Renting an apartment in Canada often means facing a rental market where vacancy rates in major cities like Toronto and Vancouver hover around 1% to 1.5%. With average one-bedroom apartments in Toronto exceeding $2,800 monthly and Vancouver pushing past $3,000, landlords are increasingly selective. If your income doesn’t meet the common threshold of three times the monthly rent, or if you have limited credit history, a landlord will likely ask for a guarantor or co-signer before approving your application.

Landlords aren’t being unreasonable — they’re covering their risk in a market where rent consumes a large chunk of income. But the difference between a co-signer and a guarantor matters more than most renters realise. The wrong arrangement can leave someone on the hook for damages they never caused. Here’s what you actually need to know.
What a Guarantor Actually Does and How It Differs from a Co-Signer
Most people use the terms co-signer and guarantor interchangeably, but the legal difference is significant. A guarantor steps in only after you fail to pay — the landlord must first pursue you before going after them. A co-signer is equally responsible from the start. Landlords can demand payment from either party at any time.
What I tend to notice is that tenants often rush to find anyone willing to sign, without checking whether the person understands the difference. A parent who agrees to be a co-signer thinking they’re just a backup could be in for a surprise.
When Landlords Can and Cannot Ask for a Guarantor
Landlords in Canada can request a guarantor when they see genuine financial risk. That includes applicants with no rental history, poor credit, no Canadian credit file, inconsistent self-employment income, or bad references. In a market where vacancy rates sit below 2%, landlords have the leverage to make these requests stick.
But there are limits. Ontario’s Human Rights Code prohibits landlords from demanding a guarantor based on protected grounds like race, age, or family status. The Ontario Human Rights Commission specifically rejects blanket practices aimed at protected groups. A landlord cannot ask only international students for a guarantor while waiving it for Canadian-born applicants with similar finances.
The practical test is consistency. If a landlord requires a guarantor from every applicant who doesn’t meet the 3x income rule, that’s likely fine. If they only ask people from certain backgrounds, that’s discrimination.
If you’re unsure whether a landlord’s request is reasonable, a landlord-tenant lawyer can review the situation. The cost of a consultation is usually far less than the risk of signing a bad agreement.
Common Mistakes Renters and Guarantors Make
Assuming the label on the document doesn’t matter
Many people sign a lease addendum that calls them a “guarantor” but the wording makes them a co-signer. If the document says they are “jointly and severally liable” from day one, they’re a co-signer regardless of the title. Read the actual liability clause, not the heading.
Not checking whether the guarantor can be pursued for damages
Guarantors in Ontario can be held liable for unpaid rent and property damages, not just missed payments. If the tenant causes $5,000 in damage and disappears, the landlord can go after the guarantor for the full amount. The guarantor’s credit score takes the same hit as the tenant’s.
Thinking the guarantor’s responsibility ends when the lease ends
In Ontario, if the lease renews or goes month-to-month, the guarantor’s obligation often continues unless the original agreement explicitly states otherwise. A guarantor who signed for a one-year lease might still be on the hook three years later.
Ignoring the human rights angle
If a landlord asks for a guarantor only from students, new immigrants, or specific ethnic groups, that’s a human rights violation. The request must be based on financial criteria applied uniformly. Tenants who suspect discrimination can file a complaint with the Ontario Human Rights Tribunal.
How to Apply for a Rental with a Guarantor
Step 1: Confirm the guarantor understands the obligation
Before anything else, sit down with the potential guarantor and explain what they’re signing. They need to know they could be liable for unpaid rent, damages, and legal costs. If they’re not comfortable, look for another option.
Step 2: Gather the guarantor’s financial documents
Landlords will want proof of income, a credit check, and sometimes bank statements. The guarantor typically needs to show they earn enough to cover both their own expenses and your rent. A credit score above 700 is generally expected.
Step 3: Review the standard lease and guarantor agreement
Ontario requires the Residential Tenancy Agreement (Standard Form of Lease) for most private rentals. The guarantor’s responsibilities should be in a separate guarantor form or an addendum to the lease. Make sure it specifies what the guarantor is responsible for, when responsibility starts and ends, and whether it continues after the initial lease term.
Step 4: Sign and keep copies
Both the tenant and guarantor should sign the lease and any guarantor documents. Keep signed copies for both parties. Digital signatures are generally accepted, but check with the landlord first.

What happens if the guarantor lives outside Canada
Some landlords accept foreign guarantors, but it’s less common. The landlord needs to be able to enforce the agreement in another jurisdiction, which adds cost and complexity. A Canadian-based guarantor is almost always preferred.

What the Guarantor Requirement Means for Your Rental Search
The guarantor requirement isn’t going away as long as Canada’s rental market stays tight. With rent consuming over 32% of average income and vacancy rates below 2% in major cities, landlords will keep asking for backup. The smartest move is to find a guarantor who understands the full scope of liability and to get the agreement in writing with clear terms.
