What the Law Says
RTA s.105: A landlord can only collect last month's rent deposit. All other deposits are illegal.
RTA s.106: Landlord must pay interest on last month's rent at the Bank of Canada annual rate, payable annually.
What This Means
Damage deposits are illegal in Ontario. Your landlord cannot charge a "damage deposit" or "security deposit" for damage to the unit.
You can recover all illegal deposits plus interest. You can also file a T1 at the LTB to force return of deposits and claim compensation.
Real Example
A landlord in Hamilton charged a tenant $2,000 last month's rent + $800 "damage deposit" + $300 "key deposit" = $3,100 total. The tenant paid and moved in. The tenant filed a T1 claiming the $1,100 in damage and key deposits were illegal. The LTB ordered the landlord to return $1,100 plus interest and awarded the tenant $500 in compensation for the illegal charges.
What You Can Do
If landlord collected illegal deposits:
- Calculate: last month's rent only is legal
- Identify: any damage deposit or key deposit is illegal
- Request: write to landlord asking for return
- Document: save all receipts and communications
- File T1: at the LTB to recover money + interest
What the Law Says
RTA ss.105-106 are among the most frequently violated sections because landlords often collect illegal deposits and tenants don't know they can recover them.
RTA s.105(1): "A landlord may collect a deposit ... if the deposit is the amount of rent payable by the tenant for the last month of the tenancy."
RTA s.105(2): "No landlord shall ... demand or collect a deposit, including a damage deposit, unless the deposit is the last month's rent."
RTA s.106: "A landlord shall pay interest ... at the rate set by the Board [annually, currently matching Bank of Canada prime rate]."
Key principle: A landlord's only right is to collect one month's rent in advance. Everything else is illegal.
Legal vs Illegal Deposits
Legal Deposit (Only)
- Last month's rent: Equivalent to one month's rent (the exact amount of the rent for a normal month)
- Held in trust: Landlord must hold it separately and use it only for the last month's rent
- Interest paid: Landlord must pay annual interest at Bank of Canada rate
Illegal Deposits (All Forbidden)
- Damage deposit: Any deposit labeled for wear and tear, damage, cleaning, etc.
- Key deposit: Deposit for replacement of lost keys
- Security deposit: Any amount for "security"
- Cleaning deposit: Deposit for end-of-lease cleaning
- Pet deposit: Extra deposit if you have a pet
- Parking deposit: Deposit if parking is provided
- Admin or application fees: Some fees are illegal if they're deposits
Gray Area: Admin Fees vs Deposits
Legitimate admin fees: Some one-time administrative charges for processing application may be legal if not called a deposit and actually cover admin costs (e.g., $50 application processing fee).
Illegal deposits disguised as fees:A "$300 damage deposit" called an "admin fee" is still a deposit and illegal.
If unsure, consult a legal clinic or file a T1.
Damage Deposits Are ILLEGAL in Ontario
This Is Important
In some provinces or countries, damage deposits are standard. In Ontario, they are explicitly forbidden. Period.
Why No Damage Deposits?
Ontario law assumes tenants will cause normal wear and tear. The landlord cannot charge for this. Instead:
- If there is damage beyond normal wear, the landlord can pursue the tenant in court (small claims court)
- The landlord cannot pre-collect money for potential future damage
- Damage must be documented and the tenant has the right to dispute it
Normal Wear and Tear vs Damage
Normal wear and tear (NOT damage):
- Scuff marks on walls from living
- Minor paint fading from sunlight
- Worn carpet from normal use
- Small nail holes for pictures
- Worn grout between tiles
Actual damage (can be charged):
- Large holes in walls
- Broken windows not from normal use
- Stains from pet accidents (if pet not allowed)
- Broken fixtures beyond wear and tear
Key Deposit (Illegal)
What Is a Key Deposit?
A key deposit (also called a "key fee") is an amount charged for replacement of lost or unreturned keys. This is illegal under RTA s.105.
Why It's Illegal
A key deposit is not "last month's rent." It's a contingent charge for potential future damage/loss. This falls squarely under the prohibition on collecting deposits for anything other than last month's rent.
