What Does It Mean to Withdraw a WSIB Claim in Ontario?
Withdrawing a WSIB claim does not automatically end a worker’s right to benefits — but the consequences depend heavily on the circumstances. In Decision No. 694/25, 2026 ONWSIAT 438 (CanLII) (link), the Workplace Safety and Insurance Appeals Tribunal examined what happens to entitlement when a worker at a winery withdrew their claim, and whether that withdrawal should be treated as final.
For injured workers, understanding the difference between withdrawing a claim and losing entitlement is critical. These are not the same thing, and conflating them can cost workers significant compensation.
What Is WSIAT and Why Does It Matter to Ontario Workers?
WSIAT — the Workplace Safety and Insurance Appeals Tribunal — is the final level of appeal for workers and employers who disagree with a WSIB decision. If WSIB denies your claim or reduces your benefits, WSIAT is where you go next.
The Tribunal is independent of WSIB and has the authority to overturn, vary, or confirm WSIB decisions. Its rulings set important precedents that affect how future claims are handled across Ontario. That is why decisions like this one matter even to workers who have never heard of the Tribunal.
Can a Worker Take Back a Withdrawn WSIB Claim?
In some circumstances, yes — a worker may be able to revisit entitlement even after a withdrawal. The key question WSIAT examines is whether the withdrawal was truly voluntary and informed, and whether the underlying entitlement to benefits still exists as a matter of law.
Withdrawals made under pressure, without proper legal advice, or based on a misunderstanding of the worker’s rights may be treated differently than a clear, deliberate decision to abandon a claim. Workers should never assume that signing off on a withdrawal closes the door permanently, especially if their condition worsens or new medical evidence emerges.
What Happened in This Case Involving a Winery Worker?
The worker in this case was employed at a winery when a workplace issue arose that led to a WSIB claim. At some point during the process, the claim was withdrawn. The central dispute before WSIAT was whether that withdrawal should stand and what effect it had on the worker’s entitlement to compensation.
WSIAT reviewed the record and considered the circumstances surrounding the withdrawal. The Tribunal’s analysis focused on the procedural and substantive fairness of what had occurred — examining whether the worker’s rights had been properly protected throughout the process. While the specific outcome turns on the facts of this case, the decision reinforces that withdrawals are not rubber-stamped by the Tribunal without scrutiny.
Does Working in Agriculture or at a Winery Affect WSIB Coverage in Ontario?
Agricultural workers in Ontario have had a complicated history with WSIB coverage, but that landscape has changed significantly in recent years. Most workers in agriculture — including those employed at wineries — are now entitled to WSIB coverage under Ontario law.
If you work at a winery, vineyard, or other agricultural operation and are injured on the job, you should not assume you fall outside the system. Coverage rules have expanded, and a failure to file — or an uninformed withdrawal — could mean losing benefits you are legally entitled to receive. Our Ontario employment lawyers can help you understand whether WSIB applies to your situation.
What Are the Most Common Mistakes Workers Make With WSIB Claims?
The most common mistake is not filing at all — or withdrawing too early without understanding the long-term consequences. Other frequent errors include:
- Failing to report the injury to the employer promptly
- Not seeking medical attention or documentation right away
- Accepting a return-to-work arrangement that is not medically appropriate
- Assuming a denial is final without appealing
- Withdrawing a claim under pressure from an employer or insurer
Each of these mistakes can seriously harm a worker’s ability to recover full compensation. The WSIB process has strict timelines, and delays or missteps early on can be very difficult to correct later.
Practical Takeaways for Injured Workers
If you have been injured at work in Ontario — or if you have already filed or withdrawn a WSIB claim — here are the key points to keep in mind:
- Never withdraw a claim without legal advice. A withdrawal can have lasting consequences on your entitlement to wage loss benefits, health care, and future coverage.
- A withdrawal is not always final. WSIAT can examine the circumstances of a withdrawal, and in some cases entitlement can still be addressed.
- Agricultural and winery workers are generally covered. Do not assume your workplace falls outside WSIB — check before you decide not to file.
- Keep records of everything. Medical reports, employer communications, and WSIB correspondence all matter at the appeal stage.
- Act quickly if you disagree with a WSIB decision. There are deadlines for appealing to WSIAT, and missing them can be fatal to your case.
