What these findings mean
Health authorities word their findings differently, so we group them by what they mean for the people in care. Higher-risk findings are the ones that could directly make someone sick, and they matter more here because young children, older adults and people who are unwell are more vulnerable to infection.
Protecting food from contaminationHigher risk
This covers how food and supplies are stored and handled: kept covered, off the floor, and away from anything that could contaminate them. Where food is served, raw meat must be kept away from ready-to-eat food, a direct route for salmonella and E. coli.
Recorded once on January 9, 2026. For example:
Linens are laundered frequently and stored in a sanitary manner
Handwashing and staff hygieneHigher risk
Hand hygiene is the most important way to stop germs spreading between children, residents and staff. Inspectors check that sinks are stocked and easy to reach, that staff wash their hands when required (for example after diapering or before handling food), and that sick staff stay away from work.
Recorded once on January 9, 2026. For example:
Staff follow proper hand hygiene practices
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 2 times across 2 separate inspections, most recently on October 1, 2025. For example:
Floors, walls, ceilings, and carpet are clean and in good repair
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 These findings are administrative: the documentation was missing or out of date at the time of inspection.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 January 9, 2026. For example:
Proper diaper change procedure is followed
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 October 1, 2025. For example:
Surfaces, equipment, furniture are clean and in good repair
