, including humans. It originally stems from the gut system. Usually, it is your gut bacteria that keep you healthy, but the Shiga toxin-producing E. coli (STEC) bacterium, causes food-borne health concerns like UTI, pneumonia, diarrhoea, and some serious ailments in severe exposure.
E.Coli adds up to Lake Ontario either from stormwater, rainwater runoff, improper disposal of hospital waste, or fecal matter directly to waterways, rivers, and lakes leading to Lake Ontario.

Risks Of Chlorine Byproducts

Though the water is cleaned at government water stations before supplying to your taps, it may have indirect pollutants. The chlorine often reacts with microplastics (which are neither checked nor regulated )

Localized Contamination

In many places, locals add their disposals to Ontario Lake. Though this is illegal and Canada’s government has made strict policies against such individuals, there are sites where proper regulation is not possible because of geographical barriers. Such contaminations add up to the overall pollution of lake water.

Needles And Other Debris

Illegal dumping or improper disposal of syringes may add up to waterways. These waters ultimately fall into Lake Ontario, causing higher pollution to aquatic life and human water ingestion.

Agricultural Runoff

It is the wastewater from agricultural land flowing to the nearby water bodies like rivers or lakes, that ultimately add the highest levels of nitrogen, phosphorus, and fertilizers to the lake’s water.

Dead Fishes Across Lake Ontario

When a large number of fish die in a lake, their bodies remain there until they decompose. This decomposition leads to nutrient imbalance in the lake by adding phosphorus and nitrogen increasing the production of algae and overall water pollution. This water pollution not only harms other aquatic life but also poses serious health hazards if humans come in contact with this water.

Oily Water Near Lake Ontario

Industrial or commercial facilities add oils or oil-based discharge products either illegally or through improper disposal. Other causes of oily water are rainwater runoff or boating activities in the lake. This causes an increase in contaminants in water resulting in poor quality for drinking purposes.

Musty, Earthy Odors And Tastes

Musty and earthy odors in your tap water, are mainly because of the presence of algae and dead fish in lake water. You also get a bad taste when this water is chlorinated before reaching your household.

Is Toronto Water Hard?

Does Toronto have hard water? The answer is “yes”. Generally, groundwater is harder than lake waters. Lake waters are considered soft water because of their natural resources and the series of processes they go through during filtration. But surprisingly, Toronto water is hard. It has an increased amount of calcium and magnesium and their compounds, leading to a hardness level of 6 to 7 grains per gallon.
Hard water may not cause health hazards, but scale buildups in faucets and electric heaters can cause property damage.
Before you install a water filtration system, make sure to have a water hardness test. At Watermart, we offer water testing services to fully understand your water filtration plant’s needs. Call our experts to get a quote.

Is It Necessary To Have A Water Filter In Toronto?

Toronto was the first city to start chlorinating water to kill bacteria, viruses, parasites, pesticides, and other pollutants after the epidemic of typhoid in 1800. The Ministry of Environment and Parks is very concerned about regulating water quality as per Canadian standards.
However, having water from one lake in such a populated city may compromise the quality of the water because of the pipelines and other uncontrollable factors. Installing a water filtration plant is a wise decision, as you may get healthy water at a reasonable cost.
