WSIB Hearing Loss Claims in Ontario

If years of loud work have left you struggling to hear conversations, missing words on the phone, or dealing with constant ringing in your ears, you may be wondering whether WSIB hearing loss claims in Ontario cover your situation. Work-related hearing loss can be confusing because it often builds slowly. Many workers do not connect it to their job until an audiogram shows permanent damage.

Noise-induced hearing loss can develop slowly after years of loud work.

This guide explains how occupational hearing loss claims usually work, what evidence WSIB commonly asks for, what benefits may be available, and what steps to take if WSIB denies your claim or limits your benefits. It is written for Ontario workers who need plain-language information before deciding what to do next.

What counts as a WSIB hearing loss claim?

A WSIB hearing loss claim is a workplace insurance claim for hearing damage connected to work in Ontario. WSIB recognizes more than one type of work-related hearing loss. The two main categories are noise-induced hearing loss and traumatic hearing loss.

Noise-induced hearing loss

Noise-induced hearing loss is usually gradual. It can happen after repeated exposure to loud tools, machinery, vehicles, equipment, or other workplace noise over a period of years. Workers in construction, manufacturing, mining, transportation, warehouses, public works, auto repair, and similar environments may face this risk.

WSIB describes noise-induced hearing loss as permanent hearing loss in both ears that develops over time because of prolonged exposure to excessive noise levels. Its published criteria include continuous exposure to 90 decibels of noise for eight hours per day for at least five years, hearing loss in each ear, and an audiogram pattern consistent with noise-induced sensorineural hearing loss.

Traumatic hearing loss

Traumatic hearing loss is different. It happens suddenly because of a specific event, such as an explosion, a sudden noise blast, a direct injury to the ear, a serious head injury, or exposure to an ototoxic chemical or substance at work. If your hearing changed after one clear workplace incident, WSIB may treat the claim differently than a gradual noise-induced claim.

Tinnitus

Tinnitus means sound in the ear or head when there is no outside sound. Workers often describe it as ringing, buzzing, hissing, or humming. WSIB says tinnitus can be related to noise-induced or traumatic hearing loss, and tinnitus claims may be eligible for health care benefits. If ringing in your ears is one of your main symptoms, tell your audiologist and include it in your claim documents.

What benefits can WSIB cover for work-related hearing loss?

If WSIB accepts your hearing loss claim, benefits may include hearing devices and hearing health services. WSIB states that it covers the cost of hearing devices and hearing health services for people with approved traumatic hearing loss claims and noise-induced hearing loss claims.

Depending on the decision and your medical needs, an accepted claim may involve:

• Hearing aids or other approved hearing devices
• Audiology services and hearing assessments
• Repairs, maintenance, or replacement of approved devices where covered
• Related health care services through WSIB's hearing services program
• Possible benefits for permanent impairment, depending on the facts of the claim

One important point: a WSIB claim number is not the same as approval. WSIB says you must have a decision letter showing the claim and health care benefits are approved before a hearing health care provider can prescribe and fit hearing aids under the accepted claim. For a wider look at benefit types, see how much WSIB pays in Ontario.

What evidence matters most in a hearing loss claim?

Hearing loss claims often turn on evidence. Because noise-induced hearing loss develops slowly, WSIB may look closely at your work history, the kind of noise you were exposed to, your medical records, and whether your audiogram matches the pattern WSIB expects to see.

1. Audiogram and hearing assessment

An audiogram is one of the most important documents in a hearing loss claim. It measures your hearing levels at different frequencies. WSIB asks for an audiogram when workers submit noise-induced hearing loss claims. A full assessment may also include clinic information, the audiologist's findings, and notes about tinnitus or other symptoms.

If you have older hearing tests from work, a union clinic, a doctor, or a previous employer, gather those too. Older tests can help show when your hearing started to change and whether it worsened over time.

2. Proof of employment

WSIB asks workers to provide proof of employment for each relevant employer. This can matter when the exposure happened years ago or across more than one job. WSIB says proof of employment can include pay stubs, records of employment, pension statements, award recognitions, mining cards, co-worker vouchers, and previous claim documents.

Do not assume you have no proof just because a workplace closed or you no longer have old pay stubs. Make a list of possible records and people who can confirm where you worked.

3. Noise exposure history

Your claim should explain the noise you faced at work. WSIB's online noise-induced hearing loss claim form asks for the names and addresses of employers, the amount of time spent at each employer, and a list of tools or equipment that contributed to the hearing loss.

Useful details include:

• Job titles and departments
• Dates you worked in noisy areas
• Machines, tools, vehicles, alarms, presses, saws, drills, compressors, or other noise sources
• How many hours per day or week you were exposed
• Whether hearing protection was provided and whether it was practical to use
• Names of co-workers, supervisors, or union representatives who can confirm the noise conditions

4. Medical and appointment records

WSIB may ask for dates and locations of hearing-loss-related appointments, including visits with audiologists and ear, nose, and throat specialists. Keep copies of reports, referrals, prescriptions, and letters. If another condition may affect your hearing, ask your health care provider to explain what is work-related and what is not.

How do you start a WSIB hearing loss claim in Ontario?

