How to Document Apartment Conditions for an LTB Application

Why documentation matters so much at the LTB

At an LTB hearing, an adjudicator is generally working from whatever evidence the parties bring — there's usually no independent inspector sent out beforehand to confirm who's right about a disputed condition. This means that a tenant's account, however accurate, carries more weight when it's backed by specific, dated, and verifiable evidence rather than general description alone. "The apartment has had a mould problem for months" is a claim; dated photos showing the mould's progression, alongside written notices sent to the landlord and the landlord's responses (or lack of response), is evidence an adjudicator can actually evaluate.

This matters whether a tenant is the one applying (for example, a T6 about maintenance) or responding to a landlord's application and raising a condition issue as part of a defence. Either way, the burden of connecting the dots for the adjudicator falls on whoever is relying on the facts, and documentation is how that connection gets made convincingly.

Photo and video evidence: doing it well

Photos and short videos are often the most persuasive evidence a tenant can gather, but their usefulness depends heavily on how they're taken and preserved. Each photo should ideally be dated (most phones embed this automatically, but it's worth double-checking settings), taken from a distance that shows context as well as close-up detail, and repeated over time if the condition is ongoing or worsening, so the sequence itself tells a story. For issues like leaks, pests, or mould, a short video can sometimes capture things a still photo can't, such as active dripping or movement.

It's also worth photographing anything that shows the broader context — a thermostat reading during a heating failure, a calendar or newspaper in frame to help establish a date if metadata isn't reliable, or the general state of a room rather than only the specific defect. This kind of contextual evidence tends to pre-empt an easy objection that a photo could have been taken at any time or doesn't show what it's claimed to show.

Keeping a written log over time

A simple, contemporaneous written log is one of the most underused but effective tools a tenant has. This doesn't need to be formal — a running note on your phone or a notebook entry each time something happens is enough. Each entry should generally include the date, what was observed or happened, and any action taken (a call, a text, a maintenance request). Over weeks or months, this log becomes a timeline an adjudicator can follow far more easily than trying to reconstruct events from memory at a hearing many months later.

A log is especially valuable because memory naturally fades and can be challenged, while a dated, contemporaneous record carries more weight precisely because it wasn't created after the fact with the benefit of hindsight.

Saving communications with your landlord

Every text, email, or written note exchanged with a landlord about a condition issue is potential evidence, and it's worth preserving all of it rather than deleting old conversations. Where a conversation happens verbally or by phone, following up afterward with a short written message summarizing what was discussed ("Just following up on our call — I mentioned the heat has been out since Tuesday and you said someone would come by Thursday") creates a written record even for conversations that weren't originally in writing. This habit converts an otherwise unprovable verbal exchange into something a tenant can actually point to later.

Third-party evidence that can strengthen a case

Beyond a tenant's own photos and notes, independent evidence can add real credibility. A municipal property standards complaint and any resulting inspection report is often strong evidence, since it comes from a neutral source rather than the tenant directly. Receipts for anything purchased because of the problem — a space heater, a dehumidifier, pest control products, a hotel stay — help substantiate both that the problem existed and what it cost. In some cases, a written statement from a neighbour who witnessed relevant events (such as repeated pest sightings in a shared area) can also help, though this is generally most useful when it's specific and dated rather than vague.

Organizing evidence for the hearing itself

Having good evidence doesn't help much if it's disorganized at the hearing. Generally, it's worth assembling evidence into a simple chronological package — a written timeline summary at the front, followed by supporting photos, logs, and communications in date order. Making a copy for the landlord (or their representative) and the adjudicator, as required by the LTB's disclosure rules, and knowing roughly what each piece of evidence is meant to show, makes a real difference in how smoothly a hearing goes. An adjudicator with limited time generally responds better to a tenant who can point directly to "this photo, taken on this date, shows X" than to someone fumbling through an unsorted phone gallery live at the hearing.

Common pitfalls that weaken otherwise good evidence

A few recurring issues can undercut even genuinely strong evidence. Undated or inconsistently dated photos make it hard to establish a timeline. Evidence gathered only right before the hearing, with no earlier record that the landlord was ever notified, can make it look as though the issue wasn't raised at the time it occurred. Exaggeration or including irrelevant complaints alongside the real issue can distract from a legitimate claim and make an adjudicator more skeptical generally. Finally, failing to provide the other party with copies of evidence in advance, where required, can result in that evidence not being accepted at the hearing at all — so understanding and following the LTB's disclosure requirements matters just as much as gathering the evidence in the first place.

Timing: start now, not the week before

The single best piece of practical advice is to start documenting as soon as an issue arises, not once a hearing is already scheduled. Evidence gathered in the moment is almost always stronger than evidence reconstructed after the fact, and starting early also gives a tenant a better sense of whether the issue is resolving, worsening, or being ignored — which itself shapes whether and when an LTB application makes sense in the first place.

It can also help to think of documentation as an ongoing habit rather than a one-time task tied to a single incident. A tenant who keeps a simple running file — whether a folder of photos organized by date, a notes app entry, or a physical folder of printed emails — finds it much easier to respond quickly if a dispute suddenly accelerates, such as a landlord unexpectedly filing an application. Waiting to organize everything only once a hearing date is confirmed often means trying to reconstruct months of history under time pressure, which is both stressful and more error-prone than building the record gradually as events happen.
