Transport Canada (Re), OIC 2023 38

Transport Canada

The complainant alleged that Transport Canada improperly withheld portions of a Hazardous Occurrence Investigation Report concerning a Canadian National Railway (CN) employee's death, citing subsection 19(1) (personal information) and paragraph 20(1)(b) (confidential third-party information) of the Access to Information Act. The Information Commissioner found that certain information, such as train numbers, track numbers, and locations, did not meet the requirements for exemption under subsection 19(1) as their disclosure would not create a serious possibility of identifying individuals. While some information did qualify as personal information, Transport Canada failed to demonstrate it had properly exercised its discretion under paragraph 19(2)(c) regarding public interest disclosure. Furthermore, the Commissioner concluded that the institution and CN did not prove that the information withheld under paragraph 20(1)(b) met all four requirements of that exemption, particularly regarding confidentiality and public interest. Consequently, the complaint was found to be well founded, and Transport Canada was ordered to disclose the information not properly exempted.

3218-01867 — Natural Resources Canada

Natural Resources Canada

The complainant alleged that Natural Resources Canada (NRCan) improperly withheld information under various sections of the Access to Information Act in response to a request for records related to a specific contract. During the investigation, the Office of the Information Commissioner (OIC) narrowed the scope to NRCan's application of paragraphs 20(1)(b) and 20(1)(c). NRCan and the third party, Welund North America, failed to demonstrate that all requirements for these exemptions were met for most of the withheld information. The OIC found that only a void cheque and unit prices/quantities qualified for exemption. The Commissioner recommended that NRCan disclose all other information previously withheld under these paragraphs. NRCan made an additional disclosure but did not fully implement the recommendation. The complaint was found to be well founded.

Oct 1, 20232023 OIC 49Indexed Jun 30, 2026

Decision pursuant to 6.1, 2023 OIC 49

A federal institution

An institution sought the Information Commissioner's approval to decline to act on three access requests under subsection 6.1(1) of the Access to Information Act, arguing they were made in bad faith and constituted an abuse of the right of access. The requests sought all communications containing specific vulgar words over a three-year period. The institution claimed it had met its duty to assist the requester and that processing these requests would be unduly burdensome, requiring 4,068 employees to manually search for keywords and yielding thousands of non-relevant records, thereby hindering its ability to process other legitimate requests. The Commissioner found that the institution had fulfilled its duty to assist and that the requests, as framed, were an abuse of the right of access due to their breadth, the volume of requests submitted by the requester in a short timeframe, and the significant burden they would place on the institution, which would negatively impact other requesters. Consequently, the Commissioner granted the institution's application to decline to act on the requests.

5822-02031, 5822-02032, 5822-02033 & 5822-02034 — National Defence

National Defence

The complainant alleged that National Defence (DND) failed to conduct reasonable searches for records related to specific contracts under the Access to Information Act. The OIC investigation found that DND had not attempted to retrieve records from a third-party contractor, despite being entitled to them under the contract, nor had it searched paper records or a cloud-based platform. While DND initially argued the records were not under its control, it later conceded this point. As a result of the OIC's investigation, DND contacted the contractor and retrieved additional documents from the cloud platform. The Information Commissioner concluded that DND's initial searches were not reasonable. The complaints were found to be well founded, and DND was ordered to process the newly located records and provide new responses to the complainant.

Parks Canada (Re), 2023 OIC 26

Parks Canada

The complainant alleged that Parks Canada improperly withheld information under various sections of the Access to Information Act in response to a request for records related to Benga Mining or the Grassy Mountain Coal Project. The institution withheld information under subsection 19(1) (personal information), paragraphs 21(1)(a), (b), (c) (advice, consultations, plans), and section 23 (litigation privilege). During the investigation, Parks Canada disclosed a portion of the record initially withheld under paragraph 21(1)(a) due to the passage of time. The Commissioner found that the remaining information withheld under subsection 19(1), paragraph 21(1)(a), and section 23 met the criteria for exemption and that the institution had reasonably exercised its discretion. The Commissioner also addressed the complainant's concern about records marked as "not relevant," finding that Parks Canada was justified in not processing these records given the complainant's prior agreement to narrow the scope of the request. Despite upholding the institution's application of most exemptions, the complaint was found to be well-founded because the institution initially improperly withheld information under paragraph 21(1)(a) that was later released.
