Do You Need Custody to Claim the Canada Child Benefit as a Grandparent?

It's one of the first questions every kinship caregiver asks: do I need to go to court before I can claim the Canada Child Benefit for this child? The short answer is no. The CRA cares about who is actually providing daily care, not whether you have a piece of paper from a judge.

How the CRA Decides Who Gets the CCB

Under Section 122.6 of the Income Tax Act, the Canada Child Benefit goes to the person who is "primarily responsible for the care and upbringing" of the child. That's a factual test, not a legal one. The CRA looks at who is doing the actual work of raising the child day to day:

• Who supervises the child's meals, bedtime, and daily routine?
• Who enrolled the child in school and is listed as the emergency contact?
• Who takes the child to medical and dental appointments?
• Who arranges childcare, extracurriculars, and community activities?
• Who provides the child's physical shelter, clothing, and food?

If the answer to these questions is you — the grandparent, aunt, uncle, or other relative — you can claim the CCB regardless of whether you have a custody order, a guardianship appointment, or any court involvement at all.

What You Need Instead of a Court Order

Without a court order, the CRA relies on third-party evidence to verify that you're the primary caregiver. This is especially important if the child's biological parent was previously receiving the CCB, because the CRA needs to transfer the benefit from one person to another.

Strong evidence includes:

• School enrollment records showing the child's address as your address and you as the parent or guardian contact
• A letter from the child's school confirming you handle enrollment, pickup, and school communications
• Medical records showing you as the person who books and attends appointments
• A letter from a doctor or nurse practitioner confirming you bring the child to medical visits
• Daycare or childcare records naming you as the responsible adult
• A letter from a social worker, band council representative, or community leader confirming the child lives with you

The more evidence you can provide from different sources, the stronger your application. Our detailed guide on proving primary care responsibility to the CRA covers exactly what the CRA accepts and how to request these letters.

When a Court Order Does Help

Even though you don't need a court order for the CCB, there are situations where having one makes things smoother — or is necessary for other reasons:

The biological parent disputes your claim. When you apply for the CCB and the parent was the previous recipient, the CRA may contact both parties to confirm who is providing primary care. If the parent disputes your claim, the CRA assesses the evidence. A court order that clearly addresses the child's residence or caregiving arrangement can support your application, but the CRA still decides who is primarily responsible based on the facts.

You need authority for medical or educational decisions. The CCB is a financial benefit, but daily life with a child involves consenting to medical treatment, signing school forms, and making decisions that some institutions won't accept from anyone other than a parent or legal guardian. A parenting order or guardianship order gives you the legal standing to make these decisions without relying on the biological parent's cooperation.

A Children's Aid Society is involved. If the child came to you through the child welfare system, a court order may already be part of the arrangement — or the agency may be working toward one. In these cases, the legal framework affects not just the CCB but the entire support structure. If the child is formally "in care" under a Children's Aid Society, the agency receives the Children's Special Allowances instead, and you can't claim CCB until the child transitions out of agency care.

You want long-term security. If the child's situation is stable and they'll be with you for years, a court order provides protection against the parent showing up and removing the child. That peace of mind may be worth the legal process, separate from any benefit considerations.

The Practical Path for Most Kinship Caregivers

Most grandparents and relatives raising a child follow this sequence:

1. Apply for the CCB first — submit Form RC66 with your evidence of primary care. This starts the application process. The CRA's 2026–2027 service standards are 8 weeks online or 11 weeks by mail for complete applications.
2. Build your evidence file — collect letters from the school, doctor, and any other third parties who can confirm the child lives with you. This protects you if the CRA sends a benefit review letter.
3. Consider legal advice separately — if you decide you want a formal custody or guardianship order, legal aid can help. But don't wait for the court process before applying for the CCB — the two timelines are independent.

This approach gets financial support flowing as quickly as possible while you sort out the legal side at your own pace.

What Happens After You Apply

Once the CRA receives your RC66, it processes the application and may contact the previous claimant (typically the biological parent) to confirm that the child is no longer in their primary care. If the parent doesn't respond within 30 days or can't provide evidence that the child still lives with them, the CRA may transfer the benefit to you. Retroactive payments are generally limited to 11 months automatically; older periods require supporting documents and CRA approval, up to 10 years.

If the CRA requests additional documentation during a review, respond promptly with your evidence file. The stronger your third-party proof, the faster the process resolves.

Our complete guide walks through every step of this process — from the initial RC66 application through CRA reviews and formal objections — with the specific forms, evidence requirements, and timelines you need as a kinship caregiver.
