Ontario's residential tenancy rules changed significantly on September 21, 2026, and anyone who owns, rents, buys or sells a tenanted property should understand the new timelines before taking action.

The changes affect three particularly important areas: non-payment of rent (N4), landlord's-own-use evictions (N12), and renovations/repairs requiring vacant possession (N13). They arise from amendments to Ontario's Residential Tenancies Act, 2006, associated with Bill 60 and Bill 97. The Landlord and Tenant Board (LTB) also updated forms, procedures and guidance.

These changes matter beyond traditional landlord-tenant disputes. They can directly affect Ontario real estate transactions involving tenanted houses, condos and investment properties, particularly where a buyer expects vacant possession.

What Changed in Ontario on September 21, 2026?

The changes took effect on September 21, 2026, and are in addition to LTB changes introduced earlier on July 1, 2026. The LTB says they result from amendments to the Residential Tenancies Act, 2006 introduced through the Fighting Delays, Building Faster Act (Bill 60) and the Helping Homebuyers, Protecting Tenants Act, 2023 (Bill 97). For most homeowners, investors and renters, three areas deserve immediate attention.

1. N4 Non-Payment of Rent: The Notice Period Is Now 7 Days

Does this mean a tenant is evicted after seven days? No. This distinction is extremely important. An N4 notice is part of the legal process; it is not itself an eviction order. The shorter notice period means the process can move to the next stage sooner, but landlords still have to follow the applicable LTB process. The LTB also confirms that rent is considered late when it has not been paid in full by the date it is due.

Persistent Late Payment Now Has a Clearer Definition

As of September 21, a tenant is considered to have persistently paid rent late where rent is received more than seven days after its due date at least three times during a six-month period. The LTB notes that persistent late payment may also be found in other circumstances.

Another Major Change: The 50% Arrears Requirement

Where a landlord's rent-arrears application was filed on or after September 21, a tenant who wants to raise other issues at the hearing — such as maintenance or tenant-rights concerns — must pay the landlord half of the rent arrears claimed in the application at least seven days before the hearing. The existing notice/evidence requirements also continue to apply, and the payment is made directly to the landlord rather than to the Board in trust.

Why landlords should care: the shorter timeline does not mean rushing through the process — quite the opposite. When statutory timelines become tighter, accuracy becomes even more important. Incorrect dates, calculations or forms can create problems.

Why tenants should care: an N4 should not be ignored. The move from 14 days to seven days means there is considerably less time to understand the notice and determine the appropriate response.

2. N12 Landlord's Own Use: 60 Days vs. 120 Days Now Matters

The second major change concerns an N12 Notice to End Tenancy Because the Landlord, a Purchaser or a Family Member Requires the Rental Unit. The September amendments create an important distinction for landlord's-own-use situations.

But there is a major limitation: the new 120-day exception does NOT apply to N12 notices for a purchaser's own use. That distinction is extremely important for REALTORS®, sellers, buyers and investors.

Selling a Tenanted Property? Don't Assume the Sale Ends the Tenancy

A common real estate misunderstanding is: "I'm selling the property, so the tenant has to leave." A sale itself should not be treated as automatically terminating the tenancy. And the new 120-day landlord-own-use exception should not be confused with purchaser-own-use situations — that matters when drafting agreements and discussing vacant possession.

Before a seller promises vacant possession — or a buyer assumes they will receive it — the tenancy situation needs to be properly understood. This is particularly important with:

Real estate professionals can help clients understand the transaction and coordinate the process, but legal questions concerning tenancy termination should be referred to an appropriate legal professional.

3. N12 Good Faith: The Intended Occupant Actually Has to Move In

The law also reinforces the importance of genuine landlord's-own-use claims. Effective September 21, the landlord or other qualifying person identified for a landlord's-own-use N12 must normally take occupancy within 60 days of the date specified in the N12 notice.

If that does not occur, and the former tenant files a T5 bad-faith application, the N12 is presumed to have been given in bad faith, although the landlord has an opportunity to rebut that presumption at the hearing. Again, this rule does not apply to N12 notices served for a purchaser's use of the property. The practical message is clear: an N12 is not simply a mechanism for obtaining a vacant rental property — the intended residential occupation has to be genuine.

4. Renovictions and N13: Stronger Procedures Around the Right to Return

The September changes add further landlord obligations. Where the tenant has properly indicated an intention to return, the landlord must provide written information about the estimated completion date, provide updates if that estimate changes, and notify the tenant when the work is completed and the unit is ready for occupancy.

5. Tenant Remedies for Renovation Cases Have Changed Too

For applicable right-of-first-refusal disputes, the deadline for a tenant to file a T5 Application is now two years after the tenant moves out or six months after the renovations are finished, whichever is later. The LTB also says that where the tenant properly gave written notice that they wanted to return, but the landlord failed to provide the required information or failed to give the tenant 60 days to move back in, there can be a rebuttable presumption that the landlord failed to provide the right of first refusal. That makes documentation particularly important for both sides.

What Do These Changes Mean for Ontario Landlords?

The amendments give landlords faster procedures in some circumstances, but they don't eliminate the need to comply with the RTA. Three practical lessons stand out:

1. Use current forms. The LTB updated several forms on September 21, including N12, N13, L1, L2, L9, L10 and T5, while an updated N4 is also available. The LTB says previous versions of the affected updated forms will no longer be accepted as of November 30, 2026.
2. Document everything. Dates, notices, rent payments, communications and renovation notifications can become important evidence.
3. Distinguish landlord's own use from purchaser's own use. The new 120-day N12 compensation exception is specifically limited to landlord-own-use situations.

What Do These Changes Mean for Ontario Tenants?

The most immediate change is speed. A tenant receiving an N4 now has a substantially shorter notice period than before, which means notices should be reviewed promptly rather than left until later. For renovation situations, tenants who want to preserve a potential right to return should pay particular attention to the written-notice and address-update requirements. And where there is a dispute, tenants should understand that the September changes also affect what may be required before raising certain issues at a rent-arrears hearing.

What Do the New Rules Mean for Ontario Home Buyers?

This is where tenancy law and real estate transactions intersect. Suppose you're purchasing a house containing a tenant and your intention is to move into the property — you should not simply assume "I'm buying it, therefore the tenant will be gone by closing." The status of the tenancy, the agreement of purchase and sale, notice requirements, closing date and purchaser's intended use can all become relevant. Importantly, the new 120-day compensation exception for landlord's-own-use N12 notices does not apply to purchaser-own-use N12s. This makes proper planning before submitting an offer especially important.

The Bottom Line: 7 Days. 120 Days. 60 Days.

Ontario's September 21, 2026 tenancy changes are significant because they affect both timelines and responsibilities. 7 days: the new N4 non-payment notice period. 120 days: an important threshold for the new landlord-own-use N12 compensation exception. 60 days: relevant to landlord-own-use occupancy requirements and the opportunity to return following qualifying renovations.

For landlords, the changes make accurate notices, documentation and timing particularly important. For tenants, some deadlines now move faster, while the renovation rules provide clearer procedures surrounding the right to return. For buyers and sellers, the biggest lesson is simple:

A tenanted property is not the same as a vacant property. Understand the tenancy before making promises about possession or closing.
