Yes, an Ontario landlord can generally require you to remove a window Air Conditioning (AC) unit during the winter. This is lawful if it is written into your Standard Form of Lease, if the unit causes property damage (like drafts freezing the building’s water pipes), or if it violates local municipal property standards.
When the bitter cold of winter arrives in cities like Ottawa, Sudbury, or Toronto, keeping a rental apartment warm becomes the top priority. Many tenants leave their bulky window Air Conditioning (AC) units installed year-round simply out of convenience. However, this often triggers conflict with the property manager. You may return home to find a formal notice demanding you immediately remove the AC unit from your window, leaving you wondering if the landlord actually has the power to dictate what sits on your windowsill.
Under the Residential Tenancies Act (RTA), tenants have the right to reasonable enjoyment of their unit, but landlords also have a strict legal duty to maintain the structural integrity and energy efficiency of the building. A poorly insulated window AC unit can let in freezing drafts, leading to burst pipes and skyrocketing heating bills. If your landlord is threatening eviction over an AC unit, understanding your rights and reviewing your lease is crucial.

Step-by-Step Guide to Handling an AC Removal Demand
If your landlord demands you remove your window AC unit in November, ignoring the request is a dangerous strategy. Landlords can escalate this to the Landlord and Tenant Board (LTB) if they believe you are damaging the property. Follow these steps to resolve the issue legally and safely.
Step 1: Check Your Standard Form of Lease
Since 2018, most Ontario tenancies require a standardized lease agreement. Check the “Additional Terms” appendix of your lease. Many corporate landlords include a specific, legally binding clause stating that all window AC units must be removed by October 31st and cannot be reinstalled until May. If you signed a lease containing this seasonal clause, you are generally legally bound to obey it. 🔍
Step 2: Assess Safety and Damage Risks
Even if your lease says nothing about winter removal, the landlord can intervene if the unit is causing damage. Does the AC unit prevent the window from closing and locking properly, violating municipal security bylaws? Is freezing air blowing directly onto a radiator or water pipe? If the installation threatens the building’s infrastructure, the landlord has a valid legal reason under the RTA to demand its immediate removal.
Step 3: Respond to an N5 Notice
If you refuse a verbal or emailed request, the landlord’s next step is serving you an official LTB form called an N5 (Notice to Terminate a Tenancy for Interfering with Others, Damage or Overcrowding). Do not panic. An N5 gives you a mandatory 7-day “void” period. If you simply remove the AC unit within those 7 days, the eviction notice becomes completely void and the landlord cannot take you to court. 🗂
Step 4: Request Maintenance Assistance
Window AC units are heavy, and removing them from a high-rise apartment in Mississauga or London can be incredibly dangerous. If you are elderly, disabled, or simply fear dropping the unit onto the sidewalk below, write an email to your landlord requesting their maintenance staff assist you with the removal. Many landlords will gladly send a superintendent to do this safely rather than risk a pedestrian injury.
Step 5: Winterize the Unit if Removal is Impossible
In rare cases, an AC unit is bolted into a custom wall sleeve (through-the-wall AC) and cannot be easily removed. If this is the case, you must communicate this clearly to the landlord in writing. Propose a compromise, such as purchasing a heavy-duty, insulated winter cover for the exterior of the AC unit to stop drafts. If the landlord rejects a reasonable compromise, the LTB will have to decide the matter at a hearing. 📝
When Can a Landlord Demand AC Removal?
Understanding the difference between a valid safety concern and an arbitrary landlord rule is essential for Ontario tenants.
| Reason for Demand | Is the Demand Legal in Ontario? | Explanation |
|---|---|---|
| Explicit Lease Clause | Yes. | If the lease clearly states seasonal removal dates, it is an enforceable contract term. |
| Drafts / Energy Waste | Yes. | If the landlord pays for the heating (gas/hydro), they can enforce removal to prevent extreme energy waste. |
| Safety Hazard / Falling Risk | Yes. | If the unit is not secured properly and risks falling onto the street in winter winds. |
| Aesthetic Reasons (“It looks ugly”) | No. | A landlord generally cannot force removal purely because they don’t like how it looks from the outside, absent specific condo bylaws. |
What Are the Costs Involved?
Ignoring an AC dispute can end up hitting your wallet hard.
- LTB Filing Fees: If the landlord is forced to file an L2 application against you at the LTB, they may ask the adjudicator to order you to pay their $201 CAD filing fee.
- Damage Claims: If your AC unit lets in freezing air that bursts a water pipe, the landlord can sue you for the repair costs, which can easily exceed $5,000 CAD.
- Hydro Bills: If you pay your own electricity and heating, leaving an uninsulated AC unit in the window all winter can increase your personal heating bill by $50 to $100 CAD per month due to heat loss.
How Long Does the Process Take?
Timelines escalate quickly once formal notices are served.
- N5 Notice Period: An N5 notice provides you with exactly 7 days to correct the behaviour (remove the AC) to void the eviction notice.
- LTB Hearing: If you refuse to remove it and the landlord files for an eviction hearing, waiting for an LTB date typically takes 4 to 8 months due to provincial backlogs.
- Safe Installation/Removal Window: Most standard Ontario leases mandate that AC units be removed by October 31st and not reinstalled until May 15th or June 1st.
Frequently Asked Questions (FAQ)
Can the landlord enter my apartment and remove the AC themselves?
No. A landlord cannot forcefully enter your unit and dismantle your personal property without your permission or an explicit LTB order. They must provide 24 hours written notice to enter, and even then, they cannot physically force you to remove your belongings during that entry.
What if I have a portable floor AC unit with a window hose?
Landlords generally prefer portable floor units because they are much safer and do not pose a falling hazard. However, you should still remove the plastic exhaust hose from the window during winter to allow the window to fully close and lock, keeping out the cold.
Can my landlord charge me a seasonal fee just for having an AC?
In Ontario, a landlord can only charge an extra AC fee if the landlord pays for the electricity AND this specific seasonal fee was explicitly agreed upon in your original lease. They cannot suddenly invent a new fee mid-tenancy.
What happens if the building turns the heat up too high in the winter?
Many older buildings run their boilers extremely hot, causing tenants to open windows or run ACs in December. If the landlord demands AC removal, but your unit is dangerously hot, you can file a T2 application with the LTB for interference with your reasonable enjoyment.
If I live in a Condo, do different rules apply?
Yes. If you rent a condominium unit, you are bound by both the RTA and the Condominium Act. The Condo Board’s specific bylaws regarding the exterior appearance of the building trump standard rental rules, and they can absolutely ban window AC units outright.
