You called in sick, you got your doctor's note, and you handed it to your employer — and now they are saying they will not accept it. Maybe the format is not what they expected. Maybe they want more detail than the note contains. Maybe they are questioning whether an online physician-issued note is valid. Whatever the reason, you are now in the middle of a dispute over a piece of paper, wondering what your rights actually are.
The short answer is that Canadian employers have limited grounds to refuse a properly issued physician's note. Here is exactly where those limits are, what employers can legitimately push back on, and what to do when a refusal crosses the line.
What employers can and cannot refuse when it comes to a doctor's note
A properly issued physician's note from a licensed Canadian doctor, containing the physician's name, license number, the dates of incapacity, and a statement confirming you were medically unable to work, is legally valid documentation in every province and territory in Canada. Employers are not entitled to refuse it on the grounds that it does not come from a specific clinic, that it was issued by an online service rather than an in-person consultation, or that they personally disagree with the physician's assessment.
What employers can legitimately question is whether the documentation they received satisfies the specific requirement they made. There is a meaningful legal difference between an employer refusing a valid doctor's note outright, and an employer indicating that the documentation provided does not meet the format or content standard required for a particular purpose. The first is generally unlawful. The second may be legitimate depending on the context.
Here is where the distinction plays out in practice. For a standard short-term absence where the employer simply needs confirmation that you were unwell, a physician-signed note meeting the basic requirements is sufficient and an employer cannot refuse it. For a short-term disability application, the insurer's specific physician's statement form must be completed — a general physician's letter may not satisfy that requirement, not because the employer is refusing documentation, but because the insurer's process requires a specific format. For a return-to-work clearance in a safety-sensitive role, the employer may require documentation specifically addressing fitness for the duties of that role, not just a general statement of recovery. These are content requirements, not refusals of valid documentation.
If you are unsure whether what your employer is asking for is a standard sick note, a medical certificate, or a specific form, our post on the difference between a sick note and a medical certificate explains which document applies to which situation.
Is it illegal for an employer to refuse a doctor's note in Canada?
It depends on the grounds for the refusal. Canadian employment law does not contain a single provision that says "employers must accept all doctor's notes" — the legality of a refusal depends on why it is happening and what the employer is doing as a result.
Refusing a valid physician-issued note and then disciplining, penalising, or terminating an employee for the absence that the note covers is where employers run into legal trouble. Under provincial employment standards legislation across Canada, absences covered by statutory sick leave entitlements are job-protected. An employer who refuses to acknowledge a physician-issued note and disciplines an employee for a protected absence may be in violation of employment standards, regardless of their stated reason for the refusal.
Similarly, if an employer refuses documentation because the employee obtained it from an online physician service rather than a traditional clinic, that refusal is on shaky ground legally. Nothing in any provincial employment standards act, human rights code, or health professions legislation requires that a physician's note come from an in-person clinic visit. The note's validity rests on whether the issuing physician is licensed under a provincial College of Physicians and Surgeons — not on the method of consultation. A physician's online consultation and an in-person clinic visit produce documentation of equal legal standing when the issuing physician is licensed in the relevant province.
The situation where an employer's refusal is most clearly unlawful is when the refusal is connected to a disability or health condition. Under provincial human rights codes across Canada and the federal Canadian Human Rights Act, employers have a duty to accommodate employees with disabilities up to the point of undue hardship. Refusing to accept medical documentation that supports an accommodation request, without a legitimate procedural reason, can constitute a failure to fulfil that duty. Employees in that situation have recourse through provincial human rights commissions and tribunals, and through the Canadian Human Rights Commission for federally regulated workplaces.
When an employer can legitimately ask for something different
There are situations where an employer's request for additional or different documentation is genuinely within their rights, and understanding those situations helps you respond appropriately rather than assuming the refusal is unlawful.
If an employment contract or collective agreement specifies the format or content of acceptable medical documentation, the employer can hold employees to that standard. Many collective agreements in unionized workplaces set out specific documentation requirements that go beyond provincial minimums. If your contract specifies that absences of more than five days require a physician's statement on the insurer's standard form rather than a general letter, the employer is within their rights to require that specific format.
If an absence extends into a short-term disability claim, the documentation requirements shift from the employment standards framework to the insurance framework. Insurers operate under their own assessment criteria and their own physician forms. A general sick note that satisfies employment standards may not satisfy the insurer's requirements for a disability claim. These are different legal frameworks covering different purposes, and the documentation requirements for each are set separately. Our standard medical forms service handles insurer-specific physician statement forms for the major Canadian group benefits providers.
If the role involves safety-sensitive duties — operating heavy equipment, working in a clinical setting, driving commercially, or handling food — an employer in a safety-sensitive industry may be entitled to require specific functional capacity information before allowing a return to work. This is a legitimate occupational health and safety requirement, not a refusal of medical documentation. The appropriate document in that situation is a fitness-to-work certificate that addresses specific functional requirements, rather than a general absence note. Our medical certificates page covers standard extended leave documentation, and our fitness certificates service covers return-to-work clearance for safety-sensitive roles.
