5820-01454 — Canadian Security Intelligence Service

Canadian Security Intelligence Service

The complainant alleged that CSIS failed to sufficiently identify which portions of the requested records were redacted and on what basis. CSIS used negative redactions and did not specify exemptions on the records themselves, claiming it could cause harm. The Information Commissioner found this insufficient, recommending CSIS provide a new response clearly identifying withheld portions and citing specific exemptions, cease using negative redactions, and cite exemptions on the records themselves. CSIS agreed to implement these recommendations.

The Information Commissioner found this insufficient, recommending CSIS provide a new response clearly identifying withheld portions and citing specific exemptions, cease using negative redactions, and cite exemptions on the records themselves.

Failure to publish a personal information bank description on Zero-Emissions Program contravenes the Privacy Act

Transport Canada

An individual complained that Transport Canada failed to publish a description of the Personal Information Bank (PIB) for its Incentives for Zero-Emission Vehicles Program. The investigation found that Transport Canada did not submit the PIB description for approval until 19 months after the program launched, and it was still not approved by the Treasury Board Secretariat (TBS) by the time the OPC's report was issued. Transport Canada has since confirmed the PIB has been approved and published.

Decision pursuant to 6.1, 2023 OIC 03

Human Resources sector of an unnamed federal institution

An institution applied to the Information Commissioner for approval to decline an access to information request, arguing it was vexatious and an abuse of the right to access records.

PIPEDA Findings #2023-001: Investigation into Home Depot of Canada Inc.’s compliance with PIPEDA

Home Depot of Canada Inc.

The Office of the Privacy Commissioner of Canada investigated Home Depot for disclosing customer email addresses and purchase details to Meta (Facebook) through Meta's "Offline Conversions" tool without valid consent. Home Depot used this tool to measure the effectiveness of its Facebook ads. The OPC found that Home Depot's privacy statement and Meta's policy were insufficient to obtain implied consent for this disclosure, as customers were not reasonably expected to understand that their data would be shared for these secondary purposes. Home Depot has since discontinued the use of the tool and agreed to implement recommendations for obtaining express consent should they restart the practice.

5819-00296 — Employment and Social Development Canada

Employment and Social Development Canada

The complainant alleged that Employment and Social Development Canada (ESDC) improperly withheld information related to Canadian universities' engagement in the Federal Contractors Program. The withheld information was claimed under sections related to personal information, confidential third-party commercial information, and disclosure restricted by another law.

As a result, the Commissioner ordered ESDC to disclose the information at issue, and ESDC indicated it would implement the order.

Trans Mountain Corporation (Re), 2023 OIC 01

Trans Mountain Corporation

The complainant alleged that Trans Mountain Corporation (TMC) improperly responded to an access request by invoking section 10(2) of the Access to Information Act, refusing to confirm or deny the existence of records, and indicating that any responsive records would be withheld under section 16(2) (facilitating the commission of an offence). The Information Commissioner found that TMC failed to demonstrate that the existence of records itself warranted withholding, especially since TMC had previously acknowledged similar records. Furthermore, TMC did not sufficiently establish that any responsive records would meet the criteria for exemption under section 16(2).

  • Whether the existence or absence of records can itself be information warranting withholding under the Act
  • Whether records could reasonably be expected to facilitate the commission of an offence under section 16(2)
  • TMC's inconsistent responses and blanket policy regarding record disclosure
