This chapter presents a case study examining the impact of Canada’s enhanced intelligence oversight framework—implemented since 2019—on the operational workload of national security agencies, specifically CSIS, CSE, and to a lesser extent, the RCMP. Drawing from open-source data, agency reports, legislative reviews, and comparative analysis with Five-Eyes partners, the chapter provides estimates in increased workload for the intelligence agencies. The study employs a structured methodology using qualitative and inferred quantitative indicators to assess the administrative and legal burdens created by new reporting obligations, internal audits, document preparation, and inter-agency communication. It also highlights the operational trade-offs faced by intelligence agencies, including resource reallocation and potential delays in core mission activities. While oversight has strengthened accountability and transparency, the chapter underscores the need for adaptive resource planning and performance-based evaluation frameworks to ensure that agencies maintain operational effectiveness under increased regulatory scrutiny. This case study forms part of a broader evaluation strategy aimed at balancing democratic oversight with the functionality of Canada’s intelligence apparatus in an evolving security environment.
