Key takeaways
  • A society must assess and verify a report, and it may interview a child with or without a parent's consent depending on the circumstances.
  • Any consent or agreement is valid only if you are informed, voluntary and have had a chance to get independent advice.
  • You may be able to see your CAS record, but parts can be withheld, including details that identify a reporter.

If a children's aid society (CAS) is looking into your family, you may be asked to answer questions, sign forms or let your child be interviewed. It is natural to wonder what you must do and what you may decline.

This article explains how Ontario's child protection law and standards deal with questions and interviews, and how to approach a conversation with a worker. It is general information, and a lawyer can speak to your own facts.

Why the society is asking questions

A society that receives a report must, as soon as possible, carry out an assessment and verify the reported information. Asking questions is how it does that. The Act also says help for parents should, where possible, be given on the basis of mutual consent, and the least disruptive suitable course should be considered.

Cooperating can help the society see your family clearly. How you should approach particular questions depends on your situation, so it is worth confirming with a lawyer. If the society cannot resolve its concern voluntarily, it may apply to the court to decide whether a child is in need of protection.

Can your child be interviewed without you?

Under the Ontario Child Protection Standards, a society may interview a child inside or outside the home, with or without the parent's or caregiver's knowledge or consent, depending on the circumstances. The standards say it is preferable to get the parents' agreement or give them notice. The standards do not name schools, and school boards have their own interview policies, so ask the school how it handles these requests.

Giving statements and signing agreements

Because the society has to verify the information it receives, it is sensible to be careful and accurate in what you say. How your own statements may be used later depends on your situation, so a lawyer can explain that. You can be polite and still say you would like to speak with a lawyer first. Taking time to get advice fits with the Act's requirement that an agreement be made after a chance to get independent advice.

If you are asked to sign a consent or agreement, the Act says it is valid only if the person has capacity, is reasonably informed, has had a chance to get independent advice, and acts voluntarily, without coercion or undue influence. That includes a decision to withdraw a consent. A temporary care agreement, for example, can last up to six months, and with a Director's written approval up to 12 months in total.

Seeing your file and learning who reported

You may ask for access to your own record. A society may refuse if access could reasonably be expected to identify someone who was required by law to provide information, such as a person who reported. Access may also be refused if it could result in a risk of serious harm, could identify someone who gave information in confidence, if the record is privileged, or if it was prepared mainly for a proceeding that has not ended.

Even then, you still have a right of access to any part of the record that can reasonably be separated from the withheld part.

What to do next

Speak with a lawyer early, before long interviews or any signed plan. If court proceedings begin, the Family Law Rules set a timetable, including a hearing within 120 days of the start of the case. The court may lengthen a time in the timetable only if the child's best interests require it, and the parties cannot lengthen it by consent. Gather your documents, such as school and medical records, and write out a timeline of events. Having them ready makes a conversation with a lawyer more useful.

Frequently asked questions

Do I have to answer a CAS worker's questions?

Whether you must answer a particular question depends on your situation, including whether a court order is involved, so it is worth confirming with a lawyer. A lawyer can also help you think through how to approach the conversation. The Act says help for parents should, where possible, be given on the basis of mutual consent. If the society is not satisfied, it may apply to the court.

Can CAS interview my child at school?

The standards allow a child to be interviewed inside or outside the home, with or without a parent's knowledge or consent, depending on the circumstances. They do not name schools, and each school board has its own policy.

Will CAS tell me who made the report?

It depends on the circumstances. A society may refuse access to a record if it could identify a person who was required by law to provide information, such as a reporter. You can still get any part that can be reasonably separated.

Is it a problem to ask for a lawyer?

Asking for advice before you sign is reasonable. A consent or agreement is valid only if you have had a chance to get independent advice and act voluntarily. If the society's concern is not resolved, it may still apply to the court, so a lawyer can explain how your choices may play out.
