Key takeaways
  • Outside urgent situations, a worker's removal powers depend on a warrant or court order.
  • A worker who believes a child under 16 faces substantial risk may enter without a warrant, by force if necessary.
  • Saying yes to a visit should be an informed, voluntary choice.

When a children's aid society (CAS) worker asks to come in, many parents wonder whether they can say no. The answer depends on what the worker is asking for and how urgent the situation is.

This article walks through when a worker needs a warrant or court order, the urgent exceptions, and how to handle the moment calmly. It is general information and not a substitute for advice about your own case.

The starting point: a visit versus legal authority

A society that receives a report must assess it and verify the information as soon as possible. A visit to your home is one way to do that. The Act also says help for parents should, where possible, rest on mutual consent, and that the least disruptive suitable course should be considered.

The Act's powers to remove a child, apart from urgent cases, depend on a warrant or court order. So there is a difference between a worker asking to look around and a worker who holds a warrant or order. Ask which one applies.

When a warrant or court order is involved

If a worker says they have a warrant or order, ask to see it and read it. Note the date, who issued it and what it authorizes. Then consider calling a lawyer right away.

When no warrant is needed

There is an urgent exception. A worker who believes on reasonable and probable grounds that a child under 16 needs protection, and that there would be a substantial risk to the child's health or safety in the time needed to get a warrant, may bring the child to a place of safety without a warrant. In that situation, a worker who believes on reasonable and probable grounds that the child is on any premises may enter without a warrant, by force if necessary, and search for and remove the child.

SituationWhat the Act says
Non-urgent concernRemoval powers depend on a warrant or court order.
Warrant issuedWorker may bring a child under 16 to a place of safety.
Substantial risk, no time for a warrantWorker may act without one and may enter premises.
Court application on noticeCourt may order the child produced, or direct a worker to take the child to a place of safety.

What refusing may lead to

Whether you can decline a voluntary visit is one question. What follows is another. A society may apply to the court to decide whether a child is in need of protection, and a worker who holds a warrant or order is in a different position from one who is simply asking. The Ontario Child Protection Standards (2016) also say 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, although it is preferable to get the parents' agreement or give them notice.

There is no single right answer. Some parents let the worker in with limits, such as a set time and having a support person present. Others prefer to arrange a visit after speaking with a lawyer. Either way, if you do agree, it should be an informed and voluntary choice, made with a chance to get independent advice.

What to do next

Frequently asked questions

Can I tell a CAS worker to come back later?

You can ask to arrange a different time. But if the worker believes on reasonable and probable grounds that a child under 16 needs protection, and that there would be a substantial risk to the child's health or safety in the time needed to get a warrant, they may bring the child to a place of safety without one. Ask what the worker's concern is before deciding.

Can a worker force their way in?

A worker who believes on reasonable and probable grounds that a child described in the substantial-risk rule is on the premises may enter without a warrant, by force if necessary. Outside that, removal powers depend on a warrant or court order.

What does a warrant actually allow?

It authorizes a child protection worker to bring a child to a place of safety. A justice of the peace must be satisfied on sworn information that the child is under 16, needs protection, and that a less restrictive option is unavailable or would not be enough.

What happens after a child is taken to a place of safety?

Within five days the child must be brought before the court, returned to the person who last had charge, or placed under a temporary care agreement or an agreement with a 16- or 17-year-old. A lawyer can explain which of these applies to you.
