There is a new LTB forms Ontario deadline on the calendar: November 30, 2026.
You serve a notice, wait out the notice period, file your application, and the Board sends it back because the form was last year’s version. That is weeks lost on a file where every week costs you rent.
This is about to happen to a lot of landlords. The new LTB forms in Ontario have been live since September 21, 2026. The Board has said previous versions will no longer be accepted as of November 30, 2026. Today is November 4. You have 26 days.
New LTB forms Ontario: what changed on September 21
The Landlord and Tenant Board replaced ten forms on the Tribunals Ontario portal and updated the N4. The replaced forms are the N5, N6, N8, N12, N13, L1, L2, L9, L10 and T5. The Board lists the changes in its September 21 operational update.
The forms changed because the rules behind them changed. The N4 termination period for unpaid rent dropped from 14 days to 7 for notices given on or after September 21. A tenant who wants to raise other issues at an arrears hearing now has to pay half the claimed arrears to the landlord at least 7 days before the hearing. The N12 has new rules on compensation and on when the landlord must move in. The N13 has new reporting duties.
If you are filling in an old form, you are working from rules that no longer apply.
Where old forms hide
Most landlords do not use the wrong form on purpose. They use the one that was already saved.
We took over a fourplex in Ward 3 last year where the previous owner kept a binder of pre-filled notices in the basement utility room. Every form was a version behind. The owner was not careless. He had used that binder for eight years and it had always worked.
Old forms hide in four places:
- A “Landlord forms” folder on a desktop or shared drive
- Printed stacks in a truck, office or binder
- Property management software with built-in templates
- Old emails you reuse as a starting point
A cleanup you can finish this week
Work through this new LTB forms Ontario cleanup before November 30:
- Delete every saved copy of the ten replaced forms and the old N4. Do not archive them in the same folder.
- Download fresh copies from the Tribunals Ontario website and save them in one folder with the date.
- Check your property management software or accounting tool. If it generates notices, confirm it uses the new versions. If it does not, stop using it for LTB forms until the vendor updates.
- Throw out printed stacks. Print new copies when you need them.
- Tell anyone who serves notices for you. That includes a superintendent, a family member helping with a rental, or a bookkeeper.
Transition rules that catch people
Replacing the form is the easy part. The harder question is which rules apply to a file you started before September 21.
The dates that matter differ by form. For the N4 and N12, the rule depends on the date you served the notice. For the half-arrears requirement, it depends on the date you filed the application. For the N13, it depends on when the tenant gave you written notice that they plan to move back in.
Take a tenant who got an N4 on September 15. That notice follows the old 14-day rule. A tenant served on September 22 gets 7 days. Same building, same landlord, different rules.
The N12 shows the same split. If you are planning a personal-use eviction, the 120-day notice option can remove the one-month compensation requirement for notices served on or after September 21. It does not apply to purchaser’s own use. Our N12 and Bill 60 explainer walks through the details. If you are wondering how these changes affect your wait for a hearing, see our post on LTB hearing timelines after Bill 60.
If you have a file in progress and you are not sure which rules apply, stop and check before you file. A wrong form is a fixable mistake. A notice served under the wrong rules can mean starting over.
How we handle this at Found Spaces
I started this company from nothing, and we now manage more than 600 rental units in Hamilton and the surrounding area. When the Board changes forms, we change our templates the same week. One person owns the form library. Nobody on the team pulls a notice from an old email or a desktop folder.
That is not a clever system. It is a boring one. On 600 units, boring is what keeps files from being rejected. If you are a self-managing owner with three or four units, you can run the same system in an afternoon.
That same system is how we stay ahead of every new LTB forms Ontario update.
Where a file is heading to a hearing, our landlord legal services team prepares the paperwork and represents owners at the Board.
Before November 30
Spend an hour this week on the cleanup above. Check any notice you plan to serve in the next month against the new rules. If a notice or application is already in progress and you are not sure it is correct, ask someone to look at it before the Board does.
If you would rather hand all of this off, we are happy to talk through your portfolio. You can see how our rental property management in Hamilton works, or email us at [email protected].
