How Alberta Tenants Can Reopen a Closed LTB Case

Dispute Resolution & LTB Alberta 5 min read · published March 09, 2026 Flag of Alberta

When a case with Alberta’s landlord-tenant tribunal is closed, tenants sometimes wonder if they have any options left to address injustice or correct a mistake. Whether your application was dismissed, a decision went against you, or you missed a hearing, Alberta law provides ways for tenants to request a review or reopening of their case.

Understanding Dispute Resolution in Alberta

In Alberta, landlord and tenant disputes are handled by the Residential Tenancy Dispute Resolution Service (RTDRS), a tribunal empowered to resolve many residential tenancy conflicts. The governing law is the Residential Tenancies Act (RTA)[1]. Unlike the "LTB" in Ontario, Alberta tenants use the RTDRS or the provincial courts to resolve rental disagreements.

Can a Closed RTDRS Case Be Reopened?

Yes, in certain circumstances, tenants can apply to have a closed RTDRS case reconsidered. The most common reasons include:

  • Missing a hearing due to circumstances beyond your control.
  • New evidence not available at the original hearing.
  • A clear error in the original decision or procedural unfairness.

If you believe a mistake has been made or you were not given a fair chance to present your case, it's important to act quickly, as there are short deadlines to submit a review request.

Deadlines to apply for a review are tight: Form 25 must be filed within 5 days of becoming aware for possession orders, or 20 days for other orders. Gather supporting documents such as the order notice and any medical or service-related evidence to strengthen your request.
If you’re unsure which form to use, contact the RTDRS directly for guidance, as deadlines are strict and missing them can end your options for review.

Key Forms and How to Use Them

Alberta provides specific forms for tenants to challenge, appeal, or request a rehearing of a closed RTDRS case. Here are the main options:

1. Request to Set Aside or Vary an Order (Form 25)

  • What it's for: Asking the RTDRS to cancel or change an order due to circumstances like not being served properly, not attending the hearing due to exceptional reasons, or evidence of mistake.
  • How to use it: Complete Form 25 – Request to Set Aside or Vary an Order within 5 days (for possession orders) or 20 days (other orders) after becoming aware of the order.
  • Example: If you missed your hearing because you were hospitalized and only learned of the decision after, submit Form 25 right away with supporting documentation.

2. Notice of Appeal (Provincial Court)

  • What it's for: If you believe the RTDRS made a legal or jurisdictional error, you may appeal to the Court of King's Bench.
  • How to use it: File a written "Notice of Appeal" with the court within 30 days of the RTDRS order being given. Details are on the RTDRS official appeals page.
  • Example: If your landlord’s evidence was accepted but yours was not heard, and you suspect a serious error, consider this step (often with legal advice).
If you’re unsure which form to use, contact the RTDRS directly for guidance, as deadlines are strict and missing them can end your options for review.

Eligibility and Deadlines

It’s critical to take prompt action. Key deadlines include:

  • Form 25 (to set aside/vary an order): 5 days for possession orders, 20 days for other types.
  • Appeal to court: Within 30 days of the date of the original RTDRS order.

Attach any evidence explaining why you missed the deadline or why the original outcome should be reconsidered. Be clear, concise, and honest in any statements you provide.

Missing deadlines can end your right to reopen; keep a deadline calendar and set reminders for each step (Form 25 5 days/20 days; appeal to court within 30 days).

Practical Steps for Tenants

Reopening a case can seem intimidating, but it is meant to protect your right to fair treatment. Steps commonly include:

  • Carefully read the RTDRS decision notice for details on deadlines and next steps.
  • Gather all documents, evidence, and any new information not available at the original hearing.
  • Download and fill out the appropriate form (usually Form 25) from the RTDRS Forms page.
  • Contact RTDRS at 1-780-644-3000 (Edmonton) or 1-855-738-7837 (toll free) if you have questions.
  • Submit the form and evidence before the deadline, as late submissions are rarely accepted.
Insight: Start gathering evidence early—keep copies of notices, medical records, and written explanations, and note dates you spoke with RTDRS for reference.
