Determining if Your Rental Unit is Exempt from Rent Control

Rent & Deposits Ontario 5 min read · published October 13, 2026 Flag of Ontario

How Ontario rent control generally works

Ontario's Residential Tenancies Act, 2006 sets rules for rent increases in most residential tenancies.[1] For rent-controlled units, a landlord generally must wait 12 months between increases, give written notice in the required form, and stay within the annual guideline unless the Landlord and Tenant Board approves an above-guideline increase. The applicable guideline can change each year, so check the current official amount before assessing a notice.

Rent control limits the amount of a regular annual increase, but it does not freeze rent permanently. A landlord may also be able to charge a new market rent after a tenant voluntarily leaves, subject to the rules that apply to the next tenancy.

Rent control usually concerns the amount and timing of increases, not whether a tenancy is covered by Ontario's residential tenancy law.

When a rental unit may be exempt

The most common Ontario exemption applies to units first occupied for residential purposes after November 15, 2018.[2] This date is about the first residential occupancy of the unit, not necessarily the date you moved in or the date your lease was signed. A basement apartment, condominium, house, or other self-contained unit may be exempt if it meets the timing requirement.

Ask the landlord when the unit was first occupied as a residence and keep the answer in writing. You can also look for earlier listings, municipal records, utility information, or statements from prior occupants, but do not assume that a unit is exempt simply because the landlord says so.

Other situations can involve different rules, including certain social or specialized housing arrangements, care homes, and units where the tenant shares a kitchen or bathroom with the owner in circumstances covered by the legislation. Whether an exception applies depends on the facts, so review the Act or obtain advice before accepting an exemption.

Questions to ask before signing or paying an increase

  • When was the unit first occupied for residential purposes?
  • Does the written rental agreement state why the landlord believes the unit is exempt?
  • What records or documents support the claimed exemption?
  • What rent amount and increase date are shown in the proposed notice?
Keep copies of the lease, notices, messages, and rent receipts in one secure place.

How to check an exemption

Start by comparing the unit's first residential occupancy date with November 15, 2018. The date may be unclear in a newly renovated or converted property, so distinguish between construction, renovation, and actual residential occupancy. A landlord's renovation date alone does not automatically establish an exemption.

Next, identify the type of arrangement. Confirm whether you rent a self-contained unit, share a kitchen or bathroom with the owner, live in a rooming or care setting, or occupy housing with a special funding or ownership structure. These details can affect which parts of the Act apply.

If the answer remains disputed, the Landlord and Tenant Board can determine whether the Act applies. The tenant can use Form A1: Application about Whether the Act Applies to ask the Board to decide this issue. Read the form instructions carefully, serve the application as required, and keep proof of service.

A written decision from the Landlord and Tenant Board can resolve uncertainty about coverage and rent increase rules.

What to do after receiving a rent increase notice

Check the notice date, effective date, proposed rent, and form used by the landlord. For a rent-controlled unit, the landlord normally uses Form N1: Notice of Rent Increase and must provide at least 90 days' notice in most monthly or yearly tenancies.[3] Compare the percentage increase with the current Ontario guideline and check whether the landlord says an above-guideline application has been approved.

If your unit is exempt, the annual guideline may not limit increases in the same way, but the landlord still must follow the lease, provide any legally required notice, and comply with rules against bad-faith conduct or unlawful interference. An exemption does not give a landlord permission to change the rent whenever or however they wish.

Do not ignore a notice or stop paying rent without legal advice. If you believe the increase is unlawful, write to the landlord explaining your position, continue keeping records, and contact the Board or a community legal clinic promptly.

Evidence that may help

  • Save the rental agreement, rent payment records, and every rent increase notice.
  • Keep messages in which the landlord discusses the unit's age or first occupancy.
  • Record the dates when notices were delivered and when increases are supposed to begin.
  • Bring organized documents to any Landlord and Tenant Board hearing or application.

FAQ

How can I tell if my Ontario rental unit is exempt from rent control?
Check when the unit was first occupied for residential purposes and whether a specific statutory exception applies. Units first occupied for residential purposes after November 15, 2018 are commonly exempt from the annual guideline.
Does a new lease make an older unit exempt?
No. The date a new tenant signs a lease is not usually the test. The relevant question is generally when the unit was first occupied for residential purposes.
Can my landlord raise the rent by any amount if the unit is exempt?
An exemption from the annual guideline does not remove every legal limit. The landlord must still follow the lease, required notice rules, and other applicable provisions of Ontario law.
What form can I use if I dispute whether the Act applies?
A tenant can consider Form A1, Application about Whether the Act Applies, through the Landlord and Tenant Board. Follow the form's instructions about filing and serving the application.

How-To: Check whether your unit is exempt

  1. Gather your lease, rent notices, payment records, and messages about the unit.
  2. Ask for the date when the unit was first occupied for residential purposes.
  3. Compare that information with the November 15, 2018 rent control threshold and review any claimed exception.
  4. Check the increase notice, effective date, amount, and form against Ontario requirements.
  5. If the issue remains disputed, review Form A1 and consider applying to the Landlord and Tenant Board.

Key Takeaways

  • The unit's first residential occupancy date is often central to the exemption question.
  • An exempt unit may not be limited by the annual rent guideline, but other legal rules still apply.
  • Written records can help establish the unit's history and challenge an incorrect increase.
