Security deposit rules are one of the most misunderstood areas of Canadian landlord law — and one of the most expensive to get wrong. Collect a deposit that's not permitted in your province and you're in violation before the tenant even moves in. Miss the return deadline in British Columbia and you owe double. Try to use Ontario's last month's rent deposit for damage repairs and you'll face a Landlord and Tenant Board application.
The rules don't just vary — in some cases they're the opposite of what landlords assume. This guide covers what each major province actually allows, sourced directly from the governing legislation and enforcement bodies.

Ontario: No Damage Deposits — Ever
Ontario is the province where landlords are most likely to make a costly mistake on deposits, because the rules are counterintuitive to anyone who has rented in another province or country.
What you can collect: Only a last month's rent (LMR) deposit — equal to one month's rent for monthly tenants, or one week's rent for weekly tenants. This is codified in sections 105–106 of the Residential Tenancies Act, 2006.
What you cannot collect: Damage deposits, pet deposits, key deposits, cleaning deposits — any deposit intended to cover potential damage or costs beyond rent is prohibited outright in Ontario. There are no exceptions.
How it must be used: The LMR deposit can only ever be applied to the final rent period before the tenant vacates. It cannot be used for damage repairs, unpaid utilities, cleaning costs, or anything else. If your tenant causes damage, your only recourse is an application to the Landlord and Tenant Board for a damage order — the LMR deposit cannot offset it.
Interest obligation: Ontario landlords must pay annual interest on the LMR deposit at the provincial rent increase guideline rate. The rate is 2.5% for 2025 and 2.1% for 2026. Interest is typically credited against rent rather than paid in cash — most landlords apply it when the tenant uses the deposit for their last month. Failing to pay or credit accumulated interest gives tenants grounds for an LTB application.
“The rent deposit can only be used as the rent payment for the last month or week before the tenant moves out. It cannot be used for anything else, such as repairing damage to the rental unit.” — Tribunals Ontario, LTB Guide to the RTA

British Columbia: Strict Deadlines and a Double-Deposit Penalty
BC has the most detailed deposit rules in Canada — and the harshest penalty for non-compliance. The Residential Tenancy Branch (RTB) enforces these rules under the Residential Tenancy Act.
What you can collect: A security deposit of up to half a month's rent. Separately, if you allow pets, you may collect a pet damage deposit of up to half a month's rent. If you collect both, the combined total cannot exceed one full month's rent. One pet damage deposit covers all pets regardless of number — you cannot charge per animal.
Return deadline: You have 15 days from the later of (a) the tenancy end date or (b) receipt of the tenant's written forwarding address. This “later of” rule matters — if a tenant doesn't provide a forwarding address, the 15-day clock doesn't start.
The double-deposit penalty: Miss the 15-day deadline without filing for RTB dispute resolution and you owe the tenant double the original deposit amount. Interest is calculated on the original amount only and is not doubled. This is one of the most severe landlord penalties in Canadian tenancy law.
What you can deduct: Unpaid rent and damages beyond normal wear and tear. You cannot retain any portion of the deposit without either (a) written agreement from the tenant, or (b) an official RTB arbitration order. You cannot simply keep the money and send an invoice.
The inspection requirement: BC landlords who fail to offer the tenant at least two move-in and move-out condition inspection opportunities, or fail to provide the tenant with a signed copy of the inspection report, lose their right to claim against the deposit for damage entirely. This rule catches many landlords off guard — the inspection isn't optional if you intend to make any deduction.
Interest obligation: BC deposit interest is calculated using a formula of 4.5% below the province's prime lending rate on January 1 of each year. The rate was 0.95% for 2025 and is 0% for 2026 (because the prime rate fell below 4.5%). The RTB provides an online deposit interest calculator.

Alberta: One Month Maximum, 10-Day Return Window
Alberta permits a true security deposit — unlike Ontario, it can be applied to damage claims at the end of the tenancy. The rules are governed by the Residential Tenancies Act, SA 2004 (s. 43).
What you can collect: A security deposit of up to one month's rent. Unlike BC, there is no separate pet damage deposit category — if you allow pets, the single deposit is your protection. You cannot collect additional deposits beyond one month's rent regardless of the circumstances.
How it must be held: Alberta landlords are required to hold security deposits in an interest-bearing trust account, separate from personal or business funds. This is a legal obligation, not optional.
Return deadline: Deposits must be returned within 10 days of the tenant giving up possession of the unit. If deductions are being made but final repair costs aren't known, a written itemized estimate must still be provided within 10 days, with a final statement to follow within 30 days. Missing these windows can affect your ability to make deductions legally.
What you can deduct: Unpaid rent and damages beyond normal wear and tear. You must provide an itemized written statement listing the damage, the repair cost, and supporting receipts. “General damage” without specifics is not sufficient.
Interest obligation: Alberta interest rates are set annually using ATB Financial's one-year GIC rate from November 1 of the prior year, minus 3 percentage points. When that rate is 3% or below, the deposit interest rate for the following year is 0%. Rates: 2024 was 1.6%, 2025 is 0.5%, and 2026 is 0%. Interest is calculated annually and must be paid or credited to the tenant.

