The rules behind it
Three rules, and two exceptions.
As published by the Government of Ontario and the Landlord and Tenant Board.
The guideline
1.9% for 2027, 2.1% for 2026
For most rentals the rent can go up by at most the yearly guideline (2.5% in 2023 to 2025). Ontario publishes it by August 31 for the next year, and it is never more than 2.5%.

Notice
90 days, in writing
On the Landlord and Tenant Board’s form: N1 for most homes. Less notice and the increase isn’t valid; give a new notice with the full 90 days.

Exception
Homes first lived in after November 15, 2018
New buildings, additions and most new basement apartments aren’t covered by the guideline, so the increase can be more. The 12-month rule and 90 days’ notice still apply, on Form N2.

Exception
Above the guideline, with the Board’s approval
For a covered unit, only with an above-guideline increase from the Landlord and Tenant Board (after major repairs or a big jump in property taxes, for example) or by agreement in limited cases.

Questions
Rent increase questions.
Can I raise the rent when a new tenant moves in?
Yes. Between tenancies you can set the rent for the new tenant at any amount. The guideline then applies to increases during their tenancy.
Does the guideline apply to commercial units?
No. The guideline is part of the Residential Tenancies Act and covers residential rentals only.
Can you handle increases for me?
Yes. For homes we manage, we track every lease date, tell you when an increase is allowed and how much, and make sure the notice reaches the tenant on time on the Board’s form.
