5823-03707 — Canada Post

Canada Post

The complainant alleged that Canada Post improperly withheld information under subsections 19(1), 18.1(1), and paragraph 20(1)(b) of the Access to Information Act. The request sought a health and safety strategy report and related invoicing from DuPont Sustainable (DSS). The OIC found that Canada Post failed to demonstrate that the information withheld under paragraph 20(1)(b) met the requirements for confidentiality, third-party supply, or consistent confidential treatment. Similarly, for subsection 18.1(1), Canada Post did not show that the information constituted a trade secret or confidential financial/commercial information belonging to it, or that it was consistently treated as confidential. However, the OIC upheld the application of subsection 19(1) for personal contact information. The Information Commissioner ordered Canada Post to disclose the information improperly withheld under paragraph 20(1)(b) and subsection 18.1(1). Canada Post agreed to implement the order, and the complaint was found to be well founded.
