5819-02883 — Environment and Climate Change Canada
The complainant alleged that Environment and Climate Change Canada (ECCC) improperly withheld information under several exemptions of the Access to Information Act related to Taseko Mines Limited’s New Prosperity Project. The OIC investigated claims under subsections 16(2), 19(1), paragraphs 20(1)(d), 21(1)(a), 21(1)(b), and section 23. During the investigation, the complainant narrowed the scope, removing all information withheld under subsection 16(2) from the complaint. The Commissioner found that ECCC did not demonstrate that the requirements for paragraphs 20(1)(d), 21(1)(a), 21(1)(b), or section 23 were met for certain information. However, where the requirements for discretionary exemptions were met, ECCC was found to have reasonably exercised its discretion. The Commissioner ordered ECCC to disclose specific information that did not meet the exemption requirements. ECCC agreed to comply with the order, and the complaint was deemed well founded.
