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 15, 2026. For example:
pH is within range of 7.2 to 7.8.
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 2 times across 2 separate inspections, most recently on August 13, 2026. For example:
Daily records are kept and signed each operating day.
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 once on August 13, 2026. For example:
Pool notices contain required information and displayed in correct places.
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 September 5, 2025. For example:
Facility is kept clean, free from slipperiness and disinfected, free of hazardous obstructions and ventilated to remove odours.
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.
