Legal Precedents & Case Summaries New Brunswick published: June 19, 2025

Facing a rent increase can be stressful for tenants in New Brunswick, especially when you're unsure of your rights. Court decisions and legal precedents help shape how rent increases are handled under New Brunswick law. Understanding how the law is applied—and the rights and remedies available—can empower tenants to make informed decisions and respond confidently.

Understanding Rent Increase Laws in New Brunswick

In New Brunswick, rent increases are governed by the Residential Tenancies Act. Unlike some provinces, there is no fixed guideline or cap on rent increases, but there are strict notice and procedural requirements that landlords must follow.

Notice requirement: Landlords must give written notice of a rent increase at least three months before it takes effect for both month-to-month and year-to-year leases.
Form and delivery: The notice must be in writing, stating both the new rental amount and the date it comes into effect.
Challenge rights: Tenants have the right to dispute a proposed rent increase if they believe it is unreasonable or not in accordance with the law.

Top Court and Tribunal Decisions on Rent Increases

Most rent-related disputes are handled by the Residential Tenancies Tribunal of New Brunswick, which interprets and enforces the Residential Tenancies Act¹. Key decisions from this Tribunal and higher courts help clarify how and when a rent increase may be considered void or unenforceable.

Key Precedent: Reasonability and Notice Under Review

Several Tribunal decisions have emphasized that proper notice—and proof of delivery—is essential. If a landlord fails to provide at least three full months’ notice or uses an improper delivery method, the increase can be ruled invalid.

In Poirier v. Smith (2022 Tribunal), the Tribunal ruled a rent increase void where the landlord failed to provide the written notice in time. This meant the tenant’s rent could not increase until proper notice was given.
Court decisions have also upheld that a significant or sudden rent increase (without justification) can be challenged if there are concerns about fairness or retaliatory motive.

These decisions empower tenants to challenge unlawful or excessively large rent increases, reinforcing your right to safe and stable housing.

How to Challenge a Rent Increase: Official Forms and Process

If you believe a rent increase is unfair or improperly served, you can apply to the Tribunal for a review. The main form you will need is the Application to Review Rent Increase (Form 12).

Form Name: Application to Review Rent Increase (Form 12)
When to use: When you’ve received a rent increase notice and want to challenge it before it takes effect.
Where to find: Official Application for Review of Rent Increase (Form 12)
Practical example: If your landlord notifies you in March that rent will increase in June, but the notice was not delivered with the three-month minimum or you believe the increase is too high, use Form 12 to apply for the Tribunal to review and possibly block the increase.

Action Steps for Tenants:

Carefully review rent increase notices for correct dates and information.
File Form 12 within 30 days of receiving the rent increase notice.
Keep a copy of all correspondence for your records.
Attend your hearing or participate as instructed by the Tribunal.
