Yes. Bill C-452 creates an investigative power. The Competition Bureau does not have that power.
If you look at Bill C-10, it creates a power to prosecute and to impose fines, but not to investigate. If you want to prosecute and impose fines, you first have to be able to prove that the companies formed some kind of cartel. If you cannot investigate, then even with all the power in the world to impose fines, you will not be able to exercise that power.
