Ontario Rental Deposit Rules & Calculator
Ontario generally caps the rent deposit at one rental period.
Calculate the standard maximum
This models the standard rule summarized by the official source below. Special tenancy types, pets, keys or other permitted charges can follow different rules.
The rule in plain English
For a monthly tenancy, Ontario allows a rent deposit up to one month of rent. It is applied to the final rental period and is not a general damage deposit.
The landlord may also collect the first month of rent when it is due, so a renter can need roughly two months of rent at move-in: first month plus the permitted last-month rent deposit.
What renters should verify before paying
- The rent deposit is for the last rental period, not ordinary damage.
- Key deposits have separate rules and must be reasonable.
- Interest rules can apply to rent deposits.
A landlord asking for money does not by itself establish that the payment is permitted. Ask what the payment is for, get the amount and purpose in writing, and keep proof of payment. This is especially important for newcomers who may be unfamiliar with local tenancy rules and may feel pressure to secure housing quickly.
Why this rule matters to your move-in budget
The deposit changes how much cash you need before move-in. At $2,000 monthly rent, a one-month deposit means another $2,000 upfront; a half-month cap means $1,000; and a rule that prohibits an additional security deposit can materially reduce the amount a landlord may require. Use the calculator with your actual rent rather than a national average.
Credit history does not erase tenancy law
Newcomers sometimes encounter requests for extra money because they have little or no Canadian credit history. Deposit rules still matter. Before offering several months of rent or an extra “damage deposit,” check what the relevant tenancy authority allows and consider safer ways to strengthen an application, such as employment evidence, references or a guarantor where appropriate.
