Key takeaways
  • Anyone with reasonable grounds to suspect a child may need protection must report it, though this duty does not apply to children aged 16 or 17 unless a listed ground or prescribed circumstance applies, so a report alone does not prove anything.
  • Knowingly giving false information in a Part V application is an offence, but whether it applies to a particular report depends on the facts.
  • You can complain to the society, ask the Child and Family Services Review Board to review a decision, or complain to the Ontario Ombudsman.

Learning that someone has made a report about you to a children's aid society (CAS) is frightening, especially if you believe it is untrue or malicious. Many parents want to know two things right away: can the person who called be held responsible, and what can I do now?

This article explains how the process generally works in Ontario, what the law says about false information, and the practical steps people often take. Every situation is different, so a lawyer can look at your facts.

A report is not a finding

The law asks people to report when they have reasonable grounds to suspect a child is or may be in need of protection, and to do so immediately. This duty does not apply to children aged 16 or 17 unless a listed ground or a prescribed circumstance applies. The standard is suspicion, not proof. That is why a society may receive reports that turn out to be mistaken, exaggerated or unfounded.

After a report, a society worker assesses risk and urgency using the Ontario Child Welfare Eligibility Spectrum, and an investigation takes place where there are reasonable and probable grounds. Children's aid societies have the exclusive mandate to investigate.

Under the Child, Youth and Family Services Act, 2017 (CYFSA), a child is in need of protection only if the legal grounds are met. Examples include physical harm or risk of it inflicted by the person in charge of the child, or caused by a failure to adequately care for, supervise or protect the child. Serious emotional harm, or a risk of it, caused by a parent's actions or neglect is another ground.

Can the person who made a false report be held liable?

The CYFSA makes it an offence to knowingly give false information in a Part V application, punishable by a fine of up to $5,000, up to one year in jail, or both. Part V is the part of the Act dealing with child protection court proceedings.

Whether that offence, or any other area of law, applies to a particular phone call or report depends on the facts, including what the person said, what they knew and how it was used. A lawyer can tell you whether a specific situation could support a claim or complaint.

It also helps to keep the legal duty in mind. Because the law requires people to report suspicions, a report that proves unfounded is not automatically a false one. Intent and knowledge usually matter.

What you can do when a report has been made

If you disagree with how the society is handling things

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

If the matter reaches court, the law sets protections for families. The Act's paramount purpose is the child's best interests, protection and well-being, and it also calls for the least disruptive appropriate course of action and support for the family unit. A court must ask what efforts the society or others have made to assist the child. It cannot remove a child from the person who had charge of them unless less disruptive alternatives, including non-residential services and that assistance, would be inadequate to protect the child.

If you are served with a status review, a parent must file and serve Form 33B.1 (Answer and plan of care) within 30 days of receiving it. Missing a deadline can hurt your position, so get advice quickly.

What to do next

Whether the reporter faces any consequence is a separate question from whether your family is safe and supported. Most people find it best to put their effort into the child protection process first, and a lawyer can advise on the rest.

Frequently asked questions

Is it illegal to make a false report to CAS in Ontario?

The CYFSA makes it an offence to knowingly give false information in a Part V application, with a fine of up to $5,000, up to one year in jail, or both. Whether that offence, or any other law, covers a report or phone call made to a society depends on the facts, so it is worth confirming with a lawyer.

Will CAS tell me who made the report?

This depends on the circumstances and is worth raising with a lawyer. Your own communications with a lawyer stay privileged.

Does a report mean CAS will remove my child?

Not automatically. A report leads to an assessment of risk and urgency, and an investigation takes place where there are reasonable and probable grounds. In some cases a child under 16 can be brought to a place of safety, with a justice of the peace's warrant issued on reasonable and probable grounds that the child is in need of protection and no less restrictive course of action is adequate, or, if there would be a substantial risk to the child's health or safety while a warrant is obtained, without one. Within five days after that, the matter must be brought before a court, the child must be returned, or an agreement must be made. A court cannot remove a child from the person who had charge of them unless less disruptive alternatives would be inadequate to protect the child.

Where can I complain if I think the society acted unfairly?

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