Can you work while on EI sickness benefits?

Yes, under certain circumstances. EI sickness benefits are paid when you are unable to work due to illness, injury, or quarantine. If your condition improves enough to allow part-time or reduced-capacity work before you are fully recovered, you can work while still on claim. The same Working While on Claim (WWC) rules apply: for every dollar earned, your EI benefit is reduced by $0.50, up to a 90% earnings threshold. Earnings above 90% of your weekly insurable earnings are deducted dollar-for-dollar. You must remain "incapable of working" to some degree — if you return to full-time work, you are expected to be fully recovered and would close your sickness claim.

How long can you receive EI sickness benefits in Canada?

EI sickness benefits provide up to 26 weeks of income replacement. This was extended from the previous 15-week maximum as of 2022. The 26 weeks covers serious illnesses and longer recovery periods. You may receive fewer weeks if you recover faster and return to work, or if you run out of the insurable hours in your benefit period. EI sickness benefits pay at 55% of your weekly insurable earnings, to a maximum of 55% of the annual insurable earnings ceiling. For 2025: maximum insurable earnings = $65,700, so maximum weekly EI = $668/week.

Does your employer have to accommodate a graduated return to work?

In Canada, employers with 15+ employees have a duty to accommodate employees to the point of undue hardship under human rights legislation (federal Canadian Human Rights Act and provincial equivalents). For a medical return to work, this typically means the employer must consider a graduated return-to-work (GRTW) schedule — starting with reduced hours and gradually increasing to full-time. The employer is not required to accommodate if it would cause "undue hardship" (extreme cost or fundamental operational disruption). If your employer refuses a reasonable GRTW plan, consult an employment lawyer or your provincial human rights commission. Your disability insurer (if you have long-term disability coverage) or Workers' Compensation Board (if work-related injury) may also be involved in coordinating the return.

What medical documentation is required for EI sickness benefits?

To receive EI sickness benefits, you must provide a medical certificate completed by a licensed medical practitioner (doctor, nurse practitioner, or dentist in some cases). The certificate: states that you are unable to work due to your medical condition; specifies the period of incapacity; is provided to Service Canada with your claim. Service Canada does not require the diagnosis itself — the certificate need only confirm incapacity. Your employer is typically not entitled to your diagnosis, only to confirmation that you are unable to work. The medical certificate is submitted when you apply for EI sickness benefits — Service Canada reviews and approves or denies based on the certificate.

Can EI sickness benefits be combined with long-term disability insurance?

EI sickness benefits are typically paid before long-term disability (LTD) insurance kicks in. LTD policies usually have a waiting period (commonly 90–180 days) and are designed to begin after short-term disability and EI benefits are exhausted. If you receive both EI and LTD simultaneously, many LTD policies include a direct offset — meaning LTD pays the difference between your EI sickness benefit and your LTD benefit amount, so the total does not exceed your policy's replacement income level. Read your LTD policy carefully. If you receive more than your policy allows, you may be required to repay the overpayment to the insurer.

What happens to EI sickness benefits if you recover before the 26 weeks end?

If you recover from your illness before your 26-week EI sickness entitlement is exhausted, you stop receiving benefits when you return to work full-time. Your remaining weeks are not "banked" for later use. However, if you have a relapse of the same condition or are unable to find work after recovery, you can request to convert unused sickness weeks to regular EI weeks (if you are also unemployed). This depends on your specific claim structure and requires re-application. Inform Service Canada as soon as you return to work — overpayments for weeks when you were able to work must be repaid.

Can you receive EI sickness benefits and CPP Disability at the same time?

Not simultaneously for the same period. EI sickness benefits are a short-term benefit (up to 26 weeks). CPP Disability is a long-term benefit for people with severe and prolonged disabilities. If your condition is serious and expected to last more than a year, you can apply for CPP-D while on EI sickness benefits — but CPP-D takes months to process and includes a 4-month waiting period after the disability onset date. Any CPP-D award received for a period that overlaps with your EI sickness claim results in an overpayment of EI that must be repaid. Coordinate the application timing carefully; an experienced social worker or benefits specialist can help.

Working While on EI Sick Leave Canada: Returning to Work and Partial Capacity Rules

EI sickness benefits give you up to 26 weeks to recover from illness or injury. Working in a partial or reduced capacity during recovery is allowed under the Working While on Claim rules — provided you meet reporting requirements and are not considered fully recovered.

