Getting a doctor's note in Ontario should be simple. You were sick, you need documentation, and you want it before your employer starts asking questions. In practice, over 2.2 million Ontarians do not have a family doctor as of 2026, according to the Ontario College of Family Physicians, and the walk-in clinic system that fills that gap has wait times ranging from two to six hours depending on the city. This guide covers every way to get a doctor's note in Ontario, what it will cost you, what your employer can and cannot legally ask for, and the fastest option available in 2026.
Your four options for getting a doctor's note in Ontario
Ontario residents have four realistic paths for obtaining a physician-signed note, each with different trade-offs on time, cost, and availability.
Your family doctor. If you are among the 75 percent of Ontarians who have a registered family physician, this is the most straightforward path for non-urgent documentation. Your GP can include a sick note or medical certificate as part of a covered consultation under OHIP, meaning there may be no additional fee for the documentation itself when provided during a scheduled appointment. The limitation is access. The Ontario Medical Association confirmed in 2026 that the province needs more than 2,400 additional family physicians to meet current demand. Booking a same-day or next-day appointment with a GP for an administrative request places you behind urgent clinical cases, and wait times of five to ten business days for non-urgent appointments are common in cities across the province.
Walk-in clinics. Walk-in clinics are the default option for the 25 percent of Ontarians without a family doctor. Any licensed physician at a walk-in clinic can issue a valid sick note or medical certificate for a patient they assess, regardless of prior patient history. The challenge is capacity. Walk-in clinics across Ontario have average wait times that vary significantly by city. According to Medimap data and clinic network reporting, Toronto and Mississauga clinics average three to five hours during peak periods, with many closing intake before 10 am once their daily patient cap is reached. Brampton records some of the longest waits in the province at four to six hours, driven by the city's documented physician-to-population ratio of 70 per 100,000 residents versus the national average of 124. Ottawa averages two to four hours, London and Windsor two to four hours, Hamilton two to three hours, and Kitchener-Waterloo two to three hours.
Urgent care centres and hospital emergency departments. For Ontarians who cannot access a walk-in clinic, hospital emergency departments and urgent care centres are technically an option for obtaining a doctor's note. They are not a practical one. Presenting to an emergency department for administrative documentation places you at the bottom of the triage queue. Wait times at major Ontario hospitals for non-urgent presentations regularly exceed four hours, and many emergency physicians decline to provide administrative documentation for non-clinical visits on the grounds that it diverts resources from acute care.
Online physician services. The College of Physicians and Surgeons of Ontario (CPSO) fully recognizes virtual care as a legitimate form of medical practice. A physician licensed under the CPSO can conduct a virtual consultation and issue a valid sick note, medical certificate, or other physician-signed documentation with the same legal standing as documentation issued following an in-person visit. Canada Medical Notes connects Ontario residents with CPSO-registered physicians online. You submit your request from home, describe your situation, and receive your documentation within 2 to 4 hours. Visit our sick leave notes page to submit your request, or our medical certificates page if your situation requires more detailed physician documentation.
How much does a doctor's note cost in Ontario?
Doctor's notes are not covered by OHIP. Under Ontario's Health Insurance Act, OHIP covers medically necessary clinical services but not the administrative work of preparing, signing, and issuing formal documentation. This means that whether you see a walk-in clinic physician or your own family doctor, the preparation of a sick note or medical certificate is an uninsured service for which the physician or clinic can charge a separate fee.
At Ontario walk-in clinics, fees for a standard sick note or medical absence letter typically range from $20 to $50. Some Toronto clinics in higher-demand areas charge at the upper end of this range or slightly above. Medical certificates for more specific purposes, including short-term disability applications, EI sickness benefit documentation, return-to-work clearances, and fitness-to-work assessments, attract higher fees because they require more physician time and more detailed clinical assessment. The Ontario Medical Association publishes an annual guide to suggested fees for uninsured services that most physicians and clinics use as a benchmark for these more complex documents.
Your family doctor may provide a sick note as part of a covered appointment at no additional charge if the documentation request arises during a clinical visit for the same illness. However, if you request documentation as a standalone administrative service, most Ontario family practices charge the uninsured fee regardless of your registration with the practice.
An important Ontario-specific note: unlike British Columbia, Ontario has no law requiring employers to reimburse employees for the cost of physician documentation that the employer has requested. In BC, if your employer specifically asks you to obtain a doctor's note, they may be required to cover the cost. In Ontario, the cost is generally your responsibility unless your employment contract or collective agreement specifies otherwise. That said, many Ontario employers, particularly larger organizations with formal HR policies, voluntarily reimburse documentation fees when they have explicitly requested the documentation.

Ontario's 2024 sick note rules: what changed and what your employer can still ask for
Ontario made a significant change to its sick note rules on October 28, 2024, and many Ontario employees and employers are still navigating exactly what the change means in practice.
Under amendments to Ontario's Employment Standards Act that came into force on that date, Ontario employers are prohibited from requiring a certificate from a qualified health practitioner — defined to include physicians, registered nurses, and psychologists — as evidence for the three unpaid statutory sick days that employees are entitled to under the ESA. Before October 2024, employers could legally demand a physician-signed note for even a single sick day. That is no longer permitted for ESA-protected absences.
The change was introduced specifically because of the strain that Ontario's primary care system was already under. The Ontario College of Family Physicians had documented that Ontario physicians were spending significant portions of their clinical time writing notes for short absences — time that would otherwise be spent on patients with genuine clinical needs. Redirecting patients away from clinics for administrative notes during minor illnesses was creating unnecessary system pressure and public health risk.
