Tenant Responsibilities Regarding Mould
While landlords bear the primary responsibility for preventing and resolving mould issues, tenants also have certain responsibilities. Tenants must:
Report any signs of mould to their landlord immediately.
Cooperate with the landlord in accessing the unit for repairs and mould remediation.
Avoid activities that may contribute to mould growth, such as excessive humidity or improper ventilation.
Failing to follow these responsibilities could weaken your case in a dispute with your landlord.
When is the Landlord Responsible for Mould?
In general, a landlord is usually responsible for mould growth that results from:
Defective plumbing or leaks.
Inadequate ventilation.
Poor building design or maintenance.
Failure to respond promptly to tenant complaints.
However, if mould growth is caused by the tenant’s negligence or actions, the landlord may not be held responsible. For example, if a tenant consistently leaves wet towels on the bathroom floor, contributing to excessive moisture, the landlord may argue that the tenant is partly responsible for the mould growth.
What if the Landlord Refuses to Address Mould?
If your landlord fails to address mould issues despite your repeated complaints, you have several options:
Contact the Landlord and Tenant Board (LTB):
The LTB is an independent tribunal that resolves disputes between landlords and tenants in Ontario. You can file an application with the LTB to order your landlord to address the mould issue.
Make Repairs Yourself and Deduct the Costs from Rent:
Ontario law allows tenants to make necessary repairs themselves if the landlord fails to do so within a reasonable time. You can deduct the repair costs from your rent, but you must provide the landlord with proper notice and documentation.
Seek Legal Advice:
If the LTB process proves unsuccessful or if you require more complex legal guidance, consult a lawyer specializing in landlord-tenant law. They can assess your specific situation and advise you on the best course of action.
Conclusion
Mould in rental properties is a serious concern that landlords and tenants must address promptly. Understanding your rights and responsibilities under Ontario law is crucial for protecting your health and ensuring a safe living environment. If you encounter mould in your rental unit, communicate with your landlord, document the issue, and consider seeking legal advice to ensure that your rights are protected. Remember, by working together, landlords and tenants can create a healthy and safe living space for all. [1]
