Last reviewed and updated: August 2026 by a licensed Canadian physician

You got a sick note from a doctor, submitted it to your employer, and they rejected it. Can they do that? Here's what Canadian law says about employer refusal of medical documentation.


100% Refund Guarantee: If your request is declined for any reason, you receive a full refund — no questions asked. Our physician reviews every submission personally, and you only pay if your sick note is approved and delivered.


How It Works — 3 Simple Steps


Step 1: Fill out our secure 2-minute intake form with your basic information and reason for needing a sick note.


Step 2: A licensed physician reviews your submission and assesses your situation (no video call required).


Why Choose MedLetter Over a Walk-In Clinic?


Walk-in clinic: 2-4 hour wait, $20-50 fee, only open weekdays 9-5, may not have availability, requires driving and parking.


MedLetter: 2-minute form, $49 flat fee, available 24/7 including weekends and holidays, same-day delivery, no appointment or video call needed. Same legal validity — signed by a licensed physician registered with the provincial College.

Step 3: Your signed sick note is delivered to your email — same-day for most requests submitted before 3 PM.


The entire process takes less time than driving to a walk-in clinic parking lot. New sick-note requests are temporarily paused while we review our service. We are not accepting new orders at this time..

No Family Doctor? No Problem.


Over 6.5 million Canadians don't have a family doctor — and that number is growing. If you need a sick note but have no GP, your options are limited: wait 3-5 hours at a walk-in clinic, or use MedLetter. Our licensed physician reviews your request online and delivers your official sick note the same day for $49. No referral needed, no appointment required.

Shift Workers, Retail Staff, and Warehouse Employees


If you work shifts, nights, or weekends, getting a sick note during clinic hours is nearly impossible. Night shift workers can't visit a walk-in clinic at 3 AM. Retail employees at Walmart, Costco, or Tim Hortons often can't take time off during clinic hours. Warehouse workers at Amazon, Purolator, or FedEx face strict attendance policies. MedLetter is available 24/7 — submit your request at any hour, from your phone, and receive your official physician-signed sick note the same day. No appointment, no wait, no missing another shift to get documentation for the shift you already missed.


On Probation at a New Job?


If you're in your first 90 days at a new job, calling in sick without documentation can be career-ending. Probationary employees are often terminated for a single unexcused absence. Don't risk your new position — get official physician documentation from MedLetter for $49 same-day. Protect your job while you recover from your illness.

Also known as: doctor's note, medical certificate, absence note, fitness-to-work letter, or medical documentation for employer. MedLetter provides all of these — same document, same $49 flat fee, same-day delivery.

Weekend and Holiday Sick Notes


Got sick on a Saturday or Sunday? Every walk-in clinic is either closed or has a 4+ hour wait on weekends. MedLetter is available 7 days a week, including all statutory holidays (Thanksgiving, Christmas, New Year's, Family Day, Victoria Day, Canada Day, Labour Day). Submit your request any time — even at 2 AM on a Sunday — and receive your physician-signed sick note before Monday morning. Perfect for workers who need documentation for their Monday shift.


Need Your Sick Note Right Now?


If you're reading this at 11 PM because your boss just texted asking for a doctor's note by tomorrow morning — we can help. MedLetter accepts requests 24/7. Most notes submitted before 3 PM are delivered same-day. Evening and weekend submissions are typically reviewed within hours. No appointment, no waiting room, no video call.

Need a Sick Note After Hours?


It's 10 PM and you just realized you need a doctor's note for tomorrow morning. Walk-in clinics are closed. Your family doctor's office doesn't open until 9 AM — by then you're already late for work. MedLetter accepts requests 24/7, including evenings, weekends, and holidays. Submit at midnight, receive your note before your shift starts.

Can My Employer Refuse My Sick Note?

You did everything right: you called in sick, saw a doctor (or used an online service), got a legitimate sick note, and submitted it to your employer. Then they said it wasn't acceptable. This situation can be incredibly stressful, especially when you are already dealing with an illness and just want to focus on your recovery. The anxiety of potentially losing your job or facing disciplinary action can make your symptoms worse.

Can they do that? In most cases, no. But there are limited circumstances where an employer can question New sick-note requests are temporarily paused while we review our service. We are not accepting new orders at this time.. Understanding your rights as an employee in Canada is crucial to protecting your job and your health. Without proper documentation, you risk losing pay, facing disciplinary action, or even termination. Don't leave your job security to chance.

When an Employer CANNOT Refuse Your Note

Your employer cannot reject your sick note if it meets the basic legal and medical standards established across Canadian provinces. The law generally protects employees who provide valid medical documentation. Specifically, your employer must accept your note if:

  • It's from a provincially-registered physician (such as those registered with the CPSO in Ontario, CPSA in Alberta, or CPSBC in British Columbia).

  • It contains the standard required information (physician name, registration number, dates of absence, and signature).

  • It confirms your inability to work during the stated period due to medical reasons.

  • It was obtained through a legitimate medical assessment (whether in-person, by phone, via video, or through a written consultation).


Specifically, they cannot refuse because:
  • The note is from a walk-in clinic rather than your family doctor. Many Canadians do not have a family doctor, and walk-in clinics are a perfectly valid source of medical care.

  • The note is from an online or virtual service. Telemedicine is fully recognized by provincial medical colleges across Canada.

  • The note doesn't include your specific diagnosis. Your medical history is private, and employers are not entitled to know exactly what illness you have.

