Can My Employer Require a Sick Note?
The short answer: It depends on your province and the length of your absence. Some provinces explicitly protect short absences from documentation requirements. Others give employers broad discretion.
Province-by-Province Rules
| Province | Can Employer Require a Note? | Protected Period | Key Law |
|---|---|---|---|
| Ontario | Limited | First 3 sick days/year — NO note required | ESA s. 50(7.1) |
| British Columbia | Yes, but "reasonable" standard | 5 paid + 3 unpaid days (reasonable proof) | ESA s. 49.1 |
| Alberta | Yes, for any absence | No protected period | Employment Standards Code |
| Saskatchewan | Limited | First 3 consecutive days — NO note required | Employment Act s. 6-25 |
| Manitoba | Limited | First 3 days/year — NO note required | Employment Standards Code s. 59.2 |
| Nova Scotia | Yes, for any absence | No protected period | Labour Standards Code |
| New Brunswick | Yes, for any absence | No protected period | Employment Standards Act |
| PEI | Limited | First 5 days — NO note required | Employment Standards Act (2026) |
| Newfoundland | Yes, for any absence | No protected period | Labour Standards Act |
| Federal | Limited | First 3 days/year — NO note required | Canada Labour Code s. 239 |
What "Cannot Require" Actually Means
In provinces with protected periods (Ontario, Saskatchewan, Manitoba, PEI, Federal), "cannot require a sick note" means:
- Your employer cannot demand a certificate from a physician or health practitioner
- They cannot discipline you for refusing to provide one during the protected period
- They cannot deny your sick day because you didn't bring a note
However, they CAN:
- Ask for "evidence reasonable in the circumstances" (Ontario) — which could be a written self-declaration
- Request documentation for absences beyond the protected period
- Require notes under their company policy for non-statutory sick days
What "Can Require" Means in Practice
In provinces without protection (Alberta, Nova Scotia, New Brunswick, Newfoundland):
- Your employer can require a note for any absence, even 1 day
- They can make it a condition of approving your sick day
- They can discipline you for not providing one (if their policy requires it)
But there are still limits:
- The request must be "reasonable" (courts have found requiring notes for every single-day absence unreasonable in some cases)
- They cannot require information beyond what's legally permitted (no diagnosis)
- Human rights law may override if the requirement disproportionately affects people with disabilities
Common Employer Overreach
Things your employer CANNOT do, regardless of province:
1. Require your specific diagnosis — They can ask for a note confirming inability to work, not what's wrong with you
2. Contact your doctor directly — Without your written consent, this violates privacy law
3. Require a note from a specific doctor — You can use any licensed physician
4. Reject a note because it's from an online service — Virtual care notes are legally equivalent
5. Require a note during protected periods — In provinces with protections, this is illegal
What If Your Employer Requires a Note Anyway?
If you're in a protected province and your employer demands a note for a short absence:
Option 1: Comply anyway. Getting a note ($49 online) may be easier than fighting about it. This doesn't waive your rights.
Option 2: Politely decline. Cite the specific legislation: "Under Section 50(7.1) of the ESA, you cannot require a medical certificate for my first 3 sick days."
Option 3: File a complaint. Contact your provincial employment standards office if your employer retaliates.
Unionized Workers
If you're covered by a collective agreement, your sick note requirements are governed by that agreement — which may be more or less generous than provincial minimums. Check your collective agreement or ask your union representative.
Frequently Asked Questions
Can my employer require a note for a mental health day?
The same rules apply regardless of whether your absence is for physical or mental health. No province distinguishes between the two.
Can my employer require a note if I work from home?
Yes. Working remotely doesn't change your employment standards obligations. The same provincial rules apply.
What if my employer's handbook says "note required for any absence"?
Company policies cannot override provincial employment standards. If your province protects short absences, that protection applies regardless of what the handbook says.
Can I be fired for refusing to provide a sick note?
In protected provinces, no — for absences within the protected period. In unprotected provinces, potentially yes, if it's a clear policy violation. However, termination for a single instance would likely be considered excessive.
