Dangerous Health Risks of Mold Exposure in Toronto Homes (2025)
According to Health Canada and Toronto Public Health, prolonged exposure to indoor mold can trigger:
- Severe allergic reactions and chronic sinus infections
- Worsening asthma and new cases in children
- Skin rashes, eye irritation, and persistent cough
- Fatigue, headaches, and cognitive issues (“brain fog”)
- Immune system suppression – especially dangerous for seniors, infants, and chemotherapy patients
Toronto Public Health reported a 40% increase in mold-related emergency visits since 2020, largely due to aging rental stock and delayed maintenance.

- High indoor humidity from sealed energy-efficient windows
- Flooding and sewer backups from Toronto’s increasingly extreme rain events
