5823-02877 — Canada Revenue Agency

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).

Decision pursuant to 6.1, 2025 OIC 8

[the institution]

An institution applied under subsection 6.1(1) of the Access to Information Act for approval to decline to act on two access requests, arguing they constituted an abuse of the right to request information.

The Information Commissioner denied the application, finding the institution did not provide sufficient evidence to support these claims. The Commissioner noted the broad scope of the requests but concluded the institution failed to demonstrate they were an abuse of the Act.

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.

5821-01013 — Correctional Service Canada and Parole Board of Canada

Correctional Service Canada

The complainant alleged that Correctional Service Canada (CSC) improperly withheld records from an inmate's file, citing several provisions of the Access to Information Act, primarily subsection 19(1) concerning personal information. The investigation focused on whether CSC met the requirements for withholding personal information and if it reasonably exercised its discretion in denying access. The Commissioner found that the records contained sensitive personal information and that CSC had met the requirements of subsection 19(1). Furthermore, CSC reasonably exercised its discretion in deciding not to disclose the information, as the public interest in disclosure did not clearly outweigh the invasion of privacy. Consequently, the complaint was found not to be well-founded.
