Ontario Form N1: Notice of Rent Increase Guide for Tenants

Rent & Deposits Ontario published June 27, 2025 Flag of Ontario

If you’re renting in Ontario, you may someday receive a Form N1 – the official Notice of Rent Increase. This notice is regulated by provincial rules and gives landlords the legal authority to raise your rent. Understanding the process, your rights, and your options as a tenant will help you respond confidently to a rent increase.

Who Oversees Rent Increases in Ontario?

In Ontario, the main law governing rent increases is the Residential Tenancies Act, 2006[1]. All disputes or questions about rent increases are handled by the Landlord and Tenant Board (LTB).

What Is Form N1 – Notice of Rent Increase?

Form N1, or "Notice of Rent Increase", is the official notice landlords must give tenants in most residential tenancies to legally raise the rent. It tells you how much your rent will increase and when the new amount takes effect. The Form N1 is provided by the LTB and must be filled out correctly and served on tenants at least 90 days before the new rent starts.

When Is Form N1 Used?

  • When your unit is covered by rent control rules
  • Once per 12-month period (unless exempt)
  • With at least 90 days’ notice before the increase date

Example: Your landlord wants to increase rent from $1,200 to $1,236 (based on the annual guideline). They must give you a completed N1 at least 90 days before raising the rent.

Ontario’s Rent Increase Guidelines

Most rents in Ontario are subject to an annual guideline increase. This guideline is set by the Ontario government and published each year. Increases above this require special permission from the LTB.

Tip: If you’re unsure about the increase, check the year’s guideline and verify the math. Question any increases beyond the published percentage.

Exceptions: When N1 Does Not Apply

  • Rental units first occupied for residential purposes after Nov 15, 2018 (may be exempt from rent control)
  • Certain non-profit co-ops or government-funded housing
  • If there is a valid agreement with a different notice period or process

Your Rights and Next Steps After Receiving a Form N1

Tenants have rights protected by the Residential Tenancies Act, 2006. Landlords must:

  • Use the correct official Form N1
  • Respect annual guideline limits (unless approved by LTB)
  • Provide at least 90 days’ written notice

If you believe the notice is invalid or above the legal amount, you can contact the Landlord and Tenant Board to dispute it. You may also find advice in Obligations of Landlords and Tenants: Rights and Responsibilities Explained.

What Happens If You Don't Agree?

  • Remain in your unit: You do not need to move if you get a Form N1. Staying is your right.
  • Pay the existing rent until the 90-day period ends or a legal increase is allowed
  • Dispute the increase (if you believe it's invalid) by applying to the LTB
Remember: Talk to your landlord if you have questions, but always refer to the official LTB forms and procedures for disputes or appeals.

How to Respond to a Form N1 Step-by-Step

Here’s what to do if you receive a Notice of Rent Increase in Ontario:

  • Review the document (make sure it is the official N1 and is filled out correctly)
  • Check if your unit is covered by rent control and if the increase matches the annual guideline
  • Note the date and calculate if you have been given at least 90 days’ notice
  • If you have questions or concerns, contact the Landlord and Tenant Board or tenant help services
  • If you want to challenge the notice, file the appropriate application with the LTB as soon as possible

Summary: Tenants have protection from unfair rent increases—but you must understand your rights and act quickly if you want to challenge an N1 notice. Always keep a copy of any notice and your responses for your records.

Frequently Asked Questions (FAQ)

  1. Can my landlord raise the rent at any time using Form N1?
    No. Landlords must give a minimum of 90 days’ written notice and can typically only raise rent once every 12 months, following the provincial guideline.
  2. How much can my landlord increase my rent?
    Generally, rent can only be increased by the percentage set out in the provincial guideline for that year, unless the landlord receives approval for a higher amount from the LTB.
  3. What should I do if I get a rent increase above the guideline?
    Request your landlord's application for an above-guideline increase (Form N5 or N6), or contact the Landlord and Tenant Board to dispute the notice if it seems improper.
  4. Am I required to move if I can’t afford the new rent?
    No. Receiving a Form N1 does not force you to move. You may stay, but you’ll be required to pay the new rent once the notice period ends, unless you successfully dispute it.
