Ontario's rental rules change on Monday. Here's what's different.

Fourteen days just became seven. Ready or not, Barrie.

On Monday, September 21, 2026, the biggest set of changes to Ontario's rental rules in years takes effect. If you rent in Barrie, Innisfil, Orillia, Bradford, Wasaga, or anywhere in Simcoe County, or if you own a rental here, the rules you're used to are about to change. Some of them change a lot.

This isn't a Toronto story. Most rentals around here aren't big towers with property management companies. They're basement apartments, the other half of a semi, or a house owned by someone who moved for work. That means most landlords and tenants in our area deal with each other directly, often without professional help. So it matters that everyone knows the new rules, ideally before Monday.

Here's what's changing, in plain English.

1. The N4 deadline drops from 14 days to 7

The N4 is the notice a landlord gives when rent hasn't been paid. Until now, most monthly tenants had 14 days before the landlord could apply to the Landlord and Tenant Board (LTB). For any N4 served on or after September 21, that becomes 7 days.

An N4 served before Monday still follows the old 14-day rule.

For perspective, the LTB currently schedules non-payment hearings about three months out on average. Seven days is how soon your landlord can file, not how soon anything happens to you. But don't take that as permission to wait. Every week you let slip is another week of arrears added to the claim.

2. “Persistently late” now has a number

Landlords have always been able to use an N8 to end a tenancy for persistent late payment. But nobody could say exactly what “persistent” meant. Now there's a number attached to it: rent paid more than 7 days late, 3 times, within any 6-month period.

Read that as a floor, not a ceiling. Hit it and the Board must find persistent lateness — but it can still find it without it. Two badly late payments and a history of excuses is an argument a landlord can still make.

For tenants, this means being a week late every so often is now something a landlord can count. If your pay schedule doesn't line up with your rent date, ask your landlord in writing to change the due date. Many will agree. Setting up automatic payments is the easiest protection.

An N8 isn't a surprise eviction either. It ends the tenancy at the end of the rental period or lease term, and the landlord still needs an LTB order.

For landlords, the test only helps if you can prove it. Keep a simple log of the date each payment actually arrives. A spreadsheet is fine, as long as you fill it in at the time rather than rebuilding it from memory later. If you are already past that point, the full arrears timeline is here.

3. Want to raise repair issues at a rent hearing? Pay half first

Right now, at a hearing about unpaid rent, a tenant can raise their own complaints, such as repairs that were never done or a landlord entering without notice, and ask the Board to take them into account.

For applications filed on or after September 21, a tenant who wants to raise those issues at the hearing must pay half of the arrears claimed at least 7 days before the hearing.

4. Landlords moving in: a new 120-day option, and a stricter move-in rule

This one matters a lot in our area, because so many Simcoe County rentals are owned by individuals who may one day want the unit back for themselves, a parent, or a grown child.

Until now, an N12 (landlord's own use) required 60 days' notice plus one month's rent as compensation. That option still exists. There's now a second option: an individual landlord can give at least 120 days' notice and not pay the one month's compensation.

The 120-day option is narrow. It's for individual landlords who are moving in themselves or moving in family. It doesn't apply to notices given on behalf of a buyer, or to corporations.

The other side is tougher too. The person named in the notice must actually move in within 60 days of the tenant leaving. If nobody does, bad faith is presumed. That word is the whole change: the landlord now has to prove they meant it, instead of the former tenant having to prove they didn't. A bad-faith finding means compensation to the tenant, and can mean a fine on top.

Tenants: if you get an N12, check which option your landlord used, whether the notice period is correct, and whether compensation is owed. Then keep an eye on the unit after you move out.

5. Renovictions: landlords must keep tenants informed

If a landlord ends a tenancy for major renovations or demolition (an N13, which generally requires at least 120 days' notice) and the tenant has said in writing that they want to move back in, the landlord must now keep that tenant updated in writing. That means giving the expected completion date, telling the tenant if that date changes, and notifying them when the unit is actually ready. The tenant keeps the right to return at the same rent. If the landlord doesn't follow through, the tenant can seek compensation through the LTB.

Already in effect since July 1

A few changes took effect quietly this summer, and people are already getting caught by them:

• You now have 15 days, not 30, to request a review of an LTB decision. If a decision goes against you, you have half the time you used to.
• Tenants have clearer rights to air conditioning. You can install a window or portable unit — but you have to give your landlord written notice first, and the installation has to be safe and not damage the unit. Where electricity is included in your rent, your landlord is allowed to charge a seasonal increase for running it — capped at what the electricity actually costs.
• Repayment plans made under section 206 must use the LTB's official Payment Agreement form.
• Above-guideline rent increases move faster. A landlord now has 7 days, not 14, to serve an AGI order once it's issued, and 5 days after that to file the certificate of service.
• Maximum fines under the Residential Tenancies Act have doubled — $100,000 for an individual, $500,000 for a corporation.

What hasn't changed

A landlord still can't evict you without a valid reason and an LTB order. The 2.1% rent increase guideline for 2026 still applies to rent-controlled units. Units first occupied after November 15, 2018 are still exempt from rent control. Landlords still need to give 24 hours' written notice before entering, and they still have to keep the unit in good repair.

Also be aware that most of what you'll find online about Ontario rental law was written before these changes. If a website tells you that you have 14 days on an N4, it's out of date.

What we recommend this week

If you're a tenant:

1. If you're behind on rent, try to catch up before Monday, or get a repayment plan in writing now.
2. Set up automatic rent payments, or ask your landlord in writing to move the due date to match your payday.
3. If you have repair problems, start documenting them now with photos, dates, texts, and emails. Consider filing a T6 before any rent dispute comes up.
4. If you receive any notice, photograph it and call us at (705) 252-5213 before you sign anything.

If you're a landlord:

1. Delete any N4 template saved on your computer. Download the current form from Tribunals Ontario every time you serve one.
2. Start a payment log for each unit today.
3. If you're thinking about an N12, talk to us before you serve it. Choosing between the 60-day and 120-day paths is a real decision, and the 60-day move-in rule has teeth.
4. If you have a renovation underway, keep a written record of every update you send your tenant.

If you want to see how the whole process fits together, our LTB walkthrough lays out every form and step in order.

This is general information, not legal advice. Every tenancy is different, and these rules are brand new, so how the LTB interprets them will develop over the coming months. Call us and we'll tell you what your situation specifically requires.
