About Thunder Bay's drinking water

The City of Thunder Bay Water Authority’s top priority is to maintain a safe and sustainable supply of water for the citizens of Thunder Bay.

See the 2024 Drinking Water Quality Annual Report.  

In the City of Thunder Bay, our drinking water comes from Lake Superior. Raw water taken directly from the lake is not suitable for drinking. We must treat it to meet Ontario’s drinking water regulations. The location and depth of the intake at the Plant makes our water quality stable for a long time. At the Bare Point Water Treatment Plant on Lakeshore Drive:

  • We draw water from its source;
  • Pass it through a screening process;
  • Filter it through the Zeeweed membrane filtration system; and
  • Disinfect and then transport it through the City’s extensive water supply system.

Water is then delivered to us from the Plant. This ensures a safe water supply for the City’s water consumers. Learn how we protect our water to ensure that it’s safe to use.

Changes to our drinking water

Water filters for homes with lead service pipes:

The City has identified properties with lead water service pipes. In the last two years, properties received free water filter kits consisting of a NSF/ANSI-53 approved PUR – Ultimate Filtration System with Lead Reduction water filters to eliminate the risk of consuming lead while drinking tap water.

To reduce the risk of consuming lead while drinking tap water at this time, properties that have been identified with a known lead service pipe will now receive a Brita® Tahoe Water Pitcher with a total of two (2) Brita® Elite™ water filters, which for an average household is a 12-month supply of NSF/ANSI-53 approved lead-reducing filters at no cost.  Additional filters can be purchased at a variety of local retailers.  

Lead found in drinking water can pose a significant health risk. The population at the highest risk from lead exposure are infants, children under the age of 6, and pregnant women.

If you recently purchased your home, and/or are unsure if you may have a lead service pipe, please call City Dispatch at 807-625-2195  

Users must follow the manufacturer’s owner’s manual that provides instructions on how to use the pitcher and filters. These water filters are certified to reduce lead in tap water and should be used for drinking, cooking, and preparing baby formula. It is important to use these filters as lead in drinking water can pose health risks, especially for infants, children under the age of six, and pregnant women.

Requirements for drinking water

The City’s Municipal Drinking Water Works Licence, in conjunction with Ontario's Safe Drinking Water Act and associated regulations, sets stringent monitoring requirements for drinking water. The City employs a certified Laboratory for its drinking water testing. The results of this monitoring process are available in the latest of the City of Thunder Bay’s Drinking Water Quality Annual Report, prepared as required by Ontario Reg.170/03 Drinking Water Systems.

The City strives to protect our drinking water and provide you with quality water through source water protection, backflow prevention, and quality control.

If your home was built prior to the mid 1950s, you may have a lead service pipe. See our Lead in Drinking Water webpage and learn how you can protect yourself. 

For more information on the Safe Drinking Water Act, 2002, see Ontario Regulation 170/03 (Drinking Water Systems).

Water fill stations

Thunder Bay Sewer & Water Services operates and maintains two residential Water Fill Stations (tap houses) to provide rural Thunder Bay residents with potable water. We also operate and maintain one fill station for commercial use only. 

Pre-paid fob

The City’s residential and commercial Water Fill Stations use a fob system. In order to dispense water, you need to purchase a fob. A $26 deposit (effective February 1, 2024) is required when you purchase your fob. Lost or damaged fobs will not be refunded.

Corrosion Control Plan

In accordance with Ministry of the Environment, Conservation and Parks regulations (formerly Ministry of Environment and Climate Change), the City developed the Corrosion Control Plan to reduce lead levels at the tap. This approved plan is currently under review; short-term measures have been put in place. Customers will be notified of any changes to the drinking water.
