Recreational Water

If you are planning to open or re-open a public recreational water facility (public pool, public cold plunge pool, public floatation pool, hot water pool, public spa/whirlpool, splash/spray pad, wading pool, water slide receiving basin or floatation tank), you are required to notify Public Health at least 14 days before opening by submitting the following form:

Opening Notification Form

Thinking about renting your backyard pool/spa? Using your pool/spa for business/commercial purposes? Please refer to the Ontario Ministry of Health’s Short-Term Residential Swimming Pool Rentals by Private Homeowners guidance. 

Private residential pools and spas that are made available to the public, whether an access fee is charged, are exempt from the Ontario Regulation 565 Public Pools requirements. However, property owners must post specific signage to inform guests and visitors.

To obtain details about the required signage, property owners should contact Region of Waterloo Public Health at 519-575-4400 for more information. In addition, there may be requirements for pools and spas used as recreational water facilities under local municipal by-laws or the Ontario Building Code.

Please contact your home insurance provider for insurance implications and the local municipality for more information.

The Office of the Chief Coroner developed standards for public pools to assist lifeguards and assistant lifeguards in maintaining adequate supervision. These standards require parents or guardians (at least 12 years of age) to assist staff in the supervision of young children.

Children 0-5 years

• Regardless of swimming ability, children may not be admitted unless accompanied by a parent or guardian who is responsible for their direct supervision
• Each parent or guardian can only supervise a maximum of two children at a time

Children 6-9 years

• Non-swimmers must be accompanied by a parent or guardian
  • Each parent or guardian can only supervise a maximum of four children at a time
  • If the children are wearing lifejackets, each parent or guardian can supervise a maximum of eight children at a time
• Children who are swimmers and have passed the facility swim test may be admitted to the swimming pool unaccompanied

Ratios of instructors/lifeguards must follow the Ontario Public Pools Regulation.

Class B pools that do not require a lifeguard still require children under the age of 12 to be accompanied by a parent or guardian. Guardians for Class B pools should be at least 16 years of age. 

The inspector will monitor recreational water including public pools (including hot water pools, cold plunge pools and floatation pools), spas (hot tubs and whirlpools), floatation tanks, splash pads, water slide receiving basins and wading pools.

A public health inspector will check for:

• Operational and sanitation requirements
• Safety equipment
• Lifeguard and supervision requirements
• Water clarity, quality and testing
• Record keeping, and
• Signage

For more information about the regulation, requirements of what public health inspectors look for during an inspection, please review the following resources:

• Public Pools Manual for Owners and Operators
• Public Spas Manual for Owners and Operators
• Recreational Water Reference Document, 2025.

A pool, hot tub, floatation tank, water slide receiving basin, wading pool, or splash pad operator will receive a copy of the inspection report once the inspection is complete. The report will indicate corrective action(s) that is required and a date by which the correction is expected.

A re-inspection may be scheduled to verify that corrective actions have been completed.

If a serious problem is identified during an inspection that poses an immediate health risk to the client or the provider, the facility may be ordered to close until corrective action is taken and the health risk has been eliminated.

Public spa and pool operators can print these templates for record keeping purposes. Included in each template is a daily records log, water chemistry tests, and monthly tests.
