5823-03707 — Canada Post
The complainant alleged that Canada Post improperly withheld records related to a health and safety strategy report and invoicing, citing personal information, trade secrets, and confidential third-party information. The Information Commissioner found that Canada Post failed to demonstrate that certain information met the requirements for exemption under subsections 18.1(1) and paragraph 20(1)(b) of the Access to Information Act. Specifically, Canada Post could not prove the information was a trade secret, had a reasonable expectation of confidentiality, or was exclusively supplied by the third party. The Commissioner ordered Canada Post to disclose certain withheld information, and Canada Post agreed to comply.