However, the October 2024 change is narrower than many Ontario employees assume, and there are several important situations where physician documentation is still fully within your employer's rights to request.
The prohibition covers only the three ESA statutory sick days. It does not apply to absences of four or more consecutive days, to extended medical leaves of any duration, to short-term or long-term disability benefit applications through your employer's group plan, to return-to-work clearances after significant illness or injury, or to any documentation requirement set out in your specific employment contract or collective agreement that goes beyond the ESA minimum. Many Ontario employers, particularly in healthcare, manufacturing, government, and financial services, have internal HR policies that require physician documentation for absences longer than three days regardless of the ESA change. Those policies remain legally valid.
For absences of five days or more, a medical certificate is typically required rather than a basic sick note. Our post on the difference between a sick note and a medical certificate explains which document your situation requires and what each one must include. For a full breakdown of what Ontario employers can and cannot legally require before and after October 2024, see our existing post on whether your employer can legally ask for a doctor's note in Canada.
Getting a doctor's note in Ontario by city
Ontario has 14 cities with populations over 100,000, and access to walk-in clinic documentation varies significantly across them. Here is what the situation looks like in the cities where the most Ontario residents are searching for documentation help.
Toronto. The Ontario Medical Association confirmed that 4.4 million Ontarians — roughly one in four — are without a family doctor, with Toronto residents among the most severely affected. Walk-in clinics in the city average three to five hours during peak periods, and many reach their daily patient cap before noon. For same-day documentation without a clinic visit, visit our doctor's note in Toronto page.
Ottawa. Ottawa residents who need a doctor's note face the added complexity of a dual-workforce situation. A significant portion of Ottawa's workforce is federally regulated under the Canada Labour Code rather than Ontario's ESA, which means different sick leave rules apply. Federal employees have access to 10 days of paid medical leave and face different documentation thresholds. Walk-in wait times in Ottawa average two to four hours. For same-day documentation, visit our doctor's note in Ottawa page.
Brampton. Brampton has the longest documented walk-in clinic wait times of any Ontario city at four to six hours, driven by having only one full-service hospital for nearly 700,000 residents and one of the province's lowest physician-to-population ratios at 70 per 100,000. For same-day documentation, visit our doctor's note in Brampton page.
Mississauga. The Ontario College of Family Physicians projected that up to 430,000 people across Mississauga, Brampton, and Caledon would be without a family doctor by 2026. Walk-in wait times in Mississauga average three to five hours. For same-day documentation, visit our doctor's note in Mississauga page.
Hamilton. Hamilton's family physician shortage affects approximately 100,000 residents, with walk-in clinics averaging 68 minutes during off-peak hours and significantly longer during peaks. For same-day documentation, visit our doctor's note in Hamilton page.
London Ontario. At least 100,000 London residents lack a primary care physician. Western University's Schulich School of Medicine trains approximately 84 new family doctors annually, but retirements continue to outpace new attachments. For same-day documentation, visit our doctor's note in London Ontario page.
What your Ontario doctor's note must include
For a doctor's note to be accepted by an Ontario employer, HR department, university, or insurer, it needs to contain specific information regardless of whether it was obtained from a walk-in clinic, family doctor, or online service.
The note must include the issuing physician's full legal name and CPSO registration number. The date of the consultation or assessment must be included. The note must confirm that you were medically unable to work or attend school on the relevant dates, and where applicable, provide an expected return date or state that the return date cannot yet be determined. If the note is for a return-to-work clearance rather than documenting an absence, it must state that you are medically fit to resume your duties, with any restrictions specified.
What a doctor's note is not required to include is your specific diagnosis, your medication, your treatment plan, or any other clinical health information beyond what is necessary to confirm the purpose of the note. Ontario's Personal Health Information Protection Act (PHIPA) protects your detailed medical information as private. Your employer is entitled to know that you were medically unable to work and for how long. They are not entitled to know the nature of your condition unless you choose to disclose it.
Canada Medical Notes prepares documentation that includes all required fields in the format Ontario employers, universities, and insurers expect. If your employer has provided a specific form to be completed rather than accepting a standard physician's letter, that falls under our medical certificates service where insurer and employer-specific forms are handled.

How long is sick leave in Ontario?
Ontario's sick leave framework has multiple layers, and knowing how long your leave can last determines what documentation you need at each stage.
The first layer is the three unpaid ESA statutory sick days per calendar year, available after two consecutive weeks of employment. For these days, Ontario employers cannot require physician documentation under the October 2024 amendments. A basic sick note is not necessary unless your employer's policy beyond the ESA minimum requires it.
For absences beyond three days, your employer's policy and any group benefits plan determine what happens next. Many Ontario employers offer their own paid sick day provisions through their employment contract or collective agreement that go beyond the ESA minimum. If you have short-term disability coverage through your group benefits plan, that typically kicks in after a waiting period of five to seven business days and covers 60 to 70 percent of your salary for up to 17 weeks.
Ontario's long-term illness leave provides up to 27 weeks of unpaid, job-protected leave for employees who have been employed for at least 13 consecutive weeks and have a serious medical condition confirmed by a physician. A medical certificate is required to access this protection. Our post on how long you can be on sick leave in Canada covers the full framework across all layers including EI sickness benefits and long-term disability in detail.
