What to Do If a Landlord Tries to Force a Rent Increase by Threatening to Withdraw Their Guarantor Signature in Ontario

In Ontario, a landlord cannot force a tenant to sign a new lease at a higher rent by threatening to ‘cancel’ a parent’s guarantor signature. Tenancies automatically convert to month-to-month, and a guarantor cannot unilaterally withdraw to facilitate an illegal rent increase.

Illegal Coercion Tactics in Ontario Student Housing

Renting as a student or young professional in university towns like Waterloo, Kingston, or Guelph often requires a co-signer or guarantor. Usually, a parent signs the tenancy agreement, promising to cover the rent if the student fails to pay. Unfortunately, some landlords use this requirement as a weapon when the initial one-year lease comes to an end. 🏠

A common illegal tactic involves the landlord telling the tenant that the guarantor’s liability “expires” at the end of the year. The landlord will threaten that unless the tenant signs a brand-new lease at a massively increased rent, they will “withdraw” the guarantor and evict the tenant. Under the Residential Tenancies Act (RTA), this is coercion and entirely illegal. If you are facing this stress, connecting with a paralegal from our directory can help you assert your rights and keep your rent affordable. ⚖

Step-by-Step Process: Protecting Your Rent and Tenancy

Do not panic and do not sign a new lease just because a landlord is pressuring you. Ontario law heavily favours the tenant’s right to remain in their home without being bullied into illegal price hikes. Here is what you should do. 📝

Step 1: Understand the Month-to-Month Rule

First, you must know that leases in Ontario do not truly “expire.” At the end of your one-year term, your tenancy automatically converts to a month-to-month arrangement under the exact same terms. You do not need to sign a new lease to stay, and you do not need to provide a new guarantor form. 📄

Step 2: Refuse the Illegal Rent Increase

A landlord can only raise your rent once every 12 months, and they must use an official Form N1 or N2, giving you 90 days’ notice. Furthermore, if your building is rent-controlled (occupied before November 2018), they can only raise it by the provincial guideline, which is set at 2.1% for the entire year of 2026. Politely reply in writing that you will be continuing month-to-month and will only accept a legal rent increase via the proper forms. 💵

Step 3: Ignore Threats About the Guarantor

The guarantor’s contract is legally binding. A landlord cannot randomly release a guarantor just to manufacture a reason to evict you. Similarly, your parent cannot just “withdraw” their signature to force a new contract. The original guarantee remains intact as the lease goes month-to-month. 🔒

Step 4: File a T2 Application for Harassment

If the landlord continues to email, call, or threaten you with eviction over the guarantor issue, they are committing harassment. You can file a Form T2 (Application about Tenant Rights) with the Landlord and Tenant Board. The LTB can order the landlord to stop the harassment and even pay you financial compensation for the stress caused. 👤

How Much Does It Cost to Defend Your Rights?

Standing up to a bully landlord is highly cost-effective, especially when compared to paying hundreds of dollars extra per month in illegal rent. Here are the standard costs for defending your tenancy in Ontario. 💰

Action / Legal ExpenseEstimated Cost in CAD
Refusing the new leaseFree. You simply keep paying your current lawful rent.
Filing a T2 Application (LTB)$48 CAD if filed online (or $53 CAD for paper filings).
Consulting a ParalegalAn initial advice session usually costs $150 to $300 CAD.

How Long Can You Stay Month-to-Month?

You can remain on a month-to-month tenancy indefinitely. The landlord cannot force you out simply because time has passed. If you have to file a T2 harassment application to get them to back down, be prepared to wait 6 to 10 months for a hearing date due to LTB delays, but your tenancy remains fully protected during that time. ⏳

Frequently Asked Questions (FAQ)

Can a guarantor actually cancel their liability?

Usually, no. Unless the specific guarantee contract explicitly stated it only applied for the first 12 months (which is rare for landlord-drafted forms), the guarantor remains liable as long as the tenancy continues on a month-to-month basis.

Can the landlord evict me if the guarantor dies or goes bankrupt?

No. Under the RTA, a change in your financial backing or your guarantor’s status is not a legal ground for eviction, provided you continue to pay your rent on time every month.

What if I already signed the illegal new lease out of fear?

If you were coerced into signing an illegal rent increase above the provincial guideline without a valid N1 form or a legal N10 agreement, you can file a T1 application to get the illegal overpayments refunded to you.

Does a new roommate require a new lease and guarantor?

No. If you just move a roommate in to help pay rent, they are an occupant, not a tenant. The landlord cannot force you to sign a new lease or demand a new guarantor for an occupant.
