Timely review is built in. For instance, the Australians do this regularly, with an outside judge, every five years for the whole national security infrastructure. The problem we have in Canada is that we build in these mechanisms, but then the government of the day doesn't follow through, for any number of reasons.
Yes, a review, but there's also the question of what kind of review. Would it necessarily be a review within a parliamentary committee or would it perhaps be an outside review? Certainly, on these types of mechanisms, it will be worthwhile to look at whether the effects we intended to achieve are actually working to that particular end.
For me, the effect would be that of providing a rebalancing of the information asymmetry between Parliament and the executive.
