ODSP Disability Determination Package: How to Fill It Out

What is inside the Disability Determination Package?

Ontario’s current professional guide describes six parts: two mandatory medical forms, two applicant forms that Ontario recommends or requires for a complete file, and separate instructions for the applicant and health professional. Read the instructions before writing in the package; they explain who can complete each section and how paper or digital submission works.

Both the HSR and ADLI must be completed. A single eligible professional may fill out both, or two professionals may complete them separately. If the sections are split, each professional signs and dates their own work. The paper package also includes instructions; keep them with the forms until every section has been checked.

Before the appointment: build a one-page timeline

A short, accurate chronology helps the professional understand a complicated record. Start with the approximate onset of the main conditions or symptoms. Add major investigations, diagnoses, hospital visits, specialist assessments, treatments, medication changes, rehabilitation and periods of worsening or improvement. Include only dates and events that make the disability story easier to follow.

Next, list the providers who hold useful records. Note which reports you already have and which may need to be requested. Ask the completing office what it can access. Do not assume that records move automatically between a hospital, specialist, therapist and community clinic.

Finally, write the submission deadline at the top. Work backward to allow time for the appointment, follow-up questions, missing reports, signatures, your Self Report and delivery. A package that reaches the right professional on day 85 is already in trouble.

How to prepare for the Health Status Report

The HSR should identify the conditions and the impairments they cause. Bring an up-to-date medication list, treatment history, available specialist or hospital reports and relevant test results. Tell the professional about treatment response, side effects, barriers to treatment and any important investigations still underway. Accuracy matters more than sounding severe.

Duration is important. Ontario’s legal test refers to a substantial impairment that is continuous or recurrent and expected to last one year or more. The professional should address when the impairment began, whether it is ongoing or episodic, and its expected course within the limits of their knowledge. “Unknown” may be honest in some cases, but unexplained blanks can delay a file.

Multiple conditions should be considered together. A person may have pain, fatigue, anxiety, cognitive symptoms and medication effects that interact even when no single item tells the whole story. Give the professional a concise list and explain which providers have supporting records. The adjudicator needs a coherent account of the direct and cumulative effects.

How to prepare for the ADLI

The ADLI translates health information into function. Avoid labels without examples. “Limited mobility” is less useful than a description of how far a person can walk, whether they need an aid or another person, how often they must stop and how long recovery takes. “Poor concentration” becomes more meaningful when tied to missed steps, inability to finish a short task, repeated instructions or the amount of supervision required.

Relevant activities may involve personal care, preparing food, cleaning, transportation, communication, remembering appointments, handling change, being around other people, completing work-like tasks or leaving home. Not every activity applies to every person. Choose examples that accurately show the restrictions caused by the documented impairments.

How to write the Self Report

The Self Report is where the applicant can connect the clinical record to daily life. Write in plain language. Use first-person examples and include frequency. If someone else helps write or type, the content should still reflect the applicant’s experience. Do not simply copy the professional’s section.

A useful paragraph often follows the same functional structure: “Because of [symptom or impairment], I have difficulty with [activity]. I can usually do it for [time or distance] before [what happens]. I need [type of help]. This occurs [frequency], and afterward [recovery or consequence].” The form is not a test of elegant writing. It is a place for concrete information.

Describe variability honestly. If you can complete a task on some days, explain how often those days happen, whether the task is reliable and repeatable, and what it costs afterward. If an activity is possible only because another person prompts, transports or assists you, include that support. The presence of help does not erase the underlying restriction.

Supporting evidence: choose relevance over volume

Ontario encourages professionals to include supporting medical information that clarifies the forms. Useful material may include specialist consultations, psychological assessments, occupational therapy reports, hospital summaries, relevant imaging or laboratory results and focused clinical notes. The evidence should support the conditions, duration or restrictions described.

More pages are not automatically better. A large record without explanation can hide the important evidence. Ask the professional which reports are most relevant and whether they can attach them to a digital submission. If sending paper, follow the package instructions about originals and copies.

Evidence can also explain why treatment is limited. Cost, side effects, wait lists, lack of a family doctor, transportation, trauma or another disability may affect access. Do not turn a treatment gap into speculation; document the real barrier and any efforts made to obtain care.

Who signs the medical sections?

Ontario permits physicians, optometrists, psychologists, psychological associates, nurse practitioners and registered nurses to complete both the HSR and ADLI. Chiropractors, physiotherapists, occupational therapists, social workers, audiologists and speech-language pathologists may also complete the ADLI. The professional must be licensed in Ontario.

Paper versus digital submission

Health professionals can submit the digital DDP through Ontario’s SADIE service. The digital route includes completeness checks and can accept supporting documents. With the paper route, Ontario says the applicant is responsible for mailing the completed package to the Disability Adjudication Unit using the addressed envelope, and original forms are required.

Decide the submission route with the professional. Confirm whether the Self Report and consent will be uploaded or mailed, who will submit the final package and how receipt will be documented. Keep copies of completed material where permitted. Do not send medical information to an unofficial email or upload it to a general contact form.

Final DDP checklist

If the deadline is close

Contact the Disability Adjudication Unit immediately. Ontario’s current page lists 1-888-256-6758 as the toll-free number and states that the applicant can ask for an extension. Explain the reason, the appointment or record date you are waiting for and how much additional time is needed. Record the call and any instructions.

Do not submit an incomplete package solely because the date is approaching without first asking about options. At the same time, do not assume an extension has been granted until you receive a clear answer. If disability affects communication, ask about accessible service or have an authorized support person assist.

Common DDP mistakes and how to correct them

The diagnosis is listed, but the impairment is not explained

A diagnostic label does not automatically show severity or function. Ask the professional to identify the physical, cognitive, psychological, sensory or communication impairments produced by the condition and connect those impairments to the ADLI restrictions.

The package describes only a single “good” appointment

Chronic and recurrent conditions can fluctuate. The forms should explain the overall pattern: frequency of episodes, duration, triggers where known, recovery and the degree of reliability between episodes. This is different from choosing only the worst day.

Different sections appear to contradict one another

Review the HSR, ADLI and Self Report for genuine inconsistencies. A difference may be explainable—for example, a task can sometimes be completed with help but not independently or repeatedly. Clarify the condition rather than forcing every sentence to use identical words.

There is no explanation of treatment barriers

A missing treatment does not always mean symptoms are mild. Cost, adverse effects, pregnancy, transportation, long wait lists, lack of an appropriate provider or another medical condition may be relevant. Document the actual barrier and the attempts made without speculating.

The form relies on vague words

Words such as “occasionally,” “limited,” “poor” or “difficult” can mean different things. Add frequency, time, distance, assistance, safety risk, after-effects or a concrete example. Precision makes the package easier to assess.

The paper forms were copied instead of submitted as originals

Ontario states that original paper forms are required when using the paper route. Keep photocopies for your records, but confirm that the signed originals are in the addressed envelope. Digital submission through SADIE follows a different process.

What happens after the package is sent?

Keep the proof of submission with your application timeline. Watch for mail and calls from the Disability Adjudication Unit or your caseworker. The unit may request additional medical information from the professional, so make sure the office has current contact details and knows to respond.

Ontario’s broader ODSP page explains that disability adjudication follows the financial stage for most applicants. Processing time can vary with completeness and follow-up. If you move, change phone numbers or lose access to an email address, update the program promptly and record the change.

When the decision arrives, read every page. A positive decision may include a medical-review date. A negative decision should explain review rights. Mark any deadline immediately. The free legal help guide explains community legal clinics, internal reviews and SBT appeals.
