We live in a democracy and it's ultimately up to the government of the day and our elected representatives to decide what the priorities are and how they're going to tackle them. I think the Prime Minister has also made that very clear with intelligence and national security. There are, of course, other examples, such as the Proceeds of Crime (Money Laundering) and Terrorism Financing Act, where the review is long overdue.
The first thing my students always want to do is change legislation. I always tell them that changing legislation is probably the single hardest thing you could possibly think of doing. Think of a tax incentive, policy or regulation—whatever. Don't try to change legislation, because you might spend a decade on it. You have to look for a politically opportune moment to bring in legislation such as this, Bill C-51 or others. Nonetheless, it keeps the attention on the matter. Otherwise, it just drops off the radar and nobody will pay attention to it until we run into some sort of crisis.
If we think that the first and foremost obligation of the state is the safety and security of the citizens and its political, economic and societal institutions, we need to have a mechanism to at least try to keep our eye on the ball. That's what I think these reviews do.
