Ontario Mold Case Wins: Key Takeaways for Newfoundland and Labrador Tenants

Dealing with mold in your rental home can threaten your health and well-being. Recent high-profile mold case wins in Ontario highlight important lessons for tenants everywhere, including those renting in Newfoundland and Labrador. Understanding your local rights, how to report issues, and what legal precedents mean for you is essential.

Why Ontario Mold Case Wins Matter for Tenants

Ontario courts and tribunals have ruled in favour of tenants when landlords failed to address mold, ordering repairs, compensation, or rent abatements. These outcomes show the importance of documenting problems, knowing your rights, and taking persistent action. While laws differ between provinces, Newfoundland and Labrador tenants can apply similar strategies to protect their health and homes.

Understanding Mold Problems in Rental Homes

Mold is not just unsightly—it can pose real risks to your health, especially for children, seniors, or those with allergies. In Newfoundland and Labrador, landlords must provide and maintain premises that are safe and fit to live in, which includes resolving mold caused by leaks, dampness, or poor ventilation.

  • Common causes: Leaky roofs/windows, plumbing issues, poor ventilation
  • Signs of mold: Musty smell, visible spots on walls/ceilings, increased allergy symptoms
  • Risks: Headaches, coughing, worsened asthma, and other health impacts

These issues fall under broader Health and Safety Issues Every Tenant Should Know When Renting, making it crucial for tenants to act quickly when mold is discovered.

Your Rights and Responsibilities Under Provincial Law

In Newfoundland and Labrador, tenant-landlord relationships are governed by the Residential Tenancies Act, 20181 This law requires landlords to maintain the property in a good state of repair and comply with health, safety, and housing standards set by the province, municipalities, and the fire marshal.

The Residential Tenancies Section handles disputes and questions about rental housing in the province.

Tenants should report mold issues in writing and keep copies for their records. Swift communication and documentation strengthen your case if you need to escalate the matter.

Obligations of Landlords and Tenants

  • Landlords: Responsible for repairs and ensuring the premises are habitable and safe.
  • Tenants: Must keep the property clean and inform the landlord about any problems quickly.

Steps to Take if You Find Mold in Your Rental

If you notice mold, act quickly:

  • Document the problem with photos and dates.
  • Notify your landlord in writing right away. Clearly describe where the mold is and how it affects you.
  • Allow your landlord reasonable time to fix the issue (generally, a few days for serious health hazards).
  • If the landlord does not respond, contact local public health or municipal housing inspectors.
  • If unresolved, you can apply to the Residential Tenancies Section for intervention or dispute resolution.

Persistent tenants in Ontario who carefully followed these steps were more likely to succeed in their claims, serving as a model for others, including those in Newfoundland and Labrador.
