Official record from Alberta →

Inspection summary

O'Neil Tower - Swimming Pool has been inspected 9 times by Alberta Health Services (Environmental Public Health) since July 19, 2024. The most recent inspection, on September 9, 2026, recorded 5 infractions.

None of the 9 inspections on record were free of infractions. In the past 12 months there were 3 inspections with 13 infractions recorded. The higher-risk findings here relate to: Pool and spa water quality, Food temperature control and Chemicals and toxic substances.

Recent inspections have recorded more infractions than earlier ones, so it is worth reading the latest reports closely.

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 17 times across 9 separate inspections, most recently on September 9, 2026. For example: Is the bacteriological quality of the water in this pool satisfactory (Non-Critical)?

  • Food temperature controlHigher risk

    Inspectors check that anything that has to be kept at a set temperature, such as chilled or hot food, or equipment like sterilizers, stays in its safe range and that accurate thermometers are on hand. With food, temperature problems are one of the most common causes of food poisoning.

    Recorded 2 times across 2 separate inspections, most recently on July 26, 2024. For example: Is the pool maintained in a clean and sanitary condition, good repair and are temperatures being properly regulated?

  • 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 September 3, 2025. For example: Is the chemical quality of the water in this pool satisfactory (Critical)?

  • 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 10 times across 7 separate inspections, most recently on September 9, 2026. For example: Does the pool have adequate written policies, plans and posted rules and safety information to ensure that the pool is operating in a safe manner?
