In Ontario, understanding whether a living arrangement falls under the statutory scope of the Residential Tenancies Act, 2006 (RTA) is a fundamental prerequisite before enforcing lease terms, adjusting rent, issuing notices, or filing disputes.
When ambiguity arises regarding whether an occupancy arrangement is covered by the RTA, landlords or occupants can file an A1 Application (Application about Whether the Act Applies) with the Landlord and Tenant Board (LTB) to establish official jurisdiction.
At Lex Defensio, we advise property owners, residential landlords, and corporate property managers across Ontario. We evaluate coverage criteria, prepare A1 submissions, and represent property owners before the LTB to establish jurisdiction and uphold regulatory compliance.
Statutory Scope & Primary Exemptions (RTA Section 5)
While the RTA governs most private residential rental units in Ontario—including high-rise apartments, basement suites, condominiums, and single-family rental homes—Section 5 of the RTA explicitly excludes several types of living arrangements.
- LTB Standard Lease Rules
- Formally Restricted Evictions
- Guideline Rent Protections
- Standard LTB Form Notices
- Shared Kitchen/Bath with Owner
- Commercial / Incidental Units
- Short-Term / Vacation Living
- Common Law Contract Remedies
Primary Statutory Exemptions Under RTA Section 5
| Exemption Category | Statutory Provision | Key Legal Determinants & Thresholds |
|---|---|---|
| Shared Living Facilities | RTA s. 5(i) | Living accommodation where the occupant is required to share a kitchen or bathroom facility with the owner, the owner’s spouse, child, or parent, or the spouse’s child or parent residing in the same building. |
| Business / Commercial Premises | RTA s. 5(a) | Premises intended to be used for business, commercial, or agricultural purposes where residential occupancy is purely incidental to the commercial operation. |
| Temporary & Vacation Stays | RTA s. 5(a), (a.1) | Living accommodations intended for seasonal, vacation, or short-term emergency shelter purposes. |
| Educational & Institutional | RTA s. 5(g), (h) | Student accommodations provided by universities, colleges, or schools, as well as care facilities or medical institutions under specific conditions. |
The Substance-Over-Form Doctrine (RTA Section 202)
When adjudicating an A1 application to determine whether the RTA applies, the Landlord and Tenant Board applies Section 202 of the RTA, known as the Substance Over Form rule:
RTA Section 202(1):
“In making findings on an application, the Board shall ascertain the true substance of all transactions and activities relating to a residential complex or a rental unit and may disregard the outward form of a transaction or agreement.”
Even if a written agreement is labeled a “Roommate Agreement,” “Commercial Lease,” or “License to Occupy,” the LTB will examine the physical layout, day-to-day living reality, financial transactions, and actual usage to decide whether the RTA applies.
Step-by-Step LTB A1 Application Workflow
1.1. Property Layout & Fact-Finding Audit:Legal Assessment.
Audit the physical layout of the property, utility sharing, door access, lease contracts, and family relationships to determine whether statutory exemptions under Section 5 apply.
2.2. Draft LTB Form A1 Package:Form Preparation.
Complete Form A1 (Application about Whether the Act Applies), explicitly detailing the physical setup, common area arrangements, and statutory grounds for inclusion or exemption.
3.3. File Application & Pay Filing Fee:Filing & Service.
Submit the application through the Tribunal-Customer Portal (NAV-LTB) along with the mandatory filing fee. Serve the application package and Notice of Hearing on all named parties in compliance with LTB Rules of Practice.
4.4. File Evidentiary Briefs:Evidence Assembly.
Upload floor plans, utility records, text messages, photographs of shared facilities, proof of ownership, and sworn affidavits detailing facility sharing prior to the hearing deadline.
5.5. LTB Hearing & Order Issuance:Board Adjudication.
Present oral arguments and evidence before an LTB Adjudicator. The Board renders a binding Order declaring whether the tenancy is subject to the RTA.
Strategic Significance of the A1 Determination
Establishing whether a tenancy falls under the RTA shapes the legal options available to landlords and property managers:
- When the RTA Applies:
- Rent increases must comply with statutory guidelines (or new-build exemptions under s. 6.1).
- Evictions require formal LTB notices (N4, N5, N8, N12) and binding LTB eviction orders.
- Security deposits are strictly limited to a last month’s rent deposit (LMR).
- When the RTA Does Not Apply:
- The relationship is governed by common law contract principles and the specific terms of the written occupancy agreement.
- Landlords do not use LTB N-forms or file LTB applications.
- Disputes are handled through private contract resolution, common law notice procedures, or the Ontario Small Claims Court / Superior Court of Justice.
