Key takeaways
  • A children's aid society may refuse access to a record in specific situations set out in the CYFSA, including to protect the identity of someone who reported.
  • Even when part of a record is withheld, you still have a right of access to any part that can reasonably be separated from it.
  • The exact steps and timing for a request are best confirmed with the society or a lawyer.

If a children's aid society (CAS) has been involved with your family, or you were once a youth in care, you may want to see what is written about you. Records can help you understand decisions, prepare for court, or simply make sense of your own history.

This article explains in plain words what a CAS file is, what the Child, Youth and Family Services Act, 2017 (CYFSA) says about refusing access, and what to expect if some of it is withheld.

What a CAS file generally contains

A society's file is its record of its dealings with a child or family. When a society receives a report, it must, as soon as possible, carry out an assessment as prescribed and verify the reported information. Notes about that work, interviews and plans are the kind of material that may be in a file.

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. When kin are considered as caregivers, the society also documents its evaluation.

Your right to see your own record

Under the CYFSA, a service provider such as a CAS may refuse you access to your own record if access could reasonably be expected to lead to the identification of someone who was required by law to provide information, such as a person who reported under s. 125.

If access is refused for this reason, you still have a right of access to any part of the record that can reasonably be severed from the part that is withheld. How this applies to your own record depends on your situation, so it is worth confirming with a lawyer.

What may be withheld

A society may refuse access if it could reasonably be expected to identify someone who was required by law to provide information, such as a person who reported a concern. Anyone with reasonable grounds to suspect a child needs protection must report, even if the information is confidential or privileged.

Access may also be refused in other situations:

Partial access and blacked-out pages

A refusal does not always mean you get nothing. If a service provider such as a CAS withholds part of your record because access could reveal who reported under s. 125, you still have a right of access to any part that can reasonably be severed from the withheld part. This is why a record you receive may have some parts removed.

The protection for reporters has limits. No legal action can be brought against a person who reports under s. 125, but that protection does not apply if the reporter acted maliciously or without reasonable grounds for the suspicion. Whether that affects your situation is a question for a lawyer.

What to do next

Frequently asked questions

Can I find out who reported my family?

Not necessarily. A society may refuse access if it could reasonably be expected to identify someone who was required by law to provide information, such as someone who reported under section 125. How this applies depends on your situation, so it is worth confirming with a lawyer.

Can the society refuse to give me anything?

It may refuse access in certain situations, but you still have a right of access to any part of the record that can reasonably be severed from the withheld part.

Does a record from a court case count?

Access may be refused if the record was prepared mainly for a proceeding that has not ended. Ask your lawyer how that applies to documents in your case.

Is a report to the CAS confidential?

The duty to report applies even if the information is confidential or privileged, and a reporter is protected from legal action unless they acted maliciously or without reasonable grounds. A society may also protect a reporter's identity when access is requested.
