It is the gateway to a non-refundable disability credit and, for children under 18, to the **Child Disability Benefit** — a tax-free supplement paid monthly through the **Canada Child Benefit**. For Quebec families dealing with separation, the certificate matters beyond tax filing. The disability amount can be transferred to a supporting parent, and the Child Disability Benefit flows to whichever parent the Canada Revenue Agency recognizes as the eligible individual. Both entitlements affect child support calculations and become contested in settlement negotiations. Consult the [Canada Revenue Agency (CRA) guide on disability-related tax measures](https://www.canada.ca/content/dam/cra-arc/formspubs/pub/rc4064/rc4064-25e.pdf) for comprehensive information. ## What Does the Disability Tax Credit Certificate Do? Filing the certificate initiates a formal assessment by the Canada Revenue Agency, which reviews the medical information certified by a qualified practitioner and issues a **notice of determination**. The form operates under [sections 118.3 and 118.4 of the _Income Tax Act_](https://canlii.ca/t/7vb7#sec118.3subsec1), defining severe and prolonged impairment and the conditions for claiming the disability amount. When approved for a child, the disability amount can be claimed by the parent or another supporting family member. Approval triggers the **Child Disability Benefit** (a tax-free payment of up to approximately $300 per month, indexed annually) and opens access to the **Registered Disability Savings Plan (RDSP)**, which attracts federal matching grants of up to approximately $3,500 per year. > ⚠️ The certificate does not itself grant the credit. It is the application form that triggers CRA's review process. If approved, CRA issues a notice of determination confirming eligibility. The disability tax credit itself (up to approximately $10,000 annually for individuals) can be claimed on your tax return and carried forward. For children under 18 who qualify, an additional approximately $6,000 supplement applies. The Child Disability Benefit and RDSP access follow upon approval. ## When Do You Need the Disability Tax Credit Certificate? File when your child has, or is expected to have, a severe and prolonged impairment in vision, speaking, hearing, walking, eliminating, feeding, dressing, or mental functions necessary for everyday life. The impairment must have lasted, or be expected to last, at least 12 consecutive months. The certificate is also required when your child needs **life-sustaining therapy** at least twice weekly for an average of 14 hours per week. Children diagnosed with **type 1 diabetes** in 2021 or later automatically meet the life-sustaining therapy criteria. Where no single impairment reaches the threshold, the child may qualify through cumulative significant limitations across two or more categories. > ⚠️ Eligibility is based on functional limitation, not diagnosis alone. A qualifying diagnosis may be denied if the practitioner does not demonstrate the required severity. ## Who Must File the Disability Tax Credit Certificate? **Part A** is completed by the child's parent or legal guardian — identifying information, the supporting family member intending to claim the disability amount, and authorization for the Canada Revenue Agency to contact the practitioner. The parent or guardian must sign; without that signature, the form will not be processed. **Part B** is completed by a qualified medical practitioner. Medical doctors and nurse practitioners can certify all categories; other authorized practitioners — including optometrists, audiologists, psychologists, and therapists — are limited to specific types. > ⚠️ If both parents intend to split the disability amount, include both sets of details in section 2 of Part A. ## How Do You Use the Disability Tax Credit Certificate? Complete Part A with the child's information and supporting family member details. To have prior tax returns adjusted upon approval, indicate this in section 3. Then have the treating practitioner complete Part B — a digital application is available through the agency's online portal. Submit by uploading a scan through the [CRA account login](https://www.canada.ca/en/revenue-agency/services/e-services/cra-login-services.html), or by mailing the paper form to the Jonquière Tax Centre, 2251 René-Lévesque Blvd, Jonquière QC G7S 5J2. Keep a copy for your records. > ⚠️ Submit the certificate before filing your annual tax return. Claiming the credit before approval may delay your assessment. ## Required Documents and Information - **Part A signed**: child's and supporting family member's personal information, including social insurance numbers - **Part B certified**: clinical information on the child's impairment, year of onset, and prognosis - **Medical records**: diagnostic test results, treatment notes, and specialist reports - **Legal authority**: required only if someone other than the parent is filing > ⚠️ The practitioner may charge a fee for completing Part B; this may be claimable as a medical expense on your tax return (see lines 33099 / 33199). ## What Are the Processing Times and Fees? There is no government fee. The CRA's service standard is eight weeks from receipt of a complete application, though complex cases and backlogs can extend this. Track your application through [CRA My Account](https://www.canada.ca/en/revenue-agency/services/e-services/cra-login-services.html). If denied, you may request a review with additional documentation or file a formal objection within 90 days. > ⚠️ Do not assume approval when making financial commitments tied to the credit or the Child Disability Benefit. ## How Does the Disability Tax Credit