Can you sue for a workplace injury instead of taking WSIB in Ontario?

In Ontario, you cannot sue your own employer for a workplace injury if your job is covered by the WSIB. However, if your injury was caused by a negligent third party (like an external contractor or another driver), you may file an Election to sue them instead of taking WSIB benefits.

Getting injured on the job in Vaughan can completely derail your financial stability and physical well-being. The Workplace Safety and Insurance Board (WSIB) provides a no-fault insurance system for most workers in Ontario.

While WSIB is helpful, it only covers a percentage of your lost wages and does not offer compensation for pain and suffering. 📍 Many injured workers wonder if they can bypass the board and file a civil lawsuit (tort claim) to recover the full extent of their damages.

Step-by-Step Process: Choosing Between WSIB and a Lawsuit

If you work in one of Vaughan’s busy industrial sectors, like Concord or the Highway 400 corridor, understanding your options is critical. Here is how you determine the right path for your specific workplace injury.

Step 1: Report the Injury Immediately

Regardless of whether you plan to sue or claim benefits, you must notify your employer right away. 📞 Your employer is legally obligated to submit a Form 7 to the WSIB within three days of learning about a workplace injury that requires medical care.

Step 2: Determine if a Third Party is Liable

You generally cannot sue your boss or a co-worker. However, if a delivery driver from another company rear-ended your work vehicle, or a defective machine manufactured by an external corporation injured you, a third-party lawsuit may be possible.

Step 3: Consult a Personal Injury Law Firm

Before making any official decisions, speak with a qualified personal injury lawyer in Vaughan. 💼 They will evaluate your case to see if a tort claim would likely yield a higher financial recovery than standard WSIB benefits.

Step 4: File the Worker’s Election Form

If you are eligible and choose to sue the third party, you must submit an Election form to the WSIB. Typically, you have three months from the date of the accident to make this decision. Once you elect to sue, your tort claim will proceed through the Superior Court of Justice.

How Much Does it Cost in Ontario?

The financial implications of your choice are significant. 💵 WSIB benefits are free to claim, but they cap your income replacement and offer zero pain and suffering damages.

FactorWSIB Claim SystemCivil Lawsuit (Tort Claim)
Income ReplacementUp to 85% of your net earnings (subject to a maximum cap)Potential to recover 100% of past and future lost income
Pain and SufferingNot available (except for limited Non-Economic Loss awards)Available and can be substantial depending on the injury
Upfront Legal Costs$0$0 upfront (Lawyers use contingency fees of ~30%)
Risk LevelLow (No-fault system, guaranteed approval if eligible)Higher (You must prove the third party was negligent)

It is important to remember that if you lose your civil lawsuit, you cannot go back and claim WSIB benefits later. This makes the initial consultation with legal counsel absolutely vital.

How Long Does the Process Take?

Timeframes vary drastically between the two systems. ⌛ WSIB benefits can begin flowing within a few weeks of your injury being reported and approved. In contrast, a civil lawsuit in Ontario is a marathon. Depending on court backlogs in the York Region, a tort claim can take anywhere from 2 to 4 years to reach a settlement or trial verdict.

Frequently Asked Questions (FAQ)

Can I claim WSIB and sue the third party at the same time?

No. Under Ontario law, you must make a strict election. You can either claim WSIB benefits or sue the negligent third party, but you cannot “double dip” and do both simultaneously.

What happens if my employer does not have WSIB coverage?

Certain industries, like banking or independent contracting, do not require mandatory WSIB coverage. If your employer is uninsured by WSIB, you may have the right to sue them directly for negligence.

Can I change my mind after choosing WSIB?

If you initially applied for WSIB but later discover a third party was at fault, you can apply to “de-elect” WSIB. However, you must repay any benefits you received before proceeding with your lawsuit.

What is WSIB subrogation?

If you take WSIB benefits and a third party was responsible, WSIB has the right to step into your shoes (subrogation) and sue the third party themselves to recover the money they paid you.
