Along with Lake Erie, Lake Ontario is the most polluted of the Great Lakes. This contributes to potential health risks associated with bathing in its waters, an issue that the other three Great Lakes do not add to the mix.

Yes! Lake Ontario offers fantastic swimming at many beaches. Not all beaches are 'public beaches', some are naturally occurring 'wild beaches' along Lake Ontario's shoreline. Local Health Units often test water quality at public beaches and lifeguards may supervise swimmers in designated swimming areas.
Dry yourself off with a towel as soon as you come out of the water. If possible, have a shower and dry off right away. However, showering will not remove any larvae that have already burrowed under your skin.
If there is scum or algae visible in the water, it won't be clean enough to swim in. There are also natural hazards to outdoor waters compared with pools, especially in the summer. Blue-green algae is a type of bacteria naturally found in lake ecosystems.
In September 1954, 16-year-old Marilyn Bell became the first person to swim across Lake Ontario. Originally, the Lake Ontario swim had been planned by the Canadian National Exhibition (CNE) as a publicity event that offered American marathon swimmer Florence Chadwick $10,000 to cross the lake.
The Great Lakes are not (noticeably) salty because water flows into them as well as out of them, carrying away the low concentrations of minerals in the water, writes Michael Moore of Toronto. Eventually, this water, with its small load of dissolved minerals or salts, reaches the sea.
Stay out of the water ifCloudy water can be a warning that there are more germs in the water than normal. Discolored or smelly water could mean there is a harmful algal bloom (HAB) in the water.
While that is true, it's not as simple as turning on a tap at home or dipping your bottle below the water's surface to fill it. Untreated water found in lakes, rivers, ponds, etc. isn't safe to drink. It can contain waterborne parasites and diseases like Giardiasis (also known as beaver fever) or E.
The State of the Great Lakes 2022 Report by the Michigan Department of Environment, Great Lakes and Energy have analyzed and reported that Lake Superior and Lake Huron are rated as “good” ecosystems as Lake Michigan and Lake Ontario are rated “fair” and Lake Erie was ranked as “poor.”
Lake Ontario continues to be a good source of high-quality drinking water. Toxic chemicals monitored in Lake Ontario are assessed as Fair and long-term trends indicate that concentrations are declining, including declines in contaminant concentrations in fish filets.
Randle Reef is now considered the largest contaminated site on the Canadian side of the Great Lakes and the second-most contaminated site in Canada after the Sydney Tar Ponds in Nova Scotia. The volume of contaminated sediment in the Hamilton Harbour could fill up three hockey arenas.
Pools also tend to be much cleaner than natural lakes. This is because most pool owners take extra care to make sure the pool is sanitized, oxidized, and pH balanced on a regular basis. You're far less likely to pick up an infection from swimming in the local pool.
