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.

• Protecting food from contaminationHigher risk

  This covers how food is stored, prepared and displayed: raw meat kept away from ready-to-eat food, food covered and stored off the floor, and nothing dripping or splashing into it. Cross-contamination from raw to cooked food is a direct route for salmonella and E. coli.

  Recorded 4 times across 3 separate inspections, most recently on April 15, 2024. For example: Floors, walls, and ceilings clean and in good repair and maintained in a sanitary manner

• 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 2 times across 2 separate inspections, most recently on April 5, 2023. For example: Mechanical dishwashing: Wash / rinse water clean, water temperature, timing cycles, sanitizer

• Chemicals and toxic substancesHigher risk

  Cleaning products, sanitizers and pesticides must be labelled and stored away from food and food-contact surfaces. Inspectors flag chemicals that could end up in food, as well as pest treatments applied without proper supervision.

  Recorded once on December 8, 2023. For example: Toxic or poisonous substances required for maintenance in food premises are stored and handled as prescribed in the regulation

• 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 2 times across 2 separate inspections, most recently on December 8, 2023. For example: Garbage and waste (solid or liquid) collected and removed to ensure sanitary condition of premise
