Administrative law 2021 FCA 165

Canadian Security Intelligence Services Act (CA) (Re)

The appeal is dismissed: in the context of CSIS Act s.16 the words "within Canada" require that assistance and collection occur within Canada's geographic limits; where the proposed method would involve significant and legally consequential extraterritorial activity and probable breaches of foreign or international law the court may not authorize it under s.21; adaptation to technological change that would expand s.16 is a matter for Parliament, not the courts.

  • Meaning of "within canada" in csis act s.16
  • Warrant authority under s.21
  • Technological change and internet-accessible information
  • Interaction with foreign law and non-intervention principle
  • Parliamentary versus judicial role in national security policy
