Missed Work Due to Illness? Here's What to Do

A practical guide for Canadian workers - how to notify your employer, when you need a note, and your rights under employment law.

Getting sick is stressful enough without worrying about your job. Whether it is a sudden flu, a mental health day, or a chronic condition flare-up, Canadian workers have legal protections for illness-related absences. Here is a step-by-step guide to handling it properly.

Step 1: Notify Your Employer Early

Notify your supervisor or HR as early as possible - ideally before your shift starts. Follow your workplace's notification procedure (phone call, email, text, or through a scheduling system).

What to say:

  • "I'm unwell and unable to come in today."
  • Provide an expected return date if you can ("I expect to be back on [date]")
  • Ask about any documentation requirements

You do not need to share detailed medical information. Under Canadian privacy law, your employer can only ask for confirmation that you are ill, not the specifics of your condition.

Step 2: Understand Your Sick Leave Rights

Every Canadian province provides minimum sick leave entitlements. The number of days varies by province, but the core principle is the same: you cannot be punished for taking legitimate sick leave.

Additionally, check your employment contract - many employers provide more generous sick leave than the statutory minimum. Union members should review their collective agreement.

Step 3: Get a Doctor's Note If Needed

If your employer requires a doctor's note, you have several options:

  • Telehealth (fastest): Same-day virtual consultations with a licensed physician - typically takes 10-15 minutes
  • Family doctor: If you have one and can get an appointment quickly
  • Walk-in clinic: Expect 2-4 hour waits, and you may pay a separate fee for the note

Step 4: Know Your EI Sickness Benefits Options

If your illness keeps you off work for more than a few days, you may qualify for Employment Insurance (EI) sickness benefits:

  • Up to 26 weeks of benefits
  • 55% of your average insurable weekly earnings (max $695/week in 2026)
  • Requires a medical certificate from a physician
  • Apply online through Service Canada within 4 weeks of your last working day

Common Illnesses and Documentation

What If You Cannot Afford to Miss Work?

Financial pressure is a reality for many Canadians. If you are worried about lost income:

  • Check if your province has paid sick days (BC offers 5 paid days; federally regulated workers get 3)
  • Apply for EI sickness benefits for extended absences
  • Ask your employer about short-term disability benefits
  • Some municipalities offer emergency financial assistance for workers in temporary hardship

Frequently Asked Questions

Can I be fired for calling in sick in Canada?

Canadian employment law protects employees from termination due to legitimate illness. All provinces provide job-protected sick leave. However, you must follow your employer's absence notification procedures and provide documentation if requested.

Do I need a doctor's note for one sick day?

It depends on your employer's policy and your province. Most provinces do not require a note for short absences (1-2 days), but your employer's workplace policy may. When in doubt, check your employment contract or employee handbook.

How do I tell my boss I'm calling in sick?

Notify your supervisor as early as possible by phone, email, or whatever method your workplace policy specifies. You do not need to provide detailed medical information - simply state that you are unwell and unable to work. Provide an expected return date if possible.

Can I get a sick note after I've already recovered?

In some cases, a physician can issue a note retroactively. However, it is best to consult a physician as close to the absence as possible. MediNote offers same-day appointments to help you get documentation promptly.
