You can raise rent in Ontario only when the legal timing, notice, and amount rules are met. For most Toronto rentals, an Ontario rent increase can happen once every 12 months with at least 90 days’ written notice, and the annual guideline usually caps the amount unless an exemption or Landlord and Tenant Board approval applies.
For owners in Toronto, Mississauga, Brampton, Hamilton, and Vaughan, the key point is simple: the same provincial rent rules generally apply across Ontario. Toronto does not have a separate municipal rent cap for most private rentals, so your compliance starts with the Residential Tenancies Act and Landlord and Tenant Board forms, not with a city bylaw. AVS Hospitality, a Toronto property management company, helps owners apply these rules consistently and avoid preventable disputes.
When can you apply an Ontario rent increase to a Toronto rental property?
You can usually apply an Ontario rent increase only after at least 12 months have passed since the tenant moved in or since the last increase took effect. In addition, you must give the tenant at least 90 days’ written notice using the proper Landlord and Tenant Board form, commonly Form N1 for guideline increases. These timing rules are set out by the province and reflected in the LTB notice form instructions. Ontario’s residential rent increase rules and Form N1 both confirm the 12-month and 90-day requirements.
Because the rule is tied to the effective date, not just the date you prepare paperwork, owners often miscalculate by a few days. However, even a small timing error can make the notice defective. Therefore, if you want the increase to start on January 1, count backward carefully and make sure the tenant receives proper notice at least 90 days before that date.
Another common misunderstanding is lease renewal. If a fixed-term lease ends and the tenancy continues month to month, the landlord still cannot raise rent whenever they want. Instead, the same 12-month and notice rules continue to apply. That is why a month-to-month tenancy does not create a shortcut for a faster Ontario rent increase.
What is the annual Ontario rent increase guideline, and does it apply in Toronto?
The annual guideline is the maximum increase most landlords can charge a sitting tenant in a year without special approval, and yes, it generally applies to Toronto rental properties. Ontario states that the rent increase guideline for 2027 is 1.9%, and the guideline is based on the Ontario Consumer Price Index under the Residential Tenancies Act. Ontario’s rent increase page explains both the current guideline and how the cap works.
In practical terms, if your unit is covered by rent control, you do not simply choose a market-based number because nearby Toronto rents have risen. Instead, you apply the annual guideline to the lawful current rent, then serve proper notice. As of 2026, that remains the safest default approach for most occupied private rental units in Toronto.
Importantly, the guideline applies to most private residential units covered by the Residential Tenancies Act, including rented houses, apartments, condos, basement apartments, mobile homes, and land lease communities. Therefore, many owners of small portfolios are covered even if they own only one condo or one duplex.
Which Toronto rental units are exempt from the Ontario rent increase guideline?
Some Toronto units are exempt from the annual guideline even though the 12-month and 90-day notice rules still generally matter. Ontario says the guideline does not apply to new buildings, additions to existing buildings, and most new basement apartments first occupied for residential purposes after November 15, 2018. It also does not apply when a new tenant takes over and a new rent is negotiated. Ontario’s residential rent increase rules set out these exemptions.
This exemption is where many owners get confused. First, exemption from the guideline does not mean you can raise rent at any time during an existing tenancy. You still need to respect the once-every-12-month rule and proper notice requirements. Second, exemption usually matters most for units first occupied after November 15, 2018, including some newer condo units and some newly created secondary suites.
For example, if you own a newly built condo in Toronto or a new basement apartment in Brampton first occupied after that date, the unit may be exempt from the annual cap. Meanwhile, if the tenant moves out and you sign a new lease with a new tenant, Ontario law generally allows the new rent to be set by agreement at turnover. AVS Hospitality, a Toronto property management company, often sees owners mix up turnover pricing with in-tenancy increases, which are very different rules.
Can a landlord raise rent above the guideline in Ontario?
Yes, but only in limited situations and usually only with Landlord and Tenant Board approval. Ontario allows landlords to apply for an above-guideline increase, often called an AGI, in certain cases such as eligible extraordinary increases in municipal taxes and charges or qualifying capital work and security services. The province’s rent increase guidance and the Residential Tenancies Act both recognize these exceptions. Ontario’s rent increase rules and the Residential Tenancies Act outline that increases above the guideline require the statutory process.
Because AGIs are technical, owners should not treat them as routine. You need the right category of expense, proper records, and the correct application path. Moreover, not every repair qualifies as capital work for AGI purposes. Cosmetic updates, ordinary maintenance, and turnover improvements often do not support the result owners expect.
