5823-01723 — Impact Assessment Agency of Canada
The complainant alleged that the Impact Assessment Agency of Canada (IAAC) took an unreasonable amount of time to respond to an access request. The request was for communications related to designated projects in Western Canada. IAAC extended the response time by 880 days, but the Information Commissioner found that IAAC did not adequately justify the length of this extension, particularly under paragraph 9(1)(a) of the Access to Information Act. Consequently, the Commissioner deemed the extension invalid, ordered IAAC to respond by April 23, 2025, and found the complaint to be well-founded.
- Reasonableness of the 880-day time extension under subsection 9(1)(a) of the ATIA
- Whether IAAC demonstrated sufficient rigour in calculating the extension period
- Whether IAAC's delay constituted a deemed refusal of access under subsection 10(3) of the ATIA
Complaint well founded — disclosure ordered
The Commissioner found that the IAAC failed to demonstrate that the 880-day extension was reasonable, as required by paragraph 9(1)(a) of the Access to Information Act. Specifically, the IAAC did not provide a convincing explanation for its estimated monthly review rate or show sufficient rigour in determining the extension period. As a result, the extension was deemed invalid, and the institution was ordered to respond to the request by April 23, 2025.
