A Canadian Rent Increase Notice is a formal written document that a landlord must deliver to a tenant before raising the rent on a residential tenancy. Every Canadian province requires written notice before a rent increase takes effect, though the specific notice periods, maximum allowable increases, and prescribed forms vary significantly across jurisdictions.

In Ontario, the Residential Tenancies Act, 2006 (S.O. 2006, c. 17) requires landlords to provide at least 90 days' written notice using prescribed Form N1 (s. 116). Rent may only be increased once every 12 months (s. 119), and for rent-controlled units, the annual increase is capped at the provincial guideline rate published each year by the Ministry of Housing (s. 120). The 2026 Ontario guideline is 2.1%. Units first occupied for residential purposes after November 15, 2018 are generally exempt from the guideline cap under section 6.1. Landlords seeking to exceed the guideline for eligible reasons (capital expenditures, extraordinary operating costs) must obtain an order from the Landlord and Tenant Board under sections 126-127.

In British Columbia, the Residential Tenancy Act (S.B.C. 2002, c. 78) requires at least three full months' written notice on prescribed Form RTB-7 (s. 42). Rent increases are capped at the annual maximum allowable increase set by the Residential Tenancy Branch, which is 2.3% for 2026. Increases may only occur once every 12 months.

In Alberta, the Residential Tenancies Act (R.S.A. 2000, c. R-17) does not impose a cap on rent increases, but landlords must give at least three tenancy months' notice for monthly periodic tenancies, and no increase may take effect less than 365 days after the last increase or the start of the tenancy (s. 37). Similar no-cap rules apply in Saskatchewan and New Brunswick, while Manitoba and Prince Edward Island maintain rent increase guidelines.

A rent increase that does not comply with provincial notice requirements or exceeds the applicable guideline is void and unenforceable. The tenant is not obligated to pay a void increase and may file a complaint with the applicable provincial tribunal.

When a landlord wishes to increase the rent on a residential tenancy at the end of a lease term or during a periodic tenancy, and must provide the tenant with formal written notice complying with provincial minimum notice periods and guideline caps.

When a lease renewal involves a rent increase and the landlord needs a standalone notice document to satisfy the prescribed notice requirements, separate from the renewal agreement itself.

When a landlord has received approval from a provincial tenancy tribunal for an above-guideline rent increase and must serve formal notice on affected tenants detailing the tribunal order number, approved percentage, and effective date.

When a rental unit is exempt from provincial rent control (such as Ontario post-November 2018 units) and the landlord needs to document a rent increase that exceeds the guideline rate while still providing the required notice period.

When the last month's rent deposit in Ontario needs to be adjusted in connection with a lawful rent increase, and the landlord must document the adjustment, interest calculation, and any additional amount owed by the tenant.

When a landlord needs a documented record of having provided proper notice in case a tenant disputes the increase before the Landlord and Tenant Board, Residential Tenancy Branch, or Residential Tenancy Dispute Resolution Service.

Current and New Rent Amounts — The notice must clearly state the current monthly rent, the new monthly rent, the dollar increase, and the percentage increase. This transparency is required by provincial legislation and helps the tenant verify compliance with guideline caps.

Effective Date — The date the new rent takes effect, which must allow for the minimum notice period. Ontario requires 90 days (RTA s. 116), BC requires three full months (RTA s. 42), and Alberta requires three tenancy months with a 365-day interval between increases (RTA s. 37).

Rent Control Compliance — A statement indicating whether the unit is subject to rent control, exempt, or covered by an above-guideline tribunal order. This is critical in Ontario where the distinction between pre-2018 and post-2018 units determines whether the guideline applies.

Above-Guideline Tribunal Order — If the increase exceeds the provincial guideline, the notice must reference the tribunal file number, order date, and approved percentage. Without a valid tribunal order, the above-guideline portion is void.

Notice Period Compliance — The notice must demonstrate that the required notice period has been met by stating the notice date, delivery method, and effective date. Insufficient notice renders the entire increase void.

12-Month Rule — The notice should state the date of the last rent increase (or tenancy start date) to confirm that at least 12 months have elapsed, as required in all provinces.

Deposit Adjustment (Ontario) — If applicable, the notice should document the adjustment to the last month's rent deposit, including interest owed by the landlord and any additional payment required from the tenant.

Payment Instructions — Updated payment details including the payment method and payee for the new rent amount.

Tenant Rights Statement — Information about the tenant's right to dispute an unlawful increase before the applicable provincial tribunal, including filing deadlines.

Delivery Method — The method by which the notice was served, which must comply with provincial rules for valid service of notice.
