It depends on what the mechanism that's placed in the act is, so there are a number of mechanisms for review in an act. In this particular case, depending on each of the three motions, each one of them has a different mechanism. For this one it says, “every five years after that, a committee of the Senate and the House of Commons as may be designated or established” following the coming into force.
So there would be a designation being done by the Speaker to a committee.