For gradual noise-induced hearing loss, WSIB provides an online claim process. WSIB says the form takes about 45 minutes to complete and asks for proof of employment, an audiogram, work history, equipment and tool details, health care appointment information, and basic personal information.

If you do not have everything ready, WSIB says you can start the online form with the information you have and will have 30 days from the date you start the form to gather the rest of your documents. You can also submit a paper Workers' Report of Occupational Noise-Induced Hearing Loss by fax or mail, or call WSIB for help.

Before you start, consider this checklist:

• Book or gather a recent audiogram.
• Write down every noisy workplace, even if it was years ago.
• Collect proof of employment for each workplace.
• List the tools, machines, vehicles, or processes that made the noise.
• Write down when symptoms started and how they affect your daily life.
• Keep a copy of everything you send to WSIB.

If you already have a denial letter or you are unsure how to present your work history, start the ClaimIt intake form to connect with a WSIB representative who can review your next steps.

Why are some WSIB hearing loss claims denied?

A denial does not always mean your hearing loss is not real. It means WSIB was not satisfied that the claim met the legal and policy requirements based on the information it had. Hearing loss claims can be denied or limited for several reasons. For broader denial patterns, see our guide to the top reasons WSIB claims get denied in Ontario.

Common issue	Why it matters	What may help
Missing or weak work history	WSIB may not see enough evidence of noisy employment.	Employment records, co-worker statements, union records, old job descriptions, or other proof.
Audiogram does not match WSIB's expected pattern	WSIB may question whether the loss is noise-induced.	Audiologist or specialist clarification, older audiograms, or medical opinion.
Exposure below WSIB criteria	WSIB may decide the noise level or duration was not enough.	More detailed exposure evidence, equipment details, workplace noise records, or witness evidence.
Other possible causes	WSIB may point to age, medical conditions, hobbies, or non-work noise.	Medical evidence explaining the likely cause and separating work from non-work factors.
Late or incomplete documents	Important facts may not be in the file when the decision is made.	Submit missing records quickly and ask for reconsideration where appropriate.

What should you do if WSIB denies or limits your hearing loss benefits?

Start with the decision letter. Read what WSIB accepted, what it denied, and why. If you are dealing with a denied claim more generally, our guide on what to do after a WSIB claim denial can help you organize your next steps. The reasons in that letter tell you what evidence may be missing. Then mark the deadline. WSIB says there are time limits for objecting to decisions. You generally have up to six months to object to most claim decisions, but only up to 30 days for return-to-work and re-employment decisions. Always follow the deadline in your own decision letter.

1. Ask the decision-maker to reconsider. WSIB says that if you disagree with a decision, you can ask the decision-maker to reconsider it. This is your chance to explain why you disagree and provide additional information. For a hearing loss claim, that could mean a clearer audiology report, proof of employment, a more detailed noise exposure history, or medical evidence about tinnitus.
2. File an Intent to Object if you still disagree. If the decision does not change, WSIB says you can object by submitting an Intent to Object form or a letter of objection. Be specific about the issue you disagree with. For example, you may disagree with a denial of entitlement, the level of hearing loss accepted, the refusal to cover hearing aids, or the date WSIB used.
3. Prepare the appeal record. An appeal is not just about telling WSIB you disagree. It is about showing why the decision should change. That usually means connecting the evidence to the issue under appeal. In a hearing loss case, the strongest appeal submissions often explain the work exposure history, the medical testing, the policy criteria, and any errors in the decision.
4. Consider whether professional help makes sense. You can handle parts of a claim yourself, especially when you are still gathering basic records. But professional help may be useful if WSIB denies the claim, if there are multiple noisy employers, if the audiogram is disputed, if tinnitus is not properly addressed, or if important benefits are being limited. You can also learn how free WSIB appeal consultations work before choosing who to contact.

Frequently asked questions about WSIB hearing loss claims

Can I make a WSIB claim for hearing loss years after the noisy work?

Many noise-induced hearing loss claims involve exposure that happened over a long period, sometimes with older employers. The key issue is whether you can show work-related exposure and medical evidence connecting the hearing loss to that exposure. Gather employment proof, old audiograms, and details about the noisy work.

Does WSIB cover hearing aids?

WSIB says it covers hearing devices and hearing health services for people with approved traumatic hearing loss claims and approved noise-induced hearing loss claims. You usually need an approval decision before hearing aids are prescribed and fitted through the WSIB claim.

What if my hearing loss was sudden after an explosion or accident?

Sudden hearing loss may be treated as traumatic hearing loss rather than gradual noise-induced hearing loss. WSIB lists acoustic trauma, direct ear trauma, serious head injury, and exposure to certain toxic substances as examples. Report the incident and get medical testing as soon as possible.

Can tinnitus be part of a WSIB claim?

Yes. WSIB says tinnitus can be related to noise-induced or traumatic hearing loss, and claims for tinnitus may be eligible for health care benefits. Make sure your health care provider documents the ringing, buzzing, hissing, or other symptoms you experience.

Do I need a lawyer for a WSIB hearing loss claim?

Not every claim needs a lawyer or paralegal. But if your claim is denied, your benefits are limited, your deadline is close, or WSIB says your evidence does not meet its criteria, a licensed WSIB representative may help you understand your options and prepare a stronger response.
