Most landlord losses at the Landlord and Tenant Board come from preventable procedural errors — not bad luck. Here's a plain-English walkthrough of the parts of Ontario's Residential Tenancies Act that matter most for GTA condo investors.

The Residential Tenancies Act, 2006 ("RTA") is the single most consequential piece of legislation in an Ontario condo investor's life. It governs your relationship with your tenant, your obligations as a landlord, your rights when something goes wrong, and — most importantly — the procedural rules you must follow to enforce any of it.
This guide is a working reference for GTA condo owners. It isn't legal advice; for matters involving an active dispute or hearing, you should consult a paralegal or lawyer (CentreKey owners get direct access to in-house paralegal expertise). But for the everyday questions that owners face, the material below covers what you need to know.
The RTA applies to most residential rental relationships in Ontario, including condominium units rented to a tenant. It sets out the legal framework for tenancy creation, rent payment, maintenance obligations, dispute resolution, and termination — and it gives the Landlord and Tenant Board ("LTB") the authority to adjudicate disputes.
What it doesn't cover: short-term rentals (Airbnb-style stays), commercial tenancies, owner-occupied situations where the tenant shares the kitchen or bathroom with the owner, and certain transitional housing arrangements. If you're operating a short-term rental, you're under municipal short-term rental rules — not the RTA.
Since April 30, 2018, almost all Ontario residential leases must use the Ontario Standard Lease form. It's a fillable, government-issued template that covers the essentials: parties, property, term, rent, services and utilities, deposit, and signatures.
What you can do: add an addendum with additional terms — pet rules, smoking policy, condo board rules, etc. — but those additional terms cannot conflict with the RTA. A clause saying "no children" or "no overnight guests," for instance, is unenforceable.
What you can't do: use a non-standard lease form. If you fail to provide a Standard Lease within 21 days of a written request from the tenant, the tenant may withhold one month's rent.
Ontario sets an annual rent increase guideline — the maximum percentage by which a landlord can raise rent on a non-exempt unit each year. The 2026 guideline is 2.5%.
To raise rent in compliance with the RTA, the landlord must:
Building Exemption — The Key Carve-out
- Buildings first occupied on or after November 15, 2018 are exempt from the rent increase guideline.
- For exempt units, you can raise rent by any amount — but the 90-day N1 notice rule still applies.
- This exemption applies to the building's first occupancy date, not the date you bought your unit.
- Many newer downtown Toronto condos qualify; if in doubt, check with a paralegal before pricing your renewal strategy.
This is the rule landlords break most often, usually unintentionally.
Under section 27 of the RTA, a landlord may only enter a rented unit:
The 24-hour notice must be in writing, must specify the reason for entry, and must specify the time of entry within the 8 a.m. – 8 p.m. window. A text message can satisfy the "in writing" requirement; a phone call cannot.
If your tenant misses rent, here's the timeline:
Most leases set rent due on the 1st of the month. If the rent isn't received by end-of-day on the due date, the tenant is technically in breach.
The N4 ("Notice to End your Tenancy Early for Non-payment of Rent") gives the tenant 14 days to either pay the arrears in full or vacate. The N4 must specify the exact amount owed and the period it covers. An incorrectly calculated N4 is invalid — and a fresh, properly drafted notice has to be served, restarting the clock.
If the tenant hasn't paid by day 14, you can file an L1 application with the LTB to terminate the tenancy and collect arrears. Filing fees apply. Wait times vary — historically months, now improved but still material.
At the hearing, the LTB may issue an order for payment, an eviction, or both. Even if the tenant pays the full arrears before the hearing, the order may still issue if the LTB finds the tenant has a pattern of late payment.
The most powerful — and most-abused — landlord notices are the N12 (personal use by landlord, immediate family member, or purchaser) and the N13 (major repairs, demolition, or conversion).
Both notices require:
If the LTB later determines that an N12 was filed in bad faith — for example, the unit was re-listed for rent within 12 months — significant penalties apply, including potential lifetime bans on rent increases and substantial fines.
The RTA isn't actually a complicated piece of legislation. The complications come from procedure — the form numbers, the timing windows, the documentation standards. Owners who keep clean documentation almost always succeed at the LTB. Owners who don't, almost always lose, regardless of the underlying merits.
This is one of the reasons we exist. Procedural compliance shouldn't be the thing that determines whether your investment performs.

The Residential Tenancies Act, 2006 is the Ontario law that governs most residential rentals, including condos. It sets the rules for rent increases, evictions, maintenance, entry, and deposits, and it overrides any conflicting lease clause. Disputes under the RTA are resolved by the Landlord and Tenant Board (LTB).
Yes. A rented condo unit is covered by the RTA just like an apartment. Your tenant also has to follow the condo corporation's declaration, bylaws, and rules — but as the owner, you remain responsible to both the corporation and the LTB.
Keep the unit in good repair, use the Ontario Standard Lease, give proper written notice before entering (generally 24 hours), follow the rent increase rules and notice periods, and use the correct LTB forms and process for any termination. Procedural mistakes are the most common reason landlords lose at the LTB.
The RTA wins. Any lease term that takes away a right the RTA gives a tenant — such as banning pets outright or requiring a damage deposit — is void and unenforceable, even if the tenant signed it. The rest of the lease remains valid.
