Should You Use Employer Sick Days or File a WSIB Claim in Ontario?

💡

Never use your banked sick days or short-term disability for a workplace injury in Ontario. Accepting sick pay instead of filing a formal Workplace Safety and Insurance Board (WSIB) claim can permanently jeopardize your right to specialized medical coverage, Loss of Earnings (LOE) benefits, and vital job protection.

When you get hurt on the job, your employer’s first reaction might be to offer you paid sick days or tell you to apply for the company’s short-term disability plan. While this may seem like a generous offer to keep your income flowing without paperwork, it is often a strategic trap. In Ontario, employers pay premiums to the WSIB based on their safety records. By convincing you to use sick leave, they keep an accident off their official record, avoiding premium hikes while shifting the burden entirely onto you. Whether you work in a corporate office in Mississauga, a retail centre in London, or a hospital in Ottawa, the rules are the same: workplace injuries belong to the WSIB.

Using your personal sick bank for a work-related injury strips you of the massive legal protections designed for injured workers. 💼 If your injury requires surgery a year later or results in chronic pain, your sick days will run out, leaving you with zero income and no active WSIB claim to fall back on. It is generally advised to consult with a local labour lawyer if your employer is pressuring you to bypass the provincial workers’ compensation system.

Step-by-Step Process in Ontario

Transitioning from a confusing conversation with Human Resources to a formalized legal claim requires decisive action. You must protect your long-term health and financial stability.

Step 1: Recognize Claim Suppression Tactics

The first step is identifying what is happening. If a manager suggests you “take a few paid days off to rest” and asks you not to fill out an incident report, this is a red flag. Ontario law strictly prohibits employers from discouraging workers from claiming WSIB benefits. You must mentally separate your earned sick leave (which is for the flu or personal illness) from statutory compensation for a workplace hazard.

Step 2: Clearly Refuse the Sick Leave Offer

You must communicate your refusal clearly and preferably in writing. 📧 Send an email to your supervisor or HR department stating, “Because this injury occurred while performing my work duties, I will be reporting this to the WSIB as required by law, rather than using my personal sick bank.” This creates a vital paper trail showing that you attempted to follow the proper legal channels immediately.

Step 3: Seek Proper Medical Documentation (Form 8)

Go to a doctor immediately. It is absolutely critical that you tell the emergency room staff or your physician that you were injured at work. Do not let the doctor bill your standard OHIP card for a personal ailment. The physician must complete a WSIB Form 8 (Health Professional’s Report) and submit it directly to the board. This medical evidence is the foundation of your claim.

Step 4: Submit Your Worker’s Report (Form 6)

Do not wait for your employer to act. 📑 Go online to the WSIB portal and submit your Form 6 (Worker’s Report of Injury/Disease). You must detail exactly how the injury happened and the symptoms you are experiencing. Even if you only missed one day of work, having an approved claim on file protects you if the injury unexpectedly worsens in the future.

Step 5: Address Payroll Adjustments

If your employer already deducted sick days from your bank before you could stop them, you can seek to have this corrected. Once your WSIB claim is approved, the WSIB pays you Loss of Earnings (LOE) benefits (or reimburses your employer if they advanced the funds). While the WSIB lacks the statutory jurisdiction to directly manage or order changes to a private employer’s internal HR leave bank, the restoration of your sick days will be governed by your employment contract, collective agreement, or company policies after the WSIB approval is finalized.

Comparing WSIB vs. Employer Sick Days

FeatureWSIB ClaimEmployer Sick Days
Income ReplacementUp to 85% of net earnings (LOE benefits).100% of wages, but drains your personal bank.
Duration of CoverageCan last until age 65 if permanently disabled.Runs out quickly (often 5 to 15 days total).
Medical Costs Covered?Yes (Physio, meds, specialized equipment).No, you must pay or use standard private benefits.
Job ProtectionStrong legal duty to accommodate and re-employ.Standard employment standards apply, less protection.
Future RecurrenceFile can be reopened years later if pain returns.Once used, you have no legal safety net for recurrences.

How Much Does it Cost in Ontario?

Filing a proper claim protects your wallet long-term.

  • Filing Fees: There is absolutely no cost to file a WSIB claim.
  • Medical Treatment: WSIB covers approved treatments (like chiropractic care or physical therapy) entirely. Using sick days forces you to pay out-of-pocket or exhaust your personal health benefits.
  • Legal Assistance: If your employer fights the claim because you refused sick days, a WSIB law firm typically charges a contingency fee or hourly rates between $300 and $600 CAD.

How Long Does the Process Take?

Using sick days is instantaneous, but filing WSIB takes a bit of patience. You have 6 months to file your Form 6. Once submitted, a straightforward WSIB claim (like a broken arm with clear evidence) is often approved within 2 to 4 weeks. More complex claims, such as repetitive strain injuries, may take several months to adjudicate. However, once approved, your Loss of Earnings benefits are paid retroactively to the date of the accident.

Frequently Asked Questions (FAQ)

What if I already agreed to use my sick days? Can I still file for WSIB?

Yes. Even if you initially agreed to use sick days under pressure, you still have the legal right to file a WSIB claim within the 6-month deadline. You can ask the WSIB to correct the record and have your employer restore your sick bank.

Will filing a claim instead of using sick leave make my employer angry?

It might, but your legal and physical protection is more important. It is against the law for an employer to punish or fire you for exercising your right to claim WSIB benefits in Ontario.

Can I claim both WSIB and my sick pay at the same time?

No, you cannot double-dip. However, some employers offer ‘top-up’ programs where WSIB pays 85% of your net earnings, and the employer uses a fraction of a sick day to top you up to 100%. This must be formally arranged through the WSIB.

What is a Non-Economic Loss (NEL) award?

If your injury results in a permanent impairment, the WSIB may pay you a lump sum NEL award for your pain and suffering. If you never file a WSIB claim and just use sick days, you forfeit your right to ever receive this financial compensation.

Does my employer have to pay for my ambulance if I get hurt at work?

Yes. Under Ontario law, the employer is responsible for the cost of your transportation from the workplace to the hospital or doctor’s office on the day of the injury. This is independent of your sick day bank.
