CAS Investigation: Your Rights as a Parent in Ontario

If a Children’s Aid Society Knocks on Your Door

Few experiences are more frightening for a parent than being contacted by a Children’s Aid Society (CAS). Whether the call is a routine inquiry or the beginning of a serious investigation, what you say and do in the first few hours and days can have a profound impact on your family. This guide explains your rights, the investigation process, and how to protect yourself and your children.

What Is the Children’s Aid Society?

In Ontario, Children’s Aid Societies are private agencies funded by the provincial government and granted statutory authority under the Child, Youth and Family Services Act, 2017. Their mandate is to protect children from abuse, neglect, and harm. There are dozens of CAS agencies across the province, including Toronto, York Region, Peel, Durham, and Catholic and Indigenous-specific societies.

How Investigations Begin

CAS investigations almost always begin with a report from a third party. In Ontario, certain professionals — including teachers, doctors, social workers, and police officers — have a legal duty to report suspected child abuse or neglect. Reports can also come from family members, neighbours, or anonymous tips. The CAS is required to investigate any report it receives that meets a minimum threshold.

Your Rights During an Investigation

You have the right to know why CAS is investigating: CAS workers should explain the general nature of the concern, though they may not reveal the identity of the person who made the report.

You have the right to refuse entry to your home: Unless the CAS has a court order or police authorization, they cannot enter your home without your consent. Refusing entry is not by itself evidence of wrongdoing, though it may prompt the CAS to seek further authority.

You have the right to consult a lawyer: You can — and should — speak with a lawyer before answering questions, signing documents, or agreeing to any plan of care.

You have the right to record interactions: You can take written notes or, where lawful, audio-record meetings with CAS workers.

You have the right to challenge any apprehension: If a child is apprehended, the CAS must bring the matter to court within five days, and you have the right to legal representation.

What to Do — and Not Do — During an Investigation

DO:

• Stay calm and polite, even when frightened or angry
• Ask the worker for their name, agency, and contact information
• Ask what the specific concerns are and write them down
• Contact a child protection lawyer immediately
• Document everything in writing — dates, times, who said what
• Keep your children’s routines as stable as possible
• Cooperate within the limits of your legal rights

DO NOT:

• Sign anything without legal advice — even if it seems like just a “plan”
• Allow your child to be interviewed alone without legal advice
• Make spontaneous admissions or speculative explanations
• Discuss the case on social media
• Confront the person you suspect made the report
• Ignore CAS calls or visits — this can escalate matters quickly

Verbal Agreements vs. Formal Court Orders

CAS workers often ask parents to agree to informal arrangements — for example, that the children will stay temporarily with a grandparent, or that one parent will not be alone with the children. These “voluntary” agreements are not always truly voluntary, and they can later be used against you. Never agree to anything significant without first consulting a child protection lawyer.

When CAS Apprehends a Child

In serious cases, the CAS may take a child into protective care. This is called an apprehension. The CAS must bring the matter before a court within five days. At the first court appearance — called a Temporary Care and Custody hearing — you have the right to a lawyer and to oppose the apprehension. The court can order the child returned, place them with a relative, or place them in foster care while the investigation continues.

Legal Aid for Child Protection Cases

Ontario Legal Aid provides automatic eligibility for representation in CAS cases at the initial court stages, regardless of income. If you can afford private counsel, working with an experienced child protection lawyer often produces stronger results because of the time and attention private counsel can devote to the case.

Why This Matters to You

CAS investigations move quickly and the stakes — your relationship with your children — could not be higher. Even well-meaning, cooperative parents have lost custody of their children because they signed documents or made statements they did not fully understand. Getting legal advice early is the single most important thing you can do to protect your family.
