It is a new organization, but it's going to be built on the foundation of existing review bodies, which already have a high degree of expertise. The assumption here is that there would be a lot of initial briefings. We just saw that with the new committee of parliamentarians on national security. There are a lot of initial briefings to make sure everyone's familiar with mandates, how they work, reporting structures, and so on.
It's up to the committee whether you need to legislate that in, but it's kind of an obvious first thing you would do after royal assent.
