    Stage 1 — File Opened

    A CAS File Has Been Opened — What This Means in Ontario

    When a Children's Aid Society (CAS) opens a file about your family, it means a concern has been reported and an investigation has started. This does not automatically mean your children will be removed — but the steps you take in the first days matter enormously.

    Key deadline: If a child is taken to a place of safety, within five days the matter has to be brought before a court or the child returned (Child, Youth and Family Services Act, 2017, s. 88). Do not wait for a court date to get information.

    What typically happens next

    • A CAS investigation starts within 12 hours of the referral when there is an imminent threat to a child's safety, or within 7 days when there is no immediate safety threat (Ontario Child Protection Standards, 2016).
    • The worker assesses whether children are at risk and determines the response level (immediate, 24-hour, or scheduled).
    • Parents are notified and have the right to know what the concern is about.
    • A safety plan may be discussed — this is not the same as a court order.
    • You may be referred to community services, parenting programs, or asked to agree to voluntary services.

    Step-by-step: what people in this situation often do

    1. 1

      Know your rights before the first visit

      You have the right to know the reason CAS is visiting. You are not required to let them in without a court order unless a child is in immediate danger. Ask to speak with a lawyer or duty counsel before making any agreements.

    2. 2

      Write everything down immediately

      Record every conversation with CAS workers — the date, time, who you spoke to, and exactly what was said. These records are your evidence if the case escalates.

    3. 3

      Contact legal aid or duty counsel

      Legal Aid Ontario provides free or low-cost family law representation. Duty counsel at the courthouse can help if a court date is imminent. You can call Legal Aid Ontario at 1-800-668-8258.

    4. 4

      Do not sign anything without understanding it fully

      Voluntary service agreements and safety plans can be used in future proceedings. Read carefully before signing. Ask for time to consult a lawyer.

    5. 5

      Start building your records

      Create a binder with all CAS correspondence, your parenting history, children's school records, medical records, and any evidence that shows your parenting capacity.

    Documents you will likely need

    • All written correspondence from CAS
    • Names and contact details of all CAS workers involved
    • Children's school attendance and grade records
    • Medical records for all children
    • Your rental or mortgage documents (showing stable housing)
    • Income or employment records
    • Character references from community members
    • Any prior court orders related to custody or parenting

    Frequently asked questions

    Does a CAS file opening mean my children will be removed?
    No. A file opening is the start of an investigation, not an outcome. Most CAS investigations result in voluntary supports rather than removal. However, it is important to take the process seriously and engage appropriately.
    Can I refuse to let a CAS worker into my home?
    You can decline entry unless the worker has a court order (warrant) or there is a child in immediate danger. However, refusing without explanation may escalate the concern. Consider speaking with a lawyer first.
    What is the difference between voluntary services and a court order?
    Voluntary services are agreed-upon supports that do not require court involvement. A court order is legally binding and comes from a judge. Do not confuse the two — signing a voluntary agreement is not the same as accepting a court order.
    How long does a CAS investigation take?
    Ontario's Child Protection Standards (2016) say an investigation is to be concluded within 45 days of the referral. When it cannot be, a supervisor can extend that to 60 days from the referral.
