About the Recreational Water Program

Public Health Inspectors inspect public pools, spas, wading pools, spray/splash pads and receiving basins (Class C facilities) to reduce the possibility of injuries and waterborne illness related to recreational water facilities. Compliance inspections of recreational water facilities are carried out in accordance with the Ontario Public Pools Regulation 565/90.

The Ontario Public Pools Regulation 565/90 (external link) applies to the following public recreational water facilities:

  1. Class A and Class B public pools
  2. Public spas
  3. Class C facilities (public wading pools, public splash pads/spray pads, and water slide receiving basins).
