Security deposit rules are among the most confusing aspects of Canadian rental law because they vary so significantly by province. In Ontario, landlords can only take one month's rent as a last month's rent deposit — a damage deposit is prohibited. In BC and Alberta, a damage deposit is permitted but capped. In Quebec, no deposit of any kind is permitted. Knowing your province's rules before you pay any deposit is essential.
What is a Security Deposit?
A security deposit (or damage deposit) is a sum paid by a tenant at the start of a tenancy, held by the landlord against unpaid rent or damage beyond normal wear and tear. The rules on how much can be charged, how it must be held (in a trust account or otherwise), whether interest must be paid, and how it must be returned all differ by province. Some provinces prohibit damage deposits entirely and rely only on last month's rent deposits. The key principle across all provinces: the deposit must be returned unless the landlord can evidence a legitimate deduction.
Red flags to watch for
In BC, the damage deposit cap is half a month's rent. In Alberta, one month's rent. In Ontario, no damage deposit is permitted at all — only last month's rent. A deposit above the cap is unlawful.
Ontario's Residential Tenancies Act 2006 (s.105) prohibits damage deposits. Only last month's rent (which must be held and applied as rent, not held as damage security) is permitted. Any other deposit is void.
Without a documented move-in inspection, you have no baseline against which to dispute deductions at the end of the tenancy. Both you and the landlord should sign a condition report at the start.
You are responsible only for damage beyond normal wear and tear — not for the general ageing of fixtures and fittings. Clauses that purport to deduct for all 'damage' without this qualification give landlords too broad a right to make deductions.
Most provinces specify a timeline for returning the deposit (e.g., 10 days in BC; 10 business days in Alberta). If the lease doesn't acknowledge this, that is worth flagging.
Your legal rights
Security deposit rules by province: Ontario — damage deposits prohibited; only last month's rent permitted (RTA 2006, s.105). BC — damage deposit capped at half month's rent, must be held in trust; interest payable; return within 15 days or with itemised deductions within 30 days (RTA 2002). Alberta — damage deposit capped at one month's rent; interest payable on deposits held 6+ months; return within 10 days (RTA 2000). Quebec — no deposits of any kind permitted (Civil Code Art. 1904). Manitoba — security deposit capped at half month's rent; held in trust by Residential Tenancies Branch (RTA 2010). Disputes go to the relevant provincial tribunal.
Questions to ask before you sign
- 1What is the deposit amount, and does it comply with my province's cap?
- 2Is this a damage deposit, a last month's rent deposit, or both — and are both permitted in my province?
- 3How is the deposit held — in a separate trust account, with the Residential Tenancies Branch, or by the landlord directly?
- 4Will there be a move-in condition report documenting the property's state at the start of the tenancy?
- 5Within what timeframe must the deposit be returned at the end of the tenancy, and under what conditions can deductions be made?
