How Many Sick Days Can You Take Without a Doctor's Note in Ontario?

Under Ontario's Employment Standards Act (ESA), employers cannot require a medical certificate for the first 3 unpaid sick days per year. After that, employer policies vary. Many Ontario employers request documentation after 3 consecutive days of absence.

Ontario's ESA Sick Leave Rules (2026)

The Ontario Employment Standards Act provides employees with 3 unpaid sick days per year. For these 3 days, employers are explicitly prohibited from requiring a doctor's note or medical certificate. This was a deliberate policy decision to reduce unnecessary healthcare visits.

After Your 3 ESA Days

Once you've used your 3 ESA-protected sick days, your employer's internal policy takes over. Most Ontario employers have policies that require documentation for:

• Any absence beyond the 3 ESA days
• 2+ consecutive days off (common in retail/hospitality)
• 3+ consecutive days off (common in office/corporate)
• Pattern absences (e.g., always sick on Mondays/Fridays)
• Absences before or after a holiday weekend

Unionized Workplaces in Ontario

If you're covered by a collective agreement in Ontario, your sick leave provisions may be more generous than the ESA minimums. Many Ontario unions have negotiated 5-10 paid sick days with specific documentation thresholds written into the agreement.

The Practical Reality

Even though the ESA protects your first 3 days, many Ontario employees still get notes for protection. If you're in a probationary period, have had attendance issues, or work in a competitive environment, a $49 sick note provides peace of mind.
