The complainant alleged that the time extension taken under paragraph 9(1)(b) (consultations) by the Canadian Security Intelligence Service (CSIS) to respond to a request under the Access to Information Act was unreasonable. CSIS showed that consultations with two other government institutions were necessary and could not reasonably be completed within 30 days. CSIS determined that an extension of 240 days would be required, considering the high classification level and sensitivity of the records, the need for on-site review of the records, and limited access to the workplace. The OIC determined that CSIS made a serious effort to determine the length of the extension based on the realities of the pandemic situation. The OIC concluded that the time extension was reasonable given the circumstances and that CSIS met the three requirements to claim the time extension. The complaint is not well founded.
