Medical Certificate Requirements

Service Canada requires a medical certificate (form or equivalent) confirming:

1. You are unable to work due to illness, injury, or quarantine
2. The date your inability to work began
3. The expected duration of your absence (or "unknown/ongoing")
4. That you are under the care of a medical practitioner
5. The practitioner's credentials, signature, and contact information

Who can sign the medical certificate:

Physician (MD), CPSO-registered in Ontario

Nurse Practitioner (NP), CNO-registered

Specialist physician

Psychologist (for mental health claims)

Midwife (for pregnancy-related conditions)

What the certificate does NOT need to include:

Specific diagnosis (only functional limitations)

Detailed treatment plan

Prognosis beyond expected duration

The OHIP Factor: Ontario's Unique Situation

Ontario's OHIP coverage creates a unique cost dynamic:

| Component | OHIP Covered? | Out-of-Pocket Cost |
|-----------|---------------|-------------------|
| Physician visit (assessment) | Yes | $0 |
| Medical certificate (document) | No (uninsured service) | $20-$40 |
| Follow-up visits | Yes | $0 |
| Specialist referral | Yes | $0 |
| Lab tests/imaging | Yes | $0 |

Key insight: The visit is free, but the certificate itself is not OHIP-covered. This is an "uninsured service" that physicians can charge for. Some physicians waive the fee for EI certificates, always ask.

Eligibility in Ontario: Detailed Requirements

To qualify for EI sickness benefits in Ontario, you must meet ALL of these criteria:

1. 600 insurable hours in the past 52 weeks (or since last EI claim)
2. Unable to work due to sickness, injury, or quarantine
3. Medical certificate from a qualified practitioner
4. 40%+ reduction in earnings due to the condition
5. Employed in insurable employment (not self-employed unless opted in)
6. Applied within 4 weeks of your last day worked (can be backdated up to 4 weeks)

Common disqualifiers in Ontario:

Self-employed without EI opt-in (Uber, DoorDash, freelancers)

Insufficient hours (common for part-time workers)

Already receiving WSIB benefits for the same condition

Already receiving employer-paid STD/LTD benefits

Voluntarily left employment before becoming ill

Ontario-Specific Considerations by Sector

Auto workers (Windsor, Oshawa, Brampton):

Collective agreements may provide sick leave pay that must be exhausted first

Unifor members should check their specific local agreement

Plant shutdowns + illness = may qualify for both regular and sickness EI (different conditions)

SUB (Supplemental Unemployment Benefits) plans may top up EI to 95% of earnings

Gig economy workers (Toronto, Ottawa, GTA):

Uber, DoorDash, Instacart, Skip drivers are typically NOT in insurable employment

Unless you have opted into EI for self-employed (must register 12+ months before claiming)

Check your employment status carefully, some "gig" workers are actually employees

Misclassification may entitle you to EI (file a ruling request with CRA)

Public sector workers (Ottawa, Toronto, Kingston):

Many Ontario public sector employees have generous sick leave banks (6-18 days)

Must typically exhaust employer sick leave before EI sickness kicks in

OPSEU, CUPE, ONA members should check collective agreements for coordination

Some agreements have SUB plans that top up EI benefits

Construction workers (province-wide):

Seasonal layoffs + illness can create complex EI situations

May qualify for regular EI AND sickness EI (different qualifying conditions)

Hours from multiple employers count toward the 600-hour threshold

LIUNA, Carpenters, IBEW members should check union benefit plans

Getting Your Medical Certificate in Ontario

| Option | Timeline | Cost | OHIP Visit? | Best For |
|--------|----------|------|-------------|----------|
| Family doctor | 7-14 day wait | $20-$30 certificate | Yes | If you can wait |
| Walk-in clinic (Toronto/GTA) | Same day (2-5 hr wait) | $20-$40 certificate | Yes | If you need it today |
| Walk-in (smaller cities) | Same day (1-3 hr wait) | $20-$35 certificate | Yes | Shorter waits outside GTA |
| MedLetter | Same day (2-6 hr delivery) | $49 (all-inclusive) | N/A | Speed + convenience |
| Hospital ER | Same day (4-8+ hr wait) | Free (but inappropriate) | Yes | Never for EI certificates |

Application Process: Step-by-Step

Step 1: Get your Record of Employment (ROE)

