Manitoba Rent Increase Notice Form 1A: How to Fill It Out Correctly

Form 1A is the RTB's standard Notice of Rent Increase. The RTB also allows a landlord's own form if it contains all information required by the Act. A lease clause alone does not remove the statutory notice requirements.

What Form 1A Covers

Form 1A — officially "Notice of Rent Increase" — is prescribed under the Residential Rent Regulation (M.R. 156/92). Landlords generally use it for rent increases; the Act also permits their own form containing the information required by Sections 26 or 27. Non-profit life-lease units use Form 1B.

The form collects:

• Tenant's legal name and unit address
• Current lawful rent payable
• Proposed new rent (dollar amount and percentage change)
• Effective date of the increase
• Exemption status (guideline-covered or exempt, and why)
• Statutory text advising the tenant of their right to object to the RTB

Filling It Out: The Fields That Trip Landlords Up

Current rent: enter the lawful base rent before any conditional prompt-payment discount. If the tenant pays $1,200 after a $50 early-payment discount, the base rent is $1,250 — and the percentage increase applies to $1,250.

Percentage increase: for guideline-covered units, the increase cannot exceed 1.8% in 2026 or 3.0% in 2027, and Section 26 requires it to be shown in dollars and as a percentage. For units not subject to rent regulation, Section 27 requires the amount of the increase; it does not require a percentage.

Effective date: for a notice under Section 25(1), the increase must take effect at least three months after notice is given. Section 25(2) provides an exception for an increase at or within three months after a new tenant first occupies, if the landlord gives the notice required by Section 116.1. The Section 118 timing rule also applies, subject to its exceptions.

Exemption disclosure: Form 1A asks the landlord to state the reason if a unit is exempt from any part of the Act. Identify the applicable exemption when completing that field.

The 14-Day RTB Filing Rule

For notices covered by Section 28, the landlord must send a copy to the Residential Tenancies Branch within 14 days after giving it to the tenant. If the unit is vacant when notice is required, the copy is due within 14 days after the beginning of the three-month notice period. Section 28(2) lists exceptions.

The RTB's current Winnipeg office is at 1700-155 Carlton Street, Winnipeg, MB R3C 3H8. Form 1A is also available through the RTB's Electronic Forms Submission service.

Common Mistakes That Void the Notice

A notice with any of these defects may be invalid under Sections 25 to 27:

• Wrong current rent figure
• Missing statutory objection text
• Effective date that doesn't respect the three-month notice period
• Percentage increase that exceeds the guideline on a covered unit
• Impossible effective date (e.g., mid-month when rent is due monthly)

A deficient notice cannot authorize the proposed increase retroactively. The landlord must give a new compliant notice, and the three-month notice period runs from that notice.

Where to Get the Form

Form 1A is a free download from the RTB forms page. A landlord's own form is acceptable if it contains all information required by the Act for the unit.

The Manitoba Rent Increase Landlord's Guide includes a preparation worksheet that maps each Form 1A field to the information you need to gather before filling it in — plus a service log to document how and when you delivered it.
