Can a WSIAT Review Change Whether You Qualify for Benefits?
Yes — the Workplace Safety and Insurance Appeals Tribunal (WSIAT) has the authority to re-examine whether an injury is work-related and whether a worker qualifies for benefits, even after an earlier decision has been made. A 2026 ruling, Decision No. 152/26, 2026 ONWSIAT 345 (CanLII) (read the decision), illustrates exactly how that redetermination process works in practice.
For injured workers in Ontario, this matters enormously. If you have been denied benefits — or had them reduced — the review process at WSIAT may be a path to a different outcome.
What Is WSIAT and How Does It Fit Into the Workers’ Compensation System?
WSIAT is the independent appeals body that reviews decisions made by the Workplace Safety and Insurance Board (WSIB). When a worker disagrees with a WSIB decision about their entitlement to benefits, they can appeal to WSIAT for an independent review.
WSIAT does not simply rubber-stamp the original decision. The tribunal examines the evidence afresh, considers whether the injury or illness is genuinely connected to the worker’s job, and can reach a different conclusion than the WSIB did. This independence is one of the most important protections available to injured workers in Ontario.

FAQ
Frequently asked questions
Generally, you have six months from the date of a WSIB decision to file an appeal with WSIAT, though the tribunal has discretion to extend this deadline in some circumstances. It is best to act quickly and seek legal advice as soon as you receive a decision you disagree with.
You are not required to have a lawyer, but legal representation can significantly improve your chances of success. A lawyer familiar with WSIAT proceedings can help you gather the right medical evidence and frame your arguments effectively.
In most cases, Ontario's workers' compensation system requires you to choose between WSIB benefits and a civil lawsuit against your employer — you generally cannot pursue both at the same time. There are limited exceptions, and a lawyer can help you understand which option is better for your situation.
