What these findings mean

Health authorities word their findings differently, so we group them by what they mean for the people using the facility. Higher-risk findings are the ones that could directly cause illness or injury, such as water that is not properly treated.

• Pool and spa water qualityHigher risk

  For pools, spas and splash pads, inspectors test disinfectant levels, pH and water clarity, and check safety equipment. Water that is not properly treated can spread skin, ear and stomach infections.

  Recorded 2 times across 2 separate inspections, most recently on June 23, 2026. For example: Total alkalinity is within required range

• Chemicals and toxic substancesHigher risk

  Pool chemicals such as chlorine and acid must be labelled, stored apart from each other and handled safely. Mixing them by mistake can release toxic gas, so storage and handling problems are treated seriously.

  Recorded once on June 9, 2025. For example: Chemical feeder is provided to administer chlorine, chlorine compound or a bromine compound

• Building, plumbing and upkeepLower risk

  Decks, ladders, fencing, drains, washrooms and signage must be in good repair. Damaged drain covers or broken fencing can be real safety hazards, while most other upkeep issues are lower risk.

  Recorded once on June 9, 2025. For example: Water outlet covers are present, secure and in good repair

• Other findingsLower risk

  Findings that do not fit the categories above, such as follow-ups that confirm an earlier violation was corrected, or requirements specific to this type of facility.

  Recorded 2 times across 2 separate inspections, most recently on December 15, 2025. For example: Clock installed in a conspicuous location
