Ontario Rent Increase Rules Explained: 2026 Guideline, N1 Notices & AGI Applications

The 2026 Ontario rent increase guideline is 2.5%. Here's exactly how Hamilton and Niagara landlords can legally raise rent, when an Above Guideline Increase (AGI) makes sense, and how to file an N1 the right way.

What Is the Ontario Rent Increase Guideline?

Each year, the Ontario government publishes a **rent increase guideline** that caps how much landlords can raise rent on most existing tenancies. For **2026, the guideline is 2.5%** — applied once every 12 months with proper notice.

Which Units Are Covered?

The guideline applies to most rental units, **except** units first occupied after **November 15, 2018**, which are exempt from rent control (though all other RTA rules still apply).

How to Properly Increase Rent

1. **Wait 12 months** since the tenant moved in or since the last increase 2. Serve **Form N1 — Notice of Rent Increase** at least **90 days before** the new rent takes effect 3. Use the correct effective date — not earlier than the anniversary 4. Keep proof of service (registered mail, hand delivery with witness, or email if previously agreed)

Skip any of these steps and the increase is **void**, even if the tenant pays.

Above Guideline Increases (AGI)

If you've made significant capital improvements — new roof, windows, HVAC, elevator modernization — you may apply to the LTB for an **AGI** to recover those costs over time. AGIs are common in older Hamilton and St. Catharines buildings undergoing major upgrades.

Vacancy Decontrol

When a tenant moves out voluntarily, you can re-rent the unit at **any price** the market will bear. This is why turnover, while disruptive, can sometimes reset under-market rents in long-held Niagara properties.

Common Mistakes That Cost Landlords Thousands

  • Increasing rent without serving N1
  • Serving N1 less than 90 days in advance
  • Increasing more than once in 12 months
  • Forgetting to update lease addendums
  • Trying to "negotiate" a higher increase informally
