Can a Landlord Increase Rent if You Move a Significant Other into Your Unit in Ontario?

13 Jun 2026 4 min read No comments Landlord & Tenant Rights Ontario
💡

In Ontario, it is completely illegal for a landlord to raise your rent or charge an “extra occupant fee” simply because your spouse, partner, or roommate moves in. Tenants have a legal right to have guests and roommates under the RTA, and violating this can lead to massive LTB fines for the landlord.

Finding affordable housing in Ontario cities like London, Hamilton, and Ottawa is incredibly challenging. Consequently, moving in with a significant other is a major milestone that also helps split the rising cost of living.

However, many tenants are shocked when their landlord suddenly demands an extra $200 CAD a month for the new occupant. 🚨 Unless you share a kitchen or bathroom directly with the landlord, these “extra guest fees” are strictly prohibited under the Residential Tenancies Act (RTA).

Step-by-Step Process for Handling Illegal Occupant Fees

Landlords often rely on the fact that tenants do not know their legal rights. They might point to a custom clause buried in your lease that says “no overnight guests” or “single occupancy only.”

Under Ontario law, these clauses are void and unenforceable. 📝 If your landlord attempts to bully you into paying more for your partner, here is the exact process to defend your tenancy.

Step 1: Review Your Standard Form of Lease

Since April 2018, almost all residential tenancies in Ontario must use the government’s standard lease form. Review this document carefully.

You will notice that the standard lease explicitly states that landlords cannot ban guests or charge extra fees for them. 📍 Any custom appendix the landlord stapled to the back attempting to override this rule is legally meaningless.

Step 2: Notify the Landlord in Writing

You are not legally required to ask your landlord for permission to move your partner in. However, it is polite and practical (for emergency and fire safety reasons) to inform them in writing that another person is residing in the unit.

If the landlord replies by demanding increased rent, firmly state in writing that “extra occupant fees are prohibited under Section 22 of the Residential Tenancies Act.” 💬 Keep all of these emails as evidence.

Step 3: Refuse to Pay the Illegal Increase

Do not be intimidated into paying a higher amount. Continue to pay your exact, lawful rent on the first of the month.

If you accidentally pay the increased amount for an entire year, it could legally become your new lawful rent. 🚫 You must stand your ground and pay only what is stated on your original lease or a lawful N1/N2 notice.

Step 4: Ignore Empty Threats of Eviction

A landlord might threaten to evict you by serving an N5 notice for “interfering with the landlord’s rights” or claiming the unit is overcrowded.

Unless you are moving ten people into a bachelor apartment and violating municipal health and safety bylaws, the Landlord and Tenant Board (LTB) will quickly dismiss their eviction attempt. ✅ Two people sharing a one-bedroom apartment is perfectly legal.

Step 5: File a T2 Application for Harassment

If the landlord relentlessly harasses you, blocks your partner from entering the building, or constantly texts you demanding money, you must take legal action.

File a T2 Application with the LTB. You can request that an adjudicator order the landlord to stop the harassment and award you financial compensation (a rent abatement) for the stress they caused. 💼

How Much Does it Cost in Ontario?

Defending your right to have your partner live with you is relatively inexpensive, especially compared to the cost of paying an illegal fee every month.

  • LTB Filing Fee: Filing a T2 application online costs about $53 CAD for a tenant.
  • Paralegal Advice: Consulting a law firm or paralegal for a warning letter usually costs $200 to $500 CAD.
  • Illegal Fee Recovery: If you mistakenly paid the illegal occupant fee, you can file a T1 application to force the landlord to refund every dollar they unlawfully collected.

How Long Does the Process Take?

If you refuse to pay the illegal fee, the issue is often resolved instantly, as the landlord realizes you know the law and backs down.

However, if they decide to relentlessly harass you and you file a T2 application, securing a hearing date at the LTB currently takes between 6 to 8 months. ⌛ During this time, your partner has every right to remain in the apartment.

Lawful Rent Increase vs. Illegal Fee

Understanding the difference ensures you never overpay for your apartment.

Frequently Asked Questions (FAQ)

Does my partner automatically become a tenant?

No. Your partner is considered a “roommate” or “occupant” under the law, not a tenant. They do not have a direct legal relationship with the landlord, and you remain 100% responsible for paying the rent and any damages they cause.

What if my lease explicitly says “No overnight guests”?

That clause is completely void under the Residential Tenancies Act. A landlord cannot legally enforce a ban on guests or roommates, and you cannot be evicted for ignoring that specific, illegal clause.

Can the landlord increase rent if utilities are included?

Even if you have an all-inclusive lease where the landlord pays for hydro and water, they still cannot increase your base rent just because a second person is using more water. They must absorb the extra utility cost as part of doing business in Ontario.

Can I add my partner’s name to the lease?

You can request to add your partner to the lease as a co-tenant, but the landlord must agree. If they agree, be careful: landlords sometimes use this request as an excuse to draft a brand new lease at a much higher, current market rent.
