Disclosure to Interpol raises concerns regarding electronic transmission of personal information

Canada Border Services Agency

The complainant alleged that the Canada Border Services Agency (CBSA) improperly disclosed his personal information to his country of origin without consent. The CBSA disclosed a court judgment related to the complainant's criminal history to the High Commission of Canada to Ghana, which then forwarded it to Interpol for verification. The OPC found that while the disclosure was for a consistent purpose under the Privacy Act (enforcing immigration law), the CBSA's procedures for such disclosures were insufficient at the time, and the electronic transmission of information raised concerns.

Accidental disclosure by Health Canada - March 3, 2015

Health Canada

This investigation concerned a complaint against Health Canada (HC) regarding the mailing of 41,514 letters using windowed envelopes that revealed the name of the "Marihuana Medical Access Program" (MMAP). The Office of the Privacy Commissioner of Canada (OPC) found that HC contravened the Privacy Act by disclosing sensitive personal information without consent or legitimate purpose. Although HC cited administrative error and argued implicit consent or consistent use, the OPC determined that the sensitive nature of the program name required greater protection. HC has since implemented stricter mail-out procedures and created a new working group.
