How the 2018 Rent Control Exemption Affects New Builds and Basement Additions in Ontario

As of May 2026, Ontario rental units first occupied for residential purposes after November 15, 2018, are legally exempt from provincial rent control. Landlords of these exempt units can raise the rent by any amount they choose, provided they give a 90-day written notice using an N2 form.

Renting a modern condominium in Toronto or a newly renovated basement apartment in Mississauga can be an exciting prospect. However, many tenants are completely unaware of a critical exemption hidden within the Residential Tenancies Act (RTA).

If you live in a newer building, your landlord may not be bound by the province’s annual rent increase guideline. 📍 Understanding the November 15, 2018, rent control exemption is essential for predicting your future housing costs and avoiding unexpected financial shocks.

Step-by-Step Process for Determining Rent Control Status in Ontario

Navigating the rules surrounding new builds and newly finished basements can be confusing. The deciding factor is not when the building was constructed, but rather when it was first lived in for residential purposes.

If your landlord attempts to double your rent, you must verify their legal right to do so before paying. 📝 Here is a step-by-step guide to confirming your unit’s status and protecting your rights.

Step 1: Verify the Date of First Occupancy

The golden rule in Ontario is the date November 15, 2018. If anyone (a previous tenant, the owner, or a guest) lived in the residential unit before this date, the unit is rent-controlled.

If the space was a raw, unfinished basement before 2019, and the landlord just built an apartment there, it is generally exempt from rent control, even if the main house is 50 years old. 📅 You must establish the precise timeline of when the space became residential.

Step 2: Review the Notice of Rent Increase Form

By law, a landlord must provide you with a 90-day written notice before raising your rent. Look closely at the Landlord and Tenant Board (LTB) form they used.

A rent-controlled unit requires an N1 form, which restricts the increase to the provincial guideline (usually around 2.5%). 👀 An exempt unit requires an N2 form, which allows the landlord to fill in literally any dollar amount they desire.

Step 3: Request Proof of the Exemption

If you receive an N2 form and suspect your unit is actually older than 2018, write a polite but firm email to your landlord asking for proof of the exemption.

They should be able to produce building permits, an occupancy permit from the municipality, or previous leases showing the unit was created after the cutoff date. 💼 A reputable property management firm will have these documents readily available.

Step 4: Continue Paying Your Current Lawful Rent

If you genuinely believe the landlord is using the wrong form and illegally attempting to bypass rent control, do not simply agree to the new rate.

You are only legally obligated to pay your current, lawful rent until the Landlord and Tenant Board officially rules otherwise. 🚨 However, you must be absolutely certain about the occupancy date before withholding the increased amount, or you could face an N4 eviction notice for arrears.

Step 5: File an Application with the LTB if You Disagree

If there is a fundamental dispute about whether the basement addition or new condo is exempt, you can force a legal determination. You or your lawyer can file an A1 Application (Application About Whether the Act Applies) with the LTB.

An adjudicator will review the building permits and historical evidence to rule whether the unit falls under the 2018 exemption. ✅ This ruling settles the matter permanently for the unit.

How Much Does it Cost in Ontario?

Challenging an illegal rent increase is relatively inexpensive, but facing an uncontrolled rent hike can cost you thousands of dollars annually.

  • LTB Filing Fee: Filing an A1 or T4 application costs roughly $53 CAD for a tenant using the online portal.
  • Paralegal Representation: If you hire a legal professional to represent you at the LTB, fees typically range from $800 to $1,500 CAD.
  • The Cost of Exemption: If the unit is legally exempt, a landlord could theoretically increase a $2,000 CAD rent to $3,000 CAD per month, as there is no legal maximum limit.

How Long Does the Process Take?

Regardless of whether the unit is exempt or controlled, the landlord must provide a full 90 days of written notice before any rent increase takes effect.

If you file an application to dispute the exemption at the LTB, getting a hearing date in busy jurisdictions like Toronto or Ottawa currently takes between 6 to 10 months. ⌛ You continue to pay your old rent rate during this waiting period.

Frequently Asked Questions (FAQ)

Does the exemption apply if the landlord just renovated the kitchen?

No. Cosmetic renovations, such as installing a new kitchen, flooring, or bathroom in an older apartment, do not exempt the unit from rent control. The exemption only applies to brand new buildings, additions, or newly created residential spaces (like finishing a raw basement).

Can I negotiate a massive rent increase in an exempt unit?

Yes, you can absolutely try to negotiate with your landlord. If they issue a 30% rent increase, you can remind them of the cost of finding a new tenant and offer a 5% increase instead. However, they are under no legal obligation to accept your counteroffer.

What if a basement was lived in illegally before 2018?

The RTA focuses on whether the space was occupied for residential purposes, not whether it was legally permitted by the municipality. If a tenant lived in the unpermitted basement in 2017, the unit is generally subject to rent control, even if the landlord only got the legal permits in 2020.

How often can a landlord raise the rent on an exempt unit?

Even though there is no limit to the dollar amount, the landlord can still only raise your rent once every 12 months. They cannot raise your rent halfway through your first-year lease, nor can they raise it multiple times in a single year.
