Workplace accidents can be life-altering. If you’ve been injured on the job in Calgary or elsewhere in Alberta, you may be wondering: Can I sue my employer? What benefits am I entitled to? The answer depends largely on whether your employer is covered under Alberta’s Workers’ Compensation Board (WCB) system.

Can I Sue My Employer After a Workplace Injury in Alberta?
In Alberta, the Workers’ Compensation Act (WCA) governs workplace injuries. Most employers in Calgary and across the province fund this system to protect themselves from lawsuits. In return, injured workers are entitled to no-fault compensation, meaning you don’t need to prove your employer was negligent to receive benefits.
This system is often referred to as the “historic trade-off”—workers lost the right to sue their employers in exchange for timely, consistent compensation regardless of fault.
Who’s Covered?
Most employment types are covered under this scheme in Alberta, including:
- Full-time employees
- Part-time employees
- Temporary staff
- Casual workers
What Workplace Injury Compensation Is Available in Alberta?
If your injury is covered under Alberta’s Workers Compensation Board (WCB) program, you may be entitled to a broad range of injury compensation benefits, including:
- Wage replacement up to 90% of your net earnings
- Coverage for medical treatments including diagnostics, prescriptions, and physiotherapy
- Help with household tasks you’re unable to perform
- Personal care assistance for activities like food preparation, hygiene, or banking
- Home and vehicle modifications to accommodate your disability
- Travel and lodging reimbursement if you require medical treatment outside your area
- Return-to-work programs including modified duties and re-employment services
- Permanent impairment awards for lasting injuries
These benefits are designed to ease your recovery and support your return to work when possible.
How to File a WCB Claim in Alberta:
The process for filing a workplace injury claim involves multiple steps:
- Notify your employer of the injury as soon as possible.
- Employers must report the injury to WCB within 72 hours if the injury required more than basic first aid, caused missed work, or led to modified duties.
- Tell your doctor, physiotherapist, or chiropractor about your work-related injury—they must report it to WCB within 48 hours.
- You can also report the injury yourself directly to the WCB.
Once reported, the WCB-Alberta will coordinate medical care and wage replacement as needed. Read the full Worker Handbook here for detailed filing instructions.
Section 23 of the Workers’ Compensation Act: Understanding the Lawsuit Bar
Section 23 of the Workers’ Compensation Act is clear: if your injury occurred in a covered industry, you cannot sue your employer. Instead, your compensation comes through the WCB system.
Can I Sue After a Workplace Injury?
In specific circumstances, you may be able to sue a third party responsible for your injury. If your injury was caused by:
- Defective equipment
- A negligent contractor
Important limitation: However, even then, the WCB has the right to take control of the lawsuit and recover costs on your behalf.
Is My Industry Exempt from Worker Compensation?
Some Alberta industries are exempt from mandatory WCB coverage. To check whether your industry is exempt from the workers compensation scheme, refer to Alberta’s list of exempt industries.

Legal Case Study: Donnelly Estate and the Limits of Lawsuits
The Alberta court case Donnelly Estate v. Kal Tire and Bridgestone/Firestone Canada highlights how far-reaching the WCA’s protections for employers can be.
Case Background
In this case, Mr. Donnelly died in a car accident partly caused by faulty tire installation. His estate attempted to sue Kal Tire and the tire manufacturer. However, both companies were considered “employers” under the WCA, and the lawsuit was barred.
Court Ruling and Implications
The Alberta court reaffirmed that allowing the claim would undermine the foundation of the Workers Compensation system:
“Without such a bar, employers would have to contribute to an insurance scheme without receiving protection from lawsuits by injured employees… This argument must fail.” – Donnelly Estate v. Kal Tire and Bridgestone/Firestone Canada
This case illustrates that even claims seemingly unrelated to workplace conditions—like those involving third-party goods or services—may be barred under Alberta’s workers’ compensation laws.

Does WCB still pay 90% of net wages in 2026?
Yes. WCB Alberta continues to base wage replacement on 90% of your net employment earnings, calculated after income tax, CPP, and EI are deducted.
Can I work part-time while receiving WCB benefits?
In many cases, yes. WCB may support modified or graduated return-to-work arrangements, and your benefits may be adjusted based on any income you’re able to earn.
What happens if my employer disputes my claim?
Your employer can raise objections during the WCB review process, but the WCB makes the final determination on eligibility. You retain the right to appeal a decision you disagree with.
Do I need a lawyer to file a WCB claim?
Not to file the claim itself. However, legal guidance is often useful if your claim is denied, if you’re facing employer retaliation, or if a third-party lawsuit may apply to your situation.
