Key takeaways
  • Relatives living in Ontario, such as grandparents, aunts and uncles, can apply directly to an Ontario court for an adoption order without an adoption licensee.
  • A practitioner homestudy is not required for relative adoption unless the judge requires it.
  • Adoption is a permanent court order, but other options such as legal custody or a parenting order may suit some families better.
  • If the relative lives abroad, the international adoption process applies instead.

If you are a grandparent, aunt, uncle or older sibling raising a relative's child, you may be wondering whether adoption is the right step. Perhaps the child already lives with you, but you cannot easily make decisions or you want the arrangement to be permanent.

Adoption is only one option. This article explains how relative adoption works in Ontario, how it differs from other kinship arrangements, and what to consider before you start. Your family's facts matter a great deal, so treat this as a map and not a substitute for advice.

Can a relative adopt directly?

Relatives living in Ontario, such as a niece, nephew, grandchild or stepchild, can apply directly to an Ontario court for an adoption order. No adoption licensee is needed, and no adoption practitioner homestudy is required unless the judge requires it. A lawyer may be needed, and the Law Society of Ontario can help you find one.

If the relative is abroad, the international adoption process applies instead. That process has its own requirements, including ministry approval before leaving Ontario.

This is different from public adoption through a children's aid society, which is for children in extended society care (formerly Crown wards). A child being raised by a relative may or may not be in that category, so it is worth finding out which route applies.

What an adoption order does

The adoption order makes the adopter the child's legal parent. It is a permanent court order. For many grandparents and other relatives, that permanence is the point. It also means a major change in the child's legal family, so it should be considered carefully with the child's circumstances in mind.

Consent matters. If the consent of someone who has not signed is needed, the applicant can bring a motion to dispense with it, and the respondent must serve and file an Answer (Form 10) to oppose. If they do not, the court may dispense with consent without further notice to them. Whether an unmarried birth father counts as a parent whose consent is needed depends on the facts, so ask a lawyer.

Other kinship options

Ontario describes several ways a relative can care for a child: a kinship service where the child stays out of society care with a relative, kinship care (a form of foster care), legal custody, adoption, or customary care for First Nations, Inuit and Métis children. Once a legal custody order is made, the child is no longer in society care.

Non-parents such as grandparents can also apply for a parenting order on decision-making responsibility or a contact order. Decision-making responsibility covers significant decisions about health, education and religion. The court must make an order in the child's best interests and consider family violence and current living arrangements.

Practical points to weigh

If the child is adopted through a children's aid society, post-adoption subsidies may be available, applied for through the society. The amounts depend on the child and on combined net family income, so check the current Ontario figures. Free post-adoption training (Pathways to Permanence 2) is available to families who adopt, or have a child placed with them, through a society. Whether these apply to a private relative adoption is something to confirm.

What to do next

Frequently asked questions

Do grandparents need a homestudy to adopt a grandchild?

Relatives living in Ontario can apply directly to an Ontario court, and no adoption practitioner homestudy is required unless the judge requires it. Your judge may still ask for more information, so be ready for that.

Do we need an adoption licensee for a relative adoption?

No. Relatives living in Ontario can apply to the court without an adoption licensee. A lawyer may still be needed.

Is adoption better than custody for a grandparent?

It depends on what you need. Adoption is a permanent court order that makes you the legal parent. A parenting order can give decision-making responsibility or contact without that change. A lawyer can compare them for your facts.

What if the child's parent does not agree?

If a needed consent has not been signed, the applicant can bring a motion to dispense with it, and the other person can oppose by filing an Answer (Form 10). The outcome depends on the facts, so get legal advice early.
