Investigation into the disclosure of an adopted child’s name to their biological mother by the Canada Revenue Agency

Canada Revenue Agency

This investigation examined allegations that the Canada Revenue Agency (CRA) inappropriately disclosed an adopted child's adoptive name, and the adoptive mother's personal information, to the child's biological mother. The OPC found that, on the balance of probabilities, the CRA likely disclosed the child's adoptive name, contravening section 8 of the Privacy Act. Deficiencies were also identified in the CRA's internal procedures for safeguarding adopted children's personal information. The complaint was found to be well-founded but not resolved, as the CRA agreed to implement some, but not all, of the OPC's recommendations.

Key Issues
  • Whether the CRA disclosed the child's adoptive name and the adoptive mother's personal information to the biological mother without consent.
  • Whether the CRA's internal procedures adequately protected the personal information of adopted children.
  • Whether the CRA's actions contravened section 8 of the Privacy Act.

5823-04210 — Canada Border Services Agency

Canada Border Services Agency

The complainant alleged that the Canada Border Services Agency (CBSA) did not conduct a reasonable search for Microsoft Teams messages related to ArriveCAN. CBSA's policy retains these messages for only 30 days, but an administrative error delayed the processing of the request beyond this period, leading officials to believe no records existed. Although CBSA later found one relevant record in its corporate repositories during the investigation, the initial delay meant a reasonable search was not conducted at the time of the request. The complaint was found to be well founded.

Investigation into the Canada Revenue Agency’s application of paragraph 22(1)(b) to refuse access to personal information

Canada Revenue Agency

The complainant alleged that the Canada Revenue Agency (CRA) improperly denied access to personal information related to five grievances, relying on exceptions under the Privacy Act. The OPC found that while the CRA conducted reasonable searches, it failed to adequately substantiate its use of paragraph 22(1)(b) of the Act to withhold information. Much of the withheld information was transactional and did not demonstrate a clear risk of harm upon disclosure. The complaint was found to be well-founded, but unresolved, as the CRA maintained its position on the withheld information.

Transport Canada

The complainant alleged that Transport Canada improperly withheld information related to rail workplace fatality investigation reports.

Canada Revenue Agency

The complainant alleged that the Canada Revenue Agency (CRA) improperly withheld employee time sheets under subsection 19(1) (personal information) of the Access to Information Act. The CRA claimed the information, related to a period of a labour strike, could identify employees who participated in the strike. The Information Commissioner found that while the User ID and PRI would reveal strike participation, the remaining time sheet data (date, attendance type, hours, etc.) did not meet the threshold for identifying individuals, as the CRA's evidence was speculative and the large number of employees made identification unlikely. The Commissioner ordered the CRA to disclose the information that did not meet the requirements of subsection 19(1).

Measures to anonymize sensitive polygraph records mitigated privacy impacts of NSIRA review

NSIRA Secretariat

This investigation examined complaints regarding the National Security and Intelligence Review Agency's (NSIRA) Secretariat's request for access to polygraph records as part of a review of the Communications Security Establishment. The OPC found that the anonymization measures significantly reduced re-identification risks, and the polygraph recordings themselves contained no personal information. However, concerns were raised about the timeliness of the Secretariat's requests to Treasury Board Secretariat for approval of Personal Information Banks (PIBs). The collection issue was found not well-founded, but the timeliness of PIB updates was found well-founded and subsequently resolved.