Quebec: Deposits Are Prohibited
Quebec is the only province in Canada where security deposits are not merely restricted — they are prohibited. Article 1904 of the Civil Code of Québec prohibits landlords from requiring any payment beyond the first rent period. This applies to damage deposits, pet deposits, key deposits, and any other form of upfront security.
A landlord who demands a deposit in Quebec is in violation of the Civil Code. A tenant who pays one can legally demand it back immediately. There is a narrow carve-out where a tenant may voluntarily propose a deposit arrangement — but landlords have no power to require, request, or pressure one.
This makes Quebec meaningfully different from every other province. Quebec landlords who want protection against damage must rely entirely on the Tribunal administratif du logement (TAL) after the fact.

Other Provinces at a Glance
Manitoba
Manitoba allows a security deposit of up to half a month's rent under the Residential Tenancies Act. Deposits must be returned within 14 days of tenancy end. The Residential Tenancies Branch (RTB) handles disputes. Manitoba also requires interest on deposits — landlords should check the current annual rate with the RTB.
Saskatchewan
Saskatchewan permits a security deposit of up to one month's rent under the Residential Tenancies Act. If no deductions are being made, the deposit must be returned within 7 business days. If deductions apply, a written statement must be provided within 30 days. The Office of Residential Tenancies (ORT) handles disputes.
Nova Scotia
Nova Scotia allows a security deposit of up to half a month's rent under the Residential Tenancies Act. The return deadline is 10 business days after the tenancy ends. The Director of Residential Tenancies handles disputes.
New Brunswick
New Brunswick allows a security deposit of up to one month's rent under the Residential Tenancies Act. The deposit must be returned within 7 days of tenancy end if there are no deductions. The Rentalsman handles disputes and is the provincial enforcement body.
What Counts as “Normal Wear and Tear”?
Every province uses some version of “damages beyond normal wear and tear” as the standard for permissible deductions — but few define it precisely. In practice, the distinction matters enormously at dispute resolution.
Normal wear and tear (cannot deduct): Small nail holes from picture hanging, minor scuffs on walls from furniture, carpet worn from normal foot traffic over years, faded paint from sun exposure, minor scratches on hardwood.
Damages beyond normal wear and tear (can deduct): Large holes in walls, stains from spills or pet accidents, broken fixtures, deep gouges in flooring, unauthorized alterations, excessive cleaning required beyond standard move-out cleaning.
The longer the tenancy, the more wear and tear is expected. A tenant who lived in a unit for 5 years is not responsible for repainting — paint has a useful life, and that life has likely expired. Adjudicators and arbitrators across Canada consistently apply the principle that deposits compensate for premature damage, not normal aging of the unit.
The Inspection Obligation: Don't Lose Your Right to Deduct
Most provinces require a move-in and move-out condition inspection to preserve a landlord's right to make damage deductions. In BC, this is strictly enforced — failing to complete proper inspections extinguishes your right to claim against the deposit, regardless of how severe the damage is.
Best practice across all provinces:
Move-in inspection: Walk through the unit with the tenant before move-in, document every existing mark, scratch, stain, or issue in writing, and have both parties sign. Photographs with timestamps are essential — they are the primary evidence in deposit disputes.
Move-out inspection: Offer the tenant the opportunity to attend and document the unit's condition again at move-out. Compare against the move-in report. Any damage that appears on the move-out report but not on the move-in report is potentially chargeable — subject to wear and tear standards.
Landlords who skip this process consistently lose deposit disputes. Adjudicators across Canada are skeptical of damage claims without documented proof that the condition existed at move-out and didn't exist at move-in.
Tracking Security Deposits for Tax Purposes
Security deposits are not income when received — they are a liability until applied. In Ontario, the LMR deposit becomes income in the final month when it is applied to rent. In provinces with true security deposits, the deposit becomes income only to the extent it is retained for damages or unpaid rent at the end of the tenancy.
For CRA purposes:
Record the deposit received with the date and amount, tied to the specific tenancy. It sits as a liability on your books until the tenancy ends.
When the tenancy ends, record the disposition: returned in full (no income), applied to last month's rent (rental income), or retained for damages (other income, reportable in the year retained, deductible against actual repair costs).
Interest paid on deposits is a deductible rental expense in the year it is paid or credited.
Proper deposit tracking also matters for PIPEDA and provincial privacy obligations — tenant financial records must be maintained securely and retained for the required period.
The Bottom Line for Canadian Landlords
The most important things to know, regardless of province:
Know your province's rules before collecting anything. Collecting a prohibited deposit is a violation even if the tenant agrees to pay it — the law protects tenants against illegal deposit demands, and agreeing doesn't make it legal.
Document the unit condition meticulously. Photographs at move-in and move-out, signed inspection reports, and timestamped evidence are the difference between winning and losing a deposit dispute.
Return deposits on time. The return deadlines are strict. In BC especially, missing the 15-day window costs you double. Set a calendar reminder the day a tenant gives notice.
Keep deposit funds separate. In Alberta (and as best practice everywhere), deposits must not be commingled with your operating funds. Use a dedicated account or track them precisely in your rental management records.
Interest is your obligation. Ontario, BC, and Alberta all require annual interest on deposits. The rates are low right now, but the obligation exists and failing to pay it is a violation that tenants can act on at the tribunal.
