Key takeaways
  • An extended society care order lasts until the court ends it or it expires, and every Part V order expires when the child turns 18 or marries, whichever comes first.
  • Under extended society care, the child stays in the care of the Children's Aid Society until a judge changes the order, the child is adopted, or the child turns 18.
  • What supports a youth can receive after 18 depends on the youth's circumstances and the society, so it is worth asking early and in writing.

Turning 18 can feel like a cliff for a youth who has been in the care of a children's aid society. Housing, school, money and support people can all change at once. Many youth want to know what help is still available.

This article explains how extended society care works under Ontario's Child, Youth and Family Services Act, 2017 (CYFSA) and what changes at 18. Voluntary supports for older youth depend on individual eligibility and on the agreement offered, so the article tells you what to ask rather than promising what you will get.

What extended society care is

When a court finds a child in need of protection, it can make several kinds of order, including supervision, an interim society care order of up to 12 months, or an extended society care order. Extended society care is the longest-lasting option.

An extended society care order lasts until the court terminates it under section 116 or it expires under section 123. In practice, the child stays in the care of the Children's Aid Society until a judge changes the order, the child is adopted, or the child turns 18.

What changes when you turn 18

Under section 123, every order under Part V of the CYFSA expires when the child turns 18 or marries, whichever comes first. That means the court order that placed you in society care ends at that point.

The end of the court order is not necessarily the end of all support. Whether a society offers a voluntary agreement or other services to a youth over 18 depends on the youth's history, needs and the society's requirements. Because those details can vary, ask your worker about options well before your birthday.

Things you can do before 18

The court must end an access order for a child in extended society care once it is no longer in the child's best interests. If the child has been placed for adoption and still lives with that family, no access application can be made.

Asking about supports after 18

Every order under Part V of the Child, Youth and Family Services Act expires when the child turns 18 or marries, whichever comes first, so any supports after that point are not part of a court order under that Part. The terms, length and eligibility rules depend on the program, so do not assume that a friend's arrangement will match yours.

Useful questions to ask your worker include: What services can I get after 18? What do I need to do to qualify? How long would an agreement last? What happens if I move, change schools or want to end it? Ask for the answers in writing, and ask who to contact if you disagree with a decision.

What to do next

Frequently asked questions

Does extended society care continue after I turn 18?

The court order does not. Every order under Part V expires when the child turns 18 or marries, whichever comes first. Any later support would come through a separate arrangement, so ask your society about it.

Can I leave extended society care before 18?

An extended society care order lasts until the court terminates it or it expires. A lawyer can explain whether that is realistic for you.

Can I still see my family if I am in extended society care?

Existing access orders end when extended society care is ordered, but the court can make or vary access if it is in the child's best interests. It must consider whether the relationship is beneficial and meaningful and whether access will impair adoption opportunities.

What if I disagree with a society decision?

You can make a formal written complaint, which the society must have an internal panel review. You can also ask the Child and Family Services Review Board to review the decision, or complain to the Ontario Ombudsman.
