Last Updated: July 03 2026
Question: How does Denali Paralegal help me understand the process for requesting disclosure of third-party medical or counselling records in a criminal case in Ontario?
Answer: Denali Paralegal can help you understand how R. v. O’Connor, [1995] 4 S.C.R. 411 requires a defence to apply to the court first to show the third-party records are likely relevant to an issue at trial or to a witness’s competence, then the judge reviews the records and balances the third party’s privacy rights against the accused’s right to make a full answer and defence; if disclosure is ordered, the prosecutor must provide the relevant portions while protecting sensitive information where possible.

Decision Summary: R. v. O'Connor
The case of R. v. O'Connor, [1995] 4 S.C.R. 411, is a pivotal case heard by the Supreme Court of Canada that established important procedures in criminal proceedings concerning the disclosure of third-party records. This landmark decision has significant implications and impact upon privacy rights of third party persons as well as the right to a fair trial for an accused person.
Key issues addressed in this case include:
- Disclosure of Third-Party Records:
The question of how third-party records, such as medical or counselling records, should be handled when requested by the defence in a criminal trial. - Balancing of Rights:
The challenge of balancing the privacy rights of individuals with the right to make a full answer and defence of the accused person. - Judicial Procedures:
The processes and legal standards established to review and disclose such records.
Details and Insights
- Application by Defence:
The defence must apply to the court, demonstrating that the third-party records are likely relevant to an issue in the trial or the competence of a witness to testify. This application is a crucial first step that ensures the necessity of the records is established before any disclosure. - Initial Judicial Review:
The judge conducts an initial review to determine whether the records are "likely relevant." If deemed potentially relevant, the judge will order the records to be produced to the court for further examination. This step provides a preliminary check on the validity of the request. - Balancing Test:
The judge, once the records are received and reviewed, balances the privacy rights of the third party individual against the right to make full answer and defence as held by the accused person. This balancing test is vital to ensure that respect for the rights of all persons. - Disclosure:
The prosecutor, if the judge deems that such records are necessary for the accused to make a full answer and defence, must provide disclosure of relevant parts of the records. This step ensures transparency and fairness in the trial while protecting sensitive personal information as much as possible.
