Ontario rent control has never been more important — or more misunderstood. With rents still elevated across the province, knowing exactly what the rules are could save you thousands of dollars or prevent a costly legal dispute.
Ontario rent control limits how much a landlord can increase rent for an existing tenant in a given year. The allowable increase is set annually by the provincial government as the Rent Increase Guideline — based on the Ontario Consumer Price Index for the prior year.
For 2026 the Ontario rent increase guideline is 2.5%. This means landlords of rent-controlled units can raise rent by a maximum of 2.5% with proper 90-day written notice. Any increase above this amount requires approval from the Landlord and Tenant Board.
This is where most tenants get confused. Ontario rent control applies only to residential units that were first occupied for residential purposes before November 15, 2018. Units that were new or first occupied after this date are exempt from rent control — meaning landlords of newer buildings can raise rent by any amount between tenancies or with sufficient notice.
Even for rent-controlled units, Ontario law allows landlords to apply for Above-Guideline Increases (AGIs) in specific circumstances. An AGI application is made to the Landlord and Tenant Board and may be approved when the landlord has completed major capital expenditures, experienced extraordinary increases in property taxes or utility costs, or faces other qualifying cost increases.
Capital expenditure AGIs can allow rent increases of several percentage points above the guideline and can continue for up to 3 years. Tenants have the right to oppose AGI applications at a hearing and should consider consulting a tenant duty counsel or tenant advocacy organization before signing any AGI agreement.
Ontario landlords must provide tenants with at least 90 days written notice of any rent increase using the approved N1 form. The increase can only take effect on the first day of a rental period — typically the first of the month. Rent can only be increased once every 12 months per tenancy, regardless of the unit's rent control status.
If your landlord attempts to increase your rent above the guideline without an approved AGI, or without proper notice, you have the right to refuse the illegal portion of the increase. You can file an application with the Landlord and Tenant Board to have the illegal increase reversed and potentially receive a rent rebate.
The LTB processes thousands of rent increase disputes annually in Ontario. Filing an application costs $53 for tenants and the process is accessible without a lawyer through the tribunal's self-help resources. Community Legal Clinics across Ontario also provide free legal advice to tenants on rent-related matters.
Ontario's rent control rules are widely misunderstood, and knowing exactly how they apply to your unit is essential for both tenants and anyone budgeting for housing costs. The province sets an annual rent increase guideline that caps how much a landlord can raise the rent on most existing tenancies each year.
The key distinction in Ontario is the date the unit was first occupied. Rental units first occupied for residential purposes on or after November 15, 2018 are exempt from the annual rent increase guideline, meaning landlords can raise rent on these newer units by any amount between tenancies and, in many cases, during them with proper notice. Units occupied before that date generally remain subject to the guideline, which limits annual increases to a capped percentage tied to inflation.
For rent-controlled units, a landlord can normally raise the rent only once every twelve months, must provide at least 90 days written notice using the proper form, and cannot exceed the provincial guideline without approval from the Landlord and Tenant Board for specific allowable reasons such as major capital expenditures. Understanding which category your unit falls into is the single most important factor in predicting your future housing costs.
Ontario's Residential Tenancies Act establishes a framework of rights and responsibilities for both tenants and landlords, and knowing yours protects you from both unfair treatment and inadvertent lease violations. Tenants who understand the rules are far better positioned to handle disputes and avoid costly mistakes.
Tenants have the right to a safe, well-maintained home, and landlords are responsible for repairs and maintaining the unit in a good state of repair regardless of whether the tenant knew about issues before moving in. Tenants are entitled to reasonable privacy: a landlord must generally provide 24 hours written notice before entering, except in emergencies. Tenants also have strong protection against eviction — a landlord cannot simply force a tenant out, but must follow the formal process through the Landlord and Tenant Board, with eviction only for specific legal reasons.
Tenants are responsible for paying rent on time, keeping the unit reasonably clean, repairing damage they or their guests cause beyond normal wear and tear, and not disturbing other tenants. Understanding these obligations prevents the lease violations that can lead to legitimate eviction proceedings. The Landlord and Tenant Board handles disputes between the parties, and tenants facing issues can apply to the Board, often with help from community legal clinics that assist Ontario tenants at no cost.
One area of frequent confusion is the deposit. In Ontario, a landlord can collect a rent deposit equal to one month's rent (or one week for weekly tenancies), but this must be applied to the last month of the tenancy — it is not a damage deposit, and landlords cannot legally collect a separate security or damage deposit. The landlord must also pay annual interest on the rent deposit at the rent increase guideline rate. Knowing these specific rules prevents tenants from being charged amounts they do not actually owe.
With rents in much of Ontario consuming a large share of household income, budgeting realistically for housing is one of the most important financial skills for renters in the province. The traditional guideline of spending no more than 30% of gross income on housing is increasingly difficult to achieve in cities like Toronto, Ottawa, and Kitchener-Waterloo, where market rents often push tenants well above that threshold.
A more practical Ontario-specific approach is to budget based on net take-home pay rather than gross income, since the difference after tax, CPP, and EI is substantial. Aiming to keep rent below roughly 35% of net income provides a more realistic target, though many Ontario renters in expensive markets exceed even this out of necessity. The higher your rent-to-income ratio, the less room remains for savings, debt repayment, and unexpected expenses, which is why housing cost is the dominant financial stress factor for many Ontario households.
Practical responses to high rents include sharing accommodation, which can roughly halve per-person housing costs; considering secondary cities with transit links to employment centres; and negotiating at lease renewal, particularly in rent-controlled units where the guideline limits increases. For tenants in newer, non-rent-controlled buildings, budgeting for potential large increases at renewal is essential to avoid being caught off guard.
Renters should also remember that staying in a rent-controlled unit can be financially valuable over time, since the capped annual increases mean a long-term tenant may pay well below current market rent. Weighing the savings of staying put against the desire to move is a genuine financial consideration in Ontario's market. Building an emergency fund is especially important for renters, since a job disruption with high fixed rent and no equity cushion can escalate quickly — a few months of housing costs set aside provides crucial security.
Q: Can a landlord raise rent to market rate when a new tenant moves in?
A: Yes — for both controlled and uncontrolled units, landlords can set any rent amount at the start of a new tenancy. Rent control only limits increases during an existing tenancy. This is why many Ontario landlords prefer tenant turnover — they can reset rent to current market rates with each new tenancy.
Q: Does rent control apply to basement apartments in Ontario?
A: Rent control rules apply to basement apartments the same way they apply to other rental units — based on the date the unit was first occupied. A basement apartment created and first rented before November 15, 2018 is rent controlled. One first rented after that date is exempt.
Q: What is the 2026 Ontario rent increase guideline?
A: The Ontario rent increase guideline for 2026 is 2.5%. This applies to rent-controlled units — those first occupied before November 15, 2018. The guideline is announced by the provincial government each year based on the Ontario Consumer Price Index. Landlords must give 90 days written notice before any rent increase takes effect.
