Turning 18 doesn't have to mean the support of a Children's Aid Society ends the same day. Ontario has options for young people leaving care to keep receiving help while they finish school, find stable housing, or get on their feet — but accessing those supports generally means planning ahead, not waiting until the day arrives.

This guide explains, in general terms, what aging out of CAS care means legally, and what to ask about well before you turn 18.

What "Aging Out" Means

The legal responsibility a Children's Aid Society holds for a child in its care — for example, a child in extended society care — is generally tied to that person being a minor. Turning 18 changes that legal relationship. It doesn't have to mean support ends abruptly, though, since Ontario has continued-support options for eligible young adults leaving care. Exactly what's available, and for how long, depends on your specific circumstances and should be confirmed directly with your Society well in advance.

Start Planning Before You Turn 18

What Kinds of Support May Be Available

Exact eligibility rules, and how long support remains available, change and should be confirmed directly with your Children's Aid Society or a lawyer well before you turn 18 — don't rely on a general description like this one for your specific timeline.

If You're a Parent or Caregiver Supporting a Youth Through This Transition

Parents, foster parents, and kinship caregivers often play an important role in helping a young person navigate this period, even where the Society's legal responsibility is changing. Practical ways to help include keeping copies of important paperwork together in one place, encouraging the youth to ask questions of their worker directly rather than assuming someone else will, and helping them understand that accepting continued support is generally their own choice to make once they're an adult — not something that happens automatically, and not something anyone else can decide for them.

Your Legal Rights Don't Disappear at 18

As an adult, you gain the right to make your own decisions about accepting or declining continued support, accessing your own records, and seeking legal advice on your own behalf — including about any past court orders that affected you while you were a minor.

Common Gaps Worth Watching For

Transitions between systems are where support most often falls through the cracks. It's worth specifically checking on:

Raising these questions early — rather than after a gap has already occurred — is generally the difference between a smooth transition and a stressful one.

Frequently asked questions

Does all CAS support automatically stop the day I turn 18?

Not necessarily. Ontario has options to continue support for eligible young adults leaving care, but they generally need to be arranged rather than assumed — ask your worker well in advance of your birthday.

Can I ask to see my own CAS file once I'm 18?

As an adult, you generally have the right to request access to your own records. Ask the Society what its specific process is for a youth requesting their file.

What if I already turned 18 and didn't ask about continued support?

Contact your former Children's Aid Society or a family lawyer to ask what options may still be available. Don't assume it's automatically too late — ask directly.

Do I need a lawyer to access continued support?

Not necessarily to access standard supports, but a lawyer can help if you're facing a dispute with the Society, have questions about a past order, or aren't getting a clear answer about your options.
