If you manage rental units in Ontario, your landlord maintenance obligations Ontario-wide are set out in the Residential Tenancies Act, 2006 (RTA), and the Landlord and Tenant Board (LTB) has grown noticeably less forgiving about how those duties are documented. Section 20 of the RTA is short but sweeping: a landlord must keep the rental unit and the residential complex in a good state of repair, fit for habitation, and compliant with health, safety, housing and maintenance standards - whether or not the tenant knew about a problem before moving in. In 2026, the real risk for property managers is not the repair itself. It is the gap between doing the work and being able to prove you did it to the Board's satisfaction.
What Section 20 of the RTA actually requires
The wording of Section 20 does three things at once, and each one is enforceable on its own:
- Good state of repair. The unit and common areas must be kept functional and safe, from the roof and plumbing to appliances the landlord supplies.
- Fit for habitation. Even if a component technically works, conditions that make a unit unlivable (pest infestations, mould, no functioning heat) fail this test.
- Compliance with standards. This pulls in provincial maintenance standards and any local property standards bylaw.
A point that catches out new managers: the obligation applies even when the tenant accepted the unit "as is" or noticed the defect before signing. You cannot contract out of Section 20. A clause in a lease saying the tenant is responsible for a landlord-side repair is void, and the LTB will treat it as if it were never written.
Repairs versus maintenance standards
There are two overlapping rulebooks. First, the RTA's general repair duty. Second, the actual maintenance standards. Where a municipality has its own property standards bylaw enforced by a property standards officer, that bylaw governs. Where it does not, Ontario's provincial Maintenance Standards regulation applies, and the LTB can enforce it directly. As a practical matter, you should know which regime covers each property you manage, because it changes who inspects, who issues work orders, and what timelines you are held to.
Vital services and heat
Vital services (heat, hot and cold water, electricity, and fuel such as gas) sit in their own category. A landlord who is obligated to supply a vital service cannot deliberately interfere with it, full stop. Heat has a specific benchmark that most Ontario managers should have memorized: the regulated minimum is at least 20 degrees Celsius from September 1 to June 15. If your tenant reports an under-heated unit in that window, treat it as urgent, not routine. Vital-service complaints are among the fastest to reach the Board and among the least sympathetic to a landlord who dragged their feet.
What the LTB expects on evidence in 2026
Here is the shift that matters. Tenants raise maintenance disputes through a T6 application (Tenant Rights). When one lands, the Board is not asking "did a problem exist?" nearly as often as it is asking "what did the landlord do, when, and can they show it?" Adjudicators increasingly expect a documented paper trail rather than a manager's recollection.
In practice, the evidence that holds up looks like this:
- Dated intake of the complaint - the tenant's message, a maintenance ticket, or a logged call with a timestamp.
- Proof of response time - when you acknowledged it and when you dispatched someone.
- Scope and diagnosis - what the contractor found, in writing, ideally with photos before work started.
- The fix - invoices, work orders, and photos of the completed repair, dated.
- Compliance sign-off where required - an Electrical Safety Authority (ESA) notification for electrical work, a Technical Standards and Safety Authority (TSSA) record for gas or fuel appliances, and documentation for smoke and carbon monoxide alarms.
When this trail is clean, a T6 that might have led to a rent abatement often resolves in the landlord's favour or settles quickly. When it is missing, the Board tends to side with the tenant's version of events, because the landlord had the ability to keep records and did not.
Meeting your landlord maintenance obligations Ontario PMs can defend
Satisfying your landlord maintenance obligations Ontario law imposes is really two jobs: fix things properly, and build a defensible record while you do. Use this as a standing checklist across your portfolio.
- Log every complaint the moment it arrives. A shared inbox or ticketing system beats scattered texts. The timestamp is your friend at a hearing.
- Triage by urgency. Vital services, fire safety, and habitability issues get same-day or next-day attention. Cosmetic and non-urgent items get a reasonable, communicated timeline.
- Photograph before and after. A dated photo of the failed component and the completed repair is the single most persuasive piece of evidence you can produce.
- Keep a maintenance file per unit. Invoices, contractor reports, ESA and TSSA records, alarm test logs, and inspection notes, all in one place.
- Test life-safety devices on schedule. Smoke and carbon monoxide alarms are a landlord duty under Ontario's fire rules. Missed testing is an easy, avoidable finding against you.
- Communicate delays in writing. If a part is on backorder, tell the tenant and note it. A documented reasonable effort is very different from silence.
- Close the loop. Confirm with the tenant that the issue is resolved, and record their confirmation.
A quick note for managers scaling this across many doors: our Canadian property managers hub walks through how to standardize intake, dispatch, and record-keeping so the same evidence trail is produced every time, not just when someone remembers.
Vetting contractors who can document to the standard
Your compliance record is only as strong as the trades who create it. A contractor who fixes the leak but never sends a dated invoice or photo has left you exposed. When you are choosing who works on your units, weigh their documentation and licensing discipline as heavily as their price. The best trades treat clean paperwork as part of the job, and the way a contractor runs the back office often signals how they will run the repair; if you want to understand what separates a well-run trade business from a shaky one, Construction Arbitrage is a useful read on the operational side.
This is also where a marketplace earns its keep. Rather than cold-calling and hoping, platforms like PlanaJob let property managers compare quotes from vetted contractors side by side, so you can weigh price, availability, and credentials before you commit. You can browse more compliance and operations guidance on the PlanaJob blog, and when you are ready to raise a job, creating a free account takes only a few minutes.
The deeper reason to work this way is evidentiary. Planajob matches you with vetted contractors who document repairs to LTB evidentiary standards, which means the before-and-after photos, dated invoices, and scope notes you would need at a hearing are generated as a byproduct of the job rather than reconstructed after a T6 lands. In 2026, that is the difference between a defensible file and a scramble.
FAQ
Can a tenant withhold rent in Ontario if repairs are not done?
No. Ontario tenants are not permitted to unilaterally withhold rent over maintenance issues, and doing so can expose them to their own consequences. The proper route is a T6 application to the LTB, which can order repairs, a rent abatement, or other remedies. As a manager, do not treat non-payment as evidence you are off the hook; the underlying repair duty still stands.
What is the difference between the LTB and a municipal property standards officer?
The LTB resolves disputes between landlords and tenants under the RTA, including maintenance applications. A property standards officer enforces a municipality's own property standards bylaw and can issue work orders directly, separate from any tenant application. You can face both at once, so treat a bylaw work order as urgent even if no tenant has complained.
How long should I keep maintenance records for a unit?
Keep them for as long as the tenancy lasts and well beyond it, since a dispute can be filed after the fact and limitation periods apply. A per-unit file with dated complaints, invoices, photos, and compliance sign-offs is inexpensive to maintain and invaluable if your landlord maintenance obligations Ontario requires are ever questioned at a hearing.