Your employer must issue within 5 days of your last day worked

Can be electronic (most common) or paper

Check My Service Canada Account, electronic ROEs appear automatically

Step 2: Obtain your medical certificate

Get this as soon as you know you will be off more than 1 week

The certificate should state the start date and expected duration

Keep the original, Service Canada may request it

Step 3: Apply online through My Service Canada Account

Create an account at canada.ca if you do not have one

Complete the sickness benefits application

Have your SIN, ROE, and medical certificate ready

Application takes 30-60 minutes

Step 4: Serve the 1-week waiting period

First week is unpaid (like a deductible)

Benefits begin in week 2

Some employers pay this week under collective agreements

Step 5: Complete bi-weekly reports

Must report every 2 weeks via My Service Canada Account

Confirm you are still unable to work

Report any earnings or return-to-work dates

Step 6: Receive benefits

Direct deposit (fastest, 2-3 business days after approval)

Cheque by mail (7-10 business days)

First payment typically arrives within 28 days of application

Interaction with Ontario Benefits

| Benefit | Can Collect Simultaneously? | Notes |
|---------|---------------------------|-------|
| WSIB | No | Cannot collect for same condition |
| Ontario Disability Support Program (ODSP) | Partial | EI reduces ODSP dollar-for-dollar |
| Ontario Works (OW) | Partial | EI deducted from OW payments |
| Employer STD/LTD | No | Cannot collect both simultaneously |
| ESA sick days (3 days) | Yes (before EI) | Use ESA days first, then apply for EI |
| CPP Disability | No | Different programs for different durations |
| Employer SUB plan | Yes | Tops up EI to 95% (if available) |

Common Mistakes Ontario Workers Make

1. Waiting too long to apply, Apply within 4 weeks of last day worked (benefits only backdated 4 weeks)
2. Thinking OHIP covers the certificate, The visit is free; the certificate is not
3. Not exhausting employer sick leave first, Many employers require this before EI
4. Confusing WSIB with EI sickness, Work injuries go through WSIB (better benefits)
5. Missing the 4-week retroactive limit, Benefits are not backdated more than 4 weeks
6. Not completing bi-weekly reports, Missed reports = missed payments
7. Returning to work without notifying Service Canada, Can create overpayment
8. Self-employed without opt-in, Must have registered 12+ months before claiming

Transitioning from EI Sickness to Other Benefits

If your condition extends beyond 26 weeks:

Employer LTD: Most kick in after 17-26 weeks (check your benefits package)

CPP Disability: For severe, prolonged conditions (12+ months)

ODSP: For Ontario residents with severe disability and financial need

WSIB (if work-related): No time limit for work-related conditions

Key Takeaway

Ontario's OHIP system means the physician visit for your EI medical certificate is free, but you will still pay $20-$40 for the certificate itself, plus spend 2-5 hours waiting at a walk-in clinic. MedLetter's $49 all-inclusive fee with same-day delivery and zero wait time is competitive when you factor in the convenience and speed. Do not let documentation delays hold up your EI sickness benefits application, the 4-week retroactive limit means every day counts.

New sick-note requests are temporarily paused while we review our service. We are not accepting new orders at this time.

Frequently Asked Questions

Can I use an online medical certificate for EI sickness benefits?
Yes. Service Canada accepts medical certificates from any licensed physician or nurse practitioner, including those providing virtual/telehealth care. The certificate must confirm inability to work and expected duration.

How much does an EI medical certificate cost in Ontario?
Walk-in clinics charge $20-$40 for the certificate (visit is OHIP-covered). MedLetter charges $49 all-inclusive with same-day delivery and no wait time.

How long can I receive EI sickness benefits?
Up to 26 weeks (extended from 15 weeks in December 2022). This applies to all new claims filed after the extension date.

Can I work part-time while on EI sickness?
Yes, but earnings are deducted from your benefits. You can earn up to 50 cents of benefits for every dollar earned, up to 90% of your previous weekly earnings. Report all earnings in your bi-weekly reports.

What if my employer has a short-term disability plan?
You typically cannot collect both EI sickness and employer STD simultaneously. Most employers require you to use their STD plan first. If STD is denied or exhausted, you can then apply for EI sickness.

How long does it take to get approved for EI sickness?
Typically 2-4 weeks from application to first payment. Having your medical certificate ready when you apply speeds up the process. Incomplete applications cause delays.
