None of the 9 inspections on record were free of infractions. In the past 12 months there were 6 inspections with 23 infractions recorded. The higher-risk findings here relate to: Pool and spa water quality and Chemicals and toxic substances.

Recent inspections have recorded fewer infractions than earlier ones, so the record is improving.

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 13 times across 7 separate inspections, most recently on August 21, 2026. For example: Stabilized free available chlorine (FAC) within range of 1 ppm to 10 ppm.

  • 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 8, 2026. For example: Chemical feeder is used to administer chlorine, chlorine compound or bromine.

  • Permits, records and postingLower risk

    Operating permits, water-test logs, posted bather rules and emergency procedures. Daily test logs are how operators show the water was checked and treated between inspections.

    Recorded 10 times across 7 separate inspections, most recently on August 21, 2026. For example: Operator trained in the operation and maintenance, filtration systems, water chemistry and relevant safety and emergency procedures.

  • 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 6 times across 5 separate inspections, most recently on August 21, 2026. For example: Premises is operated and maintained free from conditions that may be an immediate health hazard.

  • Food safety training and certificationLower risk

    Many jurisdictions require trained pool operators and certified lifeguards. These findings mean required training, certification or staffing records were missing at the time of inspection.

    Recorded 3 times across 3 separate inspections, most recently on June 8, 2026. For example: Pool notices contain required information and displayed in correct places.
