1. About Toxic Mold Law in Ontario, Canada

Toxic mold issues in Ontario are addressed through general housing, health and safety laws rather than a mold-specific statute. Tenants and landlords rely on the Residential Tenancies Act to demand repairs and safe living conditions. Homeowners and builders rely on building codes and common law for construction defects and moisture control. Workplace mold exposure falls under occupational health and safety regulations.

Mold related disputes often involve several overlapping legal avenues. These include tenancy protections, building standards, health and safety obligations, and, where relevant, human rights considerations. Mold presence can implicate health, property value, and environmental concerns, making careful legal counsel important.

Indoor dampness and mold are linked to respiratory symptoms and asthma, especially for children and sensitive individuals.

The Residential Tenancies Act, the Ontario Building Code and related regulations are central to mold related matters in rental, construction, and workplace contexts.
