Ontario rent increase rules: the mechanics, start to finish

01Who the guideline actually applies to

The rent increase guideline applies to most residential units covered by the Residential Tenancies Act where the unit was first occupied for residential purposes on or before November 15, 2018.

Units first occupied after that date are outside the percentage cap. So are community housing units, long-term care homes, and certain other categories. Being outside the cap does not put a unit outside the Act. The notice and timing rules still apply in full.

The guideline is a ceiling, not a target. You can increase by less, and many landlords do, because a good tenant who stays is worth more than the difference between 1.9% and nothing.

02The two timing rules

Two timing rules govern every increase, and they are independent of each other. Whichever is later is the one that controls.

First, at least 12 months must pass between increases for the same tenant, counting from the last increase or from the start of the tenancy if there has not been one. Second, the tenant must receive at least 90 days of written notice before the new rent takes effect.

Missing either invalidates the increase entirely. The tenant can keep paying the old rent, and you cannot quietly fix it later by sending a new notice with a shorter window. You start the 90 days again.

• 12 months since the last increase or the start of the tenancy
• 90 days of written notice on the correct form
• An amount within the guideline for the year the increase takes effect, unless the unit is exempt or an above-guideline increase has been approved
• Delivery you can prove, with the deemed service days counted

What can you actually raise the rent to?

Three rules decide every Ontario rent increase: the guideline for the year the increase takes effect, 90 days of written notice on Form N1, and 12 months since the last increase. Miss any one of them and the increase is void.

This unit was first occupied after November 15, 2018, so it is exempt from the guideline cap.

What the law allows

Put in the rent and the date of the last increase. You will get the maximum lawful rent, the earliest date it can take effect, and the day the notice has to be out the door.

General information about the Residential Tenancies Act, not legal advice. Confirm the guideline and the current N1 form with the Landlord and Tenant Board before you serve anything.

03N1 or N2, and why it matters

Form N1 is the notice of rent increase for a guideline increase. Form N2 is used where the unit is exempt from the guideline, which in practice usually means a unit first occupied after November 15, 2018.

Using the wrong form is a frequent reason tenants successfully push back, and it is entirely avoidable. Both forms want the same core information: the current rent, the new rent, the effective date, and the address. Keep a copy with the delivery date on it, the same way you would a lease amendment.

04When a tenant says the notice was invalid

05Above-guideline increases, briefly

An above-guideline increase is an application to the Board to exceed the guideline because of eligible capital expenditures, an extraordinary increase in municipal taxes and charges, or the cost of security services.

Most landlords with three to thirty units never file one, because the amount recoverable is capped at 3% above the guideline per year for a maximum of three years, and the documentation is substantial. That is a decision worth making with a calculator rather than a hunch.

06Make the window open by itself

Every increase should be tied to the lease and to the tenant, with the notice date, the effective date, the old rent and the new rent visible at a glance. When that lives in a personal inbox or a spreadsheet, the next increase cycle becomes an annual scramble and the mistakes above become likely rather than unlucky.

TenantBay carries the historical rent on each tenancy, so the eligible window is something the system knows about. The reminder arrives 90 days before it opens rather than the week a tenant asks. That turns a compliance task into a recurring step you confirm rather than a thing you have to remember.
