What these findings mean

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

• Cleaning and sanitizingHigher risk

  Surfaces, dishes and tools that touch food or people must be cleaned and then sanitized or disinfected. Inspectors check sanitizer strength, dishwasher temperatures and how cleaning is done. Poor sanitizing lets germs survive from one use to the next.

  Recorded once on September 24, 2026. For example: Equipment, utensils, multi-service articles and all food contact surfaces are properly constructed and maintained

• Chemicals and toxic substancesHigher risk

  Cleaning products, disinfectants and pesticides must be labelled and stored safely, away from food and from surfaces people touch. Inspectors flag chemicals that could contaminate food or harm people, as well as pest treatments applied without proper supervision.

  Recorded once on November 3, 2025. For example: Chemicals and medications are stored / locked in a safe manner

• 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 once on October 2, 2024. For example: Mechanical dishwashing: Wash / rinse water clean, water temperature, timing cycles, sanitizer

• Building, plumbing and upkeepLower risk

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

  Recorded 3 times across 3 separate inspections, most recently on March 17, 2026. For example: Toys are maintained in a clean and sanitary condition

• Equipment and utensilsLower risk

  Equipment has to be made of cleanable materials, kept in good repair and stored properly. These findings are mostly about upkeep, like a cracked surface or worn part. They are generally lower risk but show how well the place is maintained.

  Recorded once on August 25, 2025. For example: Furniture, equipment and appliances in food handling and storage rooms arranged and constructed to permit a clean and sanitary environment
