You signed as a guarantor for a friend’s apartment in Toronto, and now they want you off the lease. In Ontario, a co-signer cannot simply walk away — you remain legally responsible for unpaid rent and damages until the landlord agrees in writing to release you, the fixed term ends, or the tenancy is legally terminated. That’s the reality under the Residential Tenancies Act. What follows are the actual pathways, costs, and traps that most people only discover after they’re stuck.

These figures come from Ontario’s landlord-tenant system, but similar patterns hold across Canada. The Landlord and Tenant Board (LTB) cannot release a guarantor — its jurisdiction covers only tenants and landlords. If the landlord refuses to let you go, your only court option is Ontario Small Claims Court for debts under $35,000. Here’s what you actually need to know.
Four Things to Know About Removing a Lease Cosigner
What I tend to notice is that most people don’t realise the guarantee can outlast the initial lease term. If the lease renews automatically month-to-month and the guarantee says “continues indefinitely,” you’re still on the hook. That’s worth weighing against any quick fix.
What It Actually Costs to Get Out
The purchase price of freedom isn’t zero. Even when the tenant is paying on time, the landlord may demand payment of existing arrears — typically between $1,000 and $3,000 CAD — as a condition of release. Legal fees for reviewing the guarantee and drafting a release letter run $200 to $500. If the tenant assigns the lease to someone else, the landlord can charge administrative expenses, usually $50 to $250.

| Cost Type | Typical Range (CAD) | Who Pays |
|---|---|---|
| Arrears payment | $1,000 – $3,000 | Guarantor or tenant |
| Legal review & release letter | $200 – $500 | Guarantor |
| Assignment fee | $50 – $250 | Tenant or new tenant |
| New credit check / screening | $30 – $100 | Tenant |
These numbers assume Ontario. In British Columbia, security deposits are capped at one month’s rent, which limits the landlord’s ability to demand extra deposit as a substitute for a guarantor. In Quebec, most deposits are prohibited entirely. The cost picture shifts by province, but the principle holds: removal almost always involves some outlay.
Common Mistakes That Keep You Trapped
Thinking you can just send a letter and walk away
A registered letter stating you’re terminating your guarantee only works if the fixed term is ending and the guarantee agreement did not say it continues indefinitely. Even then, you need to prove the landlord received it. Many guarantees contain clauses that keep you liable through month-to-month renewals. Sending a letter without checking the original wording is a gamble.
Moving out and assuming that ends your liability
If the tenant stays, moving out does nothing to your guarantee. You are still on the hook for rent and damages until the lease ends or the landlord releases you. The only exception is if the tenant legally assigns the lease to a new person under the Residential Tenancies Act — then the old tenant is released, and your obligations are severed. But a sublet, where the original tenant remains liable, does not release you.
Ignoring the month-to-month trap
In Ontario, when a fixed-term lease ends, it automatically converts to month-to-month unless the tenant signs a new fixed-term lease. Most guarantee agreements are drafted to keep you liable through that month-to-month period. If you assumed your obligation ended after 12 months, you may be in for a surprise. The only way to stop it is to send a formal registered letter before the fixed term expires, stating the guarantee termination date — and only if the agreement allows it.
Relying on verbal promises from the landlord
A landlord who says “don’t worry, I’ll release you” without signing anything leaves you fully exposed. Under joint and several liability, you remain 100% responsible until a signed lease amendment or release form is executed. Oral agreements are not enforceable in this context. Get it in writing, signed by all parties, and keep a copy.
Step-by-Step: How to Actually Remove a Cosigner
Review the original guarantee agreement
Find the lease and the specific guarantee document you signed. Look for clauses that say when the guarantee ends — does it expire after the fixed term, or does it continue through renewals? Also check whether the lease allows mid-term amendments. This determines your legal path. If the lease is silent, you must rely on the landlord’s discretion.
Prove the tenant can stand alone
Landlords will only release a guarantor if the tenant demonstrates financial reliability. Have the tenant gather pay stubs (2–3 months), bank statements, a current credit report (score 620–700+), and a record of on-time rent payments for at least 12 months. Most landlords want to see a debt-to-income ratio at or below 43% and rent no more than 30–35% of gross monthly income. Present this as a complete package.
Negotiate with the landlord
Approach the landlord formally in writing. Propose either a lease amendment removing your name, or a lease assignment to a new tenant. If the landlord hesitates, offer alternatives: a replacement guarantor with stronger finances, an increased security deposit (1–2 months’ extra rent), or prepaying several months of rent. A replacement cosigner is often the smoothest route when the original guarantor needs off quickly.
Get the release in writing
Once the landlord agrees, everything must be documented. A signed cosigner release form, lease addendum, or lease amendment is the only document that legally terminates your obligations. It should state your name, the effective date of release, and confirmation that you are released from all future liability. All parties — landlord, tenant, and you — must sign. Keep copies for your records.
If the landlord refuses: assign or wait
If the landlord won’t release you, your next best option is to have the tenant assign the lease to a new renter. Under the RTA, a legal assignment severs your obligations. The landlord can charge a reasonable assignment fee ($50–$250). If the tenant is unwilling to move, you may have to wait until the fixed term expires and send a registered letter terminating your guarantee — but only if the agreement allows it. That wait can be 6 to 12 months.
What about future lease reforms?
Ontario’s renting information page notes ongoing updates to LTB processes, but no specific reform targets guarantor release. In Quebec, the Duranceau reforms (2026) affect relocation compensation and notice periods, but not guarantor removal. For now, the rules remain landlord-dependent. If you’re considering cosigning a future lease, insist on a limited guarantee with a dollar cap and an exact end date tied to performance (e.g., 12 consecutive on-time payments).

Your Liability Ends Only When the Landlord Signs
The single most important takeaway is this: no document, no release. A verbal agreement, a handshake, or a friendly email does not end your legal obligation. Until a signed lease amendment or release form exists, you remain fully liable under joint and several liability — meaning the landlord can come after you for the entire rent if the tenant stops paying. If you’re currently a cosigner and want off, start by reading the guarantee agreement, then have the tenant prove their financial stability, and negotiate in writing. If the situation has become unworkable, consider consulting a Canadian landlord-tenant lawyer through JustAnswer to review your options.
