What should an employer or HR team know about an ADHD diagnosis letter?

A diagnosis letter is evidence, not an employment decision

An ADHD diagnosis letter can support a disability-related request, but you still need to understand what the employee needs at work.

Where ADHD has been diagnosed, the letter records that clinical finding. Read its actual wording: a standard diagnosis letter is not a full assessment report and may not describe work-related limitations. The diagnosis alone does not establish how someone performs or which working arrangement is necessary.

Request information tied to essential job duties

Ask for the missing information that matters to the job, not the employee's whole medical history. Functional limitations describe how a health condition affects particular tasks or working conditions.

Ontario Human Rights Commission guidance generally focuses accommodation documentation on limitations and needs rather than a diagnosis or treatment history. More detailed disclosure needs a clear connection to the accommodation request. Confirm the requirements governing your workplace.

• Describe the essential duties and working conditions so the clinician can address relevant demands.
• Ask which tasks or conditions create disability-related barriers, and what the employee remains able to do.
• Ask about restrictions or supports needed, such as written task priorities or protected concentration time.
• Ask how long the need is expected to last and whether a review date is clinically appropriate.

Explain why clarification is needed. A standard diagnosis letter may not answer these questions, and a healthcare-provider report is not automatically necessary. Ask whether focused clarification is available before requesting a custom workplace form.

Accommodation duties depend on the employer's jurisdiction

Consider the request individually under the human rights law that applies to your employer.

Most workplaces are subject to provincial or territorial human rights law. Federally regulated workplaces, such as banks and airlines, fall under the Canadian Human Rights Act. Do not apply one province's rules to every workplace.

In Ontario, the Human Rights Code requires disability accommodation to the point of undue hardship. The Ontario Human Rights Commission identifies cost, outside sources of funding, and health and safety as the undue-hardship factors. Inconvenience or a colleague's dislike of an arrangement is not enough.

1. Discuss the actual barriers and possible adjustments with the employee.
2. Consider effective options rather than approving or rejecting a request solely because it names ADHD.
3. Record agreed supports, responsibilities and a review date. If information is pending, consider workable interim measures.
4. Explain any refusal with reasons and the alternatives considered. Get jurisdiction-specific advice before a disputed decision.

The duty is to provide an effective, appropriate accommodation, not necessarily the employee's preferred option.

Verify the issuer and restrict access to medical details

You can check who issued a letter without asking for unrelated medical details.

1. Review the employee's name, document date, author, professional designation and signature. Ask about missing or unclear details rather than assuming the document is invalid.
2. Check the author's registration with the relevant provincial professional regulator. For an Ontario nurse practitioner, use the College of Nurses of Ontario's Find a Nurse public register.
3. Obtain contact details from Finding Focus's official website to establish a contact route independently. Do not rely only on a telephone number, link or QR code printed on a questionable document.
4. With the employee's specific consent, ask whether the issuer produced the dated document. Limit the request to authenticity unless further disclosure has been authorized.

A register check confirms registration details, not the authenticity of an individual letter. Giving you a letter does not give the clinic blanket permission to release a chart or discuss care.

The Office of the Privacy Commissioner of Canada's workplace guidance emphasizes limited collection, appropriate access and safeguards. Applicable privacy law varies by sector and province. Store medical documents securely, separately from routine personnel or performance files.

Managers generally need the agreed adjustments and relevant restrictions, not the diagnosis. Do not disclose the diagnosis to colleagues to explain an accommodation.

Finding Focus documents have a defined clinical purpose

Choose documentation for the question you need answered, rather than defaulting to a full clinical report.

Finding Focus assessments are conducted virtually by independent, licensed Canadian nurse practitioners working with Finding Focus, using DSM-5-TR criteria and CADDRA-aligned practice. The assessment provides results and a treatment plan. An assessment can conclude that ADHD is not present.

A standard diagnosis letter is $49 and a healthcare-provider report is $99, both on request and priced separately from the assessment. For report details, obtain contact details from Finding Focus's official website.

Other care is separate from HR documentation. For adults, optional ongoing care is available by check-in. Therapy is available to adults 18+ physically located in Ontario through a Registered Social Worker. The therapist does not diagnose, perform psychological testing or write third-party reports.

Finding Focus does not make employment decisions and cannot promise that an employer will accept a document or approve a particular request. Do not assume custom workplace forms or occupational-health opinions are included. Confirm that a request is within the clinician's scope and the service offered.

A letter does not transfer care or certify fitness

Receiving a report does not, by itself, make another clinician responsible for care. Outside clinicians decide independently whether to accept any handover. Finding Focus does not assume another professional has accepted care because a report was sent.

Medication is managed by the prescribing clinician, not HR. Potential benefits and adverse effects of stimulant medications or non-stimulant options need individual review and monitoring, as outlined in the Centre for Addiction and Mental Health's clinical guidance. The therapist does not prescribe or adjust medication.

For clinical continuity questions, obtain contact details from Finding Focus's official website.

Do not treat a standard diagnosis letter as a job-specific fitness-for-duty opinion, particularly for safety-sensitive duties. If that is the question, use an appropriate occupational-health process and ask what assessment is needed. Do not infer that someone is unsafe simply because the letter names ADHD.
