A Relative Is Caring for a Child in Ontario: What Legal Rights Do You Have?

You are an aunt, uncle, adult sibling, or close family relative, and a child has ended up in your care. Maybe a parent passed away. Maybe the parents are in crisis and you stepped in. Maybe the family asked you to take the child "just for a while" and months or years have gone by. Whatever brought you here, you are doing real, meaningful parenting work — and you may be wondering what legal standing you actually have.

The short answer is: relative caregivers in Ontario have legal rights, but those rights depend on what steps have been taken to formalize the arrangement. Informal care gives you moral authority, not legal authority. This article explains the difference and how to get the protection you and the child need.

Informal vs. Formal Care: Why It Matters

When a child lives with a relative on an informal basis — no court order, no formal agreement — the relative has no guaranteed legal rights. Specifically:

• The parents can take the child back at any moment, regardless of how long the child has been with you or how disruptive that removal would be.
• Institutions may not recognize your authority. Schools, hospitals, and government offices look for a parent or legal guardian to make decisions. Your biological relationship to the child does not substitute for legal standing.
• Disputes about the child's future cannot be resolved by you alone. If the parents disagree with a decision you want to make — or disagree with each other — you have no formal role in any legal proceeding unless you have a court order.

Formalizing your caregiving role protects the child's stability and gives you the authority to act in their best interests.

What Ontario Law Says About Relatives as Caregivers

Ontario's Children's Law Reform Act (CLRA) allows "any person" to apply for decision-making responsibility (the successor to what was once called "custody") or parenting time if they have a settled interest in the child's welfare. The law does not limit these applications to parents or grandparents.

This means that an aunt, uncle, adult sibling, or other relative who has meaningfully participated in a child's care can bring a court application for formal recognition of their role.

The governing standard is always the best interests of the child — and courts take a thorough look at:

• The length and nature of your caregiving relationship
• The child's emotional attachment to you
• The stability and quality of care you provide
• What the parents' situation is and whether they are willing or able to parent
• The child's own views (weighted according to age and maturity)

Options for Relatives Seeking Legal Recognition

Written Authorization From the Parent

If the parent is cooperative, they can give you written authorization to make decisions for the child during their absence. This is quick and costs nothing, but it is revocable at any time and may not satisfy all institutions.

A notarized letter is better than an unsigned one. For health care specifically, some hospitals have their own authorization forms that they prefer.

Consent Agreement Filed as a Court Order

If both parents agree that you should have a formal role, you can draft a consent agreement setting out your decision-making authority and parenting time. When this agreement is filed with the court and incorporated into an order, it has legal force — neither parent can simply revoke it without returning to court.

This is the fastest route to a legally binding arrangement when everyone is cooperative.

Contested Application Under the CLRA

If the parents are not cooperative — or if one parent is absent and the other disputes your role — you can apply to the court for an order. You will need to demonstrate:

• Your existing relationship with the child
• The circumstances that brought the child into your care
• Why an order granting you decision-making responsibility or parenting time serves the child's best interests

Courts do not give third-party applicants the same starting presumption they give parents. You will need solid evidence of your caregiving role and the child's attachment to you.

Children's Aid Society Kinship Placement

If the Children's Aid Society is involved, they may approach you as a potential kinship caregiver — placing the child with you formally while maintaining some oversight. Ask your CAS worker about kinship allowances and what legal steps can follow a kinship placement.

Evidence That Supports a Relative's Application

• School records listing you as the primary contact or emergency contact
• Medical records showing you attended appointments and consented to treatment
• Financial records showing you paid for the child's food, clothing, activities, and care
• Photographs and communications demonstrating the day-to-day relationship
• Letters from teachers, doctors, or community members who observed your caregiving
• A chronological account of how the child came to be in your care

Courts in Ontario weigh this kind of concrete evidence seriously. If you are currently in an informal caregiving arrangement, start documenting now even before any legal steps are taken.

What About the Parents' Rights?

A court order giving you decision-making responsibility does not automatically terminate the parents' legal relationship with their child. In most cases, parents retain parenting time or contact. An order defines your authority — it does not erase the parents from the picture.

However, if a parent's involvement would harm the child (for example, because of ongoing abuse, serious substance use, or a history of violence), the court can limit or suspend the parent's parenting time.
