Workers Compensation in Canada: Overview
Workers compensation (called WSIB in Ontario, WorkSafeBC in BC, WCB-Alberta in Alberta, the CNESST in Quebec, and a workers compensation board in each other province and territory) replaces part of your income when a work-related injury or illness keeps you from working. The rules differ by province, but the system works the same way in outline everywhere. This page covers how much you can earn while receiving benefits; the rest of your rights at work are in the workplace rights and employee benefits guide.
How workers’ compensation benefits work
- It’s insurance your employer pays for, and fault doesn’t matter. Each provincial board is funded by employer premiums; WSIB, for example, describes itself as providing “no-fault collective liability insurance” funded by Ontario businesses. In exchange, a covered worker generally can’t sue the employer over the injury.
- Most, but not all, workers are covered. Coverage is compulsory for most industries, but each province exempts some kinds of work and lets some business owners opt in, so the first question is whether your employer is registered with the board.
- Benefits replace a share of lost pay. In Ontario, the loss-of-earnings benefit for injuries on or after January 1, 1998 is 85% of take-home pay, up to an annual maximum; other boards use their own percentage of net or gross earnings and their own maximum (see the table below). Health care costs from the injury are covered too.
- When payments start and stop. WSIB’s benefit normally starts the day after the injury, when you begin to miss work, with the employer paying your full shift on the day itself; it continues until the injury no longer affects your ability to do your pre-injury work, you’re no longer losing pay, or you reach age 65 (two years after the injury if you were 63 or older when it happened).
- Reporting and claiming. You report the injury to your employer right away and get first aid or medical care; the employer reports it to the board, and you file your own claim with the board. Each board sets its own deadlines for reporting and claiming.
- Return to work is part of the claim. While receiving benefits you’re expected to take part in recovery and a return to suitable work, which is where the earnings rules on this page come in.
Time off for illness or injury that isn’t work-related is covered by sick leave and EI sickness benefits instead: see sick leave rights by province and EI sickness benefits. Long-term illness outside work may also be covered by disability insurance, and tax on long-term disability benefits works differently from workers’ comp. If your employer cuts your hours rather than your job, see reduced hours.
Can You Work While on Workers Compensation?
| Situation | Working allowed? |
|---|---|
| Total temporary disability | Generally no, or very limited |
| Partial/modified capacity | Yes: return-to-work programs are standard |
| Permanent partial disability | Often yes, with earnings offset |
| Doing unauthorized outside work | No: and must be disclosed |
Workers compensation boards actively promote return-to-work (RTW) programs, so limited or modified work is expected as part of recovery, not penalized by default.
How Earnings Affect Benefits: Province-Level Summary
Workers compensation benefit calculations differ by province. The general principle in most provinces:
Your loss-of-earnings benefit = Pre-injury earnings − Current earnings ability
If you earn $0, you receive close to full income replacement. If you earn part of your pre-injury wage, benefits make up the gap: to a maximum covered wage cap.
Ontario (WSIB): Loss of Earnings (LOE) Benefit
| Item | Detail |
|---|---|
| Base rate | 85% of net pre-injury earnings |
| If working modified duties | Benefit adjusted to top up to 85% of pre-injury earnings |
| No-earnings situation | Receive full 85% of pre-injury net income |
| Maximum insurable earnings | An annual maximum, adjusted each year |
| Duration | Until the injury no longer affects your pre-injury work or you’re no longer losing pay, or to age 65 (two years after the injury if you were 63 or older) |
Example: If your take-home pay was $1,000 a week before the injury and modified work now pays $600 a week take-home, the loss of earnings is $400 a week. At WSIB’s 85% rate, the benefit is about $340 a week, on top of the modified-work pay.
British Columbia (WorkSafeBC)
| Item | Detail |
|---|---|
| Base rate | 90% of net earnings up to maximum |
| If earning during claim | Benefits reduced by earnings received |
| Vocational rehabilitation earnings | May have separate exemption rules |
| Maximum annual earnings | Set and indexed each year by WorkSafeBC |
Alberta (WCB-Alberta)
| Item | Detail |
|---|---|
| Base rate | 90% of net earnings |
| Light duty wage | If earning less than gross pre-injury, WCB tops up to 90% of original net |
| Maximum insured earnings | Set and indexed each year by WCB-Alberta |
Doing Any Work: Disclosure Is Essential
Whether you are:
- Helping a family member with their business
- Doing casual or cash work for a neighbour
- Running any self-employment activities
You must disclose all work activity to your compensation board. Boards investigate undisclosed work through:
- Employer payroll cross-checks
- Social media and in-person surveillance (common in contested claims)
- CRA income data sharing
- Tip lines
Consequences of undisclosed work include benefit repayment (sometimes retroactive to the date of undisclosed activity), permanent cessation of benefits, criminal fraud charges in serious cases, and lifetime dossier flags.
