My part of a brief to the House of Commons Standing Committee on Public Safety and National Security, this paper endorses the proposed Canadian National Security and Intelligence Committee of Parliamentarians, but does so with an important caveat. In this last respect, it focuses on constraints imposed by bill C-22 on access by the committee to certain sorts of classified information. It raises concerns that these constraints may limit the effectiveness of the committee. Also contained in this document is annex comparing the proposed bill C-22 committee with analogues in the UK, Australia and New Zealand. The table in the annex includes details on: general features (such as membership and appointment); mandate and jurisdiction; reporting; access to information; and interface with expert review bodies.
