Updated: August 4th, 2026

Ontario’s rent control landscape is more nuanced than a simple yes-or-no question, and both landlords and tenants frequently misunderstand which rules apply to their specific situation. The 2018 amendment to the Residential Tenancies Act created a division in the rental market that now shapes investment decisions, pricing strategy, and the practical relationship between landlords and tenants in hundreds of thousands of Ontario rental units.

Understanding which side of the November 15, 2018 line your property falls on – and what that actually means for how you manage rent increases, price vacancies, and plan capital expenditures – is fundamental knowledge for every Ontario landlord in 2026. It is equally important for tenants, who often don’t know whether their unit is subject to rent control and therefore whether their landlord’s proposed increase exceeds what the law permits.

This guide covers the complete rent control framework: what the 2018 amendment actually changed, what the exemption means and – critically – what it does not mean, how the Above Guideline Increase process works for rent-controlled units, the strategic and investment implications for Ontario landlords in 2026’s market, how to verify your unit’s control status, and the risks that apply regardless of whether your unit is controlled or exempt.

Ontario’s Rent Control Framework – The Pre- and Post-2018 Division

Units Subject to Rent Control

The RTA’s rent control provisions apply to rental units that were first occupied for residential purposes before November 15, 2018. For these units, the annual rent increase guideline – set by the provincial government each year – is the maximum percentage by which a landlord can increase rent within an existing tenancy.

The 2026 guideline is 2.5%. This was set by the Ministry of Municipal Affairs and Housing in late 2025 and reflects a calculation based on the Ontario Consumer Price Index. For context, the guideline history over recent years:

• 2022: 1.2% (artificially suppressed due to COVID-era freeze) 
• 2023: 2.5% – 2024: 2.5% – 2025: 2.5% – 2026: 2.5%

The guideline applies to rent increases within an existing tenancy. It does not restrict what rent a landlord can charge when a rent-controlled unit is re-rented to a new tenant – in that situation, market rent can be charged to the new tenant, and subsequent increases within that new tenancy are then subject to the guideline from that new base.

Units Exempt From Rent Control

The November 15, 2018 amendment created a rent control exemption for units first occupied for residential purposes on or after November 15, 2018. The legislative intent was to stimulate new rental construction by removing the deterrent that rent control created for new purpose-built rental development. The exemption applies regardless of when you purchased the unit – what matters is when it was first occupied as a rental, not when ownership changed.

• Units typically covered by the exemption: 
  • Newly completed condominium units first occupied after November 14, 2018 
  • New purpose-built rental apartment units completed after that date
  • New secondary suites (basement apartments) in houses where the house itself was first occupied as a dwelling on or after November 15, 2018 
  • Newly constructed laneway houses, garden suites, and other accessory dwelling units
• Units that are NOT exempt, even if they appear “new” to a given landlord: 
  • A condo unit first occupied in 2015 that you purchased in 2023 – the first occupancy date controls, not your purchase date 
  • A renovated basement unit in a house built in 2005, where the basement was first rented in 2019 – the house’s construction date may not be determinative; what matters is when the specific unit was first occupied 
  • A unit that was first occupied before November 15, 2018, became vacant, and was re-rented after that date – a change of tenant does not reset the control status

What the Exemption Actually Means – And What It Doesn’t

What Rent Control Exemption Permits

For exempt units, there is no guideline cap on rent increases within an existing tenancy or between tenancies. A landlord who owns an exempt unit can:

• Set any initial rent when the unit is first rented or re-rented between tenancies
• Increase rent within an existing tenancy by any percentage, not limited to 2.5% 
• Take the unit to market rent at each vacancy without restriction

This flexibility is most significant in rising markets: a landlord of a rent-controlled unit that has been occupied for five years at a rent significantly below current market cannot reset to market rate unless the tenant vacates. A landlord of an exempt unit can increase to market at a natural tenancy turnover, or within the tenancy with proper notice.

What Rent Control Exemption Does NOT Change

This is where many landlords and tenants make serious mistakes. The exemption removes the percentage cap. It does not remove the procedural requirements, frequency limits, or any other RTA obligations.

