Absolutely! To ensure safe drinking water, the Town of Niagara-on-the-Lake takes drinking water samples throughout the system every week and has the samples tested for Chlorine, E. coli and other bacteria that may be present.

Yes, you can safely drink the tap water in Niagara-on-the-Lake, Ontario. The town’s water supply is managed by the Niagara Region and is sourced from the Great Lakes, primarily Lake Ontario. As of early 2026, the water undergoes rigorous treatment at the Decew or Niagara Falls water treatment plants, which utilize advanced filtration and disinfection processes to meet or exceed the strict standards set by the Ontario Ministry of the Environment, Conservation and Parks. Monthly water quality reports consistently show that the water is free from harmful bacteria like E. coli and total coliforms, and levels of lead, sodium, and fluoride remain well within the safe and expected ranges. Visitors often notice that the water has a high mineral content (hardness), typically around 123 mg/L, which can lead to a slight mineral taste but is perfectly healthy to consume. For travelers looking to reduce plastic waste, refilling a reusable bottle from the tap in your hotel or at public fountains is a safe and environmentally friendly practice while exploring the town's historic streets and world-class vineyards.
