Rent & Deposits New Brunswick published June 13, 2025 Flag of New Brunswick

If you're a tenant in New Brunswick and your landlord raises your rent without notice, it's natural to feel concerned or confused. Understanding your rights and the steps you can take under New Brunswick’s rental laws can help you respond confidently and protect yourself from unfair treatment. This guide breaks down what to do, official forms to use, and where to get help.

Your Rights Regarding Rent Increases in New Brunswick

New Brunswick’s Residential Tenancies Act sets out specific rules that limit how and when landlords can increase rent.

  • Written Notice Required: Landlords must provide tenants with written notice of a rent increase.
  • Notice Period: The required notice period is at least three months before the rent increase takes effect.
  • This applies to monthly, yearly, and week-to-week leases.

The landlord cannot increase your rent until the correct notice period has passed. If your rent is raised without notice, the increase is not valid and you are within your rights to challenge it.

What To Do If Your Rent Is Increased Without Proper Notice

If you receive a rent increase without the required three months' written notice, here are your practical steps:

  • Do not pay the increased amount unless the proper notice has been given.
  • Request confirmation from your landlord about the date and method of notice.
  • If you did not receive written notice, inform your landlord, referencing your rights under the Residential Tenancies Act (New Brunswick).
  • Keep detailed notes and copies of all correspondence.

If the landlord insists on the increase or threatens eviction, you should formally dispute the rent increase. New Brunswick has specific government processes to protect tenants in these situations.
