Short-Term Disability Doctor's Note: What Your STD Claim Actually Requires

A short-term disability claim rarely gets denied outright — it gets stuck. Insurers approve or delay a claim almost entirely based on what is written on the attending physician's statement, and a form that is vague about diagnosis, functional limitations, or an expected return-to-work date is the most common reason an STD file sits unopened in a claims queue for weeks. Most Canadian group insurers, including Manulife, Sun Life, and Canada Life, use their own proprietary physician statement rather than accepting a generic sick note, and submitting the wrong document, or one missing a required field, resets your processing timeline. This post covers exactly what a short-term disability doctor's note needs to say, who is allowed to complete it, how it differs from an everyday sick note, and what to do when your insurer comes back asking for more.
What short-term disability insurance actually covers
Short-term disability (STD) is an employer-sponsored group insurance benefit, not a government program — a distinction that surprises people who assume it works like Employment Insurance sickness benefits. Coverage typically replaces 60 to 70 percent of your regular salary, starts after an elimination period of five to seven business days during which you use sick days or go unpaid, and runs for a set window, commonly 15 to 26 weeks, before you either return to work or the claim transitions to long-term disability (LTD). The exact percentage paid, the elimination period, and the maximum duration all come from your specific group policy rather than any statute, so the first place to check is your plan booklet or group benefits portal, not a general guide like this one. What stays consistent across nearly every Canadian STD plan is the requirement for medical evidence, submitted on the insurer's own form, before a single payment goes out.
What a short-term disability doctor's note must include
A short-term disability doctor's note is not a one-line note. It is a structured attending physician statement, usually four to six pages, that the insurer requires a licensed physician to complete in detail. The exact fields vary by insurer, but the categories they ask for are consistent:
A specific diagnosis or clinical impression — insurers need a recognized medical diagnosis, not just a description of symptoms, to assess the claim against their own criteria.
The date your inability to work began — this anchors your elimination period and determines when payments start.
Objective functional limitations — a description of what you can and cannot physically or cognitively do, tied to the actual demands of your job rather than a general statement of illness.
Current treatment and prognosis — medications, therapy, specialist referrals, and how your treatment is expected to progress.
An expected or estimated return-to-work date — insurers accept "undetermined" if that is genuinely the case, but the form has to address the question rather than leave it blank.
The physician's licence number, signature, and contact information — insurers routinely follow up directly with the completing physician, and an incomplete signature block is a common reason forms are sent back.
Who can complete your short-term disability medical certificate
Most group insurance policies specify that the attending physician statement must be completed by a licensed physician, though a growing number of plans also accept nurse practitioners, particularly for primary care claims. Claims involving a mental health diagnosis are commonly supported by a psychiatrist or registered psychologist instead of, or alongside, a family physician. What matters to the insurer is not which type of clinic you visited but whether the person signing the form is licensed to diagnose and treat the condition described, and whether they have direct clinical knowledge of your case, whether through an ongoing relationship or a documented assessment.
How an STD doctor's note differs from a regular sick note
A sick note for a short absence is typically a single sentence confirming you were seen and are unfit for work on specific dates — enough for an employer's internal attendance record. An STD attending physician statement is a different category of document entirely: it is a claims form for an insurance company, built around the specific fields an adjudicator uses to approve or deny payment, and it usually needs to be renewed periodically for as long as the claim continues rather than filed once. Submitting a basic sick note in place of the insurer's actual physician statement form is one of the most common reasons an STD claim is rejected at intake, since the insurer has nothing to assess a benefit against.
Job protection during short-term disability leave, by province
STD itself is a private insurance benefit and is not regulated by any province, but the job protection running alongside your claim comes from employment standards legislation, and that part does vary:
Federally regulated employees — under the Canada Labour Code, workers at banks, airlines, telecoms, and other federally regulated employers get job-protected medical leave of up to 17 weeks, which runs concurrently with an STD claim of similar length.
British Columbia — the Employment Standards Act provides unpaid, job-protected leave for illness or injury of up to 27 weeks, covering most STD claim durations in full.
Ontario — the Employment Standards Act's own sick leave provision caps out at three unpaid days a year; job security through a longer STD claim depends on your employment contract and the employer's duty to accommodate under the Ontario Human Rights Code, not a dedicated ESA leave category.
Quebec — the Act respecting Labour Standards provides job-protected leave for illness, and claims arising from a workplace injury go through the CNESST instead of your group insurer.
Employment and Social Development Canada, which administers the Canada Labour Code, is the authoritative source for the federal 17-week figure. Confirm your own province's current threshold directly with its employment standards branch before relying on it for a specific claim, since these figures do change.
What happens if your insurer asks for more documentation
Insurers routinely request updated medical evidence partway through an STD claim, especially past the four-to-six-week mark, and some require a new attending physician statement every two to four weeks for the duration of the claim. A minority of claims are also referred for an independent medical examination, where a physician selected by the insurer, rather than your own doctor, assesses your condition. Responding quickly to these requests matters: benefits are commonly suspended, not cancelled, when documentation lapses, and reinstating a suspended claim afterward takes longer than keeping the paperwork current in the first place.
Getting your short-term disability doctor's note without losing a week to a waitlist
Because an insurer's attending physician statement is a specific, insurer-branded form rather than a generic template, completing it requires a physician willing to fill out that exact document — something a walk-in clinic squeezed for time will not always prioritize. That kind of insurer-specific paperwork is handled through our custom medical documentation service, where a licensed Canadian physician completes your plan's actual form rather than a generic substitute.
If your employer or plan instead uses one of the more common standardized attending physician statements, that is covered through our standard medical forms service.
And once your claim period ends, most employers ask for a fitness-to-work note before you resume your duties, which we handle through our fitness certificates service, so the transition back does not stall on paperwork a second time.
Frequently asked questions about short-term disability doctor's notes
Does my STD doctor's note need to name my exact diagnosis?
Almost always, yes. Unlike a basic sick note, an insurer's attending physician statement is built around adjudicating a specific medical diagnosis against plan criteria, and a form that only describes symptoms without a diagnosis is commonly returned as incomplete.
Can a nurse practitioner complete my short-term disability paperwork?
Many plans now accept a nurse practitioner's signature, particularly for primary care claims, but this depends on your specific policy. Check your plan booklet or ask your HR department before booking an appointment.
What if my insurer's form is not a plain doctor's note?
That is the norm, not the exception. Most Canadian STD plans use a proprietary attending physician statement several pages long, and a physician needs to complete that specific document rather than write a generic note.
How often do I need updated documentation during an STD claim?
It depends on your insurer, but many require a renewed statement every two to four weeks for the length of the claim, particularly past the first month.
What happens if my STD claim is denied for insufficient medical evidence?
Most insurers allow you to appeal by submitting additional or clarified medical documentation, and some claims that were initially denied are approved once a more complete attending physician statement is filed.
Can I get my short-term disability doctor's note completed online?
Yes. Canada Medical Notes connects you with a licensed Canadian physician who completes your insurer's specific attending physician statement and returns it to your inbox, typically within a few hours rather than after a days-long clinic wait.
