What Are You Actually Signing in an Ontario "Agreement to Lease"? And How It Relates to the Standard Lease
OREA’s offer to lease is legally binding the moment it’s accepted — but it is not the government Standard Lease you’ll ultimately sign. Don’t confuse the two documents.
What is an Ontario "Agreement to Lease," and is it the same as the Standard Lease?
No, they’re not the same. The “Agreement to Lease” is OREA’s standard form, used in agent-assisted deals to let a tenant make an offer and a landlord accept it — setting rent, start date, term, and deposit. Once accepted, it is legally binding. But per Ontario rules, most private residential rentals also require the government’s Residential Tenancy Agreement (the Standard Lease), which the landlord must give the tenant within 21 days of the tenancy starting. In short: the Agreement to Lease is the binding deal at the moment of acceptance; the Standard Lease is the formal contract that puts the tenancy under the Residential Tenancies Act.

Come rental season, the most common confusion I see is this: a tenant signs the agent’s “Agreement to Lease,” assumes it’s done, and then the landlord produces a government “Standard Lease” to sign too. The tenant is baffled — “Didn’t I already sign? What if they conflict?” In fact the two do different jobs and don’t conflict. Here’s how they relate, the clauses to nail down when you sign an Agreement to Lease, and exactly how much deposit a landlord can collect — useful for tenants and landlords alike.

Two documents, two jobs
The Agreement to Lease is typically OREA’s standard form, used with an agent’s help. Its job is to close the deal: the tenant fills in the rent they’ll pay, the start date and term they want, and submits it with a deposit; once the landlord signs to accept, the two sides have a legally binding agreement. The Standard Lease is the formal contract Ontario requires for most residential rentals — it places the tenancy squarely under the protection of the Residential Tenancies Act (RTA). The first means “we’ve agreed”; the second means “it’s formalized under the law.”
Step 1: Nail down the core terms in the Agreement to Lease
⚠️Collecting a damage/security/pet deposit is not legal in Ontario. A landlord may take only a rent deposit of up to one month’s rent, usable only for the last month. A tenant asked for a damage deposit can decline and assert their rights at the LTB.
Step 2: Deposit can only be first + last — no damage deposit
ℹ️Verbal promises don’t count. Parking, internet, appliances, pets — anything agreed must be written into the Agreement to Lease or an attached schedule and carried into the Standard Lease, or it’s very hard to prove later.
Step 3: Get the government Standard Lease within 21 days
What each side should watch most
Tenants: submitting an offer is a serious bid — it takes effect the moment it’s accepted, so don’t treat it casually; and make sure you get and check the Standard Lease against it. Landlords: a proper Agreement to Lease locks terms and reduces disputes, but respect the deposit red line (no damage deposit), provide the Standard Lease on time, and understand that any clause trying to bypass the RTA won’t be upheld. Both sides should have an agent or professional review the schedules before signing.
💡 The Agreement to Lease is binding the moment it’s accepted — but it isn’t the finish line. The government Standard Lease is the formal, RTA-protected contract, and the landlord must provide it within 21 days. Spell out the core terms at the offer stage, hold the deposit red line (last month only, no damage deposit), and reconcile the two documents line by line, and you’ll head off most rental disputes before anyone signs.
Frequently Asked Questions
Can I back out after signing an Agreement to Lease?
Once the landlord accepts, the offer is legally binding and you can’t simply walk away; breaching it can carry liability. So confirm rent, start date, deposit, and inclusions before submitting, and treat it as a real contract — not a placeholder.
What if the Agreement to Lease and the Standard Lease conflict?
The Standard Lease is the formal contract protected by the RTA, and its mandatory provisions prevail over any term that tries to weaken a tenant’s legal rights. The two should match — reconcile them line by line before signing; a landlord can’t use add-on clauses to bypass RTA rights.
How much deposit can a landlord collect?
Per Ontario rules, only a rent deposit — at most one month for a monthly tenancy — and it can be applied only to the last month’s rent. Damage, security, and pet deposits are not legal. A refundable key deposit is allowed if the amount is reasonable.
What if the landlord never provides the Standard Lease?
Per Ontario rules, the landlord must provide the government Standard Lease within 21 days of the tenancy starting. If they don’t, the tenant can request it in writing; if it’s still withheld after that, the tenant may, under specific conditions, lawfully withhold up to one month’s rent. Consult the LTB or a professional on the exact steps.
