What these findings mean

Health authorities word their violations differently, so we group them by what they mean for food safety. Higher-risk findings are the ones inspectors treat as critical, because they can directly make someone sick.

• Food temperature controlHigher risk

  Bacteria multiply fastest between about 4 °C and 60 °C (40 °F to 140 °F). Inspectors check that cold food stays cold, hot food stays hot, cooked food is cooled quickly, and that staff have accurate thermometers. Temperature problems are one of the most common causes of food poisoning, so these are treated as critical findings.

  Recorded 4 times across 4 separate inspections, most recently on August 21, 2025. For example: Potentially hazardous food is maintained at 4°C (40°F) or lower

• Cleaning and sanitizingHigher risk

  Anything that touches food, such as cutting boards, dishes and utensils, must be washed, rinsed and sanitized. Inspectors check dishwasher temperatures, sanitizer strength and how wiping cloths are stored. Poor sanitizing lets bacteria survive from one use to the next.

  Recorded 3 times across 3 separate inspections, most recently on August 21, 2025. For example: Equipment, utensils, multi-service articles and all food contact surfaces are properly constructed and maintained

• Building, plumbing and upkeepLower risk

  Floors, walls and ceilings must be smooth and clean, with working lighting, ventilation, plumbing, hot and cold water, and washrooms. These are rarely an immediate food-safety risk on their own, but persistent problems can lead to pest or sanitation issues.

  Recorded 4 times across 4 separate inspections, most recently on August 31, 2026. For example: Rooms, walls and ceilings are kept clean, in good repair and in a sanitary condition

• Food safety training and certificationLower risk

  Most jurisdictions require a certified food handler or manager on site, and some require allergen or food-worker training. These findings mean the paperwork or the trained person was missing at the time. They do not by themselves mean food was handled unsafely.

  Recorded 2 times across 2 separate inspections, most recently on August 21, 2025. For example: Records, receipts, certificates maintained as required

• Permits, records and postingLower risk

  Operating permits, required signage, written procedures and logs. These findings are administrative: the documentation was missing or out of date at the time of inspection.

  Recorded once on April 26, 2023. For example: Inspection results are posted in accordance with the Public Health Inspector's request
