Ontario has some of the most tenant-protective rental legislation in North America. The Residential Tenancies Act (RTA), enforced by the Landlord and Tenant Board (LTB), sets strict rules around rent increases, evictions, notice periods, and maintenance obligations. For Ontario landlords, keeping accurate records isn't just good practice — it's your primary defence if a dispute ever ends up before the Board.
This guide covers what Ontario's tenancy law means for your day-to-day record-keeping, and what your software should be handling so you're always protected.
Ontario Rental Law: The Rules That Shape Your Records
Rent Increase Guidelines
Ontario limits rent increases to once every 12 months, and only up to the annual guideline set by the province. For 2025, the guideline was 2.5%. New builds (first occupied on or after November 15, 2018) are exempt from the guideline — but even exempt landlords must give 90 days' written notice before any increase.
What this means for your records: You must track the exact date rent was last increased for each unit, confirm the increase was within guideline (or that the unit qualifies for an exemption), and keep a copy of every N1 notice served. The LTB will ask for all of this if a tenant files an application.
Above-Guideline Increases (AGI)
Landlords can apply for above-guideline increases if they've made eligible capital expenditures — a new roof, HVAC system, or other major improvements. The AGI process requires detailed cost documentation submitted to the LTB.
What this means for your records: Capital expenditures need to be tracked separately from regular maintenance. If you're ever considering an AGI application, you need invoices, payment dates, and contractor information going back to the date of the work.
N Notices and LTB Forms
Ontario's eviction process runs entirely through standardized forms. Every notice — N4 (non-payment), N5 (damage or disturbance), N8 (persistent late payment), N12 (landlord's own use) — has specific wording requirements and must be served in a specific way.
Errors on these forms are grounds for dismissal at the LTB. Serving the wrong form, or the right form with wrong dates, restarts the process entirely.
What this means for your records: Keep a copy of every notice served, the date and method of service, and any response from the tenant. Your rent ledger — showing exactly which months were paid, partially paid, or missed — is the foundation of any N4 application.
Maintenance Obligations
The RTA requires landlords to keep rental units in a good state of repair and comply with all property standards. Tenants can file T6 applications (maintenance) if a landlord fails to maintain the unit — and the LTB can order rent abatements going back 12 months.
What this means for your records: Log every maintenance request, when it was received, and when it was resolved. A documented repair history is your defence against a T6 application.
CRA Requirements: Federal Rules Apply Across Ontario
Provincial tenancy law governs your relationship with tenants. Federal CRA rules govern your taxes. Both apply at the same time.
As an Ontario landlord, you file CRA Form T776 (Statement of Real Estate Rentals) for each rental property alongside your T1 General. Ontario has no separate provincial rental income form — it all flows through your federal return.
Ontario-specific T776 considerations:
Municipal Land Transfer Tax paid on acquisition is not deductible — it's added to your adjusted cost base. Toronto LTT (if applicable) is treated the same way. MPAC property assessments set your property tax base — track annual property tax payments carefully as they're fully deductible on T776.
What Ontario Landlords Specifically Need from Software
Beyond standard Canadian landlord requirements, Ontario landlords have specific record-keeping needs:
Rent increase history per unit. The date of every increase, the amount, and whether the unit is exempt from guideline. Essential for proving compliance if a tenant files an A1 application.
Clean rent ledger exportable by unit. The LTB expects clear evidence of payment history. A per-unit ledger showing every entry — paid, partial, or missed — is exactly what an L1 (eviction for non-payment) application requires.
Maintenance log. Date received, date resolved, work done. Timestamped records are far more credible at the Board than verbal recollections.
T776 expense tracking mapped to CRA categories. Capital expenditures tracked separately from repairs — important if you ever pursue an AGI application.
The LTB Backlog Reality
Ontario's LTB has faced significant hearing backlogs in recent years. Cases that once resolved in 60–90 days can now take six months or longer. This means disputes drag out — and the landlord with better documentation almost always wins.
If you've been operating informally — tracking rent in your head, logging expenses on a spreadsheet — a single LTB dispute will expose every gap in your records. The time to build a proper system is before you need it, not after a tenant has already filed.
