The first thing I would note is that the location of this clause in 9.1 is such that the text of this clause would not actually go into the Criminal Code. It's a part of the bill, but it's not an amendment to the Criminal Code to insert this into the Criminal Code.
In theory, yes,“must” has the same challenges, in the sense that it raises the question of what would be the mechanism for enforcing it if it didn't happen. There's at least a timeline, so there's a period by which it has to happen. If it doesn't happen though, the enforcement mechanism is still uncertain.
