Ontario Residential Tenancies Act: What Every Niagara Landlord Needs to Know in 2026

 Yes — the Ontario Residential Tenancies Act applies to virtually all residential rental properties in Ontario, including all properties across the Niagara Region. This includes detached houses, semi-detached homes, townhouses, condominiums, basement apartments, and secondary suites. Very limited exemptions exist — for example, shared kitchen/bathroom situations in the landlord’s own primary residence — but the vast majority of Niagara rental situations are fully governed by the RTA. There is no municipal variation in RTA rules across the Niagara Region; the provincial law applies uniformly.

The Ontario rent increase guideline for 2026 is 2.1%. This is the maximum annual rent increase that landlords of rent-controlled units can apply without seeking LTB approval for an above-guideline increase. Rent-controlled units are those first occupied for residential purposes before November 15, 2018. Landlords of newer units (first occupied on or after November 15, 2018) are not subject to the rent increase guideline and can set any rent increase, provided they give 90 days’ written notice using Form N1.

 Bill 60 — the Fighting Delays, Building Faster Act, 2025 — introduces two key changes to eviction notice rules. First, the voiding period for an N4 Notice (non-payment of rent) is being shortened from 14 days to 7 days, effective September 21, 2026. This means tenants will have less time to pay overdue rent before a formal LTB eviction application can be filed. Second, the requirement for landlords to pay one month’s compensation when serving an N12 (own-use) eviction notice is being removed — provided the N12 specifies a termination date at least 120 days from the date of the notice. This takes effect September 21, 2026. Landlords should note that these changes apply to applications made after the in-force dates.

 No — refusing to rent to an applicant because their income comes from ODSP, Ontario Works, or other government income assistance is a violation of the Ontario Human Rights Code. Source of income is a protected ground in Ontario housing. What you can do is apply a consistent, documented income threshold to all applicants — requiring, for example, that verifiable household income is 2.5–3x monthly rent. As long as this criterion is applied equally to all applicants, it is a permissible screening criterion. Refusing specifically because of ODSP or OW status — regardless of the overall income amount — is not permissible.

 To legally increase rent in 2026, you must: (1) ensure at least 12 months have passed since the last rent increase or since the tenancy began; (2) give the tenant at least 90 days written notice using Form N1 before the new rent takes effect; and (3) ensure the increase does not exceed 2.1% for rent-controlled units, unless you have LTB approval for an above-guideline increase. You cannot increase rent mid-lease unless the lease has a specific rent escalation clause that is RTA-compliant. Verbal rent increases are not enforceable.

 If your tenant does not pay rent when due, the legal process is: (1) serve the tenant an N4 Notice to End a Tenancy Early for Non-payment of Rent — giving them the voiding period to pay all arrears; (2) if they do not pay within the voiding period, file an L1 Application with the LTB; (3) attend the LTB hearing; (4) if an eviction order is issued and not followed, request enforcement through the Court Enforcement Office (Sheriff). Never change locks, remove belongings, or cut off utilities — these are illegal self-help eviction measures under the RTA and can result in significant penalties for the landlord. From September 21, 2026, the N4 voiding period shortens from 14 to 7 days under Bill 60.

 From July 1, 2026, when a landlord has filed an L1 application with the LTB for rent arrears, and both parties reach a written agreement resolving those arrears, the LTB can issue a payment order without holding a hearing — provided the agreement is documented on an LTB-approved form (a new requirement under Bill 97). This allows faster resolution of arrears disputes without waiting for a full LTB hearing. If the tenant later breaches the payment agreement, the landlord can apply to reopen the original application without serving a new eviction notice, as long as the reopening request is filed within 30 days of the tenant’s first breach.

 Landlords can enter a rental unit without notice only in two circumstances: a genuine emergency (fire, flood, burst pipe, or other urgent situation requiring immediate entry) or where the tenant provides consent at the exact time of entry. For all other permitted entry purposes — repairs, inspections, showings — the landlord must give at least 24 hours written notice and can only enter between 8 a.m. and 8 p.m. Entering without proper notice, other than in an emergency, is a violation of the tenant’s right to privacy under the RTA and can result in an LTB complaint.
