Commercial divers in Ontario are fully covered by the Workplace Safety and Insurance Board (WSIB) for acute and chronic occupational injuries, including decompression sickness (the bends) and barotrauma. WSIB generally pays for emergency hyperbaric chamber treatments, specialized medical care, and Loss of Earnings (LOE) benefits while you recover.
Commercial diving and underwater welding are among the most dangerous professions in Canada. Whether you are maintaining infrastructure in the freezing waters of Lake Superior near Thunder Bay, inspecting pipelines in Sarnia, or doing deep-water recovery in Toronto, the physical toll on your body is immense. Unlike standard workplace accidents, diver injuries are highly specialized. A sudden change in pressure can lead to life-threatening conditions like decompression sickness (DCS) or severe barotrauma to the ears, lungs, and sinuses.
Because diving injuries require immediate, hyper-specialized treatment, navigating the WSIB claims process can feel overwhelming. Many divers do not realize that the WSIB formally recognizes specific occupational diseases related to diving, meaning you do not always need to prove a single “accident” occurred if you develop chronic joint issues later in life. 📍 It is highly advisable to seek guidance from an experienced local WSIB lawyer from our directory to ensure your complex medical evidence is properly presented and your right to specialized care is protected.
Step-by-Step Process for Diver WSIB Claims in Ontario
Filing a claim for a diving injury requires swift action. Whether you are working in Kingston, Sudbury, or Hamilton, the WSIB treats decompression illnesses as medical emergencies. Follow these steps to secure your entitlements.
Step 1: Seek Emergency Hyperbaric Treatment
Your immediate health is the absolute priority. If you experience symptoms of decompression sickness (joint pain, dizziness, paralysis) or severe barotrauma, go to the nearest emergency room or designated hyperbaric chamber facility immediately. Ensure the attending physician explicitly notes that the injury occurred while diving for work. This medical record is the foundation of your WSIB claim.
Step 2: Notify Your Employer Immediately
Under Ontario law, you must report the injury to your employer as soon as possible. Your employer is legally required to submit a Form 7 (Employer’s Report of Injury/Disease) to the WSIB within three days of learning about an injury that requires more than first aid. If your employer hesitates or tries to convince you to handle it privately, refuse their offer and report it anyway.
Step 3: Submit Your Form 6 to the WSIB
You must fill out and submit a Form 6 (Worker’s Report of Injury/Disease). This form tells the WSIB your side of the story. You must detail your dive logs, the depths you reached, the equipment used, and the exact moment you noticed symptoms. For chronic conditions like dysbaric osteonecrosis (bone death caused by nitrogen bubbles), you will need to list your entire diving employment history.
Step 4: Gather Specialized Medical Evidence
WSIB adjudicators are not diving experts. Your law firm will help you coordinate with a diving medical specialist (such as a physician trained in hyperbaric medicine) to provide a detailed medical report. This report must explicitly link your current diagnosis, whether it is neurological damage or hearing loss, to the physical hazards of commercial diving.
How Much Does it Cost in Ontario?
Suffering a severe diving injury can completely halt your income. Understanding the financial coverage provided by WSIB is crucial.
- Medical Costs: WSIB covers 100% of approved medical costs, including hospital stays, hyperbaric oxygen therapy, prescription medications, and specialized hearing aids if barotrauma causes deafness.
- Loss of Earnings (LOE): If you cannot dive, WSIB pays 85% of your net average earnings, up to an annual maximum ceiling (which is periodically adjusted for inflation, officially $121,700 CAD for 2026).
- Travel Expenses: WSIB generally reimburses travel costs (mileage and lodging) if you must travel from a remote work site to a specialized hyperbaric chamber in a major city.
- Lawyer Fees: If your WSIB claim is denied and you must appeal, most WSIB lawyers work on a contingency fee basis, usually charging between 15% and 30% of your retroactive lump-sum settlement.
Comparing Diving Injuries: Acute vs. Chronic
| Condition Type | Common Examples | WSIB Claim Approach |
|---|---|---|
| Acute Trauma | Arterial Gas Embolism, Ruptured Eardrum | Treated as a standard accident. Immediate Form 6 required. |
| Decompression Sickness | The Bends, Neurological DCS | Requires dive logs and immediate hyperbaric medical reports. |
| Chronic Occupational Disease | Dysbaric Osteonecrosis, Long-term Hearing Loss | Requires proving prolonged exposure over years of employment. |
How Long Does the Process Take?
You strictly have 6 months from the date of an acute diving accident (or 6 months from the date a doctor diagnoses a chronic occupational disease) to file your Form 6 with the WSIB. Because DCS is a recognized medical emergency, initial treatment approvals usually happen within 24 to 48 hours. However, adjudicating a complex claim for long-term neurological damage or chronic bone disease can take 3 to 8 months, especially if an appeal is required.
Frequently Asked Questions (FAQ)
Does WSIB cover permanent damage from the bends?
Yes. If your diving injury results in a permanent impairment, such as chronic pain, nerve damage, or restricted mobility, you may be entitled to a Non-Economic Loss (NEL) award. This is a one-time lump sum payment compensating you for the permanent loss of bodily function.
What if I am an independent contractor, not an employee?
Many commercial divers operate as independent contractors. However, under Ontario law, if a company hired you and controlled your work environment (Schedule 1 or 2 employers), you may still be legally classified as a “worker” for WSIB purposes. A law firm can help prove your worker status to secure coverage.
Can I sue my employer instead of using WSIB?
Generally, no. The WSIB is a “no-fault” insurance system. In exchange for guaranteed benefits without having to prove employer negligence, workers give up their right to sue their employer in civil court. There are rare exceptions, such as if an unrelated third party caused the injury.
Will WSIB retrain me if I can never dive again?
Yes. If a severe barotrauma or DCS event permanently revokes your commercial diving medical clearance, WSIB provides Work Transition services to retrain you for a safe, land-based career while continuing to pay your Loss of Earnings benefits.
