Recreational Water Operators

Public health inspectors check each public pool, public spa, wading pool, and splash pad in Huron County to make sure the facilities are following regulations and guidelines for water treatment and safety. This helps prevent illness from swimming in contaminated water.

Public health inspectors inspect indoor pools and spas every three months, and outdoor pools and spas at least twice a year. Wading pools, splash pads and spray pads are inspected at least once per year.

NEW: Changes to Ontario Regulation 565: Public Pools

Ontario Regulation 565: Public Pools (O. Reg. 565) has been amended to include requirements for public pools, public spas, and Class C facilities. This amended regulation comes into effect July 1, 2018.

A Class C facility is any of the following:

  • A public wading pool
  • A public spray pad or public splash pad
  • A water slide receiving basin that serves solely as a receiving basin for persons at the bottom of a water slide.

Key changes include:

Notification of Opening

Anyone opening a pool, spa or wading pool in Huron County must notify, in writing, the Huron County medical officer of health or a public health inspector with the Huron County Health Unit.

If a pool, spa or wading pool has been closed for more than 4 weeks and will re-open, then the facility owner must notify the health unit of their intent to open and arrange an inspection. The following information is required:

  • date that the facility is to be opened or re-opened
  • the name and address of the operator
  • whether the facility is a class A, B or C facility or spa.

If the recreational facility is closed due to construction, then the owner must also provide, in writing, the building permit number issued. The owner must also state in writing, whether or not all preparations needed to operate the facility in accordance with the regulation have been completed.

Admission Standards for Class A pools (guardian supervision of children under 10)

Class A pools are now required to have a process in place ensuring guardian supervision of children under 10 years of age. This process must include a swim test. Pool operators are encouraged to continue using existing admission policies that meet the regulatory requirements such as those recommended by the Chief Coroner of Ontario; or consult with industry experts on best practices (e.g. swim tests) to meet the requirements of the regulation at their facility.

Daily inspection and recording frequencies

The daily inspection and recording frequencies for water parameters and water clarity are now the same for pool, spa, wading pool and splash/spray pad operators. Every operator of a public pool, spa, wading pool, splash/spray pad must test and record total alkalinity, pH, free available chlorine, total chlorine or bromine residual and water clarity at a minimum of 30 minutes prior to opening, and every 2 hours until the daily use period has ended. If the pool, spa, wading pool or splash/spray pad has an automatic sensing device, these parameters must be tested and recorded 30 minutes prior to opening, and every 4 hours until the daily use period has ended. Use log books to record these requirements.

  • sterile gauze pads, each 75 millimetres square
  • 50 millimetre gauze bandages