• 90-day written notice is still required: All rent increases – regardless of whether the unit is rent-controlled or exempt – require a minimum of 90 days’ written notice on the official N1 form before the increase takes effect. You cannot give less notice just because the unit is exempt. A notice delivered 60 days before the intended effective date is invalid, even on an exempt unit.
• Increases are still limited to once every 12 months per tenancy: You can only raise rent once every 12 months within a given tenancy. If you increase rent in March 2026, you cannot increase again until at least March 2027, regardless of the unit’s control status.
• All other RTA obligations remain fully in force: Maintenance obligations, entry rules, quiet enjoyment, proper eviction process, LTB procedures – none of these are affected by rent control status. Exempt units are not “deregulated” in any broader sense; they simply have no guideline cap on increase percentages.
• The N1 form requirement applies: Even for an exempt unit, a rent increase notice must be served on the official N1 form. A letter or email stating “your rent is increasing by 15% effective January 1” is not valid notice regardless of whether the unit is exempt.

The Above Guideline Increase (AGI) Process for Rent-Controlled Units

For landlords with rent-controlled units who need to exceed the rent increase 2.5% guideline – due to significant capital expenditures or extraordinary cost increases – the Above Guideline Increase process provides a formal mechanism for applying to the LTB for an above-guideline increase.

Who Can File and When

Any landlord of a rent-controlled residential unit can file an L5 AGI application at the LTB. The application must be based on one of the qualifying grounds set out in the RTA. There is no deadline for filing after the qualifying expenditure occurs, but the AGI will only be effective prospectively from the effective date ordered by the LTB.

Qualifying Grounds for an AGI

Extraordinary increases in municipal taxes or charges: If your property tax increased by more than the guideline percentage in a given year, you may be able to include that excess increase as a ground for an AGI. The LTB will calculate the proportion of the tax increase that justifies above-guideline rent recovery.

• Significant capital expenditures (capital repairs): Major repairs to or replacements of major components of the building – not individual units – that are necessary to maintain the building and that the LTB classifies as qualifying capital expenditures. This includes work such as new roofing, new windows for the entire building, new elevators, major plumbing infrastructure, new HVAC systems serving common areas, foundation work, and exterior cladding replacement. The key point: the work must be to building-wide systems or components, not individual unit improvements or renovations.
• Significant increases in operating costs for security services: If your security costs have increased significantly due to changes in the level of security service provided (not simply due to inflation on existing services), this may qualify.

What Does NOT Qualify for an AGI

Normal maintenance and routine repairs are not capital expenditures for AGI purposes. Individual unit renovations and upgrades do not qualify. General cost increases due to inflation – which is what the annual guideline is designed to compensate for – do not qualify as extraordinary increases. The bar for a qualifying AGI application is genuinely significant capital work on building systems, not year-to-year operating cost fluctuations.

The AGI Process

Filing an AGI requires completing an L5 Application form and supporting it with detailed documentation of the qualifying expenditures. All affected tenants must be served with a copy of the application and have the right to participate in the hearing and challenge the landlord’s claims. The hearing is adversarial – tenants can and do challenge the classification of expenditures, dispute cost figures, and raise issues about the building’s condition. Professional representation is strongly recommended for significant AGI applications.

The LTB will issue an order specifying the percentage increase approved, the rental periods it applies to, and any phasing (AGI increases are sometimes applied over multiple years to reduce the per-year impact on tenants).

Strategic Implications for Ontario Landlords in 2026

For New Investors Considering Purchase

The rent control status of a unit you’re considering purchasing is a material factor in your property investment analysis. An exempt unit provides pricing flexibility that a rent-controlled unit does not – but the significance of that flexibility depends on several factors:

• Current rent vs market rate: If a rent-controlled unit is priced at or near market rent, the control status matters less practically. The constraint becomes acute when rent has been significantly suppressed below market through a long tenancy – common in units with multi-year or decade-plus tenancies started at lower rents.
• Turnover expectations: If you expect high turnover in the unit (which is more common in urban high-rise condos than in suburban family homes), the ability to reset to market at each turnover is regularly exercisable. If you expect long, stable tenancies, the exemption may never come into play in the way you anticipate.
• Capital expenditure planning: For a rent-controlled unit with significant capital work needed, an AGI application may provide a path to above-guideline recovery – but only if the work qualifies and is properly documented.

For Landlords With Mixed Portfolios

Landlords who own both rent-controlled and exempt units should apply different management strategies to each:

• Rent-controlled units: Apply the annual guideline increase every year without exception – the 90-day notice must be served with enough lead time for a January 1 (or other standard) effective date, and the calendar commitment requires tracking. Missing a year doesn’t allow you to “bank” the increase and apply a double increase the following year. Each year’s guideline increase is a separate entitlement that must be exercised in that year.
• Exempt units: Track current market rents for comparable units in your area and model increases accordingly. The 90-day/12-month procedural requirements still apply, but the percentage is a business decision rather than a regulated figure. Rents that have fallen significantly behind market on exempt units can be brought to market at a natural tenancy turnover without restriction.

