Protecting Yourself From Bad-Faith N12 Claims and T5 Applications

Bad faith is not about whether you were polite. It is about whether the stated reason for the eviction was the real reason. The two patterns the LTB sees most often are simple: the person who was supposed to move in never does, and the unit gets re-rented (often at a higher rent) shortly after the tenant leaves.

Ontario law builds in a rebuttable presumption of bad faith if you advertise, re-rent, demolish, or convert the unit within one year of the tenant leaving under an N12. If that happens, you are the one who has to explain it.

Evicting a tenant in order to re-rent at a higher price is not a permitted N12 reason and is treated as bad faith on its face. So is using personal use as a pretext to remove a tenant who complained or who you simply found difficult.

A T5 is filed by a former tenant, generally within one year of moving out. It alleges the N12 was served in bad faith. Once filed, the LTB looks past the paperwork and at the conduct.

The tribunal typically examines:

• Did the named person actually move in, and how soon after the tenant left?
• How long did that person stay, and is there independent proof of occupation?
• Was the unit advertised, listed, or re-rented within a year?
• If re-rented, was the new rent higher than the displaced tenant's?
• Is there a credible, documented reason the occupancy needed to happen then?
• Was the N12 preceded by a dispute, complaint, or tenant LTB filing?

The pattern matters more than any single fact. Genuine intent that is well documented survives a T5. A thin file does not, even when the landlord was actually acting honestly.

After a tenant vacates under an N12, the unit must genuinely be used for the stated purpose. If you re-rent it within one year, the law presumes the original N12 was in bad faith, and the burden flips to you to prove otherwise.

The practical advice is blunt: treat the one-year mark as a hard line in your calendar. If the occupant moves out before then, document why (a genuine change of circumstances, not a re-rental of convenience) and keep that record. Do not let a property manager or co-owner list the unit without checking the N12 date.

You can serve an N12 on behalf of a purchaser, but only where the buyer (or the buyer's close family member) genuinely intends to move in. The intent that matters is the buyer's, and the agreement of purchase and sale should record it. A sale that closes with the buyer never occupying is exactly the fact pattern that produces a T5 against the seller.

If you sell after serving an N12 for your own use, that sequence invites scrutiny. Be ready to show your own intent was genuine when you served, and that the sale decision came later for independent reasons. Keep the timeline and the reasons documented.

For the mechanics of the form itself, including the declaration requirements, see the N12 form Ontario guide.

Bill 60, passed in November 2025, introduced a longer 120-day notice option tied to compensation timing. Beyond the compensation mechanics, the longer notice has a defensive benefit that is easy to miss: it demonstrates planning.

A 120-day notice, served well before the end of the rental period, is consistent with a landlord who decided in advance, for genuine reasons, that they need the unit. A last-minute notice that coincides with a tenant dispute looks reactive. On a T5, the contrast between deliberate and reactive can be decisive. The longer route gives you a built-in piece of intent evidence: you committed early.
