Co-Signer vs Guarantor: Manitoba Rental Rules

Leases & Agreements Manitoba 4 min read · published June 24, 2026 Flag of Manitoba

Deciding whether you need a co-signer or a guarantor can affect your legal and financial responsibilities when renting in Manitoba. Tenants often face this choice when they have limited credit or income, or when a landlord requests extra security. This article explains the difference between a co-signer (joint tenant) and a guarantor, what each person signs, and how Manitoba tenancy rules treat their obligations. You will learn when a landlord can require one, what forms and proof landlords may ask for, and practical steps to protect your rights if you are a renter, co-signer, or guarantor. Clear examples and links to official Manitoba resources are included so you can act with confidence.

What is a co-signer and what is a guarantor?

A co-signer signs the lease and is usually a joint tenant, which means they share the same legal obligations as the named tenant. A guarantor signs a separate guaranty agreement promising to pay or perform only if the tenant fails to do so. In Manitoba, these arrangements are governed by provincial tenancy rules and can affect who is responsible for unpaid rent, damages, or other lease obligations.[2]

Read any guarantee or co-signer clause carefully before signing.

When can a landlord ask for a co-signer or guarantor in Manitoba?

Landlords commonly request a co-signer or guarantor when an applicant has limited credit history, irregular income, or is a student. The landlord should make the requirement clear before signing a lease and must treat all applicants fairly under Manitoba tenancy rules. Landlords can also request proof such as pay stubs, references, or a completed guaranty form. For details on required forms and where to file, see official Residential Tenancies Branch resources.[1]

Practical examples include:

  • A student with no credit history may be asked to provide a guarantor to cover potential unpaid rent or damages.
  • An applicant with part-time income might be asked for a co-signer whose income increases the landlord's confidence.
  • A guarantor may be required to complete and sign a standard guaranty form supplied by the landlord.
Ask the landlord whether the guaranty is limited in time or dollar amount before agreeing.

Legal responsibilities: who is on the hook?

Co-signers who are listed on the lease are generally jointly and severally liable with the tenant for rent and other obligations. That means a landlord can pursue any co-signer directly for unpaid rent or damages. A guarantor’s obligation is typically secondary: the guarantor pays only if the tenant defaults and the landlord has followed the required steps to pursue the tenant first. Always read the exact language of the lease and any separate guaranty to know the scope of liability.[2]

Signing as a co-signer or guarantor can have long-term financial consequences if the tenant defaults.

Forms, filing and official steps in Manitoba

If a dispute arises (for unpaid rent, damage claims, or eviction), tenants, co-signers, and guarantors may need to deal with the Residential Tenancies Branch. Typical official steps include submitting an application for dispute resolution and supplying evidence such as the lease, guaranty, receipts, and photos. The Branch publishes official forms and instructions that explain filing requirements and timelines.[3]

How co-signers and guarantors can protect themselves

  1. Get every promise in writing: keep copies of the lease, any guaranty agreement, and receipts for rent or deposits.
  2. Limit the guaranty when possible: ask for a written clause that caps the dollar amount or duration of the guaranty.
  3. Document move-in condition with photos and a signed checklist to reduce disputes about damages.
  4. Respond to any notices or letters promptly and keep records of all communications with the landlord and the Residential Tenancies Branch.
Documentation and prompt responses make dispute resolution smoother and fairer.

Examples: short scenarios

  • If rent is unpaid and the tenant leaves, a co-signer listed on the lease may be held responsible immediately.
  • A guarantor who signed a separate agreement may only be required to pay after the landlord obtains an order through the Residential Tenancies Branch or court.

FAQ

Can a Manitoba landlord require a guarantor?
Yes. A landlord can require a guarantor if the landlord sets this condition before signing the lease, but the requirement must be applied consistently and in compliance with human rights and tenancy laws.
Is a co-signer equally responsible for rent?
Generally yes: a co-signer on the lease is usually jointly and severally liable for rent and obligations just like the named tenant.
Can a guarantor be removed later?
Only if the landlord agrees in writing or if a new agreement is signed releasing the guarantor; otherwise the guarantor remains bound until the guaranty terms end.

How-To

  1. Review your lease and any guaranty carefully and note dates, amounts, and signatures.
  2. Ask the landlord to add limits or a sunset clause to a guaranty if you are acting as guarantor.
  3. If a dispute occurs, gather evidence (receipts, photos, messages) and file the appropriate Residential Tenancies Branch application using official forms.
  4. Seek free or low-cost legal advice if you are unsure about signing or after receiving a notice; act within the timelines shown on any official notice.
