Plain-language answer
Preparing evidence for the Landlord and Tenant Board is mostly a job of selecting, organizing, and delivering on time. The LTB has rules about how and when evidence must be submitted — generally in advance of the hearing, to both the Board and the other party. Because these rules and deadlines are updated from time to time, always check the current instructions on the LTB website or your Notice of Hearing.
Select evidence that proves specific points: dated photos, payment records, notices, messages, inspection reports. For each document ask, "What fact does this establish?" If you cannot answer, it may not belong. Arrange everything chronologically or by issue, number the pages, and prepare a short index.
Witnesses count as evidence too. If someone saw what happened, plan how they will attend, and let them know they may be questioned by the other side and the Member.
Why it matters
Evidence that is not submitted properly and on time may not be considered at all — strong facts can be lost to weak logistics.
Organized evidence also changes how a hearing feels: instead of searching through a phone while the Member waits, you cite "page 4, the March 3 photo" and keep your credibility.
Facts that affect the answer
Based on the information available, these are the kinds of facts that commonly change how a situation like this is assessed:
- The LTB's current evidence deadlines and submission methods, stated on your Notice of Hearing and the LTB website.
- Whether the other side received copies of your evidence as required.
- Whether your documents are legible, dated, and complete — cropped or undated items carry less weight.
- Whether witnesses can actually attend in the hearing's format (video, phone, or in person).
- Whether your evidence addresses the issues in the application, not just your general grievances.
Evidence to preserve
Preserve these now, in their original form
- Proof that you submitted your evidence — confirmation emails, upload receipts, or delivery records.
- A numbered master copy of your evidence package with an index.
- Originals of everything, even after copies are filed.
- Contact details and availability notes for each witness.
- The other side's evidence, kept together with your notes on it.
Common mistakes
- Missing the submission deadline and hoping the Member will accept documents at the hearing anyway.
- Submitting everything you have — hundreds of unsorted photos can bury the three that matter.
- Forgetting to give the other party copies when the rules require it.
- Relying on a witness's availability without confirming, or assuming a written statement will carry the same weight as live testimony.
- Leaving preparation until the week of the hearing, when clinics are hardest to reach.
Possible official process
Check your Notice of Hearing and the LTB website for current evidence rules and deadlines, and follow the stated submission channels exactly.
Serve the other party as required and keep proof of service or delivery.
If you miss a deadline or new evidence appears late, get advice quickly — the Board has discretion in some circumstances, but nothing is guaranteed.
