Can I use an ADHD diagnosis report to apply for an RDSP?

Not directly: an RDSP requires Disability Tax Credit approval, and the report feeds that application

A financial institution will not open an RDSP on the strength of a diagnosis report, because the report is not what the program checks. The Canada Revenue Agency describes the RDSP as a savings plan intended to help an individual who is approved to receive the disability tax credit save for long-term financial security, and Employment and Social Development Canada lists DTC approval as the first condition for opening a plan, alongside Canadian residency, a valid Social Insurance Number and applying before December 31 of the year the beneficiary turns 59.

The DTC, in turn, is decided by the CRA on Form T2201, the Disability Tax Credit Certificate, which a medical practitioner certifies. So the report from Finding Focus, whether the $49 standard diagnosis letter or the $99 healthcare-provider report listed on the pricing page, is two steps removed from the RDSP. It is useful, and often necessary, but only because it helps the practitioner completing the T2201 describe your impairment accurately. The Disability Tax Credit page covers that application in detail.

The sequence is report, T2201, CRA decision, then the plan

Each step depends on the one before it, and skipping ahead wastes time at the bank.

1. Obtain your assessment documentation. After a Finding Focus assessment, request the healthcare-provider report if it will be used to support a DTC application, since it describes functional impairment in more detail than the letter. The copy of your report page explains how to request it.
2. Have a medical practitioner complete Part B of Form T2201. The certifier describes the effects of the impairment on the mental functions the CRA lists. The CRA names nurse practitioners among the practitioners who can certify the form; confirm the current list on the CRA site, and ask the certifier whether they will use your report as part of their assessment.
3. Submit the T2201 to the CRA and wait for the decision. The CRA may approve for a fixed period or indefinitely, may ask the certifier for more information, or may decline. Only the CRA decides.
4. Open the RDSP at a participating financial institution once the notice of determination confirms DTC approval, and apply for the Canada Disability Savings Grant and Canada Disability Savings Bond at the same time if you are within the age limits.

The DTC tests marked restriction over time, not whether you have ADHD

The single most important fact for anyone with ADHD considering an RDSP is stated plainly by the CRA: eligibility for the DTC is based on the effects of an impairment, not a diagnosis. Under the mental functions category, the CRA describes three conditions that must all be met.

• A marked restriction: you are unable to perform mental functions necessary for everyday life, or it takes you three times longer than someone without the impairment, even with appropriate therapy, medication and devices.
• Present all or substantially all of the time, which the CRA describes as generally 90 per cent or more.
• Lasting, or expected to last, a continuous period of at least 12 months.

The mental functions the CRA lists include adaptive functioning, attention, concentration, goal-setting, judgment, memory, problem-solving, regulating behaviour and emotions, verbal and non-verbal comprehension, and perception of reality. Several of those overlap with what an ADHD assessment documents, which is why some people with ADHD are approved. But the phrase even with appropriate therapy, medication and devices means the CRA is asking about your functioning while treated, and a person whose ADHD is well managed on medication may not meet the marked restriction test. The CRA encourages people who are unsure to apply rather than self-assess, and Income Tax Folio S1-F1-C2 sets out the legal interpretation of these provisions for anyone who wants the technical detail.

A report helps the certifier when it documents function, not just the diagnosis

The certifier completing the T2201 is asked to describe effects, so a report that only confirms a diagnosis gives them little to work with. The healthcare-provider report from Finding Focus is more useful for this purpose because it records what the assessing clinician observed and documented across the domains the CRA asks about.

• How the assessment was conducted: a video assessment by a licensed nurse practitioner or clinician working with Finding Focus, applying DSM-5-TR criteria and CADDRA-aligned practice.
• Which symptom domains were present and with what severity, in the clinician's words.
• Documented functional impact on daily life, work or study, including time taken to complete ordinary tasks where that was recorded.
• Treatment to date and the response to it, since the CRA test applies with treatment in place.
• Duration: when symptoms began and how long the current level of impairment has persisted.

If the report is more than a year old, or if treatment has changed since it was written, a follow-up visit at $74.99 per check-in without membership lets the clinician update the functional description before it goes to the certifier. A report cannot state whether you will qualify, and neither the clinic nor the certifier controls the outcome. An assessment can also conclude that a person does not have ADHD, in which case the RDSP question does not arise on that basis.

Once the DTC is approved, the RDSP carries age limits, grants and a benefits protection worth knowing

The practical value of the plan depends on age and income, and the government pages state the limits precisely.

Contribution limits, grant rates and bond amounts are set by the federal program and change over time, so use the current CRA and ESDC pages rather than any summary when you plan. Insurance reimbursement for the assessment itself is a separate question, covered on the insurance reimbursement page, and is unrelated to DTC or RDSP eligibility.
