Under the Residential Tenancies Act (RTA) in Ontario, if at least one original leaseholder remains in the unit, bringing in a new roommate is not a sublet or lease assignment. Therefore, a landlord is strictly prohibited from charging “administrative fees,” demanding a higher security deposit, or increasing the rent just because you changed roommates.
Renting a multi-bedroom apartment in a major city like Toronto, Mississauga, or London often means a rotating cast of roommates. As people graduate, change jobs, or move in with partners, the secondary occupants of a rental unit frequently cycle out. When this happens, some property management companies attempt to capitalize on the turnover by demanding a $200 “admin fee” or attempting to raise the rent, claiming the lease has changed. 🚨
Understanding Landlord & Tenant Rights in Ontario is your best defence against these unlawful practices. The law is exceptionally clear: a tenant has the right to have guests, occupants, and roommates without the landlord’s permission, provided the unit does not violate municipal overcrowding bylaws. 📝 As of May 2026, paying illegal charges out of fear is unnecessary, and knowing how to assert your rights can save you hundreds of dollars.
Step-by-Step Process for Handling Illegal Admin Fees
If your landlord issues an invoice or demands payment simply because your roommate moved out and a new one moved in, you must handle the situation methodically. Whether you rent in Brampton or Ottawa, the rules enforced by the Landlord and Tenant Board (LTB) remain identical. Here is how most applicants protect themselves from illegal charges. 📋
Step 1: Understand the Definition of a Roommate
First, verify that your situation actually involves a roommate change and not a full lease assignment. If you are the primary leaseholder and you are staying in the apartment, bringing someone else in to share the rent makes them a roommate (an occupant). 👀 Because the original tenancy has not ended, the landlord has no legal right to intervene, screen the roommate, or charge a fee.
Step 2: Communicate the Law in Writing
If the landlord demands an admin fee, respond politely but firmly in writing. Send an email pointing out that under the Ontario Residential Tenancies Act, specifically regarding the right to reasonable enjoyment, tenants are permitted to have roommates. 💬 Inform them that the LTB consistently rules that charging fees for roommate changes is an illegal penalty.
Step 3: Refuse to Pay the Illegal Fee
You have the legal right to simply refuse to pay an illegal charge. Continue paying your exact legal rent amount on the first of the month. 💰 Do not deduct anything, but do not add the admin fee. If the landlord threatens to evict you for “unpaid fees,” you can rest easy knowing that the LTB will not process an eviction for an illegal administrative charge.
Step 4: Filing a T1 or T2 Application at the LTB
If you already paid the fee out of fear, or if the landlord is harassing you over your refusal, you must escalate the matter. You can file a T1 Application for a rebate of money the landlord collected illegally. 📄 If the landlord is continuously calling you or threatening eviction, your paralegal or law firm can also file a T2 Application for substantial interference with your reasonable enjoyment of the unit.
How Much Does it Cost to Fight Illegal Fees?
Fighting back against a landlord’s illegal fees is relatively inexpensive, especially if you handle the LTB applications yourself. The RTA is designed to be accessible to standard renters without requiring a massive legal budget. Here is a breakdown of the costs in CAD: 💸
- LTB Filing Fees: Filing a T1 (Rebate) or T2 (Tenant Rights) application online via the Tribunals Ontario Portal costs roughly $48 to $53 CAD.
- Legal Consultation: Booking a one-hour consultation with a local housing lawyer or licensed paralegal to review your lease usually costs $150 to $300 CAD.
- Full Representation: If you hire a paralegal to draft the forms and argue your case at the virtual hearing, expect to pay between $800 and $1,500 CAD.
- Cost Recovery: If you win, the adjudicator will almost always order the landlord to reimburse you for the $53 LTB filing fee.
| Legal Step / Action | Estimated Cost (CAD) | Recoverable if you Win? |
|---|---|---|
| Refusing to Pay the Fee | $0 | N/A |
| Filing T1/T2 Online | $53 | Yes |
| Paralegal Representation | $800 – $1,500 | Sometimes (Partial costs) |
How Long Does the LTB Process Take?
Patience is absolutely required when dealing with the Landlord and Tenant Board. If you file a T1 application to get your illegal admin fee refunded, you will enter the standard queue. 🕑 As of mid-2026, tenant-filed applications (like T1s and T2s) are routinely taking anywhere from 6 to 10 months to reach a virtual hearing date. However, since you are safely inside your unit, time is generally on your side while you wait for the adjudicator’s order.
Frequently Asked Questions (FAQ)
Can the landlord force my new roommate to sign the lease?
No. As long as you (the original tenant) are still living there, the landlord cannot force the new roommate to sign an addendum or a brand new lease. If you do voluntarily agree to sign a new lease, the landlord is legally allowed to raise the rent to current market rates, so it is highly unadvised.
What is the difference between a roommate and a subtenant?
A roommate shares the apartment with the primary tenant who is currently living there. A subtenant is someone who temporarily takes over the entire apartment because the primary tenant moved out for a specific period (e.g., a four-month summer break). Sublets require landlord consent; roommates do not.
Can the landlord restrict how many roommates I have?
The landlord cannot randomly dictate the number of guests or roommates. However, you are strictly bound by the municipal property standards and overcrowding bylaws (e.g., in Toronto or Mississauga), which dictate the maximum number of occupants based on the square footage of the bedrooms.
Am I responsible if my new roommate damages the property?
Yes, completely. Because the roommate is not on the official lease, the landlord has no legal relationship with them. If your roommate punches a hole in the wall or causes a flood, the landlord will take you to the LTB for the damages, and you will have to sue the roommate in Small Claims Court later.
