Many tenants in Manitoba face disputes that raise technical issues—like mold, structural repairs, or rental-unit habitability—where an expert witness can provide critical evidence. An expert witness is a qualified professional who explains technical findings in simple terms for the Residential Tenancies Branch[1] and helps the member decide complex issues. This guide helps tenants understand when an expert is useful, how to disclose reports and pay fees, and what the Branch expects at a hearing. It also points to the right forms and official resources so you can prepare evidence clearly and confidently as a renter in Manitoba.
What is an expert witness at the Manitoba LTB?
An expert witness is a professional—an engineer, building inspector, environmental consultant, or qualified tradesperson—who gives opinion evidence on technical matters beyond everyday knowledge. The Residential Tenancies Branch expects expert evidence to be relevant, reliable, and disclosed in advance under the applicable Manitoba tenancy rules and the Residential Tenancies Act[2]. Experts should explain methods, list qualifications, and attach photos, measurements and clear conclusions so the hearing member can follow the facts.
When an expert witness helps your case
- To prove habitability or safety problems like mold, water ingress, or structural defects where technical testing or inspection is needed.
- When reports, measurements, or lab results (e.g., mold testing or engineering assessments) are central evidence.
- When a landlord disputes responsibility and the member needs an impartial explanation of standards and repairs.
- To clarify safety or code compliance issues that affect habitability or tenant health.

How to prepare and bring an expert witness to a hearing
- Ask for a written report that explains the expert's qualifications, methods, findings, and clear conclusions you can share at the hearing.
- Disclose the expert report to the other party and file it with the Branch within the timelines the Branch sets so the hearing member and the other side can review it.
- Confirm filing and service deadlines early (for example, the Branch may require documents a set number of days before the hearing).
- Arrange payment: experts often charge for the report and hearing attendance; discuss fees and invoices before booking.
- Prepare the expert to give clear, plain-language evidence and to answer questions at the hearing from the member and the other party.
Fees, disclosure and evidence rules
- File and serve reports as the Branch requires; unclear disclosure can limit a report's weight at hearing.[3]
- The party calling the expert usually pays fees; you can ask the Branch for an order about costs after the hearing.
- Keep originals and supporting evidence: photos, receipts, lab results, inspection notes and the expert's CV or licence number.
- Explain how the expert applied accepted methods—judges and members rely on transparent methodology more than technical jargon.
