Ontario Key Deposit Rules: Can landlords keep the key deposit?

Understanding Ontario Key Deposit Rules
When renting a property in Ontario, some landlords may ask tenants to pay a key deposit. This deposit is usually collected to cover the cost of replacing keys, building fobs, or access cards if they are lost.
However, many landlords and tenants are unsure about the rules surrounding key deposits. Questions such as whether landlords can keep the key deposit or use it for other purposes often lead to confusion and disputes.
Understanding the rules can help both landlords and tenants avoid misunderstandings.
Is a Key Deposit Legal in Ontario?
Yes, landlords in Ontario are allowed to collect a key deposit, but only under specific conditions.
According to Ontario rental regulations, a key deposit must:
- Only cover the actual cost of replacing the key, fob, or access device
- Be a reasonable amount
- Be refunded when the tenant returns the keys at the end of the tenancy
For example, if a condominium key fob costs $75 to replace, the key deposit should not exceed that amount.
Can Landlords Keep the Key Deposit?
In most situations, landlords cannot keep the key deposit
If a tenant returns all keys, fobs, or access cards at the end of the tenancy, the landlord should return the key deposit.
The deposit is not intended to be additional income for landlords.
When Can a Landlord Use the Key Deposit?
A landlord may only use the key deposit when keys or access devices are not returned.
Examples include:
- Lost keys
- Missing building fobs
- Damaged access cards that need replacement
In these situations, the landlord may use the deposit to cover the cost of replacing the items.
What Key Deposits Cannot be Used For
A key deposit cannot be used for other expenses related to the rental property.
For example, landlords cannot use a key deposit to cover:
- Property damage
- Cleaning fees
- unpaid rent
- maintenance costs
If disputes arise over these issues, they must be handled through the appropriate legal process.
Avoiding Key Deposit Disputes
Key deposit disagreements are common in rental situations. Both landlords and tenants can reduce disputes by keeping clear records.
Landlords should:
- Charge a reasonable deposit amount
- Clearly document the deposit in the lease agreement
- Return the deposit when the keys are returned
Tenants should:
- Keep records of deposit payments
- Return all keys and access devices when moving out
Final Thoughts
Key deposits are allowed in Ontario, but they are strictly regulated. The deposit must be reasonable, and it can only be used to replace keys or access devices if they are not returned.
Understanding these rules helps landlords remain compliant with Ontario rental laws while protecting tenants from unnecessary charges.