EI sickness benefits: the basics

Feature	Detail
Weekly rate	55% of weekly insurable earnings
Maximum weekly benefit (2025)	~$668/week
Maximum duration	26 weeks
Waiting period	1-week waiting period before benefits begin
Medical requirement	Medical certificate from licensed practitioner
CPP/EI deductions	EI premiums not deducted from sickness benefits

To qualify: you must have accumulated 600 insurable hours in the past 52 weeks (or since last claim), and be incapable of working due to illness, injury, or quarantine.

Working in partial capacity during sickness EI

If you are recovering and your doctor approves reduced or modified duties before full recovery, you can work part-time while on EI sickness benefits.

How the Working While on Claim rules apply:

Same as regular EI:

Earnings below 90% of weekly insurable earnings → benefit reduced by $0.50 per dollar earned
Earnings above 90% threshold → excess deducted dollar-for-dollar

Key condition: You must remain partially incapacitated. If you are capable of full-time work, you should close your sickness claim.

Example: Partial return

Pre-illness insurable earnings: $1,000/week
EI sickness benefit (55%): $550/week
90% threshold: $900/week
Part-time return earns $400/week

Earned	EI reduction	EI paid	Total
$400	$200	$350	$750

Without part-time work, total would have been $550.

Graduated return to work (GRTW)

A graduated return to work is a structured plan involving you, your doctor, and your employer to incrementally increase your working hours back to full-time.

Typical GRTW schedule

Week	Hours per day	Days per week	Notes
1–2	3–4 hours	3 days	Initial assessment
3–4	4–5 hours	4 days	Increased capacity
5–6	Full hours	5 days	Return to full duties

During GRTW

You may still receive EI sickness benefits for weeks you are not working full-time, subject to WWC rules
Report all earnings to Service Canada biweekly
When your GRTW completes and you resume full-time hours: close your EI sickness claim by stopping to file biweekly reports

Employer duty to accommodate

Under human rights legislation, employers must offer accommodation (including GRTW) to the point of undue hardship. A reasonable employer should:

Accept a doctor-supported GRTW plan
Not require you to return at full capacity before your medical certificate allows
Maintain your original position or a comparable one

If your employer refuses reasonable accommodation, contact:

Your provincial human rights commission
Your union (if applicable)
An employment lawyer

Relapse and re-opening a sickness claim

If you return to work, close your EI sickness claim, and then experience a relapse of the same or a different condition:

You can re-apply for EI sickness benefits
The original illness vs. new condition matters: if it is a relapse of the same illness within a reasonable timeframe, Service Canada may apply the original claim’s insurable hours threshold rather than requiring a full new 600-hour accumulation
You need a new medical certificate for the new/relapsed illness period
Maximum total weeks per qualifying period: 26 weeks

Connecting sickness EI with other benefits

Short-term disability (employer plan)

Many employers have a group short-term disability (STD) plan paying 75–100% of salary for the first weeks of illness. Coordination: STD typically pays for weeks 1–13 (or as specified) and transfers to EI sickness benefits after STD is exhausted (using the EI waiting period waiver for STD-compliant plans). Check your group benefit plan for details.

Long-term disability (LTD)

LTD begins after the STD/EI sickness period ends (typically at day 90, 120, or 180 of disability). If you remain unable to work after 26 weeks of EI sickness benefits, LTD should be in payment. LTD pays until age 65 or recovery, whichever comes first. LTD is not administered by Service Canada — apply through your employer’s group insurer or a private policy.

CPP Disability (CPP-D)

For severe and prolonged conditions (expected to last over 12 months):

Apply for CPP-D while on STD/EI sickness benefits
CPP-D has a 4-month waiting period from disability onset
CPP-D approval takes several months — apply early
Overlap of CPP-D and EI results in overpayment — coordinate timing carefully

Reporting while on EI sickness

Same biweekly report requirement as all EI claims:

Log into MSCA (My Service Canada Account)
Complete biweekly questions including any earnings
Confirm you remain unable to work full-time due to medical condition
Report gross earnings from any part-time work performed

If you are fully recovered and return to work mid-claim: File your final biweekly report, indicate you have returned to work full-time, and close your claim. Do not continue filing reports once you are fully capable of work — overpayments will result.
