Manitoba rent increase guidelines and the RTB process

Manitoba landlords navigating rent increases face a tightly regulated process governed by the Residential Tenancies Act (RTA) and overseen by the Residential Tenancies Branch (RTB). Unlike some provinces where rent control has been significantly rolled back, Manitoba maintains an annual guideline system that caps most increases and requires mandatory advance notice. Understanding exactly how the RTB framework works — and where landlords commonly go wrong — will save you time, money, and a formal hearing.

How Manitoba's Rent Regulation System Works

Manitoba's Residential Tenancies Act, C.C.S.M. c. R119, establishes that landlords generally cannot increase rent by more than the provincially set annual rent increase guideline without RTB approval. The guideline is calculated each year based on the Manitoba Consumer Price Index (CPI) and is announced by the province, typically in the fall for the following calendar year.

For 2024, the Manitoba rent increase guideline is 3%. For 2025, the guideline is set at 1.7%. These figures apply to most private residential tenancies in the province, including apartments, houses, and mobile home sites rented from site operators.

It is worth noting that some units are exempt from the guideline — including units first occupied for residential purposes after March 2, 2005, new mobile home sites, and certain subsidized housing arrangements. If your unit qualifies for an exemption, you can still only increase rent once every 12 months, but you are not bound to the guideline percentage. Confirm exemption status under Section 127 of the RTA before proceeding without guideline limits.

Required Notice: The 3-Month Rule

Under Section 119 of the RTA, a landlord must give a tenant written notice of a rent increase at least three full months before the increase takes effect. This is one of the most misunderstood requirements in Manitoba tenancy law.

"Three full months" means three complete calendar months — not 90 days, not 12 weeks. If a rent increase is meant to take effect on June 1, notice must be delivered no later than February 28 (or 29 in a leap year). Serving notice on March 1 means the earliest the increase can legally take effect is July 1.

The notice must be delivered in writing and must clearly state:

The current rent amount

The new rent amount

• The date the increase takes effect

There is no mandatory RTB-issued form for a standard guideline increase, but using clear written documentation — and keeping proof of delivery — is essential. Verbal notice is not valid under the RTA.

Above-Guideline Increases: Applying to the RTB

If your allowable costs genuinely exceed what the guideline covers, you can apply to the RTB for permission to increase rent above the guideline. This is a formal process and requires solid documentation.

Grounds for an Above-Guideline Application

Under Section 128 of the RTA, landlords may apply for an above-guideline increase based on:

Extraordinary operating cost increases — Utilities, property taxes, or insurance costs that have risen significantly above the guideline.

Capital expenditure costs — Major repairs or improvements to the property, such as a new roof, windows, or heating system, that benefit tenants and have a useful life extending beyond the current period.

1. Financing costs — Increases in mortgage costs that were not foreseeable at the time the tenancy was established (less commonly approved and subject to scrutiny).

Applications must be filed using RTB forms available on the Manitoba RTB website. You will need to submit financial statements, invoices, utility bills, tax assessments, or contractor agreements to support your claim. The RTB will schedule a hearing and notify affected tenants, who have the right to participate and challenge the application.

What the RTB Considers at a Hearing

The RTB adjudicator will assess whether the claimed costs are legitimate, unavoidable, and properly allocated to the residential portion of the property. If you own a mixed-use building, you must accurately apportion costs between residential and commercial units. Inflated or poorly documented claims are routinely rejected, and the RTB can approve a lower increase than requested. Decisions are issued in writing and can be appealed to the Court of King's Bench within 30 days under Section 162 of the RTA.

Frequency of Rent Increases

Regardless of whether your unit is subject to the guideline or exempt from it, Manitoba law allows only one rent increase per 12-month period per tenancy. This rule applies from the date of the last increase, not from a calendar year perspective.

For example, if you increased rent on April 1, 2024, the earliest you can increase it again is April 1, 2025 — and you must still serve the required three-month written notice before that date, meaning notice must go out no later than December 31, 2024.

New tenancies are also subject to this rule. The 12-month clock typically starts from the date the tenancy began or from the date of the last legal rent increase, whichever is more recent.

Common Mistakes Manitoba Landlords Make

Even experienced landlords trip up on the RTB process. Here are the most frequent errors that lead to invalid increases, RTB complaints, or reduced orders:

Counting 90 days instead of three full calendar months. A notice served on March 2 does not give three full months before June 1. The RTB is strict about this, and tenants can challenge improperly served notices.

Not putting the increase in writing. Telling a tenant verbally about a rent increase — or noting it in a text message without a formal written notice — does not meet the requirements of Section 119.

Attempting a second increase within 12 months. Some landlords mistakenly believe they can increase twice in one calendar year. The rule is 12 months from the last increase, not from January 1.

Assuming exempt units face no rules at all. Post-2005 units are exempt from the guideline percentage, but they still must follow the once-per-12-months rule and the three-month written notice requirement.

Filing an above-guideline application without documentation. The RTB expects financial evidence. Arriving at a hearing with vague cost estimates instead of actual invoices and financial statements almost always results in a reduced or denied order.

• Misidentifying the guideline year. Using a prior year's guideline percentage because you missed the announcement is not a valid defence. The province publishes guideline figures publicly; it is the landlord's responsibility to check before serving notice.

How Central Rentals Supports Manitoba Landlords

Keeping track of notice timelines, guideline percentages, and tenant-specific increase histories manually is where errors happen. A purpose-built property management platform can calculate the earliest valid effective date for any increase, flag upcoming notice deadlines, and store a full audit trail of notices served — all tied to individual tenancy records.

For above-guideline applications, having organized financial records in one place makes assembling the required documentation significantly faster. CRA-compliant income and expense tracking also matters here: if your above-guideline claim relies on demonstrating extraordinary operating cost increases, your records need to align with how those expenses appear on your T776 Statement of Real Estate Rentals. Discrepancies between what you claim at the RTB and what you've reported to CRA create real compliance risk.

Bottom Line

Manitoba's rent increase framework is structured, predictable, and enforceable — which is actually good news for landlords who follow it properly. Serve written notice three full calendar months in advance, stay within the annual guideline for covered units, limit increases to once every 12 months, and document everything. When costs genuinely require an above-guideline application, bring organized financial evidence to the RTB and expect the process to take time. Get these fundamentals right, and rent adjustments become a routine part of managing your portfolio rather than a source of disputes.
