How to Raise Rent on an Existing Tenant in Ontario Without Losing Them

By Solutions Property Management — Sat May 09 2026

Wondering how to raise rent in Ontario without losing a good tenant? This guide covers the legal process, the right amount, timing, and how to have the conversation.

The Legal Requirements First

Before anything else, understand the rules:

• You can only raise rent once every 12 months per unit.
• You must give at least 90 days written notice before the increase takes effect.
• The notice must be issued on the official N1 form from the LTB.
• For most units occupied before November 15, 2018, the increase is capped at the annual guideline — 2.1% in 2026.
• Units first occupied after November 15, 2018 are not subject to the guideline cap, but the 90-day notice and 12-month frequency rules still apply.

Verbal notice, email, or a letter in the wrong format are not valid. Use the N1 form.

How Much Should You Raise the Rent?

For guideline-controlled units, the maximum is 2.1% in 2026. But just because you can

does not always mean you should raise it by the full amount if a quiet, reliable tenant

occupies a well-maintained unit.

For units not subject to rent control, or when re-setting rent at turnover, you should base

the new rent on a proper market analysis. Look at:

• Comparable units currently listed in the same neighbourhood
• How long those units are sitting on the market at that price
• The condition and upgrades of your unit relative to the competition

A professional property manager does this analysis as part of their annual review, rather than guessing or simply applying the guideline automatically.

How to Have the Conversation

Good tenants who receive a rent increase notice without any prior communication are more likely to start looking for alternatives. Here is a better approach:

5. Give context before the formal notice. A simple message explaining that costs have increased and rents in the area have moved up — and that you wanted to give them advance notice — can go a long way.

6. Send the N1 form on time. Even if you have had the verbal conversation, the legal 90-day notice period only starts from when the written N1 is served.

7. Be transparent about the amount. Tenants who feel blindsided are more likely to leave. Tenants who feel respected are more likely to accept a reasonable increase.

When You Should Not Raise Rent

There are situations where skipping the increase is the smarter financial move:

• The tenant is exceptional — pays on time, keeps the unit immaculate, renews reliably — and a vacancy would cost you more than a year of the increase would earn.
• The unit has deferred maintenance and you have not followed through. Raising rent before addressing legitimate concerns damages the relationship and creates LTB exposure.
• The market has softened and a vacancy would mean listing at the same or lower rent anyway.

Frequently Asked Questions

Q: What form do I use to raise rent in Ontario?

A: The N1 form — Notice of Rent Increase — is the official form used to notify tenants of a rent increase in Ontario. It is available for free on the Landlord and Tenant Board website at tribunalsontario.ca.

Q: Can I raise rent by more than the guideline if I did renovations?

A: You can apply to the LTB for an above-guideline increase if you have completed significant capital repairs or improvements to the property. This requires a formal application with documentation. Routine maintenance does not qualify.

Q: What happens if I raise rent without giving 90 days notice?

A: The rent increase is not legally valid. The tenant can refuse to pay the increase and the LTB would uphold their position. You would need to serve a correct N1 and wait the full 90 days before the new amount takes effect.

Q: Can a tenant refuse a rent increase in Ontario?

A: A tenant cannot refuse a legally issued rent increase that follows the proper process and stays within the guideline. However, a tenant can file a T1 application with the LTB

if they believe the increase was issued improperly or exceeds the guideline for a controlled unit.

**Q: What is the most I can raise rent in Ontario in 2026?** A: For units occupied before November 15, 2018, the maximum is 2.1%, the 2026 rent increase guideline. For units first occupied after November 15, 2018, there is no cap — you can raise to market rate, but you must still give 90 days written notice and can only do it once per 12 months.

The Bottom Line

Raising rent in Ontario is a legal process with specific forms, timelines, and limits. Done correctly, it maintains your income in line with rising costs without damaging your tenant relationship. Done poorly, it can trigger vacancies that cost you far more than the increase would have earned.
