Not every adoption in Ontario begins with a private arrangement between two families. Many children in the province are in the ongoing legal care of a Children's Aid Society, and a number of them are eligible to be adopted by a foster parent, a relative, or another approved adoptive applicant. Adopting a child from CAS care follows its own legal process — one that differs in several ways from a private or step-parent adoption.

This guide walks through who's generally eligible, what the process looks like in broad strokes, and how adopting a child already in society care compares to other adoption routes in Ontario.

Understanding "Extended Society Care"

Under Ontario's child protection legislation, a court can place a child in extended society care when a judge decides the child cannot safely return to a parent and no other plan is appropriate. While a child holds this status, the Children's Aid Society carries legal responsibility for them, and a parent generally no longer holds decision-making authority over the child. That earlier court finding is part of what makes a child in extended society care legally available for adoption — it isn't something an adoptive family arranges directly with a birth parent.

The Process, Step by Step

  1. Register your interest with a Children's Aid Society or licensed adoption agency and complete any required training.
  2. Complete a home study assessing your home, relationship, and capacity to parent.
  3. Be matched with a child whose plan is adoption.
  4. Begin a placement period, with the child living in your home before the adoption is finalized.
  5. Once the placement is going well, your lawyer files the adoption application in court.
  6. Attend the finalization hearing.
  7. Receive the adoption order and register it to obtain a new birth certificate.

What Changes Legally

Some adoptions from care also involve an openness arrangement — an agreement allowing some continued contact with birth family members after the adoption, where that's considered appropriate. Whether this applies, and on what terms, depends on the specific case.

Frequently asked questions

How is adopting from CAS care different from fostering?

Fostering is a temporary, licensed caregiving arrangement — the Children's Aid Society retains legal responsibility for the child. Adoption is permanent: it transfers full legal parentage to the adoptive parent.

Do I need a lawyer if the Children's Aid Society is already involved?

Generally, yes. A lawyer files the court application, makes sure the finalization paperwork is correct, and can answer questions specific to your matching and placement.

Can a birth parent contest the adoption after extended society care has been ordered?

Generally, the grounds to challenge an adoption at this stage are limited, since the earlier court process already addressed the birth parent's rights. A lawyer familiar with your specific file can explain what, if anything, applies in your situation.

Is there a cost to adopt a child from CAS care?

There's typically no agency placement fee, since the Society facilitates the process directly. Other costs — such as legal fees to finalize the adoption in court — still apply and vary by lawyer, so confirm current costs directly.
