Thanks very much for the question.
I do believe that it's instructive to look at some of the models that are out there. Judicial oversight certainly is an important protection. It is not the only protection. If you look at U.S. law, for example, it does require a federal judge to review before ordering a technical modification. The EU electronic evidence regulation explicitly states that any obligation to decrypt data or re-engineer systems for access is not part of the powers. The U.K. Investigatory Powers Act does include a judicial commissioner review.
None of those protections is available in Bill C-22. We recommend that a judicial review be a part of this, but it is perhaps not the only safeguard that could be added here.
