How do I log in to the LTB / Tribunals Ontario Portal?

Go to the Tribunals Ontario Portal from tribunalsontario.ca and sign in with a Public Secure account — Ontario's common login for government services. You can authenticate with a My Ontario login or a sign-in partner. If you don't have an account yet, create one and verify your email before starting an application.

Which LTB applications can be filed on the portal?

Landlords can file the L1, L2, L3, L4, L9 and L10 online, and tenants can file T1, T2, T5 and T6 (plus C1/C2 co-op applications). Filing online is also cheaper for the common applications — the L1, for example, is $186 online versus $201 by mail.

How do I link an existing LTB file to my portal account?

Log in, choose 'Link my Account to a File at LTB', enter your file number, and enter the one-time PIN the LTB issued for that file. Once linked, you can check the file's status, upload documents, and receive updates through the portal.

Why am I not receiving LTB portal emails?

Check your spam folder and your safe-sender list. Since July 24, 2026, all portal notifications come from ltbdonotreply@tribunalsontario.ca — replacing the old ltbdonotreply@ontario.ca address. If your filters were set up for the old address, hearing notices and orders can land in junk mail. Add the new address to your contacts.

I can't sign in — what should I check?

Work through the basics: confirm you're using the Public Secure credentials (not an old LTB e-file login), reset the password through the Public Secure page if needed, verify your email address is confirmed, and try a private browser window (cached sessions are a common culprit). If the account itself is locked, contact the LTB through the portal help page.

Do I have to use the portal, or can I still file by mail?

Mail and courier filing still exist (at a higher fee for most applications), and a few less-common forms aren't on the portal at all. But for the mainstream landlord applications — L1 through L4 — the portal is faster, cheaper, and gives you a live view of the file, so it's the default choice.

Tribunals Ontario Portal: Login & Account Guide for Landlords

Every mainstream LTB application — L1 through L4 — now files through the Tribunals Ontario Portal. This guide covers getting in: creating the Public Secure account, linking an existing file with your PIN, what can (and can't) be filed online, and the sign-in problems that actually trip people up.

Ready to file an L1? This page covers portal access. The step-by-step L1 filing walkthrough (respondents, exhibits, fees) lives in our how to file the L1 guide.

Step 1: Create (or Sign In With) a Public Secure Account

The portal doesn't have its own username and password — it authenticates through Public Secure, Ontario's common login for government services. From the Tribunals Ontario Portal page, choose sign-in and authenticate with a My Ontario login or a sign-in partner. First time: create the account, verify your email, and keep those credentials with your tenancy records — every future filing and hearing notice runs through them.

Step 2: Link an Existing LTB File

If you already have a case that started on paper (or someone filed on your behalf), link it: sign in, choose "Link my Account to a File at LTB", enter the file number, then enter the one-time PIN the LTB issued for the file. Once linked you can see the file status, upload documents, and receive portal notifications for it.

What Files Online (and What Doesn't)

Landlord applications: L1 (non-payment), L2 (other notices), L3 (tenant gave notice), L4 (broken settlement/order), L9, L10.
Tenant/co-op applications: T1, T2, T5, T6, C1, C2.
Cheaper online: the L1/L2 fee is $186 on the portal vs $201 by mail.
Still offline: some less-common applications and motions file by email or mail — the LTB's forms pages state the channel per form.

Whitelist the new notification address

Since July 24, 2026, every portal notification comes from ltbdonotreply@tribunalsontario.ca — not the old ltbdonotreply@ontario.ca. If your spam filter or contacts list still expects the old address, a hearing notice or an order can land in junk mail. Add the new address to your safe senders today; a missed hearing notice is not a defence.

Sign-In Troubleshooting

Old e-file credentials. Logins from the LTB's pre-portal e-file system don't work — the portal uses Public Secure only.
Unverified email. An account whose email was never confirmed can authenticate but stumbles on notifications — finish the verification step.
Cached sessions. If the sign-in loops, try a private/incognito window before anything else.
Wrong PIN on file linking. The PIN is per-file and single-use; if it's spent or lost, contact the LTB for a new one rather than guessing.
