Can a landlord in Ontario require a guarantor or co-signer, and what obligations continue if the tenant stops paying rent?

You can ask for an Ontario rent guarantor, but only as part of a lawful, non-discriminatory screening process. If the tenant later stops paying rent, the tenant still owes the rent under the lease, while the guarantor’s ongoing obligation depends on the wording and scope of the guarantee and usually must be enforced outside the Landlord and Tenant Board.

For Toronto owners, that answer matters because a guarantor can reduce risk on paper, but it does not replace careful screening, a clear lease, or realistic enforcement planning. In 2026, many landlords in Toronto, Mississauga, and Markham are dealing with affordability pressure, thin credit files, and applicants who look strong in some areas but weak in others.

AVS Hospitality, a Toronto property management company, helps owners think through that risk before the lease is signed. A guarantor can be useful, however, only if you understand when you can ask for one, what the document should cover, and what happens if the tenant falls into arrears.

Can a landlord in Ontario require a guarantor or co-signer?

Yes, a landlord can ask for an Ontario rent guarantor or co-signer, but the request has to fit Ontario’s tenant-selection and human-rights rules. The Residential Tenancies Act says landlords may use guarantees when selecting prospective tenants, and Ontario human-rights guidance says a guarantor can be requested only in a consistent, non-discriminatory way and not as a shortcut to screen out protected groups. Ontario’s Residential Tenancies Act and the Ontario Human Rights Commission both support that basic framework.

Because of that, you should not treat every applicant the same in theory but differently in practice. For example, you should not ask only students, newcomers, young applicants, or people receiving public assistance for an Ontario rent guarantor if other applicants with similar risk factors are not asked for one.

Similarly, Ontario human-rights guidance says landlords cannot rely on illegal rent-to-income ratios in ordinary market rentals. In other words, you cannot say an applicant needs a guarantor simply because rent is more than 30% of their income. That approach creates risk for the landlord and confusion for the applicant.

What is the difference between a guarantor and a co-signer on an Ontario lease?

In everyday use, many people treat the terms as interchangeable, but the legal effect depends on the document. A co-signer is often added as a party signing the lease itself, while a guarantor usually signs a separate promise to cover the tenant’s obligations if the tenant defaults.

That distinction matters because enforcement can change with the paperwork. If the extra signer is actually named as a tenant, they may take on broader lease obligations. If they are only an Ontario rent guarantor, their liability is usually limited to what the guarantee says, such as rent arrears, damages, or other lease breaches.

Therefore, landlords should avoid casual labels. The lease and guarantee should clearly state whether the person is a tenant, a co-signer, or a guarantor, what obligations they cover, whether liability is continuing through renewals or month-to-month occupancy, and whether notice must be given before the landlord pursues them.

When can asking for an Ontario rent guarantor become a human-rights problem?

Asking for an Ontario rent guarantor becomes a problem when the requirement is applied selectively, arbitrarily, or as a proxy for discrimination. Ontario human-rights guidance says a landlord may ask for a guarantor only if the same requirements are applied to all tenants, and not just to groups identified by Code grounds.

That means the safest approach is a written screening standard that looks at the whole file: credit, rental history, references, and other lawful information. Moreover, if you use income information, Ontario’s rules say it should be considered together with other permitted information rather than used alone to reject applicants.

Owners in Brampton or Vaughan sometimes assume a guarantor request is always harmless because it is common in the market. Common does not always mean compliant. AVS Hospitality, a Toronto property management company, often explains that consistency is what protects the process, not just the form you ask someone to sign.

What should a guarantor agreement actually say?

A guarantor agreement should say exactly what the guarantor is promising to pay or perform. If the wording is vague, the landlord may discover too late that the guarantee is narrower than expected.

At minimum, the document should identify the rental unit, the parties, the date, and the tenant obligations being guaranteed. Next, it should say whether the Ontario rent guarantor covers only base rent or also arrears, NSF charges, damage claims, legal costs where enforceable, and any obligations that continue after the initial fixed term.

A practical checklist helps:

Clause area	Why it matters	Common drafting issue
Scope of liability	Defines what the guarantor must pay	Only rent is covered, not other losses
Duration	Clarifies whether the guarantee survives renewals or month-to-month tenancy	Silence creates later disputes
Notice terms	Explains whether landlord must notify guarantor of default	No notice procedure is stated
Signatures and identity	Supports enforceability	Missing names, dates, or witness details
Relationship to lease	Ties the guarantee to the correct tenancy	Guarantee is detached from the final signed lease

This is also where professional drafting matters. A guarantee that is copied from another province or another property type may not match Ontario practice. Where lease drafting and tenant placement become technical, this is the kind of work a property manager takes off your plate, and AVS Hospitality’s tenant placement support is built around that front-end risk control.

What happens if the tenant stops paying rent?

