Can WSIAT Cut Off Benefits If You Refuse Modified Work in Ontario?

What Happens to Your WSIB Benefits If You Refuse Modified Work?

Refusing modified duties your employer offers can result in a reduction or suspension of your WSIB loss-of-earnings benefits. In Decision No. 414/26, 2026 ONWSIAT 600 (CanLII), Ontario’s Workplace Safety and Insurance Appeals Tribunal (WSIAT) addressed exactly this situation — an injured worker with a compensable low back impairment was offered modified duties by their employer, and the Tribunal had to decide whether those duties were appropriate and what the refusal meant for the worker’s benefits.

This is one of the most common and consequential issues in Ontario workers’ compensation law. Understanding how it works can protect your income while you recover.

What Are “Modified Duties” Under Ontario’s Workers’ Compensation System?

Modified duties are adjusted job tasks that an employer offers to an injured worker so they can return to work without aggravating their injury. Under Ontario’s Workplace Safety and Insurance Act, both employers and workers have return-to-work obligations. The employer must offer work that fits within the worker’s functional limitations, and the worker must make genuine efforts to participate in the return-to-work process.

Modified duties are not the same as the worker’s pre-injury job. They are meant to be lighter, safer, or restructured in a way that respects medical restrictions — for example, avoiding heavy lifting for someone with a back injury.

Does the Employer Have to Prove the Modified Work Is Suitable?

Yes — the modified duties must genuinely match the worker’s compensable restrictions, and the Tribunal will scrutinize whether that standard is met. In this case, the Tribunal examined whether the duties offered were consistent with the functional limitations caused by the worker’s low back impairment. The Tribunal concluded they were.

This is an important protection for workers. An employer cannot simply point to any available light-duty position and call it suitable. The work must be tailored to what the worker’s specific, compensable injury actually allows.

What Medical Evidence Do You Need to Justify Refusing Modified Work?

To successfully refuse modified duties without losing benefits, you generally need objective medical evidence showing that the offered work exceeds your functional limitations. A note from your treating physician or specialist explaining why the specific duties are beyond your restrictions carries significant weight at the Tribunal.

Subjective reports of pain or fear of re-injury, while understandable, are typically not enough on their own. The Tribunal will look for medical documentation that clearly links your restrictions to the compensable injury and explains why the offered duties are inconsistent with those restrictions.

Can You Lose Benefits Even If Your Injury Is Real and Serious?

Yes — benefit entitlement and the seriousness of your injury are separate questions. Even if your low back injury is genuine and compensable, your loss-of-earnings benefits can still be reduced if the Tribunal finds that suitable modified work was available and you refused it without adequate medical justification.

This is a critical distinction many workers miss. WSIB is not simply about whether you are injured — it is also about whether you are cooperating with the return-to-work process. Our Ontario employment lawyers regularly help workers understand these obligations before they make decisions that affect their benefits.

What Should You Do If Your Employer Offers Modified Duties?

Do not refuse modified duties without first getting legal and medical advice. The consequences can be immediate and financially significant. Before you respond to your employer’s offer, speak with your treating physician about whether the specific duties are within your restrictions, and consider consulting an employment lawyer who understands the WSIB system.

Practical Takeaways for Injured Workers

• Get medical documentation before refusing. If you believe the modified duties exceed your restrictions, ask your doctor to put that opinion in writing with specific reference to the offered tasks.
• Do not ignore the employer’s offer. Even if you think the work is unsuitable, formally responding and documenting your concerns protects your position at the Tribunal.
• Review the functional abilities form. The WSIB functional abilities form sets out your restrictions — compare it carefully against what the employer is asking you to do.
• Act quickly. Return-to-work timelines matter. Delays in responding to a modified work offer can be interpreted as non-cooperation.
• Get legal advice early. A WSIB appeal is a formal legal process. Speaking with an employment lawyer before your hearing — not after — gives you the best chance of protecting your benefits.