Certificate Affect Family Law Matters? ### Who Claims the Disability Amount The child supplement is reduced when child care or attendant care expenses are claimed beyond a threshold. In separation, this creates a direct interaction between the parent claiming child care deductions and the parent claiming the disability amount — both allocations should be addressed together in the agreement. In shared custody, both parents may agree — or a court may order — how the credit is allocated. ### Effect on Child Support The Child Disability Benefit is included in the income used to determine support under Quebec's [_Regulation respecting the determination of child support payments_](https://canlii.ca/t/10pq). A child's disability may also extend the obligation to pay child support beyond the age of majority. Under [article 585 of the _Civil Code of Québec_](https://canlii.ca/t/z35#TITLE_THREE_OBLIGATION_OF_SUPPORT_1143194), parents owe support to their children without any age limit, and [article 587 of the _Civil Code of Québec_](https://canlii.ca/t/z35#se:587) allows the court to fix that support based on the child's needs and the parents' means. Where a child is unable to become financially autonomous due to a disability, support may continue well past age 18. For disabled adults aged 18–64, DTC approval may also open access to the Canada Disability Benefit, which is income-tested and may affect spousal support calculations. ### The Registered Disability Savings Plan Approval of the certificate is the prerequisite for opening a Registered Disability Savings Plan, which attracts federal grants of up to $3,500 per year. Family law practitioners in Montreal routinely advise separating parents to address the plan's management as part of their agreement. > ⚠️ A separation agreement that omits disability amount allocation, Child Disability Benefit designation, and Registered Disability Savings Plan management leaves all three open to dispute. ## Illustrative Scenario > 📌 **Parent A** and **Parent B** share custody of their eight-year-old child, diagnosed with autism spectrum disorder in Montreal at age four. **Parent A** is the primary caregiver and receives the Canada Child Benefit. **Parent B** has the higher income and has been claiming the disability amount informally. When **Parent A** and **Parent B** formalize their separation, who claims the disability amount and who receives the Child Disability Benefit must be resolved. **Parent A** argues the benefit flows automatically as the eligible individual. **Parent B** wants the disability amount because the tax savings are greater against their higher income. Their attorney drafts a clause: **Parent B** claims the disability amount, **Parent A** receives the Child Disability Benefit, and both contribute to the child's Registered Disability Savings Plan. Without this, each parent's filings would conflict, triggering reassessments and repayment demands. ## Frequently Asked Questions ### Can both parents receive the Child Disability Benefit in shared custody? Yes. In shared custody, the Canada Revenue Agency splits the Canada Child Benefit — including the Child Disability Benefit — equally between parents. Each receives 50% calculated against their own adjusted family net income once both notify the agency. ### Does disability tax credit approval expire? Yes, but not always. The notice of determination specifies an eligibility period. Some approvals are indefinite; others have an end date tied to the practitioner's prognosis. When the period expires, a new certificate is required. ### Can I apply retroactively if my child was diagnosed years ago? Yes. Indicate in Part A that you want prior returns adjusted. Upon approval, the agency reassesses applicable years going back up to ten years, and retroactive Child Disability Benefit payments are calculated automatically. ## Common Mistakes to Avoid - **An incomplete Part B.** Practitioners who describe the diagnosis without explaining its functional impact leave the agency without the information it needs. The form asks whether the child takes three times longer than a child of similar age — the practitioner must answer directly. - **Separating parents who fail to coordinate filings create a second problem.** If both claim the disability amount without an agreement specifying entitlement, the agency reassesses one or both returns — a clear allocation clause prevents this. - **Accepting an initial denial without exploring the cumulative effect pathway.** When no single impairment meets the marked restriction threshold, two or more significant limitations may combine to establish eligibility — a route many families overlook. ## When to Get Legal Help The certificate is a federal tax form, but its consequences reach into Quebec family law. If you are separating and your child has a qualifying disability, consult a family law attorney before filing to ensure the agreement addresses disability amount allocation, Child Disability Benefit designation, and Registered Disability Savings Plan management. Where a child's disability may extend support beyond 18 or affect net income in support calculations, professional guidance is essential. These questions have lasting financial consequences for the entire family. ## Speak with a Family Lawyer Separated parents often disagree about how to allocate the disability tax credit, the Child Disability Benefit, and the Registered Disability Savings Plan. These are not merely tax questions — they are family law issues that must be resolved in your separation agreement or court order. A misalignment between what you file with the CRA and what your agreement specifies creates reassessment exposure and ongoing conflict.