Our rent collection service tracks guideline changes annually, prepares compliant N1 notices with proper timing, and maintains the rent increase records that protect you from tenant challenges on both controlled and exempt units.

Verifying Whether Your Unit Is Rent-Controlled

The fundamental question – when was this unit first occupied for residential purposes – is not always easy to answer. Here are the reliable sources:

• Building permit records: Contact the municipality and request the building permit records for the property. The permit will show when construction was approved and typically when the occupancy permit was issued.
• Occupancy permit: The formal occupancy permit issued by the municipality for a newly constructed building or unit shows the date the building was permitted for occupancy – typically shortly before or upon first residential occupancy.
• Property tax records: The unit’s first assessment as a residential property (which triggers residential property taxes) typically follows closely on first occupancy. Historical tax assessment records can be obtained from MPAC (Municipal Property Assessment Corporation).
• Land registry records: The first registration of the unit as a condominium on the land registry – for condominiums – typically precedes first occupancy by a short period.
• The Status Certificate: For condominium units, the Status Certificate includes information about the corporation that can help establish the corporation’s registration date, providing a floor on the potential occupancy date.

When the date is genuinely uncertain and the amount is significant, a paralegal with experience in rent control matters can help analyze the available records and reach a defensible conclusion about the unit’s status.

Frequently Asked Questions

Q: If I renovate a vacant rental unit extensively, does it become exempt from rent control? 

No. The rent control status of an existing unit is determined by when it was first occupied as a residential rental – not by whether it was subsequently renovated or how extensively. A unit first occupied in 2015 that you completely gut-renovated in 2023 remains subject to rent control. The exemption applies only to units where the first-ever residential occupancy occurred on or after November 15, 2018.

Q: Can I charge any amount of rent on an exempt unit when a new tenant moves in? 

Yes. There is no restriction on the rent you can set for a new tenancy in an exempt unit. The unit’s first rent with a new tenant is a pure market negotiation between you and the prospective tenant. Once that rent is set and the tenancy begins, subsequent increases within that tenancy are subject to the 90-day/12-month procedural requirements – though not to any percentage cap on exempt units.

Q: What happens if I exceed the guideline on a rent-controlled unit without an AGI? 

A tenant who receives an above-guideline increase on a rent-controlled unit without an approved AGI can file a T1 Application at the LTB. The LTB will order you to rebate the excess increase to the tenant for every month it was collected, reduce the rent going forward to the guideline-compliant amount, and potentially pay the tenant’s LTB filing costs. The financial exposure from an inadvertent above-guideline increase on a rent-controlled unit can be significant if it goes undiscovered for multiple years before the tenant files.

Q: The 2026 guideline is 2.5% – can I apply it to an exempt unit? 

Yes – you can apply any percentage to an exempt unit, including the guideline percentage. Some landlords use the guideline as a reference benchmark even when not legally required to, as a modest and defensible annual increase that is unlikely to provoke tenant conflict. Others apply higher increases on exempt units where the rent has fallen significantly below market. The 2.5% figure is a maximum for controlled units and a reference for exempt ones, not a ceiling in either direction for exempt units.

Q: Can a tenant challenge a rent increase on an exempt unit? 

A tenant can always challenge whether the N1 notice was procedurally valid – whether it gave 90 days’ notice, whether it was on the correct form, whether it was properly served. If the notice has a procedural defect, the increase may be void on those grounds regardless of the unit’s control status. What a tenant of an exempt unit cannot challenge is the percentage of the increase, provided the procedural requirements were met.

Q: What is the rent increase guideline for 2026 and how was it set? 

The 2026 guideline is 2.5%, set by the provincial government based on the Ontario Consumer Price Index for the relevant calculation period as specified in the RTA. The guideline is typically announced in late fall of the preceding year. For units first occupied before November 15, 2018, this is the maximum within-tenancy increase that can be applied without an AGI application. It does not restrict what rent can be charged to a new tenant at a new tenancy, even on rent-controlled units.

Manage Rent Increases Compliantly Across Your Portfolio

Whether your units are rent-controlled or exempt, the administrative requirements for rent increases are substantial and procedurally unforgiving. A missed form requirement voids the increase even when the underlying increase is legally permitted.