What to do if your employer refuses your doctor's note
If your employer has refused your note and you believe the refusal is unjustified, the steps below give you the clearest path forward.
First, get the refusal in writing. If your employer told you verbally that they would not accept your note, follow up by email asking them to confirm the specific reason for the refusal and what documentation they would accept instead. A clear written record of their position protects you if the situation escalates, and sometimes prompts employers to reconsider a refusal that was more reflexive than considered.
Second, check whether the refusal is about format rather than validity. If your employer says they need a specific form completed rather than a physician's letter, that may be a legitimate content requirement rather than an outright refusal. Identify exactly what form they need, and request it through our standard medical forms service if it is a physician's statement or insurer form. Most format objections can be resolved by obtaining the correct document the first time.
Third, if your employer is refusing a valid physician's note and disciplining you for an absence that was covered by your statutory sick leave entitlement, contact your provincial employment standards office. Employment standards complaints are free to file and can result in orders requiring the employer to reverse the disciplinary action. For absences connected to a disability or medical condition that requires accommodation, a human rights complaint to your provincial human rights commission is available as a separate or concurrent route.
For employees whose situation involves a probationary period, our post on sick leave during probation in Canada covers the additional dimensions that apply when you are still within your probationary window.

Can you get a doctor's note from a walk-in clinic and will employers accept it?
Walk-in clinic physician notes are valid and accepted by Canadian employers in the same way as notes from family doctors. The note's validity does not depend on the physician having a prior relationship with the patient, or on the patient having a registered family doctor. Any licensed physician can issue a valid sick note for any patient they have assessed, regardless of the clinical setting in which that assessment occurs.
The same principle applies to notes issued by online physician services. A physician licensed under their provincial College of Physicians and Surgeons who conducts a virtual consultation and issues a note is producing documentation of identical legal standing to that produced by an in-person clinic visit. The consultation method is not a criterion for validity under any provincial employment standards act, health professions legislation, or human rights code in Canada.
Where employers sometimes push back on walk-in or online notes is when the note contains only the minimum information — a statement that the patient was assessed and was unable to work — without the specific content required for the purpose at hand. A note that satisfies a short-term absence requirement may not satisfy a disability claim. The solution is not a different source for the note, but a different type of document. Our post on sick leave rights in Canada outlines what documentation is required at each stage of a leave. If you need physician documentation today for a work absence, visit our sick leave notes page to submit your request and receive your documentation within 2 to 4 hours.
Frequently asked questions
Can an employer refuse a doctor's note in Canada?An employer cannot refuse a properly issued physician's note on the grounds of its source or the method of consultation. They can indicate that the documentation does not meet a specific format or content requirement for a particular purpose, such as a disability claim or return-to-work clearance in a safety-sensitive role. Refusing a valid note and disciplining an employee for a protected absence is a potential violation of provincial employment standards.
Is it illegal to not accept a doctor's note for work in Canada?Outright refusal of a valid physician-issued note, followed by disciplinary action against an employee for a protected absence, can violate provincial employment standards legislation. The legality depends on the grounds for refusal and the consequence attached to it. A format objection for a specific purpose, such as requiring an insurer's form rather than a general letter for a disability claim, is not necessarily unlawful.
Do employers have to accommodate a doctor's note in Canada?Yes, within limits. Employers have a duty to accommodate employees with disabilities, including health conditions, up to the point of undue hardship under provincial human rights codes and the federal Canadian Human Rights Act. A physician's note supporting an accommodation request triggers that duty. Employers cannot refuse accommodation without demonstrating that providing it would cause undue hardship.
Can my employer refuse a note from an online doctor in Canada?No, on the grounds of the consultation method alone. A physician licensed under a provincial College of Physicians and Surgeons who issues a note following a virtual consultation is producing legally valid documentation. The note's validity rests on the physician's licensing, not on whether the assessment was in person. Canada Medical Notes physicians are licensed under provincial colleges and issue documentation accepted by employers across all provinces.
What do I do if my employer refuses my doctor's note?Get the refusal in writing with the specific reason stated. Check whether the objection is about format rather than validity — if so, obtain the correct document. If the refusal is unjustified and disciplinary action follows, contact your provincial employment standards office. If the absence is connected to a disability requiring accommodation, a human rights complaint is also available.
Can a company refuse a doctor's note if they think it is fake?If an employer has a genuine good-faith concern about the authenticity of a physician's note, they can verify the issuing physician's license through the provincial college's public registry. They cannot simply declare a note invalid without a specific basis for that concern. If a note is genuine and verifiable, refusal on suspicion alone is not a defensible position under employment standards or human rights law.