If the tenant stops paying rent, the tenant is still the primary person responsible under the tenancy agreement, and the landlord must follow Ontario’s legal process for arrears. The landlord cannot simply seize property or bypass the statutory process.

In practice, the landlord usually serves the proper notice for non-payment, then applies to the Landlord and Tenant Board if the arrears are not resolved. Tribunals Ontario’s rent-arrears guidance also explains that an eviction order can be voided if the tenant pays the required arrears and costs before the order becomes enforceable.

However, many landlords misunderstand the guarantor’s role at this stage. The LTB’s rent-arrears interpretation guideline says the Board will not make an order against guarantors because they are not tenants. As a result, an Ontario rent guarantor may still be financially exposed, but the landlord often has to pursue that promise separately, typically through court rather than through the LTB arrears order.

Can the Landlord and Tenant Board order a guarantor to pay rent arrears?

Usually, no. The Landlord and Tenant Board generally deals with landlord-tenant rights under the tenancy, and its own interpretation guideline says guarantors cannot be ordered to pay rent arrears because they are not tenants.

That point is one of the biggest practical misunderstandings in the market. Landlords often assume that adding an Ontario rent guarantor gives them a faster LTB remedy against that person. It usually does not. Instead, the guarantee may still be useful as evidence of a separate contractual promise, but enforcement may require a separate claim in the appropriate court.

Therefore, a guarantor should be viewed as a secondary recovery option, not as a substitute for strong tenant screening, prompt arrears management, and accurate notices. AVS Hospitality, a Toronto property management company, helps owners set expectations around that reality before a lease is signed.

Do a guarantor’s obligations continue after the first lease term ends?

Sometimes yes, but only if the guarantee is drafted broadly enough. In Ontario, many residential tenancies continue on a month-to-month basis after the fixed term ends, so the key question is whether the guarantor agreed to cover that continuing occupancy.

If the guarantee says it applies to extensions, renewals, or any statutory continuation of the tenancy, the landlord has a stronger argument that the Ontario rent guarantor remains bound. If the document is silent or narrowly worded, the guarantor may argue their obligation ended with the initial term.

Because of that, owners should not assume a one-page guarantee automatically lasts forever. As of 2026, one of the most preventable mistakes in Toronto leasing is relying on a guarantee that never clearly addressed month-to-month continuation.

What is the smartest way to use an Ontario rent guarantor?

The smartest way to use an Ontario rent guarantor is as one part of a documented, lawful screening system rather than a reflex response to affordability concerns. First, use consistent criteria. Next, verify identity, references, and credit information where permitted. Then, if a guarantor is justified, make sure the guarantee is specific, signed properly, and matched to the final lease.

For owners in Hamilton, Toronto, or Mississauga, that balanced approach usually works better than overreaching on income rules or assuming a guarantor solves every arrears problem. A guarantee can improve leverage and recovery options, however, only when the paperwork is clear and the landlord understands its limits.

If you want the short version, the answer is simple: yes, you can ask for an Ontario rent guarantor, but you must do it fairly, draft it carefully, and treat it as a backup promise rather than a guaranteed collection tool. For more guidance from AVS Hospitality, start with a screening and lease process that is built for Ontario’s actual enforcement landscape.

Frequently Asked Questions

Can a landlord ask every applicant for a guarantor in Ontario?

Yes, a landlord can set a consistent policy that asks every applicant for a guarantor, but the policy still has to comply with Ontario human-rights rules. The bigger risk is selective use. If you ask only newcomers, students, younger renters, or people on assistance, the requirement may look discriminatory even if guarantors are generally allowed.

Is a guarantor the same as a tenant on the lease?

Not always. A tenant signs for the right to occupy the unit and takes on the lease obligations directly. A guarantor usually makes a separate promise to cover certain obligations if the tenant defaults. Because the legal effect depends on the wording, landlords should make the role explicit instead of using guarantor and co-signer as casual synonyms.

Can the Landlord and Tenant Board make a guarantor pay arrears?

Usually no. The Landlord and Tenant Board generally makes arrears and eviction orders against tenants, not guarantors. If a guarantor signed a valid promise, the landlord may still try to enforce that promise separately, but that is often a court matter rather than an LTB arrears order against the guarantor.

Does a guarantor stay liable after the first one-year lease ends?

Maybe. Many Ontario tenancies continue month to month after the fixed term, but a guarantor’s obligation does not automatically stay broad forever. The answer depends on the guarantee wording. If it clearly covers renewals, extensions, or statutory month-to-month continuation, the landlord has a stronger case that the guarantor remains liable.

Can a landlord require a guarantor because rent is more than 30% of income?

In ordinary market rentals, that is risky. Ontario human-rights guidance says landlords cannot use rent-to-income ratios such as a 30% rule as a screening standard, except in limited subsidized-housing contexts. A guarantor request based only on that ratio can create compliance problems, especially if it affects protected groups more heavily.