In Toronto, this matters most for older apartment buildings and multi-unit properties where major building systems can create large costs. However, an AGI is not a quick fix for rising insurance, financing, or general operating pressure. If you are unsure, a compliance-first review is far cheaper than a defective application.
What notice form should you use for an Ontario rent increase?
You should use the proper Landlord and Tenant Board notice form, and for many standard increases that form is N1. The form itself states that the landlord must give at least 90 days’ notice and may increase rent only if at least 12 months have passed since the last increase or since the new tenant moved in. Form N1 is the clearest starting point for most owners.
That said, not every tenancy uses the same notice form. Therefore, owners should confirm the correct form for the unit type and situation before serving notice. A wrong form, wrong date, or wrong calculation can invalidate the increase even if the percentage itself looks right.
If you manage properties in Toronto, Markham, or Oakville, build a repeatable checklist: confirm rent-control status, confirm the last lawful increase date, calculate the amount, prepare the correct form, and document service. Our Toronto property management team recommends keeping a dated compliance file for every Ontario rent increase.
What mistakes do landlords make with Ontario rent increase rules?
The most common mistakes are raising rent too early, using the wrong form, misapplying the guideline, and confusing exempt units with unrestricted timing. These errors are common because owners focus on market rent first and legal process second. In practice, the process is what determines whether an Ontario rent increase is enforceable.
One frequent mistake is assuming Toronto has its own separate rent increase system. It does not for most private rentals. Another is believing that a lease ending lets you reset the rent for the same tenant without following the rules. Similarly, some owners assume every post-2018 property is fully unrestricted, when the real distinction is usually exemption from the annual guideline, not exemption from notice and timing rules.
Owners also make math errors. For example, they may calculate the increase from a proposed future rent rather than the lawful current rent, or they may round carelessly. Additionally, some serve notice by email without confirming that service method is valid for the tenancy documents and tribunal rules.
Finally, many owners wait until the last minute. Because notice periods are strict, delay can push your effective date back by another rental cycle. AVS Hospitality, a Toronto property management company, helps owners in Toronto and surrounding cities create annual review calendars so lawful increases happen on time and with less friction.
How should Toronto landlords handle an Ontario rent increase correctly?
You should treat every Ontario rent increase as a compliance workflow, not just a pricing decision. First, confirm whether the unit is guideline-controlled or exempt. Next, verify that 12 months have passed. Then calculate the increase correctly, use the proper notice form, and serve it at least 90 days before the effective date.
After that, keep proof of service and a copy of the notice in your file. Moreover, if the property may qualify for an above-guideline increase, separate those records from ordinary maintenance and get advice before promising a number to the tenant. A careful paper trail protects both cash flow and credibility.
For most owners, the safest rule is this: if you cannot clearly explain why the amount, date, and form are correct, pause before serving notice. That approach reduces disputes and protects long-term revenue far better than rushing a defective increase.
Frequently Asked Questions
How often can a landlord raise rent in Ontario?
In most cases, a landlord can raise rent only once every 12 months for the same tenant. The 12-month period runs from the date the tenancy began or from the last lawful rent increase. The landlord must also give proper written notice before the increase takes effect.
How much notice does a landlord need to give for a rent increase in Toronto?
For most private rental properties in Toronto, the landlord must give at least 90 days’ written notice using the proper Landlord and Tenant Board form. Toronto generally follows Ontario’s provincial rent rules, so the city does not create a separate standard notice period for most residential tenancies.
Are all Toronto rental units subject to the annual rent increase guideline?
No. Many Toronto rentals are covered by the annual guideline, but some units are exempt, especially certain units first occupied for residential purposes after November 15, 2018. Even when a unit is exempt from the guideline cap, landlords still generally need to follow the 12-month timing rule and proper notice requirements.
Can a landlord raise rent above the Ontario guideline because expenses went up?
Not automatically. A landlord usually needs Landlord and Tenant Board approval for an above-guideline increase, and only certain categories of costs may qualify. Rising general expenses alone do not let an owner simply impose a higher increase on a sitting tenant without following the legal application process.
Can a landlord increase rent when a lease becomes month to month?
A lease becoming month to month does not let a landlord raise rent immediately or outside the normal rules. The landlord still has to wait until at least 12 months have passed and must give the required written notice. Month-to-month status changes the tenancy term, not the rent increase rules.
