In Ontario, under Section 36.1 of the Residential Tenancies Act (effective July 1, 2026), tenants have the right to install window or portable air conditioners. However, if electricity is included in your rent, the landlord can legally charge a seasonal surcharge to cover the actual or estimated electricity cost of the unit (unless your lease explicitly prohibits it).
When the humid summer heat rolls into cities like Windsor, London, and Toronto, a window air conditioner becomes less of a luxury and more of a survival tool. ❄ However, as hydro rates increase, many Ontario landlords attempt to offset these costs by suddenly demanding seasonal A/C fees, sometimes asking tenants to pay an extra $100 to $200 CAD per month. This often leads to fierce disputes and threats of eviction.
Under the Residential Tenancies Act (RTA), tenants have historically had strong protections against sudden, unagreed-upon charges. However, landmark RTA amendments under Bill 97 introduce Section 36.1 (effective July 1, 2026). Under these new rules, while tenants are explicitly permitted to install window or portable A/C units, landlords who pay for electricity can legally charge a seasonal rent increase to cover the actual or estimated utility costs of the A/C unit. This guide explains how these new rules work, how to handle illegal overcharges, and how to assert your rights at the Landlord and Tenant Board (LTB).
Step-by-Step Process for Handling A/C Disputes in Ontario
If your landlord suddenly posts a notice demanding an air conditioning fee, you do not have to blindly comply. 📝 Most tenants successfully navigate this issue by following a clear, legally grounded process.
Step 1: Review the Ontario Standard Lease
The very first thing you must do is read your lease. Look at Section 6: Services and Utilities of the Ontario Standard Lease. If electricity is included in your rent, note that starting July 1, 2026, Section 36.1 of the RTA allows your landlord to charge a seasonal surcharge to cover the actual or reasonably estimated cost of electricity for a tenant-installed A/C unit, unless your lease explicitly states otherwise. If you pay your own hydro separately, the landlord cannot charge you any additional fee.
Step 2: Provide Written Notice to Your Landlord
Under the new rules, you must notify your landlord in writing before installing or using your A/C unit. 📧 If the landlord pays for electricity, you must provide details about the unit’s energy efficiency (such as the model, BTU, or energy-saver rating) and your expected daily usage so they can calculate a reasonable seasonal fee. If the landlord attempts to charge an arbitrary or extortionate amount, you can refuse the excess charge and request a proper calculation based on actual or reasonably estimated electricity costs.
Step 3: Ensure the Installation is Safe
While landlords often cannot charge for the electricity, they absolutely can demand that the A/C unit is safely installed. A falling window unit is a massive liability. To avoid receiving an N5 eviction notice for “property damage or safety hazards,” ensure your unit is securely bracketed, does not damage the window frame, and drips condensation away from the building’s brickwork.
Step 4: File a T2 or T1 Application at the LTB
If the landlord retaliates by physically removing a safely installed unit, shutting off your power, or charging a fee that exceeds actual electricity costs, you must fight back. ⚙️ You can file a T2 Application (Reasonable Enjoyment/Harassment) or a T1 Application (Rebate for Illegal Charges) with the Landlord and Tenant Board. The LTB can order the landlord to stop the harassment, refund any illegal overcharges, and decrease your rent by the surcharge amount once the A/C unit is removed or seasonally turned off.
How Much Does it Cost in Ontario?
Standing up for your rights is relatively inexpensive, but landlords face financial penalties if they act illegally. 💵 Consider the following costs:
- Filing a T-Application: Filing a tenant application at the LTB currently costs $48 CAD online (via the Tribunals Ontario Portal) or $53 CAD in paper. If you win, the landlord usually has to reimburse this fee.
- Seasonal Surcharges: If electricity is included, you must pay the actual or estimated cost of electricity (typically $40 to $80 CAD per month depending on usage). Any arbitrary fees exceeding actual power costs are illegal, and you can seek a refund at the LTB.
- Installation Costs: To ensure the unit is safely and securely installed under the new regulations, you might spend $30 to $60 CAD on proper A/C support brackets.
How Long Does the Process Take?
Dispute resolution is not immediate. ⏱ If you file a T1 or T2 application, it currently takes the LTB anywhere from 6 to 10 months to schedule a hearing. However, while you are waiting for the hearing, you are only legally required to pay your standard, lawful rent. Do not short your base rent to offset the A/C dispute, as this could give the landlord grounds to evict you for non-payment.
| Lease Agreement Terms | Can the Landlord Charge an A/C Fee? |
|---|---|
| Electricity included, NO mention of A/C fees. | Yes. As of July 1, 2026, Section 36.1 allows a seasonal surcharge to cover actual or estimated power costs, unless the lease explicitly prohibits it. |
| Electricity included, Lease specifically lists a $50/month A/C fee. | Yes. You must pay the agreed fee, provided it does not exceed the actual or estimated cost of the electricity. |
| Tenant pays their own electricity (separately metered). | No. You already pay the utility provider directly for the electricity your A/C uses. |
Frequently Asked Questions (FAQ)
Can the landlord physically enter my unit and take my A/C?
Absolutely not. Entering a rental unit without 24 hours written notice (unless it is an emergency) is illegal. Taking your personal property is considered theft and severe harassment under the RTA. You should call the police and file a T2 application if this occurs.
Can the landlord ban window A/C units completely?
Sometimes. Under Section 36.1, tenants have an explicit right to install window or portable A/C units. However, a landlord can legally prohibit installation if it violates local municipal property standards (such as Toronto’s Chapter 629), violates structural safety guidelines, or if the building’s electrical system cannot handle the load. They cannot ban them arbitrarily or purely to save money on electricity.
What if I use a portable floor A/C instead of a window unit?
Portable floor A/C units remove the “falling hazard” associated with window brackets, but the financial rules under Section 36.1 remain exactly the same. Under the RTA, window and portable units are treated identically. If electricity is included in your rent, your landlord has the same legal right to charge a seasonal surcharge to cover the actual or reasonably estimated utility cost of your portable unit.
My landlord says the A/C fee is a new building rule. Is that allowed?
Generally, no. A landlord cannot unilaterally invent arbitrary fees mid-tenancy. However, starting July 1, 2026, Section 36.1 of the RTA grants landlords a statutory right to charge an electricity surcharge for tenant-installed A/C units if electricity is included in your rent. This is a provincial legal right, not a private “building rule,” but the fee must strictly reflect actual or reasonably estimated power costs.