What Landlord Can Actually Do About Keys
If a tenant loses keys or doesn't return them:
- Landlord can charge reasonable cost of re-keying locks (must be actual cost, not inflated)
- This is NOT a "deposit" — it's a charge for actual expense incurred
- Landlord can only charge after the tenant has left and the damage is known
- Tenant can dispute the charge if unreasonable
If Charged a Key Deposit
- Know it's illegal — demand return from landlord
- Document the amount and when charged
- Keep proof of payment (receipt, bank statement)
- If landlord refuses, file T1 to recover
Last Month's Rent Rules
What Last Month's Rent Is
"Last month's rent" is the amount of one month's rent, held by the landlord and applied to your final month of tenancy.
Example: You agree to pay $1,500/month. At the start, you pay:
- First month's rent: $1,500
- Last month's rent deposit: $1,500
- Total move-in cost: $3,000
Using Last Month's Rent
When you leave, the last month's rent deposit is applied to your final month:
- You do not pay rent for your final month (the deposit covers it)
- If there's damage or rent owed, landlord deducts from the deposit (in writing)
- Landlord must return any excess within 30 days of you vacating
If Rent Increases
If your rent goes up during tenancy, what about the deposit?
Rule: Last month's rent deposit is based on the rent at the time of the tenancy start, NOT the final rent amount.
Example: You start at $1,500/month, deposit $1,500. After 2 years, rent is $1,600/month (legal increase). When you leave, your last month is covered by the $1,500 deposit. You owe the difference ($100) for that final month.
Common Violations
- Not returned on vacating: Landlord keeps last month's rent and charges for damages (should return excess after deducting documented damages)
- Held without interest: Landlord keeps deposit for 2+ years without paying interest
- Increases with rent: Landlord demands higher deposit when rent increases
- Kept for "general" damages: Landlord deducts without itemizing or without giving you chance to dispute
Interest on Last Month's Rent
Legal Requirement
RTA s.106 requires landlords to pay interest on last month's rent annually at the Bank of Canada annual rate.
Current Interest Rate
For 2025, the prescribed rate is set by Ontario regulation. Check Ontario.ca or ask your legal clinic for the current rate (typically 1-4% depending on economic conditions).
How Interest Is Calculated
Example: Last month's rent deposit: $1,500. Rate: 2.5% (2025). Interest owed annually:
$1,500 × 0.025 = $37.50 per year
When Interest Must Be Paid
RTA s.106: "The interest shall be credited to the tenant on the anniversary of the day on which the deposit was taken."
- Annually: On each anniversary of when you paid the deposit
- How paid: Either added to the deposit (so you get more back at the end) or paid to you directly
- If not paid: Tenant can claim it, with consequences for landlord
If Landlord Doesn't Pay Interest
Many landlords forget or refuse to pay interest. You can:
- Calculate interest owed (annual rate × number of years × deposit amount)
- Request payment from landlord (in writing, citing RTA s.106)
- If landlord refuses, file T1 to recover interest
- At the LTB, you will be awarded the interest plus compensation
Getting Your Deposit Back
When Vacating
- Final month: You don't pay rent; the deposit covers it
- Move-out inspection: Landlord may inspect and document any damage
- Itemized deductions: Landlord must provide written list of any damages deducted, with costs
- Return within 30 days: RTA requires return of any excess within 30 days of move-out
Common Problems
- No itemized list: Landlord doesn't provide details of what was deducted
- Inflated charges: Landlord charges excessive amounts for repairs or cleaning
- Deducting normal wear: Charging for paint, worn carpet, or normal scuffs
- Late return: Money not returned within 30 days
- No interest paid: Deposit returned without annual interest accrued
What to Do If Deposit Isn't Returned
- Request payment in writing (email, certified mail) citing RTA s.105-106
- Set a deadline (e.g., "Please return by [date]")
- If landlord responds with itemized deductions, review and dispute if unreasonable (normal wear vs damage)
- File T1 at LTB if deposit isn't returned or if deductions are unjustified
Documentation to Keep
- Receipt or proof of payment (lease, bank statement)
- Move-in photos (if you took them)
- Move-out inspection report (if provided by landlord)
- Any written communication about deductions or return
- Quotes from contractors showing reasonable repair costs
Filing T1 Application
