Can You Combine the Disability Tax Credit with OAP Funding?
Direct answer
Yes, you can combine the Disability Tax Credit with OAP funding because the programs use separate eligibility rules. The CRA states that receiving other federal or provincial benefits does not affect DTC eligibility, while Ontario bases OAP registration on age, Ontario residence, and a written autism diagnosis. Neither program's rules exclude the other.

What this means for your family
Apply to each program on its own terms, since CRA and Ontario each run separate eligibility tests and neither one waits on the other's decision. Do not assume an autism diagnosis by itself qualifies your child for the Disability Tax Credit, because a medical practitioner still has to complete the impairment section of the application form describing its actual effects. Ask a doctor, nurse practitioner, or psychologist to complete that section rather than assuming any diagnosing professional can sign off on it. Once the credit is approved, look at what it opens beyond the tax return itself: eligibility for the Canada Disability Benefit, the Child Disability Benefit, a Registered Disability Savings Plan, and related savings grants and bonds, each with its own conditions. If your family already receives the Canada Child Benefit for that child, you do not need a separate application for the disability-linked child benefit. Keep a copy of everything you submit, since CRA can ask for more information before issuing a decision.

How the eligibility rules fit together
- CRA states that Disability Tax Credit eligibility is not affected by receiving other federal or provincial benefits. A family's receipt of Ontario Autism Program support therefore does not determine whether the child meets the federal DTC test.
- Ontario separately says that OAP registration requires the child to be under age 18, currently live in Ontario, and have a written autism diagnosis from a qualified professional. Each program must be assessed under its own published requirements.
What DTC approval can lead to
- Department of Finance Canada states that DTC eligibility is required for access to the Canada Disability Benefit, the Child Disability Benefit, a Registered Disability Savings Plan, and the Canada Disability Savings Grant and Bond. Each support also has its own additional conditions.
- For July 2026 through June 2027, the Child Disability Benefit is up to $3,480, or $290 per month, for each DTC-eligible child. A family already receiving the Canada Child Benefit for that child does not submit a separate Child Disability Benefit application.
Applying for the Disability Tax Credit
- An autism diagnosis alone does not establish DTC eligibility. CRA assesses the effects of the impairment, and a medical practitioner must complete Part B of Form T2201. Doctors, nurse practitioners, and psychologists are among the practitioners who can certify impairment effects for a DTC application.
- CRA's 2026 to 2027 service standard aims to issue a notice of determination within eight weeks, although the standard does not apply when more information is needed. An eligible person who did not claim the DTC in earlier years may be able to claim it going back up to 10 years.
Frequently asked questions
CRA states that DTC eligibility is not affected by receiving other federal or provincial benefits. Ontario separately lists age, Ontario residence, and a written autism diagnosis as the requirements for OAP registration.
No. CRA states that DTC eligibility is not based solely on the medical condition. It is based on the effects of the impairment, which a medical practitioner describes in Part B of Form T2201.
Submit Form T2201. The applicant completes Part A, and a medical practitioner completes Part B and certifies the severe and prolonged impairment.
For July 2026 through June 2027, the maximum is $3,480, or $290 per month, for each DTC-eligible child. The family must also be eligible for the Canada Child Benefit.