  • The note is "too brief". As long as it contains the required information, brevity is not a valid reason for rejection.

  • They "don't trust" the physician. Unless they have concrete proof of fraud, an employer's personal feelings about a doctor are irrelevant.

  • The note was obtained after your absence (retroactive). Doctors can often assess an illness after the fact based on your reported symptoms.

When an Employer MAY Question Your Note

While employers must generally accept valid sick notes, there are limited circumstances where an employer can raise concerns or request additional information. It is important to know the difference between a legitimate request and an overreach.

| Situation | Employer's Right |
|---|---|
| Note is clearly fraudulent (fake physician, wrong dates) | Can investigate and potentially discipline the employee. |
| Note doesn't contain required information | Can ask you to get a more complete note with the missing details. |
| Note is from an unregistered practitioner | Can request one from a registered physician. |
| Extended absence (weeks or months) | Can request an independent medical examination (IME). |
| Accommodation request | Can request more detail about functional limitations to provide proper support. |
| Pattern of suspicious absences | Can request a second opinion (at their cost). |

If you find yourself in a situation where your employer is questioning your note, having a professionally issued document from a licensed Canadian physician is your best defense. Don't risk using questionable services. New sick-note requests are temporarily paused while we review our service. We are not accepting new orders at this time. from MedLetter.

The Independent Medical Examination (IME)

For extended absences or complex accommodation requests, employers may request an Independent Medical Examination (IME). Search "sick note near me" and get yours delivered same-day. This is a formal process and is not used for standard, short-term illnesses.

  • Who pays: The employer is entirely responsible for paying for the IME.

  • Who chooses the doctor: The employer selects the physician, but the physician must be qualified and impartial.

  • Your rights: You have the right to have someone accompany you to the examination, and you are entitled to receive a copy of the final report.

  • When it's appropriate: IMEs are typically used for extended leaves, complex return-to-work disputes, or significant accommodation disagreements where specialized medical insight is needed.

  • When it's NOT appropriate: An IME is completely inappropriate for simple 1 to 5 day sick notes for common illnesses like the flu or a cold.


What to Do If Your Note Is Refused

If your employer refuses your sick note, it is crucial to handle the situation professionally and document everything. Follow these steps to protect your rights:

Step 1: Ask for the reason in writing. Always communicate via email or written letter. Say, "Can you please explain in writing why my sick note is not being accepted?" This creates a paper trail.

Step 2: Review the stated reason. Analyze their response. Is it a legitimate concern (like missing the doctor's signature) or an illegitimate excuse (like claiming they don't accept online notes)?

Step 3: If the reason is illegitimate:

  • Cite the relevant law, such as provincial employment standards or the medical college's recognition of virtual care.

  • Put your response in writing (email) to maintain the paper trail.

  • Contact your union representative immediately, if you are part of a union.

  • File a formal complaint with your provincial employment standards office if the issue cannot be resolved internally.


Step 4: If the reason is legitimate:
  • Get a more complete note that addresses their specific, valid concerns.

  • Have the physician reissue the document with the required details.


Don't wait until you are facing disciplinary action. Ensure you have a valid, comprehensive sick note from the start. New sick-note requests are temporarily paused while we review our service. We are not accepting new orders at this time..

Common Illegitimate Refusal Reasons

Employers sometimes use invalid reasons to reject sick notes. Here are the most common illegitimate excuses and why they are wrong:

"We don't accept online sick notes."
This is absolutely not a valid reason. Provincial medical colleges across Canada fully recognize virtual care and telemedicine. There is no legal basis for an employer to distinguish between an in-person assessment and an online assessment. Both are equally valid under the law.

"We need a note from YOUR doctor."
Unless your specific employment contract explicitly requires this (which is exceedingly rare), you can get a note from any registered physician in your province. Given the shortage of family doctors in Canada, this demand is often unreasonable and unenforceable.

"The note doesn't say what's wrong with you."
Your employer is NOT entitled to your specific medical diagnosis. Your health information is private. A note confirming your inability to work for a specific period is entirely sufficient for a standard sick leave.

"You got the note after you were already better."
Retroactive medical assessments are a legitimate and common medical practice. A physician can provide documentation for a past illness based on your reported symptoms and medical history.

"This note is too short or not detailed enough."
A standard sick note only needs a few key pieces of information: the physician's name, their registration number, the date of the assessment, the period of your absence, and a signature. It does not need to be a comprehensive medical essay.

MedLetter vs. Walk-In Clinics: The Smart Choice

When you need a sick note, you have options, but they are not all equal. Let's compare getting a note from MedLetter versus a traditional walk-in clinic.

The Walk-In Clinic Experience:

  • Wait Times: You can expect to wait anywhere from 2 to 4 hours in a room full of other sick people.

  • Cost: Many clinics charge between $20 and $50 specifically for the sick note, on top of the time you waste.

  • Convenience: You have to travel while feeling unwell, find parking, and sit in uncomfortable chairs.

  • Exposure: You risk catching other illnesses while waiting.


The MedLetter Experience:
  • Wait Times: Zero wait time. You can complete the process online in minutes.

  • Cost: A flat fee of $49 for a comprehensive, legally valid sick note.

  • Convenience: Same-day delivery directly to your email. You don't even have to leave your bed.

  • Quality: Issued by licensed Canadian physicians, ensuring your note meets all legal requirements.


Why suffer in a waiting room when you can get exactly what you need from the comfort of your home? New sick-note requests are temporarily paused while we review our service. We are not accepting new orders at this time..
