Can your employer legally ask for a doctor's note in Canada?

Most Canadian employees have faced this at some point. You call in sick, and your employer asks for a doctor's note. The question is whether that request is legal — and what you are actually required to hand over.

The answer depends on your province and how many days you have been off. Here is what the law says.

What Canadian employment law says about sick notes

There is no single federal law that governs sick note requirements for all employees. The rules come from provincial employment standards legislation, and they differ.

Under the Canada Labour Code, federally regulated employees — those working in banking, airlines, telecommunications, and interprovincial transport — cannot be required to produce a medical certificate for absences under three consecutive days.

For employees covered by provincial law, here is how the major provinces handle it:

Ontario. The Employment Standards Act allows employers to ask for evidence of illness but does not require it to come from a doctor specifically. A note from a nurse practitioner is as valid as one from a physician.

British Columbia. Employers can request proof for absences of three or more days. They cannot require the employee to pay for the cost of obtaining that documentation.

Alberta. Employers can request medical documentation for absences longer than five consecutive days under the Employment Standards Code.

Quebec. Employees are entitled to two days of paid sick leave per year. Employers can request proof after a reasonable period of absence.

Nova Scotia, Manitoba, Saskatchewan. All permit employers to request documentation, typically after three or more consecutive days.

One rule holds across most provinces: an employer cannot require you to see a specific doctor, and in many provinces they cannot make you pay out of pocket to get the note.

What a valid doctor's note must include : employer ask for doctor's note Canada

A valid sick note in Canada does not need to contain your diagnosis. Your medical history is private under provincial privacy legislation. What a note does need to include:

• Confirmation that you were seen by a licensed medical professional

• The date of the assessment or consultation

• A statement that you were unfit for work during a specific period

• The physician's name, signature, and license number

Employers who ask for your specific diagnosis or a detailed account of your condition are overstepping. If a request seems unreasonable, your provincial employment standards office can tell you whether it is.

Why getting a note quickly is harder than it sounds

Getting an appointment with a family doctor in Canada takes an average of 7.4 days, according to the 2023 Commonwealth Fund International Health Policy Survey. Walk-in clinics in Toronto and Vancouver routinely have two to four hour wait times.

For employees who need documentation quickly — particularly for a one to three day absence — an online sick leave note from a licensed Canadian physician is a practical option. A licensed doctor reviews your request and prepares a note on official letterhead, including their license number. The note is delivered to your inbox the same day.

This meets the documentation requirements under provincial employment standards. The note confirms the absence period and is signed by a licensed physician, which is exactly what employers are permitted to ask for.

What employers cannot do

There are clear limits on what an employer can require:

• They cannot refuse a note because it came from a walk-in clinic or online service, as long as the physician is licensed

• They cannot require disclosure of your diagnosis

• They cannot dock your pay for a legitimate medical absence without cause in provinces with job-protected sick leave

• They cannot discipline you for using sick leave you are entitled to under your employment contract or provincial standards

If you believe your employer has acted outside these limits, contact your provincial employment standards branch. In Ontario, that is the Ministry of Labour. In BC, it is the Employment Standards Branch.

Frequently asked questions

Can my employer fire me for taking sick leave in Canada?

Terminating an employee because they took a legitimate medical leave is prohibited under most provincial employment standards laws and the Canadian Human Rights Act. An employer can still terminate for unrelated reasons during or after a medical leave, but the leave itself cannot be the cause.

Does the note have to come from my family doctor?

No. A note from any licensed physician, nurse practitioner, or in some provinces a registered nurse, is generally acceptable. The requirement is that the person who signed it holds a valid medical license.

How long does a doctor's note have to cover?

The note should cover the specific period of your absence. If you were off Monday to Wednesday, the note should state you were unfit for work on those dates.

Can I get a doctor's note without a family doctor?

Yes. Walk-in clinics, telehealth services, and online medical documentation services all provide notes from licensed physicians. Not having a registered family doctor has no effect on your ability to get valid documentation.

What to do if your employer has asked for a note

If you need documentation quickly, your options are a walk-in clinic, a telehealth service, or an online sick leave note from Canada Medical Notes. Licensed Canadian physicians prepare the note and deliver it to your email the same day. Employer ask for doctor's note Canada