Return to Work Programs
Most provinces have formal RTW frameworks:
| RTW stage | Description |
|---|---|
| Modified duties | Same employer, reduced hours or different tasks |
| Graduated return | Increasing hours/duties over weeks |
| Retraining/vocational rehabilitation | If original job is not possible: boards often cover |
| New employer placement | Board helps arrange alternate employment |
If your employer offers suitable modified work and you refuse without a medical reason, your benefits may be reduced or suspended.
Workers Compensation and Taxes
This is commonly misunderstood:
| Tax rule | Detail |
|---|---|
| Workers comp benefits taxable? | No: tax-exempt |
| Appear on T4? | No |
| Reported anywhere on tax return? | Yes: added to total income at Line 14400, then deducted at Line 25000 to get from net income to taxable income |
| Count toward net income (Line 23600)? | Yes: the Line 25000 deduction happens after net income is calculated, so it still counts toward net income |
| Count toward OAS clawback? | Yes: OAS Recovery Tax is based on net income, which includes workers’ comp benefits |
| Count toward RRSP contribution room (earned income)? | No: workers comp is not earned income for RRSP purposes |
| Count toward EI clawback (Social Benefits Repayment)? | Yes: also based on net income |
| Affect GIS calculation? | No: GIS is a documented exception; Service Canada specifically excludes workers’ comp from the GIS income test even though it remains part of net income for other purposes |
Workers’ compensation benefits are never taxed directly: the Line 25000 deduction removes them from taxable income (Line 26000), which is what your actual tax bill is calculated on. But because that deduction happens after net income (Line 23600) is already calculated, workers’ comp still counts toward most net-income-based programs, including the OAS clawback, GST/HST credit, and Canada Child Benefit. GIS is the notable exception, since Service Canada excludes it specifically for GIS purposes.
Workers Comp vs. Long-Term Disability Insurance
Workers comp only applies to workplace injuries and occupational illness. If your condition is not work-related, you may need LTD insurance instead.
| Feature | Workers Compensation | LTD Insurance |
|---|---|---|
| Work-related injury required | Yes | No |
| Coverage funded by | Employer premiums (no worker cost) | Employer, employee, or personal premium |
| Earnings rules | Yes: offset against benefits | Depends on policy |
| Tax treatment | Tax-free benefits | Depends on who pays premium |
| Duration | Potentially lifetime | Typically to age 65 |
Workers compensation benefit comparison by province
| Province | Agency | Wage replacement rate |
|---|---|---|
| Ontario | WSIB | 85% of net pre-injury earnings |
| BC | WorkSafeBC | 90% of net earnings |
| Alberta | WCB-Alberta | 90% of net earnings |
| Quebec | CNESST | 90% of net income |
| Saskatchewan | WCB | 90% of net earnings |

| Nova Scotia | WCB NS | 75% of net earnings |
| New Brunswick | WorkSafeNB | 85% of net earnings |
| Federal government employees (ESDC) | GECA | Paid at the rate of the province where the employee usually works |
Each board also caps the earnings it covers at a maximum it adjusts every year; the current figure is on your provincial board’s website.
Frequently asked questions
Is workers compensation taxable in Canada? No. Workers compensation payments are not taxable under the Income Tax Act. However, they are reported on a T5007 slip and must be entered on your T1 return (line 14400): they are then deducted at line 25000. The income is included in calculations for income-tested benefits (e.g., Canada Groceries and Essentials Benefit, CCB) but is not directly taxed.
Can I get fired while on workers compensation in Canada? You cannot be dismissed specifically because you filed a WCB claim or are on workers compensation: this is considered retaliatory and is prohibited in every province. However, employers can still terminate for unrelated reasons (layoff, business closure). If you believe termination was linked to your claim, file a complaint with your provincial workers compensation board.
What if my WCB claim is denied? All provinces have an appeals process. In Ontario, you can appeal to the Workplace Safety and Insurance Appeals Tribunal (WSIAT). In BC, the Workers Compensation Appeal Tribunal (WCAT). Most provinces also have worker advocate services that provide free help navigating appeals: search “[province] workers compensation legal clinic” or contact your union rep.
